Class CL3D.OctTreeTriangleSelector

OctTree implementation of a triangle selector, useful for collision detection.

Extends CL3D.TriangleSelector.

Class Overview
CL3D.OctTreeTriangleSelector(Mesh, scenenode, minimalPolysPerNode, materialToIgnore, materialToIgnore2)
Implementation of TriangleSelector for huge meshes, useful for collision detection. The internal structure of this mesh is an occtree, speeding up queries using an axis aligne box (getTrianglesInBox). Every CL3D.SceneNode may have a triangle selector, available with SceneNode::Selector. This is used for doing collision detection: For example if you know that a collision may have happened in the area between (1,1,1) and (10,10,10), you can get all triangles of the scene node in this area with the TriangleSelector easily and check every triangle if it collided.
Parameters:
{CL3D.Mesh} Mesh
the CL3D.Mesh representing the geometry
{CL3D.SceneNode} scenenode
the CL3D.SceneNode representing the position of the geometry
{Number} minimalPolysPerNode
(optional) minmal polygons per oct tree node. Default is 64.
materialToIgnore
{Number} (optional) material type to ignore for collision. Can be set to null.
materialToIgnore2
{Number} (optional) material type to ignore for collision. Can be set to null.

Method Summary
Method Attributes Method Name and Description
 
Creates a clone of this triangle selector, for a new scene node
 
getAllTriangles(transform, outArray)
Returns all triangles for the scene node associated with this selector
 
Returns the scenenode this selector is for
 
getTrianglesInBox(box, transform, outArray)

Method Detail
createClone(node)
Creates a clone of this triangle selector, for a new scene node
Parameters:
node
{CL3D.SceneNode} scene node the selector is based on
Returns:
returns TriangleSelector if this selector can be cloned or null if not

getAllTriangles(transform, outArray)
Returns all triangles for the scene node associated with this selector
Parameters:
transform
{CL3D.Matrix4} a transformation matrix which transforms all triangles before returning them
outArray
{Array} output array of the triangles
Returns:
the new CL3D.TriangleSelector

getRelatedSceneNode()
Returns the scenenode this selector is for
Returns:
returns SceneNode if this selector is for a specific scene node

getTrianglesInBox(box, transform, outArray)
Returns all triangles inside a bounding box, for the scene node associated with this selector. This method will return at least the triangles that intersect the box, but may return other triangles as well.
Parameters:
{CL3D.Box3d} box
{CL3D.Matrix4} transform
a transformation matrix which transforms all triangles before returning them
{Array} outArray
output array of the triangles
