Field Detail

BITHINT_BLENDING_ENABLEDback to summary
public static final int BITHINT_BLENDING_ENABLED

Bitfield hint, if set stating enabled GL#GL_BLEND, otherwise disabled.

Shall be set via setHintMask(int) and cleared via clearHintMask(int).

If set, GLRegion's draw-method will set the proper blend-function and the clear-color to transparent-black in case of multipass FBO rendering.

Shall be set by custom code, e.g. via RegionRenderer's enable and disable RegionRenderer.GLCallback as done in RegionRenderer#defaultBlendEnable and RegionRenderer#defaultBlendDisable.

BITHINT_GLOBAL_DEPTH_TEST_ENABLEDback to summary
public static final int BITHINT_GLOBAL_DEPTH_TEST_ENABLED

Bitfield hint, if set stating globally enabled GL#GL_DEPTH_TEST, otherwise disabled.

Shall be set via setHintMask(int) and cleared via clearHintMask(int).

GLRegion's draw-method may toggle depth test, and reset it's state according to this hint.

Shall be set by custom code, e.g. after RenderState or RegionRenderer construction.
