- the talk presents an overview of rendering features developed for Path of Exile
- showing what constraints the game provides and how it enables these implementations
- Point Light Shadows (Screenspace Hierarchical Variance shadow maps)
- Screenspace Global Illumination
- Subsurface refraction, a technique used for ice and water
- Water flow map generation on the CPU using Algebraic Multigrid
- grass and fur using pre-calculated raytracing
- an extensive collection of brief overviews of other techniques such as burning, fracturing, scalar field vectorization
- A virtual machine that is written in C enables executing of a subset of SPIR-V shaders (only 2D texture operations, no 3D etc.)
- presents operations that reduced the shading time required from 21.58ms to 13.52ms
- combination of scene-specific adjustments, implementation changes to noise generation and variance reduction
- A guide aimed at technical artists to preset best practices for geometry, texture, material and shader optimizations for mobile devices
- the article presents implementations optimizations to speedup trilinear filtering
- taking advantage of the representation of power floating-point number to speed up operations
- The database of articles included in this series has been updated with a new look
- this is the first step of a more extensive upgrade, and new functionality will be added soon. Stay tuned
