Superformula Vertex Shader 2.0
During my latest work time at meso in Frankfurt/Main i had the chance to chat with my old flatmate Sanch. One night around 3 o'clock we talked about further developement of the super formula vertex shader we released some month ago. The first version of the shader was quite simple: The input is a grid mesh with range -0.5 to 0.5 in both axis and a resolution of 20*20 vertices or higher. Inside the vertex shader the grid gets transformed by a regular matrix transform. This transformed grid is the "input space" for the 3D superformula which you can find on paul bourke's site. Gregsn did a great job, as he added the calculation of the normals for shading inside the shader.
Now the idea was to replace the matrix transform of the grid by another 2D superformula to get a more interesting input space. Sanch has implemented the idea and you can see the first promising results on his site. Download the first version of the shader at the vvvv shader site.
