webgl-path-tracer's Introduction

WebGL Path Tracer

[+] Next Event Estimation and Multiple Importance Sampling ported from LightHouse2
[+] Ordered BVH traversal algorithm implemented
[+] Multiple GL textures exploited for skydome and albedo textures loading
[+] GLTF file loading improved: multiple meshes with different textures support; few crucial bug fixes: do not calculate GL texture size at run-time
[+] Skydome sampling
[+] Base color and albedo textures support
[+] Geometry loading from GLTF files
[+] Improved user interface: website buttons to control actions such as changing scene, stop/resume rendering
[+] Scene camera controls via website buttons or keyboard
[+] GLSL shaders separated into external files
[+] Russian Roulette method to evaluate ray survival probability
[+] BVH acceleration structure implemented. Built on JavaScript side and then passed to the fragment shader via GL texture. Traversed using stack on the shader side.
[+] Randomize light based on seed {time, pixel coordinates, loop iteration}
[+] Pass scene triangles and lights to the shader via texture
