Google Earth Pro Price Drops From $400 To $0

Posted on by

Google announced last Friday that they were going to start offering their Pro version of Google Earth at no cost. The Pro version was meant mainly for developer, architects, contractors and real estate agencies who need both more advance measuring tools than the basic version offered plus higher resolution printouts.

 

 

Here is a table showing the differences between the two versions.

Unlike with the free version the Pro version allows you to measure diameters, heights and 3D paths and polygons.

How Accurate Is It?

I decided I’d test the measuring tools on something small to test the accuracy. I zoomed over to Colonial Williamsburg Courthouse which I built the model of years ago based on HABS surveys. The footprint measured out to be accurate within 99% and the height to within 98% accuracy. That’s pretty amazing.

3D Scanners For Your Pocket – Coming Soon, Very Soon.

There must be something in the water in Boulder. A lot of technology is coming out of that little town including two new devices which could continue to revolutionize the way we work. Location survey work has never been much fun and always comes with unknown challenges that often leave you stymied, ike that billboard you suddenly learn you have to measure, or the block-long row of buildings that you have to survey with two hours of sunlight left in the day.

Using 3D scanners for location surveying and object duplication in the past has been something people have wanted, but the price of most of these devices usually makes their use too cost prohibitive. The iPhone and the many apps that accompanied its popularity have been a real help in many Art Department workflows but their uses are currently limited as far as true 3D capture and augmented reality functions.

Two companies, Ike GPS and Occipital are trying to fill a need for low cost 3D scanners with two inventions which act as add-on devices for digital phones and tablets. By harnessing the power of these devices, their creations enhance products that most people are already using.

Ike is a company which has had previous success with hand-held scanners and was looking to create a device which could be small enough to fit on a smart phone. They’ve come up with a small device called Spike which attaches to an iPhone or other smart phone and uses the devices built-in accelerometer, compass and GPS functions to make it possible to measure the size, height or even the volume of buildings and even create a 3D model to export to a modeling program.

The company is currently running a Kickstarter campaign to raise interest as well as funds to develop the device which they plan on having ready for the market by next May. The device will come in two versions; the Basic version and the Pro version which will generate 3D model files, geolocate buildings and allow for pulling measurements from the digital image.

For a donation of $389, you’ll get a prerelease Spike Pro which the company says is around half of the final retail price, meaning the street price of the Pro unit is going to be somewhere in the $800 range. That may seem pricy but the next closest device I know of that can provide similar functions is about 5 times more,  both in size and price.

Here’s a video from the company website:

 

 

Occipital has developed a device they are calling the Structure Sensor which attaches to an iPad and can create 3D scans of objects or rooms up to about 550 square feet with a range of 3 1/2 meters. The file can be imported into a CAD package or output for 3D printing.

Structure Sensor

The Sensor Kickstarter program is fully funded but for a $330 pledge you can still get a Sensor at a significantly reduced price than it will retail for when it becomes available early next year.

For those of you who work in Sketchup and are new to rendering, or are confused by all the different rendering software packages available, a new book is coming out March 25 that will help. Daniel Tal, landscape architect and author of Sketchup For Site Design, has written a new book, Rendering In Sketchup, which is now available for pre-order or as a digital download.

rendering in sketchup

There are now a number of rendering programs on the market for use with Sketchup, with a majority of them working from within Sketchup without having to exit the program. This can be a plus or a minus depending on how you work. Even though most of the programs offer free-use trial periods of their software, It can be pretty difficult and time-consuming to decide which is  the best one for your workflow and budget.

Daniel is an excellent teacher and has written a very thorough and detailed book on the process of rendering from Sketchup using a variety of software programs as well as explaining post-rendering work with Photoshop. While not every rendering engine is covered, he does go into a great amount of detail explaining not only the basics of rendering, but his own methods using Shaderlight, SU Podium and Twilight Render.

The book covers workflow, hardware requirements, how to model efficiently for renders, use and teaching of textures and a lot more. At over 600 pages, the book is both a reference and a guide and can be read for pertinent chapters rather than just cover to cover.

You can get more information on the book here, and you can view the videos on Daniel’s Youtube site here

Here is a really good tutorial by Daniel you should watch which is based on the material from his book:

Understanding Model Scales – A Comparison Study

Posted on by

Comparative Scale Figure Diagram – You can download a pdf copy of this diagram below.

Even with the large number of computer 3D modeling programs available to designers, there is  (and I think always will be)  a place for physical scale models. Although the modeling programs continue to produce more and more realistic looking images, they are still only a 2D image that utilizes correct perspective. And even the programs or systems that are ‘true 3D’ are really only offset 2D images meant to trick the mind into thinking it’s seeing a dimensional physical shape.

