In view mode:

1. mouse scroll for zoom in and out

2. mouse left for camera translation

3. mouse right for camera rotation

In draw mode:

mouse press to choose arbitrary points on mesh model (if intersection exists between mesh model surface and ray emitted from your mouse position ), currently with functions to find connecting points and find cutting vectors

obj_model.py:

load OBJ file and generate model object with vertices, normals, surfaces, texture coordinates information

camera.py:

camera setting for application window

triangle.py:

triangle class, used for ray-plane intersection

intersection_info.py

IntersectionInfo class, used to store information of intersection

ray.py:

do ray casting to find intersection bewteen mesh surface and ray emitted from mouse position

viewer.py:

application window
