Common Properties for All 3D Primitives

Once you add a primitive object to the 3D space, you can use its properties to create the look you need. You can also move, rotate, and scale the shape and apply images, textures, and colors to the surface of the shape. For more information, refer to Object Properties.

 

Common properties for primitives are height, width, side, segment, slice angle, cap, radius, material, tile, center, name, and transformation properties.

Center

Within the Appearance properties for a 3D Model, users can make Center settings. This represents the center of the object. This location is used as the pivot point for rotation and scaling. Use the pulldown menu to select from Center Left, Center Bottom, Center Back, Center Right, Center Top, or Center Front. When the Center property is expanded, you can also see the individual X, Y and Z coordinates and how any of the pulldown menu selections affect each coordinate. You can then fine-tune any pre-filled coordinate setting within its text entry field.

Height, Width, Side, and Segment Properties

Primitive shapes have many properties which you can control. Height, width, and the number of sides are the most obvious properties of any shape, but in GraphWorX64 3D you can also control the number of segments that make up the height, width, and sides of an object. The number of segments can determine an object’s shape, such as whether it has discernible sides or is smooth or rounded in appearance. While more segments give you a smoother surface, fewer segments give you faster rendering.

 

In GraphWorX64 3D, you can manipulate the segments of a primitive. The 3D viewport has selection modes that can let you select an entire object or a facet or segment of an object, for a more refined (although advanced) means for manipulating objects. For more information, refer to Selection Mode Section of the 3D Home Ribbon.

 

Important: Adding segments adds points and surfaces to the object. And adding points and surfaces adds memory consumption. If you raise the number of surfaces on an object from 60 to 500, the object consumes more memory. It is important to understand this, especially if you are animating in real-time because the power needed to animate it increases with the quality of the graphics. Higher quality means that more power is required.

Slice Angle Properties

For many primitive shapes you can define a Slice Angle property to create a wedge shape or to create a shape with a wedge taken from it. For the Slice Angle property, you define the degree of angle you want to cut out of the shape. The range you can enter is from 0 (no angle is cut from the shape) to 360 (a complete removal of the entire shape).

Cap Properties

The CapTop and CapBottom properties determine whether a shape is closed off at the top or bottom. (Other properties such as CapStart and CapEnd create the same effect.) If the cap property is set to true, the shape appears to be solid or capped; set to false, the shape appears to be empty or has no cap. Typically, a cap set to false reveals the inside of the shape; since by default the inside is transparent, an uncapped shape will reveal invisible sides. You can give a shape an inside color or texture by using the shape’s BackMaterial property.

Radius Properties

Some shapes have a Radius property. The radius defines the width of a round or spherical shape. But some shapes have two Radius properties, usually called Radius1 and Radius2.

Note: Where there are two Radius properties, the larger value defines the larger radius, and the smaller value defines the smaller radius.

Material Properties

Each primitive shape has the following material properties:

Tile Properties

Each primitive shape also has properties TileMode and CustomTile properties that are not used. Changing these properties by typing new values on the Properties tab does not affect the texture in the display. To change these properties, you must click the Material property’s ellipsis button to open the color dialog box, click the Diffuse Color icon to launch the color swatch dialog box, then go to the Image tab and set the properties there. For more information on setting these properties, see Image Tab.

The Center Property

Use the Center property to offset the object’s pivot point for rotation and movement. The center is the pivot point. For example, if you are adding a Rotation dynamic and want the object to rotate around an external pivot point, enter the offset pivot point as the Center property.

The Name Property

Use the Name property to label the object so that you recognize it in the Explorer. You can also change an object's name in the Explorer itself.

Transformation Properties

Each primitive has two Transformation sections in its Properties tab, which you can use instead of the manipulators in the Manipulator Section of the 3D Home Ribbon:

These properties are useful for moving, rotating, or resizing (scaling) object(s) or sub-elements in a 3D view.
