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.

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.

Definition at line 81 of file ColladaParser.java.

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.

Definition at line 163 of file ColladaParser.java.

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 224 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.

Definition at line 275 of file ColladaParser.java.

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:

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
