Method Details

appendToKey

public void appendToKey(@Nonnull
 KeyBuilder b)

Description copied from class: GeometryStep

Appends a key on the KeyBuilder that reflects any variety in the code that the geometry processor subclass can emit.

Specified by:

appendToKey in class GeometryStep

See Also:

• GeometryStep.makeProgramImpl(ShaderCaps)

makeProgramImpl

@Nonnull
public GeometryStep.ProgramImpl makeProgramImpl(ShaderCaps caps)

Description copied from class: GeometryStep

Returns a new instance of the appropriate implementation class for the given GeometryProcessor. This method is called only when the specified key does not exist in the program cache.

Specified by:

makeProgramImpl in class GeometryStep

See Also:

• GeometryStep.appendToKey(KeyBuilder)

emitVaryings

public void emitVaryings(VaryingHandler varyingHandler,
 boolean usesFastSolidColor)

Overrides:

emitVaryings in class GeometryStep

emitUniforms

public void emitUniforms(UniformHandler uniformHandler,
 boolean mayRequireLocalCoords)

Overrides:

emitUniforms in class GeometryStep

emitSamplers

public void emitSamplers(UniformHandler uniformHandler)

Overrides:

emitSamplers in class GeometryStep

emitVertexGeomCode

public void emitVertexGeomCode(Formatter vs,
 @Nonnull
 String worldPosVar,
 @Nullable
 String localPosVar,
 boolean usesFastSolidColor)

Description copied from class: GeometryStep

Emits the geometry code into the vertex shader. Implementation must define "vec4 worldPosVar" with the given name and setup it. If localPosVar is not null, then it must write geometry's local pos to it.

Overrides:

emitVertexGeomCode in class GeometryStep

emitFragmentColorCode

public void emitFragmentColorCode(Formatter fs,
 String outputColor)

Description copied from class: GeometryStep

Emits the fragment color code into the fragment shader. This is either paint's solid color or per-vertex primitive color. See GeometryStep.FLAG_HANDLE_SOLID_COLOR and GeometryStep.FLAG_EMIT_PRIMITIVE_COLOR.

Overrides:

emitFragmentColorCode in class GeometryStep

emitFragmentCoverageCode

public void emitFragmentCoverageCode(Formatter fs,
 String outputCoverage)

Remember that for DrawAtlas, we do not use texture swizzle, then the corresponding geometry step must handle the swizzle in shader code.

Overrides:

emitFragmentCoverageCode in class GeometryStep

See Also:

• DrawAtlas

writeMesh

public void writeMesh(MeshDrawWriter writer,
 Draw draw,
 @Nullable
 float[] solidColor,
 boolean mayRequireLocalCoords)

Overrides:

writeMesh in class GeometryStep

writeUniformsAndTextures

public void writeUniformsAndTextures(RecordingContext context,
 Draw draw,
 UniformDataGatherer uniformDataGatherer,
 TextureDataGatherer textureDataGatherer,
 boolean mayRequireLocalCoords)

Overrides:

writeUniformsAndTextures in class GeometryStep
