Returns:

gvector

Description:
|
This extension returns the unitized
gvector that points toward the right side of the view. This corresponds to the
x-axis of the view coordinate system. The gvectors returned from the operations
view:out,
view:right, and
view:up form a right-handed orthonormal triple. Each is the cross-product of the other two. The
view:out vector is always perpendicular to the screen. After the model has been reoriented, this command determines the
x-axis relationship to the model.
|
|
|
The argument
view specifies the specific view to get the handle from. If not specified, the active view is used.
|
|
|
Limitations:
|
This extension is available on all platforms, but produces results only on NT using OpenGL.
