11. Audio reactive GLSL tentacles
7 months ago
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.
Music: "M" by Telefon Tel-Aviv.

Any chance that you'd be willing to post tentacle source code? I'm trying to achieve a similar effect to your tentacles and it seems to me that my method is a hack.

The code for this piece is not exactly the same, but it's the same principle and it's quite simple I think. The tentacles are just cones (gluCylinders) distributed on a spherical surface.
What are you having difficulties with?
