Empty Vessel Boy

Empty Vessel Boy was my open-ended final project for CalPoly SLO's Introduction to Computer Graphics course (CPE 471). The goal for this project was to create a hierarchical character model; animating and exploring in a 3-dimensional world.

When EVB is midair, you have control over its trajectory using the same forward and turn keys.

There are collision detections implemented so that you cannot walk/run off a platform. If you jump off of a platform, you can not run or walk around until you land on another platform again. On the platforms, there may be an elevated stage or poles positioned on them that you are prevented from walking into as well.

Animation

The animating is done by interpolating between predefined key humanoid frames using angles and normals set for every action. A timer is used to interpolate between the frames utilizing a given FPS macro.

Modeling

The humanoid was modeled using a system of rotations, translations and scaling to a 1 unit glusphere (except for the neck using a cylinder). Every limb is connected at a joint(sphere) representing where the limb can be both bent and rotated about.
