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

Prev:	allocate-texture ( tdt level dim data -- )
Next:	texture-dim ( tdt level -- dim )

Vocabulary
gpu.textures

Inputs

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

Outputs
None

Word description
Updates the linear, rectangular, or cubic subregion of a texture-data-target bounded by loc and dim with new image data from a texture-data tuple.

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.
