MTSInstance2d

An MTSInstance2D object is used to represent a Viewpoint text object. The text may be attached to an Atmosphere
object in 3D, or may be placed in a fi xed position in the display window. (See the instructions for "dstPin" below.)
The geometry object must be fi rst defi ned in an XML description fi le. (It is defi ned using a <LayerData> tag of a
Viewpoint instance. The instance must also contain a geometry tag describing the type of Viewpoint geometry.) Once
loaded nearly all aspects of the text object may be modifi ed in real time.
It is important to note that the attribute AlwaysVisible="1" must be present in the MTX description fi le in order for
the text to be displayed in Atmosphere. (Text created with the "Viewpoint Scene Builder" application has this attribute
off (0) by default, but can be set to on (1) using the command "Show Hot Spot text" in the "Hot Spot" menu.)
