  org.j3d.aviatrix3d.pipeline.graphics.MultipassDetails

public class MultipassDetails
extends java.lang.Object

Class for passing the detailed rendering information about a single multipass rendering set through the pipeline.

Multipass textures require information about the source, a callback to make between passes, as well as the texture object(s) that want to make use of this source.

Field Detail

globalData

public GraphicsEnvironmentData globalData

External rendering environment information that is applied to the entire setup. Typically this is used to contain just the main background and the viewport size. Individual per-pass environments are held in the data variable.

data

public GraphicsEnvironmentData[] data

External rendering environment information for each pass.

buffers

public BufferDetails[] buffers

The list of state renderables for each pass.

nodes

public GraphicsCullOutputDetails[][] nodes

List of processed nodes based on the scene they came from and the rendering pass to be processed. [a][b] where a is the rendering pass (numbered from 0 to n) and b is the nodes to be rendered in that pass.

numNodes

public int[] numNodes

Number of nodes in each rendering pass.

numPasses

public int numPasses

The number of valid passes to render this time.

Constructor Detail

MultipassDetails

public MultipassDetails()

Create a default instance of this bucket. All lists are initialised to null except the nodes variable, which is set to an internal default size. The graphics environment data is initialised.

MultipassDetails

public MultipassDetails(int numPasses,
                        int size)

Create a instance of this bucket with the node list initialised to the given size. All lists are initialised to null except the nodes variable, which is set to an internal given size and populated with the class instances. The graphics environment data is initialised.

Parameters:

numPasses - The number of passes to preallocate

size - The number of items in the nodes list to create

Method Detail

ensureCapacity

public void ensureCapacity(int numPasses)

Check and resize the lists if necessary to accomodate the requested number of passes.

Parameters:

numPasses - The minimum number of passes to have allocated
