Analyzing Using Single Light Band Mapping

1. Click the Single Light Band Mapping Analysis icon:

The Single Light Band Mapping dialog box appears.

The single light band mapping analysis options are displayed:

• Options:

  • Viewpoint Dependent Mode: fixes the direction relative to the screen and the geometry can rotate independently to that direction

  • Global Mode: performs the analysis on all the surfaces of the active part, otherwise only the selected surfaces are analyzed.

  • No Highlight Representations: removes the highlight representation from selected elements.

• Texture:

  • Thickness: sets the texture thickness value.

  • Sharpness: sets the texture sharpness value.

  • Brilliance: sets the texture brilliance value.

  • Diffusion: sets the texture diffusion value.

• Color:

  • H: sets the hue color value.

  • S: sets the saturation color value.

  • Max L: sets the maximal luminance color value.

  • Min L: sets the minimal luminance color value.

The single light band is displayed on the surfaces and the single light band manipulator appears.

Manipulation

2. Move the manipulator to change the light direction.

According to the selected arrow of the manipulator you can rotate it around two axes:

If you select all the manipulator you can rotate it freely:

• The red arrow of the manipulator indicates the center of the rotation.

• When you click it the manipulator is moved to the opposite location according to the center of the rotation. This action only changes the manipulator location, not the light orientation.

3. Right-click the manipulator to display contextual menu items.

The following commands and options are available:

• Light edition:

  • Edit Light Direction: displays the Direction dialog box,
    

    • The Direction frame allows you to define the absolute values for the direction.

    • The Step-by-Step Rotation frame allows you to define the angle increment, the rotation axis and its direction.

    • The Quick Orientation frame allows you to orientate the direction according to the main axes or the Compass direction.

  • Save Light Direction: displays the Save Direction dialog box,
    

    • Click Save to save the current direction in the list.

    • Click a direction in the list to position the manipulator.

• Lock Manipulator: this option locks the manipulator selected axis of rotation.

• Rotation options:

  • Rotation Free: allows you to rotate freely the light direction.

  • Rotation around X: allows you to rotate the light direction around the X axis only. In this case, only the red arrow of the manipulator indicating the center of the rotation is displayed.

  • Rotation around Y: allows you to rotate the light direction around the Y axis only. In this case, only the red arrow of the manipulator indicating the center of the rotation is displayed.

  • Rotation around Z: allows you to rotate the light direction around the Z axis only. In this case, only the red arrow of the manipulator indicating the center of the rotation is displayed.
