The space scene, then the stylized forest rendered with GPU instancing.

Overview

A real-time rendering project built for my MSc coursework at Newcastle University, in C++, OpenGL and GLSL. It opens on a space scene and moves to a stylized low-poly world with a forest, mountains and a building.

The code is structured with object-oriented design so each system stays modular. Forests are drawn with GPU instancing, and CPU-side frustum culling with sphere tests keeps off-screen objects out of the frame.

Highlights

  • GPU instancing draws whole forests of trees in a single draw call
  • CPU frustum culling with bounding-sphere tests
  • Deferred rendering with specular lighting
  • Post-processing in GLSL: saturation, desaturation and blur
  • Cel shading across the scene for the stylized look
  • Graded 74 out of 100
