Dallin Clark — Graphics Programmer

This project is a C++ and OpenGL based rigid body simulation tool that I developed.

It supports custom geometry, with object parameters for mass, density, elasticity, and gravity. It implements collision detection, collision point detection, and impulse based response.

Features

Rigid Body Dynamics Simulates 3D objects with variable properties — adjustable density, dimensions, restitution (bounciness), initial velocity, and initial transforms per object.
Dynamic Gravity Adjustable gravity strength and direction.
Broad and Narrow Phase Collision Detection Axis-aligned bounding boxes are used for the broad phase, and Separating Axis Theorem is implemented for the narrow phase. Sutherland-Hodgman clipping is used to detect collision points.
Impulse-Based Collision Resolution Realistic collision responses computed via impulse methods using Explicit Euler integration.
Static and Movable Objects Supports static immovable objects and active objects of any convex shape type.
