Method Detail

clone

T clone()

Specified by:

clone in interface IData<T extends IVolume<T>>

Specified by:

clone in interface IValueCopy<T extends IVolume<T>>

transform

T transform(T volume,
            Mat4x4 matrix)

Parameters:

volume - a IBoundingVolume

matrix - a Mat4x4

Returns:

this = matrix * bv

concatenate

IVolume<?> concatenate(T other)

Concatenate this volume with other in a new IVolume object

Parameters:

other - a IBoundingVolume

Returns:

new concatenated volume

Volumes.concatenate(IVolume, IVolume)

interpolate

T interpolate(T bv1,
              T bv2,
              float t)

Description copied from interface: IInterpolable

Interpolate current and next and store result in this.

Specified by:

interpolate in interface IData<T extends IVolume<T>>

Specified by:

interpolate in interface IInterpolable<T extends IVolume<T>>

Parameters:

bv1 - a IBoundingVolume

bv2 - a IBoundingVolume

t - value in range [0;1]

Returns:

this = bv1 * (1 - t) + bv2 * t

addScale

T addScale(T bv1,
           T bv2,
           float t)

Parameters:

bv1 - a IBoundingVolume

bv2 - a IBoundingVolume

t -

Returns:

this = bv1 + bv2 * t

subtract

T subtract(T bv1,
           T bv2)

Parameters:

bv1 - a IBoundingVolume

bv2 - a IBoundingVolume

Returns:

this = bv1 - bv2

limitInVolume

Vec3 limitInVolume(Vec3 dst,
                   Vec3 src)

Limit a point in this volume. The point is displaced to the closest position (volume boundary) if it exceed this volume.

Parameters:

src - source point

dst - destination vector to store the result

Returns:

dst

getVolume

float getVolume()

Returns:

the volume of this IBoundable, in unit^3

intersectTest

IntersectTest intersectTest(T volume)

Parameters:

volume - another volume

Returns:

true if this and the specified volume collides

insideFrustum

boolean insideFrustum(Frustum frustum)

Returns:

true if the volume is inside the specified Frustum.

intersectTest

IntersectTest intersectTest(Frustum frustum)

Test the intersection between this IBoundingVolume and the specified Frustum.

Returns:

VolumeIntersection.Intersect if inside and intersect.
VolumeIntersection.Inside if inside but not intersect.
VolumeIntersection.Outisde if outside.

IntersectTest, insideFrustum(Frustum)

distanceToPlane

float distanceToPlane(Plane plane,
                      boolean min)

Parameters:

plane - a Plane

min - true: minimum distance
false: maximum distance

Returns:

negative value: volume intersect of is outside.
positive value: distance of the closest point
