NAME¶
al_clear_depth_buffer - Allegro 5 API
SYNOPSIS¶
-
#include <allegro5/allegro.h>
void al_clear_depth_buffer(float z)
DESCRIPTION¶
Clear the depth buffer (confined by the clipping rectangle) to the given value.
A depth buffer is only available if it was requested with
al_set_new_display_option(3alleg5) and the requirement could be met by the
al_create_display(3alleg5) call creating the current display. Operations
involving the depth buffer are also affected by al_set_render_state(3alleg5).
For example, if ALLEGRO_DEPTH_FUNCTION is set to
ALLEGRO_RENDER_LESS then depth buffer value of 1 represents infinite
distance, and thus is a good value to use when clearing the depth
buffer.

al_set_render_state(3alleg5), al_set_new_display_option(3alleg5)