Some of the advantages of a physical scale model are:

-The physical size of a set are much easier to grasp than from a digital model where you can zoom in endlessly.  I once built a model of an area of geography that the producers couldn’t seen to understand exactly how big an area it was until I put in the final piece, a model of the 260 foot ship they planned to use for a crew base. The huge ship measured only 3/16″ in the model scale. They got it instantly.

-A number of people are able to simultaneously view the model and discuss it. A lot of revelations often come from being able to look at a model from many different angles at once.

-The brain isn’t spending effort trying to do the mental tricks required to process fake 3D images. The model is somehow “more real”, because it is.

The Diagrams

I created the chart above as well as the list below from many years worth of notes and scribbles. The calculations are mine so any mistakes are solely mine as well. The visual chart will give you an easy way of determining the size of figures in the various scales that will be most common to concept models.

The list describes what I think are the most useful model sizes  from 1:700 to 1:6 with inch equivalents for each scale as well as the length of a linear foot and meter for each as well. The last column gives the common uses for the scale to help you determine what products exists for purchase. The Size Chart also lists the most common Imperial and metric drawing scales so you can find the model sizes that most closely match.

Determining The Size Of Your Model

Your first calculation will probably be how large the overall model needs to be. You’ll want the model to be as detailed as possible but probably won’t want it to take up and entire room. Using the Size Chart, multiply the overall actual size of the area you need to cover by the foot or meter equivalents and then determine which scale is best for the space you have available. Also note that 1/32 and 1:32 refer to the same scale.

Next, determine what model items exist in that scale. For the most variety in objects and vehicles, stick with the train gauge scales. If you need a lot of detailed plastic trucks or cars, 1/24th scale is going to probably be best, which is also the same as 1/2″ to the foot and is close to the German “G” train gauge.

The Future Of Sketchup

Posted on by

On Monday morning I, along with about 280 others, packed into the Boulder Theater in downtown Boulder, Colorado in the hope of finding answers. It was the first day of Sketchup Basecamp, a semi-annual event that attracts Sketchup users from around the world for a three-day conference that’s more like a cross between a family reunion and a college party than a traditional industry conference.

When it was announced on April 26 of this year that Google was planning to sell Sketchup, a lot of people ( myself included ) got more than a little nervous. Sketchup is the sole piece of software I use for modeling sets and creating working drawings. Since purchasing the program in 2006, Sketchup has become the most-used modeler in the world with it’s user base growing to over 30 million people. The program was obviously very successful, so why was Google selling it off when it normally doesn’t divest itself of products. The last time they had sold a product investment was in 2009. A Sketchup blog article by Product Manager John Baucus on the same day helped to allay fears but there were still a lot of unanswered questions and concerns.

Google had purchased Sketchup’s parent company, @Last Software in 2006 to provide content for Google Earth. The idea was to provide a free 3D modeling package that would allow people to create buildings for use in Google Earth. Even with a paid version of Google Earth it seems that Earth was never a profit generator for them and with the introduction of a new system which allows Google to now create models from auto-generated 3D mesh buildings from photo-grammatical data gathered from satellites and unmanned aircraft, it seems that they no longer saw a need for a 3D modeling program. There was speculation in the engineering industry that the company would be sold to Dassault Systemes, but when the announcement was made it was revealed that Sketchup would be purchased by Trimble Navigation.

Trimble Who?

So, who is Trimble Navigation and why did they buy Sketchup? It turns out Trimble is a billion dollar company located in Sunnyvale, California and is a leader in developing systems which use GPS technology for the surveying and construction industries. They have offices in over 30 countries and have over 1,800 patents relating to GPS systems. Sketchup is just just one of a number of acquisitions Trimble has made this year, including Tekla, a BIM modeling program from Europe. On Trimble’s website they describe the company as having integrated  “a wide range of positioning technologies including GPS, laser, optical and inertial technologies with application software, wireless communications, and services to provide complete commercial solutions. Its integrated solutions allow customers to collect, manage and analyze complex information faster and easier, making them more productive, efficient and profitable.”

Far from dumping the software in a fire-sale, Google wanted to make sure Sketchup went to a good home. Google had a previous relationship with Trimble having used their GPS systems in developing Google Earth.

Trimble Vice President Bryn Fosburgh was there in Boulder at the opening session to explain how they saw Sketchup’s position in the company’s structure. Having established itself in the engineering and construction side of the industry, the acquisition of Sketchup is seen as a way of extending the firm’s footprint into the design phase of the industries as well. He said they saw the modeling company as becoming seamlessly integrated with the other companies’ software and hardware products and said his only surprise after the purchase was getting used to the unusual dog-rich environment of the Sketchup offices.

Users of their products like the Robotic Total Station will be able to bring the file from a Sketchup model of a house into the device and have it’s laser lay out the corners of the building with 1 centimeter accuracy.

