Real-Time Continuous Level of Detail Rendering of Point Clouds

• a new technique for continuous level of detail generation of point clouds, designed for VF applications
• additive point storage, each point is assigned to one level
• compute shader used to iterate over all points, time-sliced over multiple frames, and builds a new vertex buffer that only contains required points
• each point is classified into distinct LOD levels + a random factor, this makes it possible to allow the set to be changed continuously
• points have a blend zone to reduce aliasing, in this zone point sizes are adjusted so that they gradually are blended to the final extent as the camera approaches the points

Reverse engineering the rendering of The Witcher 3, part 11 - lightnings

• explains how the lightning effect in The Witcher 3 has been implemented
• based on a tree-like mesh that is expanded based on the normals and additive blending

stable filtering — part 1

• explanation of half-pel filters
• shows properties of different filters common in video compression and how they perform when applied multiple times
• common filters are “unstable” when executed multiple times
• the feedback loop causes the results to be oversharpened until the results become unrecognizable
• presents a filter that does not have a feedback loop problem and converges to a slightly softened but stable result
