Scene Renderer

Scene Renderer is a group project of Computer Graphics Course in Tongji University.

It is a renderer based on modern opengl, focusing on natural and in-door scene rendering.

Feature

Rendering

• Physically based skies
• Volumetric cloud
• PCSS soft shadows
• PBR Material
  • isotropic
  • anisotropic
  • clear coat
  • estimation of sss (gdc 2011: fast approximation)
• Reflective shadow maps
• Realtime Ocean
• Procedural Terrain
  • quad tree lod powered by GPU driven pipeline (GDC 2018)
• Deferred Pipeline
• auto exposure

Render System

• multi thread model loading
• asset loading from json files
• component based system

Modern Opengl

• improve datashader storage buffer + uniform buffer
• use compute shader to accelerate computation
  • quad tree traversal & mesh generatioin in procedural terrain
  • IFFT in ocean surface generation
  • Transmission map & sky-view lut computation in sky rendering

Gallery

• Sky & ocean
• Terrain
• House
• Path tracing component

Control

use w a s d to move, use e q to move up and down, hold shift to accelerate.

hold mouse right button to look around.
