13 - The Lights Inspector

Edit lighting schemes based on viewpoints. Interactive settings and immediate results in the Preview window. Using the appropriate and correctly adjusted light model promotes the work carried out on the materials. Light groups may be attached to 1 or more viewpoints. The lights are characterized by an illumination limit and a maximum illumination area.

Lights List: for handling lights on the list shown.

Lighting

1. Select projection type

   determines the lighting projection (falloff) from 9 predefined types

2. On/Off
3. Color:

Double click to modify the source color.

4. Source power

Values from 1 to 1,000,000. Move the slider to change the power or enter a value.

5. Attenuation Distance

Calculates the attenuation distance for the lighting power.

Between the attenuation distance and source, the lighting power remains constant and at maximum.

The distance beyond distance A corresponds to the gradual diminishing of lighting power at 1/d². When the attenuation value equals 0, the light diminishes at 1/ d² beginning at the light source.

Enter the distance in the numerical field (current unit).

NB: in this area, the illumination principle is based on reality.The closer an object is placed to the light source, the more illuminated it appears.

6. Change the Lighting Angle:

By sliding from 10 to 360° or by typing in a numerical value.

Example: A value of 360° provides an omnidirectional light.

7. Shadow projection

Activate/Deactivate shadow projection: Click on the box to check it.

8. Shadow type

Sharpness slider on the edge of the illuminated area. Values from 0 (diffuse area between the shadow area and the illuminated area) to 100 (straight limit). Accepts a numerical value.

9. Luminous halo:

Activate/Deactivate: Click on the box to check it.

Choose effect: Click on one of the thumbnails:

Halo Power: Move the Power slider or type in a value between 10 and 200%.

10. X, Y, Z Coordinates: of the position of the light source and its target.

Clicking on locks them and clicking on unlocks them.

Activated target: choose between target on a fixed vertex or on an object defined as target.

NB: editing the scene information such as the infinite ground, movement of the origin, redimensioning of the model and the coordinates may be accessed via the Window menu.
