3-D Visualization in Blender

by ⋅ 4 Comments

I got a bit tired of the back end coding for the Multi-View branch and decided to tackle the frontend for a change.

Stereo Display Options

Stereo Display Options

Blender has a very modern drawing system (nicknamed Triple Buffer) which takes control over the buffer swapping routines (instead of relying on the graphic card Front/Back Buffer handling). That allows Blender to redraw the UI really efficiently. That also made the front-end implementation a breeze.

Now in User Preferences you can set the 3-D display you will be using with Blender. At some point I may make it a per-window option, but for now it will affect all the opened windows.

Next thing you need is a 3-D (Multi-View) image. You can simply render your own images (make sure the RenderViews are named “left” and “right”) or download a few OpenEXR samples.

3-D View

 

With no 3-D display set, when you open a 3-D image you should see the views in the Image Editor drop-down. When any 3-D display is set, however, you will see a new “3-D” option. Once this is set, you can take full advantage of your 3D-gear.

 

 

The following are samples from the other current display options. Be aware that the image I’m using doesn’t converge in a nice stereo 3-D photo. It’s in fact intentionally produced to show very different images, to make sure the code is working (programmers, go figure).

And not that you asked, but this was a great weekend for my 3-D philia. Iron Man 3 was a nice movie, and yesterday I attended two seminars at the SID – Display Week 2013 which turned to be quite inspiring talks with the addition of seeing some jaw-drop 3-D displays. I’m actually going there again tomorrow for the exhibit booth to see if I can clarify some pending questions that I have. I guess I should thank Queen Victoria for the long weekend 😉

Network Diagram – Aquaculture

I’ve been writing too much about coding, programming and other cool boring topics 😉

For a change I decided to share my current “desktop image”. This was part of the visualization I built for the AAAS 2013, for the Nereus Program sections.

The curves, spheres and the conformance of the visuals to an invisible translated-sinoide were all done with a Python addon I wrote for Blender. I will write more about this project one day.

The slightly yellow background (in oppose to pure white) is thanks to the great book: Visual Strategies: A Practical Guide to Graphics for Scientists and Engineers” by Felice C. Frankel and Angela H. Depace.

Multi View – 3D Stereoscopy in Blender – Development

by ⋅ 8 Comments

This video showcases the current snapshot of the multiview branch I’ve been working on.

Source Code: http://github.com/dfelinto/blender/tree/multiview

Original Proposal: http://wiki.blender.org/index.php/User:Dfelinto/Stereoscopy

For follow ups in the development I will keep posting in the bf-committers mailing list. But I will try to keep my blog up to date as well.

If you like my desktop background, this is the cover of my upcoming “Game Development with Blender” book with Mike Pan. The book is its final revision stage (checking the final pdfs about to be printed) and should be shipped soon. The pre-sale campaign on Amazon is still on-going.

Have a good day!
