Efficient Space Skipping and Adaptive Sampling of Unstructured Volumes Using Hardware Accelerated Ray Tracing
A GPU volume renderer uses hardware ray tracing to skip empty and transparent regions and adaptively reduce sampling in low-variance regions of unstructured tetrahedral meshes, achieving 3.5x to 7.8x speedups at SSIM >= 0.97.
