|
// CLASS DESCRIPTION (M3dView)
|
|
//
|
|
// M3dView provides methods for working with 3D model views. 3D views are
|
|
// based on OpenGL drawing areas.
|
|
//
|
|
// Maya can operate in two different color modes, RGBA and color index. Color
|
|
// index mode is used to increase performance when shading is not required.
|
|
// Drawing in color index mode is more complicated, but this class provides
|
|
// methods to simplify color selection.
|
|
//
|
|
// Maya has four color tables that can be used in RGBA, and that must be used
|
|
// in color index mode. These four color tables represent four sets of bit
|
|
// planes that are independent of each other. So, for example, it is possible
|
|
// to clear all active objects from the display and redraw them without
|
|
// redrawing the dormant and templated objects.
|
|
//
|
|
// The extra performance of color index mode comes at the cost of a
|
|
// limited number of colors. If this restriction causes difficulty, then
|
|
// it is possible for the user to force all displays into RGBA mode
|
|
// where any color may be used.
|
|
//
|
|
// When an object is affected by another in the scene, it is drawn in a
|
|
// magenta colour by default. This is denoted in the DisplayStatus enum by
|
|
// kActiveAffected. These objects are drawn in the active planes even though
|
|
// they are dormant for performance reasons.
|
|
//
