Still more things, bits of info worth knowing (at least to me – now I know where I’ve written it all down):

• glTF is an up and coming format for transmitting 3D models, tailored for WebGL and OpenGL – they like to think of it as a 3D model codec. There’s three.js and Node.js support, as well as a Collada and separate FBX converter. There’s more explanation of glTF in the presentation at the WebGL BOF. Compression progress here, discussion here. (Thanks to Patrick Cozzi for these links.)
• I mentioned Shadertoy two days ago. I’ll mention it again! I’ve heard Iñigo Quilez’s youtube video channel has good tutorials on programming for Shadertoy, or just watch great demos (with no chance of locking up your GPU). Also, check this great Shadertoy illusion. My theory is every blog post should have a reference to Shadertoy, at least in my perfect world.
• The code for Epic’s Unreal Engine 4 is all open-sourced now. Best story for me at SIGGRAPH was of a guy who looked like a gang member coming to an Educator’s meeting and getting the signatures of some of the UE4 programmers, as he wanted to thank them for changing his life due to their code being accessible.
• Unity 4 is also free (including royalty free) for personal use (though not open source). Old news from March and GDC, but I realized I had only tweeted it, not blogged it.
• 3D printing. Yeah, it’s not graphics, but it’s close enough for me. The Computational Tools for 3D Printing course had a good introduction to the major types of 3D print processes, along with a useful walk down the software pipeline. BTW, I made a little page of links to 3D printing resources for beginners with an URL I can remember, bit.ly/info3dp
• I was surprised to learn that cross-site scripting attacks are 80% (by some measure) of all website security problems. A form of this type of attack was found and fixed back in summer 2011 for WebGL in Chrome and Firefox, with the concern that private textures from other sites could be read and copied by WebGL programs.
• Sketchfab has been adding cool new features, such as animation and object annotation (click horizontal arrows in lower right), as well as Oculus Rift support: just put “/embed?oculus=2” at the end of any model URL.
