Detailed Description

Function Documentation

wpTexture()

GLuint wpTexture ( void )

static

Gives handle to (and uploads if needed) weather particle texture; also binds it to the active texture unit.

Returns

OpenGL handle of texture object

Note

alas, image_t does not support anything but RGB(A) textures, so we've got to reinvent the wheel
