allocate-texture ( tdt level dim data -- )
GPU-accelerated rendering » Texture objects

Prev:	texture-data
Next:	update-texture ( tdt level loc dim data -- )

Vocabulary
gpu.textures

Inputs

tdt	a texture-data-target
level	an integer
dim	an integer or sequence of integers
data	a texture-data or f

Outputs
None

Word description
Allocates a new block of GPU memory for the levelth level of detail of a texture-data-target. If data is not f, the new data is initialized from the given texture-data object; otherwise, the new image is left uninitialized.

Notes
Using a buffer-ptr as the ptr of a texture-data object requires OpenGL 2.1 or later or the GL_ARB_pixel_buffer_object extension.
