MatrixCloner

idpic1

The MatrixCloner clones and distributes given meshes in 3D space. If more than one mesh is provided, then the corresponding clones will be placed subsequently one after another starting in the x direction followed by y and z direction.
The MatrixCloner returns an object with an important property: root. It is an invisible mesh, it's the anchor and parent of all generated clones, its position is the middle position of all generated clones. Transforming this root affects all underlying clones (childs) at once. The given input meshes will be made inactive during construction, so after construction there will be only one of two possible mesh types: BABYLON clones or instances.
Note: Input meshes can be BABYLON meshes but other Cloners as well!

Example

Example of a LinearCloner with a count of 10 clones (5 x cube1, 5 x cube2) with an increment vector of {x:2,y:0,z:-1} :

var mc = new BABYLONX.MatrixCloner([cube1, cube2], demo.scene, { mcount: { x: 5, y: 5, z: 5 } });

Transforming of all clones can be done as you would do with a single mesh:

mc.root.scaling.y = 2; mc.root.rotation.x = Math.PI / 4;

Parameters

BABYLONX.MatrixCloner( meshes, scene[, {optional parameters}])

Mandatory Parameter Description
meshes array of meshes/cloners to be cloned, meshes will be made inactive after construction
scene BABYLON scene
Optional Parameter Description Default Value
mcount the nuber of clones in x,y and z direction { x: 3, y: 3, z: 3 }
size distance from one clon to another in x,y and z direction { x: 2, y: 2, z: 2 }
useInstances flag if clones should be technical "clones" or "instances" true
Properties Description
count READONLY, total number of clones after initialization
size @see Optional Parameter
mcount @see Optional Parameter
effectors READONLY, gets a list of Effectors assigned to this Cloner
Methods Description
addEffector(effector, sensitivity) adds an effector to this Cloner and sets the sensitivity (1=full sensitivity, 0=no sensitivity ==ignore effector)
setEnabled(flag) set the cloner's root node to the state of the flag (true=enabled)
