FIGURE 13.39
Two patches of different resolutions have been combined using the Bind and Weld buttons.
After you assign colors, you can recall vertices with the same color by selecting a color (or illumination
color) in the Select Vertices By section and clicking the Select button. The RGB values match all colors
within the Range defined by these values. For example, if the RGB Range values are all set to 255, then
every vertex is selected.
Editing handles
The Handle subobject mode gives you direct access to the vertex handles without the vertices or edges get-
ting in the way. You can still work with handles in Vertex subobject mode, but the Handle subobject mode
is more convenient and you don’t need to worry about accidentally moving the vertex in the process.
When the Handle subobject mode is enabled, all vertex handles for the entire patch object are visible.
Multiple handles can be selected and transformed at the same time. The Copy and Paste Tangent options
are available for this mode also.
Editing edges
Edges are the lines that run between two vertices. You can select multiple edges by holding down the Ctrl
key while clicking the edges or by holding down the Alt key to remove selected edges from the current
selection set.
