In this paper we present methods for reducing the CPU burden associated with the original implementation of the hardware-accelerated soft shadow volumes algorithm. We propose and implement two hardware-accelerated wedge construction methods: using the programmable vertex and fragment pipelines. New algorithms reducing the number of draw calls needed to render the shadow region (to three, two or even one) are also described. Tests performed using the current consumer level hardware show that our algorithms are no longer CPU-bound, and therefore can be over 2 times faster than the original algorithm.
