// Class Description:
|
|
// Visualization attributes are a set of information associated with the
|
|
// visualizable objects. This information is necessary only for
|
|
// visualization, and is not included in geometrical information such
|
|
// as shapes, position, and orientation.
|
|
// A typical example of a visualization attribute is "colour".
|
|
// For example, in visualizing a box, the Visualization Manager must know
|
|
// its colour. If an object to be visualized has not been assigned a set of
|
|
// visualization attributes, then a proper default set is used
|
|
// automatically. A set of visualization attributes is held by an
|
|
// instance of class G4VisAttributes defined in the graphics_reps
|
|
// category. The followings are commonly-used attributes:
|
|
// - visibility
|
|
// - visibility of daughters
|
|
// - force style
|
|
// - force auxiliary edge visibility
|
|
// - force line segments per circle
|
|
// - colour
|
|
