FastPointCloud.ColorArray Property
The size of the array determines how the colors are applied to the entity:
1 byte per vertex is applied as a modulation factor (0-255) to the Entity.Color of the entity. This requires the use of shaders so the
graphics acceleration must be turned on, Environment.UseShaders must be true (Winforms Eyeshot control only) and the DisplayMode must be displayType.Rendered
3 bytes per vertex are applied as RGB colors
4 bytes per vertex are applied as RGBA colors (in order for the alpha transparency to work, the entity must also have a
Entity.Color with alpha < 255 and Environment.AccurateTransparency must be set to false).
