Tutorial: Away3D TypeScript: Primitives – Wireframe Plane

This is a quick overview tutorial of the WireframePlane primitive in the Away3D TypeScript library.

We will be recreating the scene as seen above.

To use a WireframePlane primitive, we’ll need to:

  • Declare, instantiate, and initialize a new WireframePlane object.
  • Add the WireframePlane object to the scene.

Notice, we do not place the wireframe in a Mesh object. This is because a Mesh would be overkill, trying to apply materials, shaders, and what have you. So just add the wireframe object as a child of the scene itself.

This tutorial builds off of the Away3D TypeScript: Primitives – Plane. All the new or changed code will be highlighted in the full code block below.

WireframePlane.ts

Line 5 renames the class to WireframePlane.

Line 17 declares a variable named _objectWireframe of type WireframePlane.

Line 60 instantiates a new object referenced by the variable _objectWireframe. It was initialized with 300, 300, 5, 5, 0xFFFFFF, 1: which we’ll discuss more later.

Line 61 adds the object to the scene.

Lines 76-77 adds a spin to our object on every frame of animation.

Line 102 changes the called class name to WireframePlane.

That’s it, our object is in the scene.

However, we glazed over the initialization process, let’s take a closer look at the object’s constructor.

Constructor

The constructor looks as follows:

The Constructor’s Parameters:

  • width:Number (default = 100) — The width of the plane.
  • height:Number (default = 100) — The height of the plane.
  • segmentsW:uint (default = 10) — The number of segments that make up the plane along the X-axis.
  • segmentsH:uint (default = 10) — The number of segments that make up the plane along the Y or Z-axis.
  • color:uint (default = 0xFFFFFF) — The color of the wireframe lines
  • thickness:Number (default = 1) — The thickness of the wireframe lines
  • orientation:String (default = yz) — The orientaion in which the plane lies.

So in our initialization we stated:

Which created a Plane:

  • With a width of 300 units.
  • With a height of 3000 units.
  • 5 segments along the width.
  • 5 segments along the height.
  • colored white (0xFFFFFF).
  • With a line thickness of 1 units.
  • We left the orientation at default (YZ).

In Closing

Adding a basic primitive is relatively easy. Just understanding the constructor and what the parameters are, is the hardest part. You can look at the official documentation here.
