GLSL Starter

A starter OpenGL shader application written in C++ for Linux. It includes directional, point and spot lights, simulates ambient, diffuse and specular lighting as well as a shadow map with percentage closer filtering (PCF). It supports 3D model loading via Assimp and texture loading via STB Image.

Requirements

• OpenGL 3.3 and above
• GLEW
• GLFW
• GLM
• STB Image
• Assimp
