Crazy Mix Simulator

A physics based game made using C++ and OpenGL. Currently a renderer based off of my opengl framework.

Sketchfab GLTF model used: https://sketchfab.com/3d-models/spartan-armour-mkv-halo-reach-57070b2fd9ff472c8988e76d8c5cbe66

Building:

git clone --depth 1 https://github.com/snej55/mix_simulator.git
cd mix_simulator

# build it
cmake -S . -B build
cmake --build build/ -j$(nproc)

# to run
cd build
./main

Features:

• Physically based rendering
• IBL (Image Based Lighting)
• Skeletal animation
• GLTF Model loading
• Hybrid renderer (deferred for opaque meshes, forward for transparent)
• HDR (Khronos PBR Neutral Tonemapping)
• Bloom (PBR)
• SSAO (Screen Space Ambient Occlusion)
• Anti-aliasing (FXAA)
• Frustum Culling (AABB bounding volumes)
• Freetype2 font rendering
• Physics engine (Jolt)
• Cascading Shadow Maps
