Snowboarder Animation

Jacob Serfaty's Intro to Computer Graphics final project

What did I do for this project?

For this project, I implemented two separate modules.

First, I added B, Bezier, Hermite, Cardinal, and Catmull-Rom splines (they are in interpolation.py). I then used these splines in my animation to make the snowboarder move.

Second, I added Least Square Conformal Mapping (they are in uv_mapping.py). I was originally going to use this to map all of my textures, but the requirement that the meshes had to have a disc topology made this way harder than I expected. I implemented another module to help with this (Seams, also in uv_mapping.py) that would allow you to easily edit meshes to give them disc topology without changing the shape of the mesh. However, though this worked for smaller meshes, I had trouble using it with larger meshes since I didn't know which edges to choose to make seams. I eventually settled on using this only for a small part of the animation: the texture of the snowboard.

My actual animation is just a snowboarder moving along splines and should be self explanitory.

The 3D models I used were all free and all of the materials that are applied to them came withe models. Note that the model for the girl who snowboards and the model for the mountains are both included in a Blender scene instead of in an obj file because for some reason, exporting them from blender ruins their materials.

How to run this project (assuming you have all of the libraries I used):

1. Clone this repo
2. Unzip Final Scenes and Objects/Snowy Mountain Scene.zip into Final Scenes and Objects
3. Run main.py
4. Run save_video.py
