Programming assignment 3: A visualizer for OBJ files
CS-116A: Introduction to Computer Graphics
Instructor: Robert Bruce

Objective

For this assignment, you will be creating an Alias/Wavefront OBJ file format visualizer using C or C++ with the OpenGL Utility Toolkit (GLUT). The specifications are outlined below.

Specifications

Your program must be able to properly parse vertex (v), face (f), and comment (#) data from an input OBJ file.

The OBJ files I'll be testing your program with ONLY contain vertices, faces, or comments.

Comments should be ignored by your program (everything from the # to the newline).

After reading in the OBJ file, your program should allow me to interact with the model using the following keyboard commands:

  • Pressing 'w' should display the OBJ file as a wireframe mesh.
  • Pressing 's' should display the OBJ file as a solid body model.
  • Pressing the up-arrow key should move the camera closer to the model.
  • Pressing the down-arrow key should move the camera away from the model.
  • Pressing the left-arrow key should rotate the camera counter-clockwise.
  • Pressing the right-arrow key should rotate the camera clockwise.
