nCine::GLDepthTest class

#include <nCine/Graphics/GL/GLDepthTest.h>

Manages the OpenGL depth test state.

Static wrapper that caches the current depth test state (GL_DEPTH_TEST enable flag and the depth buffer write mask set with glDepthMask) so that redundant OpenGL calls are skipped when the requested state matches the cached one.

Public types

struct State

Holds the cached depth test state.

Public static functions

static auto IsEnabled() -> bool

Returns whether the depth test is enabled.

static void Enable()

static auto IsDepthMaskEnabled() -> bool

Returns whether writing to the depth buffer is enabled.

static void EnableDepthMask()

Enables writing to the depth buffer.

static void DisableDepthMask()

Disables writing to the depth buffer.

static auto GetState() -> State

Returns the whole cached depth test state.

static void SetState(State newState)
