Material

OpenGL OpenGL: Basic Coding

Hi,

can somebody point me to a collection of material types? I found one small collection (12 materials). Is there anywhere a bigger collection?
If this is not the case, can somebody please help me out with the material description for human skin?

Thanks very much,

Martin

Human skin is not an easy thing to represent in any graphics API (ie, renderman, rays, openGL etc).

OpenGL only has a simplified local illumination model (goraud shading). You can get some funkier stuff with pixel shaders and multitexturing. I’d recommend reading up on lighing models and try experimenting with openGL material/lighting properties.

Hi,

it doesn’t have to be that fancy. It is for a medical application, so a look alike is more then enough it only has to be pretty much the “right” color and the “right” reflection.
Could you give me an idea how to achieve a “right”, but not realistic look??

Thanks,

Martin
