RayTracer

CPU Ray Tracer

Author: planet620

Cornell box scene finalized
Static mesh rendering
- Backface detection for transparency
- No acceleration structude ofr triangles yet
- No static mesh assets yet
ISPC integrated with the project and used for basic
Better compile times
CppCheck and BuildInsights pass
Huge code refactor
Better logging with spdlog

Full scene editor
- Flying camera
- Object selection and movement
- Material editor

The same set of materials and primitives
Renderer interface, with example and reference CPU renderer, easy to hot-swap with another version
Simpler algorithm, no PDF in use
Refraction with smoothness
Coloured refraction
Gloss with smoothness

Based on books: Ray Tracing in One Weekend by Peter Shirley

Editor UI
- Scene setup: spawn/delete/move/edit object properties
- Render parameters
- Settings
- Real time output update
- Save output to BMP file
Renderer
- Monte Carlo based method, mix of light and surface cosine based probability density functions (PDF)
- Multithreading: thread poll, PLL, none
- Support for SIMD
- DirectX 11 based display
- Anti aliasing
- No denoising
- Starting code for the review: frame_renderer::render() and frame_renderer::ray_color()
Renderer variables
- Resolution
- Work distribution: stripes, chunks
- Rays per pixel, ray bounces
Camera setup
- Projections: Perspective/orthografic/blend
- Focus distance
- Aperture
- Aspect ratio
Specular, diffuse, emissive materials:
- Metal: copper, gold, silver, steel
- Dialectric: glass, sapphire, moissanite, diamond, water
- Texture: solid, checker
- Lambertian: basic colors
- Diffuse light: a few strength types
Primitives:
- Sphere
- XY rectangle
- XZ rectangle
- ZY rectangle
