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

        int getNumPrimitives()
        Returns the number of individual primtives in this aggregate object.
        Returns:
        number of primitives
      • getPrimitiveBound

        float getPrimitiveBound​(int primID,
                                int i)
        Retrieve the bounding box component of a particular primitive in object space. Even indexes get minimum values, while odd indexes get the maximum values for each axis.
        Parameters:
        primID - primitive index
        i - bounding box side index
        Returns:
        value of the request bound
      • prepareShadingState

        void prepareShadingState​(ShadingState state)
        Prepare the specified ShadingState by setting all of its internal parameters.
        Parameters:
        state - shading state to fill in
      • getBakingPrimitives

        PrimitiveList getBakingPrimitives()
        Create a new PrimitiveList object suitable for baking lightmaps. This means a set of primitives laid out in the unit square UV space. This method is optional, objects which do not support it should simply return null.
        Returns:
        a list of baking primitives
