The linear algebra behind it runs on self-written 4x4 matrix and vector libraries.

Features

• Shapes from vertex data, textures and .obj model import
• Perspective projection with own matrix and vector library
• Movable camera and UI controls
• Phong and Blinn-Phong lighting: directional, point and spot lights
• Light maps and emission maps
• Outline shader with depth and stencil testing
• Transparency through blending, face culling
• Frame buffers, uniform buffer objects
• Cubemap skybox
• GPU instancing
• Anti-aliasing (MSAA)
• Scene switcher and automated frame-based scene tests
• Shadow mapping for point and directional lights
• Normal and parallax mapping
• HDR lighting with bloom
• Deferred shading
• Screen space ambient occlusion (SSAO)
• Physically based rendering (PBR)
