Methods
(static) getCentroid(positions, target)
Sets the target to the centroid position between all passed in
positions.
Parameters:
| Name | Type | Description |
|---|---|---|
positions |
Array.<THREE.Vector3> | |
target |
THREE.Vector3 |
(static) getWorldDistance(obj1, obj2) → {number}
Returns the distance between two objects.
Parameters:
| Name | Type | Description |
|---|---|---|
obj1 |
THREE.Object3D | |
obj2 |
THREE.Object3D |
Returns:
- Type
- number
(static) getWorldPosition(object, target)
Returns the world position of object and sets
it on target.
Parameters:
| Name | Type | Description |
|---|---|---|
object |
THREE.Object3D | |
target |
THREE.Vector3 |
(static) setQuaternionFromDirection(direction, up, target)
Takes a direction vector and an up vector and sets
`target` quaternion to the rotation. Similar to THREE.Matrix4's
`lookAt` function, except rather than taking two Vector3 points,
we've already calculaeld the direction earlier so skip the first half.
Parameters:
| Name | Type | Description |
|---|---|---|
direction |
THREE.Vector3 | |
up |
THREE.Vector3 | |
target |
THREE.Quaternion |
(static) transformPoint(vector, matrix, target)
Implementation of Unity's Transform.transformPoint, which is similar
to three's Vector3.transformDirection, except we want to take scale into account,
as we're not transforming a direction. Function taken from BabylonJS.
From BabylonJS's `Vector3.transformCoordinates`:
Sets the passed vector coordinates with the result of the transformation by the
passed matrix of the passed vector. This method computes tranformed coordinates only,
not transformed direction vectors (ie. it takes translation in account)
Parameters:
| Name | Type | Description |
|---|---|---|
vector |
THREE.Vector3 | |
matrix |
THREE.Matrix4 | |
target |
THREE.Vector3 |
