CST2013: View Options - Illumination

View: Options View Options - Illumination

OpenGL is used for 3D plots. To make a scene appear to be 3D you have to define virtual light sources. One direct light source is virtually positioned in front of your screen. Additionally there is ambient light, which seems to come from all directions, thus it lights up all parts of your plot.

In this dialog box you can vary the amount of ambient light.

You may also set the surface reflectivity here. This will influence how much direct light will be directly reflected by the plot’s objects.
