Field Detail

BITHINT_BLENDING_ENABLED

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.

Constant Field Values

BITHINT_GLOBAL_DEPTH_TEST_ENABLED

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.

Method Detail

createRenderState

public static RenderState createRenderState(Vertex.Factory<? extends Vertex> pointFactory)

createRenderState

public static RenderState createRenderState(Vertex.Factory<? extends Vertex> pointFactory,
                            PMVMatrix pmvMatrix)

getRenderState

public static final RenderState getRenderState(GL2ES2 gl)

id

public final int id()

getShaderProgram

isShaderProgramInUse

public final boolean isShaderProgramInUse()

setShaderProgram

public final boolean setShaderProgram(GL2ES2 gl,
                       ShaderProgram spNext)

Set a ShaderProgram and enable it. If the given ShaderProgram is new, method returns true, otherwise false.

Parameters:

gl -

spNext -

Returns:

true if a new shader program is being used and hence external uniform-data and -location, as well as the attribute-location must be updated, otherwise false.
