Enumeration

CoglDepthTestFunction

Declaration

enum Cogl.DepthTestFunction

Description [src]

When using depth testing one of these functions is used to compare the depth of an incoming fragment against the depth value currently stored in the depth buffer. The function is changed using cogl_depth_state_set_test_function().

The test is only done when depth testing is explicitly enabled. (See cogl_depth_state_set_test_enabled())
