	Please keep in mind that the following samples are my student projects from DigiPen and were not written with portability in mind. So although they should work on most Windows based PCs, there is no guarantee that it will work properly on machines different from that of developement.

Water Simulation : Download ( 2.1 Mb)

Description

This is a physics based water simulation I wrote for my CS461 Advanced Animation and Modeling 2 class. The water simulation uses the Chen Lobo Algorithm which is a discrete 2D version of the Navier-Stokes equation to simulate a water's surface. The implementation uses a 100 x 100 2D height field to represent water pressure at specific points and is contained within a "box" or fixed edge. The height field's normals are calculated each frame using finite differencing and is rendered with per-pixel lighting.

Cloth Simulation : Download ( 2.1 Mb)

Description

This is a physics based cloth simulation I wrote for my CS460 Advanced Animation and Modeling class. The cloth consists of 1250 point masses connected through a spring-damper system. There is constant wind and gravity being applied to the cloth.

Inverse Kinematics : Download ( 2.9 Mb)

Description

This is a basic example of Cyclic Coordinate Descent (CCD) Inverse Kinematics. This was done for my Advanced Animation and Modeling class. The actuator is contained within a 3D area in which you can move a box around on the ground plane. The actuator can reach to and follow the box much like a robotic arm reaching for an item.

Animation : Download ( 1.8 Mb)

Description

This is a simple frame based hierarchy animation done using Slerp interpolation for my Advanced Animation and Modeling class. Since I was using an existing DirectX framework I simply wrote my own version of DirectX's animation controller.

Bump Mapping : Download ( 0.2 Mb)

Description

This is a simple bump mapping demo done using ray casting. The demo was done for my Advanced Graphics class and is rendered entirely in software.

Phong Lighting : Download ( 0.1 Mb)

Description

A ray-cast Phong Lighting model done in the same framework as the bump mapping demo and was written for my Advanced Graphics class.

Hierarchical Occlusion Mapping : Download ( 0.1 Mb)

Description

This is my Hierarchical Occlusion Mapping demo done for my Advanced Graphics Class. The occlusion mapping determines objects to omit from rendering to decrease render costs. The occlusion mapping increases performance based on the number occluded objects.

Splines : Download ( 0.1 Mb)

Description

This spline demo renders both Bezier and De Boor curves based on user specified control points. This was written for my Curves and Surfaces class. A modified version of the Bezier curve is used in Empyreal Nocturnes to define movement path given waypoints.
