Method Detail

tesselate
PrimitiveList tesselate()
Tesselate this object into aPrimitiveList
. This may returnnull
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 useMatrix4.transform(BoundingBox)
. If the matrix isnull
no transformation is needed, and object space is equivalent to world space. This method may returnnull
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
