6 months in the making, but ShaderGraph 2 is now finally released. The last tweak was a diagram generator for debugging/documentation purposes.

This is what a MathBox 2 shader looks like. It's not as scary as it looks, the nameless blocks are mostly just transpositions or other one liners. Caveat emptor of course, but if this works for MathBox, it just might work for you too.

This is the glowing lines part of this demo: http://acko.net/files/dump/mathbox2/vertexcolor.html

MathBox², work in progress. Slides with inline notes from my talk at the SIGGRAPH WebGL BOF.

Are you still working on MathBox² +Steven Wittens?  Because it looks awesome.

Finished adding curved viewports to MathBox 2. The resulting test was so pretty it had to be a miniature demo. Chrome only for now, it's still alpha. (♫ Jeff Beal - House of Cards)

ditto. I'm working on more sophisticated particles too. At home, on the new integrated Intel graphics (HD4600) it ran with full 60 fps. Now at work on the HD3000 and under 10 fps at times, i see the lines more clearly now. very nice!

Slides for the presentation I gave at JSConf last week. (PS: Thanks Brian Leroux for suggesting it.)
\class{mj-purple}{\vec v'} = \mathbf{M'} \cdot \class{mj-orangered}{\vec v} = \mathbf{R} \cdot \mathbf{M} \cdot \class{mj-orangered}{\vec v} $$ $$ \begin{bmatrix} \class{mj-purple}{x'} \\ \class{mj-purple}{y'} \end{bmatrix} = \begin{bmatrix} \class{mj-blue}{-0.32} & \class{mj-green}{0.77} ...

For some reason it seems to be terribly slow on Safari 8, where as Chrome runs it just fine.

Beat me to the punch... native 4D in mathbox, because why not.

A guide on code-driven animation: physics, filters, splines and quaternions. And maybe some Star Wars.
Putting math into motion and controlling it precisely, with a little help from Isaac Newton and Admiral Ackbar.

OMG, this quaternion explanation is transcendently awesome.
