Component Properties

The Component Properties window displays and allows you to update many properties of Scene Components.

Object Attributes

These are read-only attributes of an object, including the number of faces and points that make up the object, as well as the size of the object. This is only displayed for objects.

Frame Position

The position within the scene of the component's frame.

This will only be displayed for scene components that have position. For example, the ambient and directional lights do not have positions.

Frame Rotational Velocity

The rotational velocity of the component's frame. The axis of rotation is expressed as a unit vector. So if you want an object to rotate around the X axis, you would set the X axis to 1 and the remainder to 0. If you want an object to rotate around both the X and Y axes, you would set X and Y to 1 and Z to 0, and 3D Canvas will calculate an appropriate unit vector.

This will only be displayed for scene components that have an orientation. For example, many lights do not have an orientation.

General Light Attributes

All lights have color, an attenuation type and an attenuation factor.

Color can ranges from black (off) to white (maximum intensity).

The attenuation type and factor specify how the intensity of the light changes with distance.

Spotlight Attributes

Spotlights have additional properties including the Range, Umbra angle and Penumbra angle.

Range is the distance from the spotlight that is lit by the spotlight and is in model units.

Umbra and Penumbra are specified in radians (3.14 = 180 degrees).
