paulhoux / BallisticsIntegrator.as
Created September 27, 2011 10:02
AS3 sample that compares standard Euler integration to the performance of a Runge-Kutta-4 integrator. Based on an article by Glenn Fiedler: http://gafferongames.com/game-physics/integration-basics/ .
package nl.cowlumbus.integrator

/** An object with a position, velocity and acceleration. */
public class BallisticsIntegrator extends Object
{
private const force:Number = 10;
private const mass:Number = 1;
private var position:Number = 0;
private var velocity:Number = 0;

Example of using signals and slots with derived classes. Sample made for Cinder. Simply create an empty Cinder application called "Signals" using TinderBox, then replace the contents of ```SignalsApp.cpp``` with this code.

paulhoux / AudioShaderApp.cpp
Last active March 2, 2018 13:19
Adaptation of ShaderToy's AudioSurf shader for Cinder. Actual audio data is replaced with random noise to keep it simple. I kept the original shader code without making any changes. Note that ```iResolution``` must be passed as a Vec3f.

paulhoux / DebugMesh.cpp
Created January 24, 2014 22:55
Test application for the Cinder framework, showing that recalculated normals (based on the average of all connected triangle faces) is just as precise as the original normals (calculated from sphere mathematics).
