Simple OpenGL Renderer

This is a very simple OpenGL renderer.

Features:

• Load OBJ files to display a spinning model
• Change rendering mode to various OpenGL modes
• Change camera distance to account for larger models
• A few OBJ files to load and play around with

Usage:

./main (obj_file) (GL_POINTS | GL_TRIANGLES | GL_LINES) (distance) [fps]

Parameters explained:

• ./main - The executable
• (obj_file) - The .obj file to render
• (GL_POINTS | GL_TRIANGLES | GL_LINES) - The mode to render the model with
• (distance) - The distance from the model itself
• [fps] - Optional argument to print FPS, time per frame, and total ticks

Example:

./main obj_files/teapot.obj GL_LINES 10

TODO:

• Fix OBJ loader to support quad faces (f 1 2 3 4 instead of just f 1 2 3)
• Cleanup code (specifically argument parsing and window management)
• Add lighting
• Maybe add a GUI (imGUI looks good)
• Improve makefile (maybe move to cmake)
• Add dependencies to repo (glfw, glew) instead of relying on system libs (low hanging fruit)
