# Claude OF DUTY – a browser FPS with no art assets > Source: > Published: 2026-10-08 07:20:54+00:00 01 ### Renderer An HDR pipeline built by hand, not assembled from examples. Cascaded shadow maps with texel snapping and contact hardening, a depth and velocity prepass, ground-truth ambient occlusion, temporal anti-aliasing with variance clipping, motion blur, a Karis bloom pyramid, GPU metering and an AgX composite. 02 ### Materials A texture forge that runs on the GPU. Nineteen surfaces — concrete, brick, plaster, asphalt, sand, rusted and painted and brushed metal, wood, fabric, glass — with periodic noise so everything tiles, height-derived normals, parallax occlusion and curvature-driven edge wear. 03 ### Physics No library. A binned-SAH bounding volume hierarchy, a swept-capsule character controller with a five-plane crease stack, impulse rigid bodies with continuous collision, position-based ragdolls and multi-layer bullet penetration. 04 ### Audio Synthesised through the Web Audio API with no sound files at all. Layered weapon fire, convolution reverb, HRTF spatialisation and occlusion. 05 ### Sky Atmospheric scattering with a time of day, environment maps generated at runtime, volumetric fog and light shafts. 06 ### Agents Skinned soldiers with navmesh pathing, perception, cover behaviour and ragdoll deaths — the meshes and their textures generated like everything else.
