2.2.4 Color, Lighting.

"Resources / Color..." : This will bring up the "Define Colors" dialog. Colors can be used for all types of entities and lights. Each color has a user-specified name, and is defined by the intensity of it's red, green, and blue components. Each component of a color can be set using the associated slider bar. The color bar shows the current RGB mix. Possible settings range from 0 (0% intensity) to 255 (100% intensity). To define a new color, set the red, green, and blue intensities. Type in a new name (a name that is not already in the "Current Colors" list). Then click on "Create". The new color will then appear in the list (along with the nine predefined system colors). To modify an existing color, click on the desired color in the list. Then modify it's intensities and click on "Apply". (The name of an existing color can not be changed). Colors (except for the predefined system colors) can be deleted via the main "File / Delete => Colors..." menu.


"Resources / Lighting..." : This will bring up the "Define Lights" dialog. All existing lights contribute to the illumination of the CAD model. Each light has a user-specified name. There are three basic types of lights - "Ambient" (fully diffused in all directions), "Position" (pin-point source with diverging rays), and "Direction" (parallel rays). In the "Position / Direction" field, enter the location/direction of the light as a 3-element vector (separate the numbers with spaces or commas). The Position/Direction coordinates are measured relative to the computer screen (the lights do not rotate when a view is rotated). The Position/Direction setting does not apply to "Ambient" lights. The "Intensity %" setting controls the brightness of the light. The "Color" setting controls the color of the light. Light colors should normally be bright (if desired, the intensity can be dimmed via the "Intensity %" setting).

To define a new light, set the light parameters and type in a new name (a name that is not already in the "Current Lights" list). Then click on "Create". The new light will then appear in the list (along with the two predefined default lights). To modify an existing light, click on the desired light in the list. Then modify it's parameters and click on "Apply". (The name of an existing light can not be changed). Lights (including the predefined default lights) can be deleted via the main "File / Delete => Lights..." menu.
