#include <subTex.h>

Inheritance diagram for glift::SubTex:

List of all members.

Detailed Description

SubTex - A sub-region of a larger texture that is treated as its own Glift texture.

SubTex can be used to make "virtual textures", where multiple SubTextures share the same memory space.

The StateGLI interface.

virtual void releaseDef ()

virtual bool isCompiled () const

void err (const char *where, const char *when=0) const

error

a simpler way, just use the stream! only for always print, this one automatically adds the objects name

void derr (const char *where, const char *when=0) const

debug error

bool glerr (const char *where, const char *when=0) const

gl error report only in debug mode, only if there is an error, if so return true
