glGenTextures : PyOpenGL 3.0.2 GL Man Pages

generate texture names

Signature

glGenTextures( GLsizei ( n ) , GLuint * ( textures ) )-> void

glGenTextures( n , textures )

Generate count new texture names

    Note: for compatibility with PyOpenGL 2.x and below,
    a count of 1 will return a single integer, rather than
    an array of integers.

Parameters

Variables	Description
n	Specifies the number of texture names to be generated.
textures	Specifies an array in which the generated texture names are stored.

Description

glGenTextures returns n texture names in textures . There is no guarantee that the names form a contiguous set of integers; however, it is guaranteed that none of the returned names was in use immediately before the call to glGenTextures .

The generated textures have no dimensionality; they assume the dimensionality of the texture target to which they are first bound (see glBindTexture ).

Texture names returned by a call to glGenTextures are not returned by subsequent calls, unless they are first deleted with glDeleteTextures .

Errors

GL_INVALID_VALUE is generated if n is negative.
