Project Description
This is a basic future game engine for OpenGL 3D rendered games
Building on Windows
In order to configure and run project on windows platform accomplish several steps.
Configuring
cmake -S . -B build -G "Visual Studio 17 2022" -A x64 -DCMAKE_TOOLCHAIN_FILE=C:/vcpkg/scripts/buildsystems/vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-windows -DCMAKE_BUILD_TYPE=Release
Building
cmake --build build --config Release
Static Linking
For static linking you just need to modify the configure command as follows:
cmake -S . -B build -G "Visual Studio 17 2022" -A x64 -DCMAKE_TOOLCHAIN_FILE=C:/vcpkg/scripts/buildsystems/vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-windows-static -DCMAKE_BUILD_TYPE=Release
Multi-GPU Devices
If you want to use non-primary GPU on your device when launching the game specifically on Linux you should specify additional environment variables before running. For example in my case I have a hybrid gaming laptop with 2 GPUs AMD from CPU and NVIDIA discrete.
The run command in that case would look following:
__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia ./build/CodingGame
TODO List
Optimizations
🚀 Summary of Speedups
- Replace toElement / toMtlElement string comparisons with char-based switches.
- Replace std::stoi with a custom fast Parser::TakeIndex.
- Pre-reserve vectors for vertices, normals, texcoords, meshes.
- Load whole file into memory before parsing (fastest for large OBJs).
- Defer texture loading until after parsing.
- Store material pointers in meshes → no runtime lookups in render.
- Inline parsing functions.
