Function Documentation

void Physics::applyFriction ( Ball * sphere )

Applies Friction to the sphere

Takes in the sphere and adds friction to its velocities

Parameters

Ball* the sphere to be updated

bool Physics::collisionCheck	(	Ball *	sphere1,
		Ball *	sphere2,
		float	dt
	)

Checks if 2 spheres collide

Takes in two spheres and a delta time and uses this to detect if the spheres collide

Parameters

Ball*	one of the spheres to be used in the collision
Ball*	one of the spheres to be used in the collision
float	the current delta time

bool Physics::collisionCheck	(	Ball *	sphere,
		Box *	wall,
		float	dt
	)

Checks if a sphere collides with a wall

Takes in a sphere, a wall and a delta time and uses this to detect if the two collide

Parameters

Ball*	the sphere to be used in the collision
Box*	the wall to be used in the collision
float	the current delta time

float Physics::distanceBetweenTwoSpheres	(	cgg::Vec3	sphere1Pos,
		cgg::Vec3	sphere2Pos
	)

Works out the distance between two spheres

Takes in two sphere positions and works out the distance between them

Parameters

cgg::Vec3	one of the position of the spheres to be used in the collision
cgg::Vec3	one of the position of the spheres to be used in the collision
float	the current delta time

float Physics::kinectInputVelocity	(	float	distance,
		float	time
	)

Works out the velocity from the kinect input

Takes in the change in distance and change in time from the kinect output and converts it to a velocity

Parameters

float	the change in distance
float	the change in time

void Physics::newCollisionVelocities	(	Ball *	sphere1,
		Ball *	sphere2
	)

Works out the new velocities after the spheres collide

Takes in two spheres works out the new velocities of the spheres

Parameters

Ball*	one of the spheres to be updated
Ball*	one of the spheres to be updated

void Physics::newCollisionVelocities	(	Ball *	sphere,
		Box *	wall
	)

Works out the new velocities after the sphere collides with a wall

Takes in the sphere and wall and works out the new velocities of the sphere

Parameters

Ball*	the sphere to be updated
Box*	the wall it has collided with
