Linear Cloner

Table of contents



The LinearCloner clones and distributes given meshes in a linear manner. If more than one mesh is provided, then the corresponding clones will be placed subsequently one after another. The LinearCloner can instantiated in two different interpolation-modes: absolute and relative. In the first mode the values of the input parameters (scale/rotation/position) can be seen as the difference from the first to the last clone, whereas in the relative mode those values are the difference from clone to clone. The LinearCloner 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 position of the first clone. Transforming this root affects all underlying clones (childs) at once but independently of the interpolation mode. Most of the input parameters are also available as properties and they are very suitable for animation (tweening). 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 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 lc = new BABYLONX.LinearCloner([cube1, cube2], demo.scene, { iModeRelative:true,count:10,P:{x:2,y:0,z:-1} });

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

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

Animation can be done via properties:

BABYLON.Animation.CreateAndStartAnimation('ani', lc, 'offset', 30, 120, 0, 10);

root READONLY, getting an invisibe mesh representing the anchor of the cloner (root node)
