Class LightMatrix

java.lang.Object

codechicken.lib.lighting.LightMatrix

All Implemented Interfaces:

CCRenderState.IVertexOperation

public class LightMatrix
extends java.lang.Object
implements CCRenderState.IVertexOperation

Note that when using the class as a vertex transformer, the vertices are assumed to be within the BB (x, y, z) -> (x+1, y+1, z+1)

                                   int c,
                                   int d)

load

public boolean load()

Description copied from interface: CCRenderState.IVertexOperation

Load any required references and add dependencies to the pipeline based on the current model (may be null) Return false if this operation is redundant in the pipeline with the given model

Specified by:

load in interface CCRenderState.IVertexOperation

operate

public void operate()

Description copied from interface: CCRenderState.IVertexOperation

Perform the operation on the current render state

Specified by:

operate in interface CCRenderState.IVertexOperation

operationID

public int operationID()

Description copied from interface: CCRenderState.IVertexOperation

Get the unique id representing this type of operation. Duplicate operation IDs within the pipeline may have unexpected results. ID shoulld be obtained from CCRenderState.registerOperation() and stored in a static variable

Specified by:

operationID in interface CCRenderState.IVertexOperation
