nCine::GLScissorTest class
#include <nCine/Graphics/GL/GLScissorTest.h>

Manages the OpenGL scissor test state.

Static wrapper that caches the current scissor test state (GL_SCISSOR_TEST enable flag and the glScissor rectangle) so that redundant OpenGL calls are skipped when the requested state matches the cached one.

Public types

struct State: Holds the cached scissor test state.

Public static functions

static auto IsEnabled() -> bool: Returns whether the scissor test is enabled.
static auto GetRect() -> Recti: Returns the current scissor rectangle.
static void Enable(const Recti& rect): Enables the scissor test with the specified rectangle.
static void Enable(GLint x, GLint y, GLsizei width, GLsizei height): Enables the scissor test with the specified rectangle.
static void Enable(): Enables the scissor test reusing the cached rectangle.
static void Disable(): Disables the scissor test.
static auto GetState() -> State: Returns the whole cached scissor test state.
static void SetState(State newState): Restores the whole scissor test state.
