Sphere deformation
« on: September 25, 2011 »
Hi!

I'm new to the forum.... My first question is about sphere deformation. How does it work?
I'm working in C/C++ with OpenGL 2.0 and I know GLSL. Pseudo-code and formulas are good too.

Thanks for any info!

What do you mean about sphere deformation ?

Do you think about metaballs (look at wikipedia page so).
Or just deformation caused by a Scale Matrix ?

Take a look at Relsoft's "hematoma.zip" source that he kindly showed here, it uses Freebasic + Opengl.

It's based on spherical coordinates formula.

ALso you should look into Super Shapes created using the Super Formula its very robust and easy to understand

Speaking of supershapes and super formula, here's a morpher I made with the formulae:
