@name Normalize, Length, and Inverse functions

Returns true if there is any item in the heap.

If max-heap, returns if the item at ix1 is smaller than the one at ix2. If min-heap, returns if the item at ix1 is greater than the one at ix2.

Returns the number of items in the heap.

Orthogonalizes the matrix and removes the scale component, preserving the x direction

Orthogonalizes the matrix and removes the scale component, preserving the z direction

Returns a project matrix with the tangent of the half field of view (tan_fov_2)

Returns the change in weight function radius using half of the number of samples. It is used for progressive sampling.
