All Implemented Interfaces:

Visitor

public class GLSLUpdateCache
extends GLDisplay.GLVisitor

GLSLUpdateCache is an Implementation of GLDisplay.GLVisitor. This visitor is used to traverse a Scene Graph. For each node it visits a reference is saved effectively transforming the graph into multiple arrays of graph-nodes. The nodes are sorted by their type into transparent material, solid material, tools labels and lightsources.

Constructor Details

GLSLUpdateCache

public GLSLUpdateCache(GLSLDisplay disp)

Constructor for GLSLUpdateCache. This is used to store a reference to the GLSLDisplay using this visitor. A reference is needed to gain access to the OpenGLState and the current Rendergraph-State

Parameters:

disp - The Display using this Visitor

Method Details

init

public void init(GraphState gs,
 Matrix4d t,
 int minPathLength)

Initializes the visitor for visiting a graph. This stores the inverse of the current WorldToView matrix.

Parameters:

gs -

t -

minPathLength -

• DisplayVisitor.init(GraphState, Matrix4d, de.grogra.imp3d.ViewConfig3D, boolean)

setCurrentTransformation

public void setCurrentTransformation(Matrix4d t)

Parameters:

t -

getRend

public int getRend()

Returns:

The number of renderable nodes found while traversing the graph

getAll

public int getAll()

Returns:

The number of all nodes visited during graph traversal.

visitImpl

protected void visitImpl(Object object,
 boolean asNode,
 Shader s,
 Path path)

Overrides:
