// Class : TextureTransition
|
|
// Description : This controls the assignment of the primary texture
|
|
// to a piece of geometry. If there is no
|
|
// TextureTransition or the transition is off, the
|
|
// geometry is rendered untextured; if there is an 'on'
|
|
// TextureTransition affecting a piece of geometry it
|
|
// will be rendered with the indicated texture.
|
|
//
|
|
// At one time this was a MultiTransition because we
|
|
// were thinking of using this interface to support
|
|
// multitexturing. But on reflection that is a flawed
|
|
// idea because MultiTransitions don't support any
|
|
// ordering, and we don't yet have an interface for
|
|
// specifying multiple layers of UV coordinates anyway.
|
|
// Until this is fully worked out, this will be a simple
|
|
// OnOffTransition: either there is a texture or there
|
|
// isn't.
