    The number of segments to build the cylinder out of

Methods

calculateLocalInertia

(
  • mass
  • target
)

Inherited from Shape but overwritten in src/shapes/ConvexPolyhedron.js:393

Parameters:

  • mass Number
  • target Vec3

calculateWorldAABB

(
  • pos
  • quat
  • min
  • max
)

Parameters:

clipAgainstHull

(
  • posA
  • quatA
  • hullB
  • posB
  • quatB
  • separatingNormal
  • minDist
  • maxDist
  • result
)

Parameters:

clipFaceAgainstHull

(
  • separatingNormal
  • posA
  • quatA
  • worldVertsB1
  • minDist
  • maxDist
  • Array
)

Clip a face against a hull.

Parameters:

  • separatingNormal Vec3
  • posA Vec3
  • quatA Quaternion
  • worldVertsB1 Array

    An array of Vec3 with vertices in the world frame.

  • minDist Number

    Distance clamping

  • maxDist Number
  • Array Object

    result Array to store resulting contact points in. Will be objects with properties: point, depth, normal. These are represented in world coordinates.

clipFaceAgainstPlane

(
  • inVertices
  • outVertices
  • planeNormal
  • planeConstant
)

Clip a face in a hull against the back of a plane.

Parameters:

  • inVertices Array
  • outVertices Array
  • planeNormal Vec3
  • planeConstant Number

    The constant in the mathematical plane equation

computeEdges

()

Computes uniqueEdges

computeNormals

()

Compute the normals of the faces. Will reuse existing Vec3 objects in the .faceNormals array if they exist.

computeWorldFaceNormals

(
  • quat
)

Updates .worldVertices and sets .worldVerticesNeedsUpdate to false.

Parameters:

findSeparatingAxis

(
  • hullB
  • posA
  • quatA
  • posB
  • quatB
  • target
)
Bool

Find the separating axis between this hull and another

Parameters:

Returns:

Bool:

Returns false if a separation is found, else true

getAveragePointLocal

(
  • target
)
Vec3

Get an average of all the vertices positions

Parameters:

Returns:

Vec3:

getFaceNormal

(
  • i
  • target
)

Compute the normal of a face from its vertices

Parameters:

  • i Number
  • target Vec3

getPlaneConstantOfFace

(
  • face_i
)
Number

Parameters:

  • face_i Number

    Index of the face

Returns:

Number:

pointIsInside

(
  • p
)
Boolean

Checks whether p is inside the polyhedra. Must be in local coords. The point lies outside of the convex hull of the other points if and only if the direction of all the vectors from it to those other points are on less than one half of a sphere around it.

Parameters:

    A point given in local coordinates

Returns:

Boolean:

testSepAxis

(
  • axis
  • hullB
  • posA
  • quatA
  • posB
  • quatB
)
Float

Test separating axis against two hulls. Both hulls are projected onto the axis and the overlap size is returned if there is one.

Parameters:

Returns:

Float:

The overlap depth, or FALSE if no penetration.

transformAllPoints

(
  • offset
  • quat
)

Transform all local points. Will change the .vertices
