Poxels: polygonal voxel environment rendering

Miller, Mark; Cumming, Andrew; Chalmers, Kevin; Kenwright, Benjamin; Mitchell, Kenny

Abstract

We present efficient rendering of opaque, sparse, voxel environments with data amplified in local graphics memory with stream-out from a geomery shader to a cached vertex buffer pool. We show that our Poxel rendering primitive aligns with optimized rasterization hardware and so results in high visual quality over ray casting methods. Lossless run length encoding of occlusion culled voxels and coordinate quantization further reduces host data transfers
