This assignment, you are given two data files. The data files are a representation of a face object.
The two files are:
face-vertices.data:
every line of this file is (x, y, z) coordinates of a 3D points
face-index.txt:
every line of this file are 3 indices.
each index is an entry in face-vertices.data file referring to one vertex coordinate
so the 3 indices indicate 3 vertices of a triangle.
Write a program (python or any other program you prefer), to read this file and display the object in two mode:
- points: display all coordinates
- wireframe: display all triangles
do not use 3D library, instead, project the 3D coordinates to 2D screen yourself, using the perspective projection equations we talked about in class.
extra credit: interactive rotation and zoom in and zoom out.
