Using images for scaling and geometry patterns in SketchUp

Using images for scaling and geometry patterns in SketchUp

This post was actually inspired by a question in my Basecamp presentation: Could we use images to create or modify geometry in SketchUp? As it turns out, this is actually quite easy since SketchUp version 2018. This year's version of SketchUp includes a new class in Ruby, the ImageRep. Contrary to the regular Image class (which you can use to work with images as entities in SketchUp), the ImageRep class goes further and allows you to look at images on a pixel by pixel basis. This is basically what we need to be able to read pixel color values and then use those to create or modify geometry. As you can see in the code snippet below, this is reasonably straightforward once one figures out the basic geometric behavior. The code even stretches the image by the (x and y) dimensions of the selected geometry. One part that needed to be resolved was that color information in an image contains red, green, and...

Modeling and rendering my 2015 Christmas card image

Modeling and rendering my 2015 Christmas card image

Did you see my 2015 Christmas card tree image on this site? In case you were wondering how I modeled and rendered it, here is a video that explains that process. It's a bit of a minimalistic design, but as you can see in the video, I used a bunch of SketchUp extensions and the Twilight Renderer to make it happen. I hope you find the tips and tricks useful for your own projects. Covered topics: studio setup, materials, Erode extension, components, scale tool, Fredoscale extension, Selection Toys extension, Profile Builder extension, Twilight extension, Twilight materials, Twilight lights, Twilight rendering options. https://www.youtube.com/watch?v=HMBhhXavm48&feature=youtu.be...

Second edition of “Architectural Design with SketchUp” is now available!

Second edition of “Architectural Design with SketchUp” is now available!

I am very excited to be announcing the release of the second edition of my book "Architectural Design with SketchUp" today! For this edition, I went back through the text and updated and improved a lot of content. As before, my main goal was to keep it relevant for as large a variety of SketchUp users as possible and at the same time provide thorough yet easy to follow examples and tutorials. I am also very excited to announce a completely new chapter on physically making things with SketchUp that includes 3D printing, CNC cutting, and other techniques. Lots of fun stuff! As before, this second edition will use the companion website at http://sketchupfordesign.com/the-book where you can find free sample chapters, videos, references, 3D models, and tutorials.There are also now over 30 videos that accompany the book and can be accessed using the instructions in the book. Interested in getting the book? Check out Amazon or Wiley. Here's the official press release: 3D Modeling in SketchUp and Digital Making Come Together in Second Edition of “Architectural...

Merry Christmas, Happy Holidays and a Happy New Year 2014!

Merry Christmas, Happy Holidays and a Happy New Year 2014!

While Santa is getting settled in his new abode (looks like there is still some construction to do), it is time for me to wish you all wonderful holidays, a relaxing time with your family and friends and all the best for the new year! I hope to meet you, see you, email you or talk to you all again in 2014. Cheers, Alex P.S. As always, SketchUp was heavily used in the making of this picture. Santa came from the 3D Warehouse and yes, those are CLT panels....

Creating Photo Textures for Rendering

Creating Photo Textures for Rendering

As you just saw in the CLT example, having a good texture makes all the difference when you create renderings in SketchUp. I also discussed this in some length in the book (especially in the rendering chapter). To expand on this topic, here are some tips: Making a seamless texture Obviously a seamlessly repeating (a "tiling") texture is the most efficient way to go when you use textures. This allows you to use a small image to fill a large space. And if you use a good texture, you won't even see any seams or repeating patterns. As I described in the book, there are many places where you can get good quality tiling textures. However, what do you do when you need to make your own? First of all, start with a good image! This typically requires a few simple but important steps: Find the texture you are looking for (a brick wall, grass etc.). Be careful with the sun's position. If...
