Nigul

Nigul is a graphics engine written in C++ using OpenGL. This project was created to provide a flexible and high-performance environment for implementing and experimenting with various graphics techniques. By using OpenGL, Nigul achieves greater speed compared to Vulkan while allowing extensive control over the graphics pipeline.

Nigul utilizes the following libraries:

• GLM for mathematical operations
• tinygltf for reading and writing GLTF files
• ImGui and ImGuizmo for creating and modifying scenes with a GUI
• stb for parallel texture loading (GPU upload is not parallel)

This engine was developed to apply interesting graphics papers and to provide a high degree of control over the graphics pipeline.
