Struct
CoglDepthState
Description [src]
struct CoglDepthState {
/* No available fields */
}
Functions for describing the depth testing state of your GPU.
Instance methods
cogl_depth_state_set_range
Sets the range to map depth values in normalized device coordinates to before writing out to a depth buffer.
cogl_depth_state_set_test_enabled
Enables or disables depth testing according to the value of
enable.
cogl_depth_state_set_test_function
Sets the CoglDepthTestFunction used to compare the depth value of
an incoming fragment against the corresponding value in the current
depth buffer.
cogl_depth_state_set_write_enabled
Enables or disables depth buffer writing according to the value of
enable. Normally when depth testing is enabled and the comparison
between a fragment’s depth value and the corresponding depth buffer
value passes then the fragment’s depth is written to the depth
buffer unless writing is disabled here.
