glDepthFunc
glDepthFunc: specify the value used for depth buffer comparisons.
C Specification
void glDepthFunc(
GLenum func)
Parameters
func Specifies the depth comparison function. Symbolic constants
GL_NEVER, GL_LESS, GL_EQUAL, GL_LEQUAL, GL_GREATER,
GL_NOTEQUAL, GL_GEQUAL, and GL_ALWAYS are accepted. The
initial value is GL_LESS.
Description
glDepthFunc specifies the function used to compare each incoming pixel depth value
with the depth value present in the depth buffer. The comparison is performed only if
depth testing is enabled. (See glEnable and glDisable of GL_DEPTH_TEST.)
func specifies the conditions under which the pixel will be drawn. The comparison
functions are as follows:
GL_NEVER
Never passes.
GL_LESS
Passes if the incoming depth value is less than the stored depth value.
GL_EQUAL
Passes if the incoming depth value is equal to the stored depth value.
GL_LEQUAL
Passes if the incoming depth value is less than or equal to the stored depth value.
GL_GREATER
Passes if the incoming depth value is greater than the stored depth value.
GL_NOTEQUAL
Passes if the incoming depth value is not equal to the stored depth value.
GL_GEQUAL
Passes if the incoming depth value is greater than or equal to the stored depth value.
GL_ALWAYS
Always passes.
The initial value of func is GL_LESS. Initially, depth testing is disabled.
