What it does

Desktop: Left-click + drag to rotate, scroll to zoom, right-click + drag to pan. Hold Ctrl or use the checkbox to toggle brushing, and left-click + drag to paint while brushing. Touch: One finger drag to rotate, pinch to zoom, two finger drag to pan. Check the brushing mode checkbox to enable brushing. This is a WebGL implementation of the papers Object Space EWA Surface Splatting: A Hardware Accelerated Approach to High Quality Point Rendering by Ren, Pfister and Zwicker, and High-Quality Point-Based Rendering on Modern GPUs by Botsch and Kobbelt, with a few shortcuts. It also uses the deferred shading for splatting approach described in High-quality surface splatting on today's GPUs by…from willusher.io
