: TEXTURE : Bounding:ObjectShortcut
: NoneThis command defines a surface as a bounding object for texturing other objects. It works in conjunction with the command TEXTUREÞBounding:Assign which actually applies the bounding object to the surfaces.
A bounding surface is an ‘invisible’ surface that will not show in the ExTrace picture. It is used only to project the texture onto the actual surfaces. Likewise, a bounding surface will automatically be made passive, so as not to be displayed with the actual objects.
This command asks for the texturing parameters in a similar way to the command TEXTUREÞArea:Create New. However, those parameters that do not have significance with bounding objects are not requested.
In particular, adaptive mapping is not available with bounding objects. Therefore, the bounding surface should be relatively simple, in particular, the points in the projection and cross-section curves should be as evenly spaced as possible. Simple primitive surfaces or those extruded or rotated from Bézier curves usually make the best bounding surfaces.
Additionally, the command asks for a name for the bounding object. This is required to assign the correct bounding object to the right surfaces. If you give a name that is already in use, the program complains and asks for a different name.
