Introduction to Basic Scene Editor for 3D Model Manipulation

This assignment focuses on creating an interactive tool for basic transformations of 3D models using OpenGL, GLUT, and Win32. Students will learn to load .obj files, render basic geometry, and implement transformations such as translation, rotation, and scaling. Additional functionalities include rendering various appearances and applying lighting techniques. Students are required to document their efforts and challenges faced during the development process, emphasizing the importance of user interface and interactive selection within the editor.
