We present in detail a compact data structure for storing voxels and an efficient algorithm for performing ray casts using this structure. Finally, we present a variable-radius post-process filtering technique for smoothing out blockiness caused by discrete sampling of shading attributes.

Efficient Sparse Voxel Octrees | Research

We augment the voxel data with novel contour information that increases geometric resolution, allows more compact encoding of smooth surfaces, and accelerates ray casts. We present in detail a compact data structure for storing voxels and an octres algorithm for performing ray casts using this structure.

We also employ a novel normal compression format for storing high-precision object-space normals. We augment the voxel data with novel contour information that increases geometric resolution, allows more compact encoding of smooth surfaces, and accelerates ray casts.

In this paper, we examine the possibilities of using voxel representations as a generic way for expressing complex and feature-rich geometry on current and future GPUs.

Based on benchmark results, we show that our voxel representation is competitive with triangle-based representations in terms of ray casting performance, while allowing tremendously greater geometric detail and unique shading information for every voxel.
