Detailed Description

Connection between dae4j library and processing applet. Used to parse COLLADA (.dae) files and draw them on the processing applet. Also .kmz files are supported. These are exctracted to tmp dir and the dae file init will be loaded.

Member Function Documentation

static Appearance edu.tum.cs.vis.model.parser.ColladaParser.getAppearance	(	Material	mat,
		Collada	collada
	)		[inline, static, private]

Returns the instantiated Apperance by reading the material information from mat.

Parameters:

mat	Collada Material which holds information about the appearance
collada	Collada structure

Returns:

Instance of Apperance set according to mat.

static String edu.tum.cs.vis.model.parser.ColladaParser.getDaeLocation

(

String

tmpPath

)

[inline, static, private]

Tries to determine the location of the .dae file when a .kmz file was extracted. The path to the .dae file is stored in the doc.kml file withing the zipped kmz.

Parameters:

tmpPath

Path to the extracted .kmz file

Returns:

Absolute path to the .dae file or null if not found.

static String edu.tum.cs.vis.model.parser.ColladaParser.getNodeValue	(	NodeList	nList,
		LinkedList< String >	nodeNames
	)		[inline, static, private]

Searches in the given nList nodes tree for the node represented by nodeNames and returns the inner value of this node.

Parameters:

nList	the list of all nodes (returned by getElementsByTagName)
nodeNames	A linked list with the structure to search. The first name is the name of the root, the next name is the name of the child to search in the root and so on.

Returns:

The inner value of the node or null if not found

Definition at line 225 of file ColladaParser.java.

static ArrayList<Vertex> edu.tum.cs.vis.model.parser.ColladaParser.getVerticesOfMesh	(	Mesh	m,
		List< Input >	inputs,
		String	type
	)		[inline, static, private]

Get all vertices of mesh object m in an array.

Parameters:

m	the mesh object
inputs	list of all vertices
type	type of vertices

Returns:

list of all vertices which match given constraints.

boolean edu.tum.cs.vis.model.parser.ColladaParser.loadModel

(

String

filename

)

[inline, protected, virtual]

This function will be called from parseModel if the model isn't in the Buffer

Parameters:

filename

Physical file of model to parse

Returns:

true if model parsed successfully. false otherwise

Implements edu.tum.cs.vis.model.parser.ModelParser.

Member Data Documentation

String edu.tum.cs.vis.model.parser.ColladaParser.textureBasePath = "" [private]

Base path of the texture files. In the dae file are only relative paths. So we need a base. If kmz is parsed, this will be set automatically
