A very large number of effects can be created by using voxels. It can of course be created in software and rendered by opengl, but something like a function that takes a pointer to a 3dvoxel field and rendered it to the screen would be nice. It's one step towards making it supported in hardware.

The texture3d extension or the 1.2 feature does not do volume rendering in the strict sense.

The original poster said something that I wanted and I'm voting for this one!

Something like

glBindTexture(GL_TEXTURE_3D, textureID);
glRenderVoxelfv(GLfloat *a_Cube);

is welcomed.
