MassSpringSystem

An OpenGL implentation of mass spring animation.

Controls

• SPACE key -> toggles animation
• ENTER key -> steps through animation
• G key -> toggles gravity

Getting Started

These instructions will help with running the program.

Use this as the base compile instruction

g++ -o main main.cpp Particle.cpp Spring.cpp Vector.cpp -std=c++0x

OpenGL has platform specific flags so try these anywhere around "-o main" and after g++.

For Mac:

-framework Opengl

For Linux:

-lGL

For Windows:

-lopengl32

You will need GLFW installed to run this program. Just add the following if you have GLFW installed.

-lglfw3

Custom files

You can make your own files using this format:

• Line 1: Title (can be anything, will appear in window)
• Line 2: g
• Line 3: true or false (true for gravity, false for no gravity)
• Line 4: p n i

n = number of particles

i = which particle is static (-1 for none)

For each Particle:

• Line 4 + n: x y z w
• Line 4 + (n + 1): s m

m = number of springs

For each spring:

• Line 4 + m + (n + 1): i j k l

i = first particle index

j = second particle index

k = constant

l = rest length
