switch_default_texmode

declaration:

switch_default_texmode(texmode) => nil

OpenGL exposes a number of different texturing mode flags for the st-uv coordinates which affects, among other things, sampling. This function changes how these are defined for newly created resources. This is a global state.

Allowed values are:
TEX_REPEAT TEX_CLAMP

and TEX_CLAMP is the default value. This means that any sampling outside 0.0-1.0 range, will be clamped to those values.

TEX_REPEAT is typically used in conjunction with scale- factored texture coordinates.
