This is a quick experiment made with vvvv.

Just spinning spheres and moving textures.

Continuing my GLSL studies — now with dynamic lighting (vertex shader) and texturing (fragment shader).

This application runs at 35fps at 1280×720 pixel resolution on my ATI HD 4850 card. There are 1024 tentacles, drawn with gluCylinder — I guess this can still be optimized.

Made with OpenFrameworks v0.06 and GLFW.

Replaced the small spheres by cones distributed over the big sphere’s surface. Blur amount is controlled with the mouse.

Lightning the scene with the vertex shader.

My first GLSL -based animation. The blob is made of 3 glutWireSpheres deformed by applying a vertex shader. Deformation is affected by the music and mouse coordinates. In the code snippet below, fft is a value taken from ofSoundGetSpectrum and mult is the pair of mouse coordinates (x, y).

#version 120
uniform float fft;
uniform vec2 mult;
uniform vec3 col;
varying vec4 v;
void main()
{
    v = vec4(gl_Vertex);
    vec4 v2 = v;
    v.x += cos( v2.z * mult.x ) * fft;
    v.y += sin( v2.x * mult.y ) * fft;
    v.z += cos( v2.y * mult.x ) * fft;
    gl_Position = gl_ModelViewProjectionMatrix * v;
}