More Tasty Sketchup Biscuits To Come

A problem most companies have is learning when to leave acquisitions alone. Much like biscuits, where over-handling the mix leads to leaden,  inedible lumps. Trimble seems to have a record for buying quality companies, integrating them into the family, and then leaving the work to the people that know best how to implement it.

Joined on stage by Sketchup Product Manager John Baucus, Product Evangelist Aidan Chopra and a number of others from the company, the group quickly explained the plans Trimble has set for the 3D modeler: the program is going to stay simple to use, and it’s going to get a lot more complex as well. The company sees Sketchup as a platform as well as an application.

Here’s the abbreviated breakdown:

– There will always be a free version of Sketchup available and the basic program will     never be more complicated to learn.

-The Pro version will continue to be developed and you will see a continually greater difference between it’s abilities and those of the free version.

-They will continue to support 3rd party developers in creating compatible software and plugins to work within Sketchup. Over 45% of users have and use 3rd party plugins with Sketchup and they want to continue to support the creation of useful additions that they would never develop in-house, hoping that each industry will take the initiative in creating plugins for specific needs.

-They will continue to support “everyone else” as well. Since the program is used in so many varied industries and vocations, the company wants the software to be truly useful to anyone who uses it to create.

-They plan to continue to make the software run bigger and more complex models as fast as possible by any means they can.

-The company is ramping up their team size and is currently looking for new talent. Trimble is pumping a lot of money into the company, especially in Layout, their software for creating construction drawings from Sketchup models. They plan on continuing to improve the drawing program to equal any CAD package out there.

-Starting in 2013 with the release of the next version, the company will now go to annual updates instead of the random release dates we’ve become used to. Another sign that the software’s development is going to proceed at a much faster rate than it did at Google.

Also, there are plans to overhaul the 3D Warehouse. The Warehouse now contains over 2 million models with over 1000 new models added each week, many by major manufacturers. They plan to update it to make it easier to use and easier to find content.

And, it was announced that the company has developed an STL importer/exporter for creating model files for use in stereolithography and 3D printing. Now that companies like Makerbot have made desk-top 3D printers available in the $2000 range, 3D printing may soon become as common as paper printers.

They have licensed STL plugin code from three outside developers, streamlined it and offer it as a free plugin. You can download it here.

All in all, the switch to Trimble ownership looks like a much better fit than it did with Google. Although as John Baucus will say, plenty of good things came from the Google purchase. It was at Google that the free version of the software was launched and the 3D Warehouse came into being. And, kudos to Google for making sure the company went to a good new home and wasn’t just cut loose.

I don’t think I’m alone in saying that I left the conference relieved. It looks like Sketchup has a very long and productive future ahead. Aidan Chopra joked at the opening session, “Sketchup 17 is going to be awesome!”

Sculpting Tools For Sketchup

Posted on by

Most people think of Sketchup as a program that just draws boxes. As a poly-modeler it was always handicapped when it came to modeling compound curved surfaces and even with the built-in Sandbox tools, drawing terrain was never truly easy.

Now there are two different plugins that make not only terrain construction but organic and vehicle construction possible without having the urge to jump out the nearest window. I use both regularly and because they each have different attributes, I think their capabilities really complement each other when you are constructing complex shapes.

Artisan

The first is a plugin called Artisan which is a great solution for creating organic shapes. Created by Dale Martens, who has produced numerous other free plugins including Subdivide & Smooth, has created a set of sculpting tools that work very much like the sculpting tools in Maya and are incredibly easy to learn and use. The site has nice tutorial videos as well as a nice gallery of others work using the plugin. You have a series of settings which allows to to adjust the pressure of the brush, either positive or negative, and after setting the width of the ‘brush’, you drag it over the area to create the sculpted surface. The demo video below will give you an idea of the process.

One of the tools that alone is worth the $39 cost, is a poly-reducer which is a huge help when you import models from a NERB software package like Rhino or Maya. The tool allows you to select how much you want to reduce the poly count of a model to get it down to the size you need. You can also reverse the process and take a low-poly model and increase the detail.

I consider this plugin to be an absolute must for people who want to be able to build anything besides flat walls in Sketchup. Here are some examples of Sketchup models created using Artisan:

Motorbikes by Pete Stoppel

creature by Erik Lay

terrain by Pete Stoppel

Vertex Tools

The other plugin is called Vertex Tools. This program has tools which work differently than Artisan but has some advantages over it in the way the selection tools work. Designed by Thom Thomassen, a modelmaker from Norway who has also designed an incredible number of other useful free plugins, has designed a set of tools that are what the Sandbox Tools aspire to be.  At $20 it, like Artisan, is a real bargain. The video below will give you a quick overview.

The selection tools allow you to set how the tool affects the surrounding polys with either a linear or cosine fall-off. This one is really a must when you are creating terrain.

At a total cost of $59 dollars, these plugins will give you a huge boost in your modeling capabilities. If you use Sketchup, they should be your next purchase. You won’t be sorry.
