public interface Tesselatable
extends RenderObject

Represents an object which can be tesselated into a list of primitives such as a TriangleMesh.


Method Summary
 BoundingBox getWorldBounds(Matrix4 o2w)
          Compute a bounding box of this object in world space, using the specified object-to-world transformation matrix.
 PrimitiveList tesselate()
          Tesselate this object into a PrimitiveList.

Method Detail

tesselate

PrimitiveList tesselate()
Tesselate this object into a PrimitiveList. This may return null if tesselation fails.

Returns:
a list of primitives generated by the tesselation

getWorldBounds

BoundingBox getWorldBounds(Matrix4 o2w)
Compute a bounding box of this object in world space, using the specified object-to-world transformation matrix. The bounds should be as exact as possible, if they are difficult or expensive to compute exactly, you may use Matrix4.transform(BoundingBox). If the matrix is null no transformation is needed, and object space is equivalent to world space. This method may return null if these bounds are difficult or impossible to compute, in which case the tesselation will be executed right away and the bounds of the resulting primitives will be used.

Parameters:
o2w - object to world transformation matrix
Returns:
object bounding box in world space
