🌎 Hello, World 🌍

This project takes an .obj file as input and renders the 3D object with texture mapping and bump mapping.

Built With

• C++
• Eigen library (for linear algebra)
• OpenGL (version 4.1.0)
• GLSL (version 4.10)
• GLFW

User Input

• 'u' scales the earth up
• 'd' scales the earth down
• 'r' to rotate the earth
• 'z' to spin the scene with the camera
• '-' to zoom out with the camera (perspective mode only)
• 'b' toggles between terrain bump map to bricks bump map
• can also change between orthographic and perspective projection in main.cpp

Texture Mapping

Two texture maps (daytime and nighttime) linearly interpolated depending on Phong shading computed at that point.

Bump Mapping

With topographical bump map:

With brick bump map:
