public class GraphicsInstructions
extends RenderInstructions

Class for passing the detailed rendering information for a single surface. from the sorter through to the renderable surface.

Since pBuffers cannot be shared across different GL contexts with the construct that JOGL is is using, when two parent textures reference a single child, there will be two copies of this class, with two different parentSource references, but only one copyOf set.

Field Summary

OffscreenBufferRenderable	parentSource Reference to the parent texture source that this instance is to be rendered into.
OffscreenBufferRenderable	pbuffer If set, the rendering should be done to an offscreen buffer that is then handed to this texture placeholder for use in another drawable object.
GraphicsEnvironmentData[]	renderData Visual data such as viewpoint, background etc.
GraphicsDetails[]	renderList The list of nodes in sorted order

Field Detail

renderData

public GraphicsEnvironmentData[] renderData

Visual data such as viewpoint, background etc. Initially assigned a length of 1.

pbuffer

public OffscreenBufferRenderable pbuffer

If set, the rendering should be done to an offscreen buffer that is then handed to this texture placeholder for use in another drawable object. If this is null, then render to the main on-screen drawable object.

parentSource

public OffscreenBufferRenderable parentSource

Reference to the parent texture source that this instance is to be rendered into. If the parent source is the root canvas (ie main drawable), this reference will be null.

renderList

public GraphicsDetails[] renderList

The list of nodes in sorted order

Constructor Detail

GraphicsInstructions

public GraphicsInstructions()

Construct a new instance of this class with the arrays initialised to a default size.

Method Detail

ensureEnvDataCapacity

public void ensureEnvDataCapacity(int reqdSize)

Resize the renderData variable to be at least the give size, copying existing contents if needed. If the array is already bigger than that requested, do nothing.

Parameters:

reqdSize - The number of elements required
