Function CreateLines

Creates a line mesh A line mesh is considered as a parametric shape since it has no predefined original shape. Its shape is determined by the passed array of points as an input parameter

• Like every other parametric shape, it is dynamically updatable by passing an existing instance of LineMesh to this static function
• The parameter points is an array successive Vector3
• The optional parameter instance is an instance of an existing LineMesh object to be updated with the passed points parameter : https://doc.babylonjs.com/features/featuresDeepDive/mesh/dynamicMeshMorph#lines-and-dashedlines
• The optional parameter colors is an array of successive Color4, one per line point
• The optional parameter useVertexAlpha is to be set to false (default true) when you don't need alpha blending (faster)
• The optional parameter material is the material to use to draw the lines if provided. If not, a default material will be created
• When updating an instance, remember that only point positions can change, not the number of points
• The mesh can be set to updatable with the boolean parameter updatable (default false) if its internal geometry is supposed to change once created
