This is a simple technique to visualize the discreet curvature of mesh/poly/nurbs (All kind of objects) in 3ds MAX using Mesh controller in PARA . You also will learn how to use the custom attributes with parametric arrays.
Complex result can be achieved by linking two or more parametric array together. In this video we use PARA link controller to connect two independent array with a line segment. This can also be used in animation.
Mesh controller provides access to Mesh data of geometries from all kind. With mesh controller you can work with faces/edges and vertices of the meshes. A short example of using this feature has shown in this video.
This video shows the potential of using Loft object in Parametric array.
If you array a loft object PARA cannot find the information about the PATH object (base line) To get access to the vertices of the path object or deformation properties you need to animate the object before you use it.
This video shows that random controller can produce Boolean values (TRUE-FALSE). For each object in the array Random controller returns True or False based on the user defined percentage. Higher value makes the controller to return True more often and lower value causes more False result.You can make decision based on the result of the random controller through a condition controller . This process is similar to coin flipping.
This video demonstrate a very simple and quick technique which uses the surf-deform modifier and PARA 3d to clad a NURBS surface, if you work on patches you may use patch deform instead. In second video you learn how to use offset controller and sub-object controllers to slide the hexagon shape panels on the surface in a way that they make a honeycomb pattern.
In this video we use collection controller to find the position of those points which they are located on white sections of an image. The image is being process by a bitmap controller and if the value is greater than .5 (gray) the test controller returns true. collection controller goes through the entire array of points and collects only the position of the points which meets our condition. to set the position of each box to the corresponding point in collection we use a list controller. list controller takes the index value (location of the box in the array) and return the same item from the collection.
