Detailed Description

The class intended to place spheres in space and identify if there are spheres around. It is important for random objects generating and avoiding self-intersection of objects.

Examples

Constructor & Destructor Documentation

SphericalCollision()

coat::SphericalCollision::SphericalCollision

(

float

cellsize

)

create the collision space

Parameters

cellsize

the cell size that should be approximately around the average sphere size

Member Function Documentation

addSphere()

int coat::SphericalCollision::addSphere	(	const vec3 &	p,
		float	radius
	)

add the sphere into the space

Parameters

p	the position
radius	the radius

Returns

the sphere index, you may refer it later using the spher(index) function

Examples

TreesGenerator.cpp.

collides()

vec3 coat::SphericalCollision::collides	(	const vec3 &	p,
		float	radius
	)

check if sphere intersects other spheres in the space

Parameters

p	position
radius	radius

Returns

the repelling force, it is zero if no collision happened.

Examples

TreesGenerator.cpp.

setUnit()

void coat::SphericalCollision::setUnit

(

float

u

)

set the cell size, the cell space should be empty

Parameters

u	the cell size that should be approximately around the average sphere size

sphere()

vec4 coat::SphericalCollision::sphere

(

int

idx

)

get the sphere parameters by index

Parameters

idx	the sphere index (previously returned by addSphere)

Returns

the position (xyz) and radius (w) as vec4
