Rendering

Hello scene The smallest complete scene: a floor, a spinning box and a sphere in the stock lit material, a sun and two point lights, shadows and an orbit camera TS WASM
Instancing A clone of square.felixmartinez.dev: a ball ploughs through a carpet of 16 384 cubes in one draw call, a compute shader moving each cube in the instance buffer it is drawn from TS WASM
Flowing cubes A swarm of textured cubes flowing on nested trigonometry, through SSAO, god rays and depth of field TS
Compute particles 300 000 particles moved by a compute shader and pushed around by the mouse TS

Cascaded shadows 4 000 instanced trees under a low sun, shadowed by four 2048² cascades with contact-hardening penumbrae, culled per cascade on the GPU TS WASM
Spot lights A car's headlights in a night forest: photometric spot lights with contact-hardening shadows from an atlas, shaded through clustered light lists and scattered in the fog TS WASM

Path-traced Cornell box The Stanford dragon in a Cornell box, path traced on the GPU against a BVH: in TS a hybrid tracer over the raster GBuffer, with compute-driven trails or a voxelized scene to trace instead TS WASM Reference Trails Voxels
GI Path traced Cornell A Cornell box under one downlight, its diffuse light path traced through a grid of the room's triangles (one ray for each 2 x 2 pixels, denoised), with a chrome ball and a glass ball ray traced through the same grid: reflection, refraction through both surfaces, frosted glass and rough chrome. Its panel switches to voxel GI, screen-space GI or a path-traced reference, and has the distance field, probes and the balls' roughness and index of refraction TS WASM Voxel + SSGI Voxel + SSGI
Outdoor GI The Raggare intro's forest, its 26 390 procedural spruces and birches, road and terrain fetched from raggare.kansei.graphics, under a low sun: voxel GI in a clipmap round the camera, screen-space GI or the hybrid ray-traced GI TS WASM Into the trees Into the trees
Voxel GI on particles Spheres of an SPH fluid raining into a lightbox under an emissive panel, splatted into a voxel volume and cone traced for their light, glowing ones lighting the rest over a glossy floor; the same demo in TS and Rust. Ray traced turns some into mirrors and glass, with depth of field TS WASM Ray traced Ray traced

Sky atmosphere A physically based sky from noon to dusk: Hillaire's LUTs, aerial perspective on distant hills, sky-lit surfaces and reflections of its prefiltered cubemap; the Rust one adds volumetric clouds TS WASM
Volumetric fog A grove of pillars under a low sun: froxel fog with shafts through the directional shadow, a lamp's cube shadow and a dim sky TS WASM
Curl volumetric Curl-noise particle trails through volumetric fog, in a Cornell box or over a scrolling noise terrain TS

Post-processing Spheres in volumetric fog with shadows and a filmic tone map, bloom on emissive surfaces, plus path-traced GI, depth of field and colour grading to switch on TS
Film look A dusk path in physical light units through fog, bloom and the tone mapper: EV100 exposure, filmic curves, vignette and grain TS WASM
Temporal AA Thin trunks, power lines, 12 000 swaying grass cards and a passing car: motion vectors and temporal anti-aliasing on a single-sample GBuffer; the Rust one can upscale and motion blur TS WASM
Depth of field Physical depth of field through a camera lens, two layers and scattered bokeh: in TS a scrolling field of noise-driven columns, some tops glowing, in Rust trunks, leaf cards and strings of lights TS WASM

Occlusion culling 60 000 spruces in three LODs, culled on the GPU per view by frustum, LOD band and, for the camera, a two-phase depth pyramid TS WASM
Impostors A lake ringed by 40 000 spruces whose far LOD is an octahedral impostor baked at start-up, mirrored in the water TS WASM
Cluster LOD A field of rocks drawn three ways: cluster LOD cut per cluster on the GPU, discrete LODs from the same graph, or the full mesh TS WASM Field
Meshlet inspector The Stanford dragon's 871 000 triangles in clusters, coloured by cluster, level, group or error against the budget, with the cut frozen while the camera flies TS
Planar reflection A lake at dusk mirroring the far shore, a lit cottage and a searchlight's beam in the mist: a mirrored view with an oblique clip plane, rippled and blurred by roughness; the Rust one has a screen-space mirror to compare TS WASM

Fluid A GPU particle fluid you can stir with the mouse, meshed by marching cubes and refracted TS WASM Nozzle
Lake Water held by a shaped bed and shore, stirred by a mill wheel's paddles, its surface drawn from a surface field; the Rust demo adds a course of boxes and a water cannon TS WASM
Fluid text 2D fluid particles that gather into letters TS
Fluid clock The time of day formed out of an SPH fluid, its digits pulling particles into extruded glyphs WASM
Steering text About 1 600 words flocking in 3D as boids, their letters trailing on distance constraints WASM

Skinning A ring of procedurally rigged tentacles skinned in their materials' vertex shaders, casting bending shadows TS
Motion matching A character controller over a course of boxes. The TS page needs a local animation pack (none ships) and shows the course alone without one; the live one on raggare.kansei.graphics walks, runs, jumps and wades through a fluid lake TS Live ↗

KTX2 textures ETC1S and UASTC textures and a glTF through KHR_texture_basisu, transcoded to the best format this device samples, with sizes and timings TS WASM
MSDF text Signed-distance-field text, animated by a compute shader TS
Video texture The webcam as an external video texture across 250 stacked instanced planes (asks for camera access) TS
