Tools > Color is a set of functions for the handling of color on point and polygon objects.
Color can stored in an object in several ways:
Vertex Color - A polygon object with vertex color stores a color attribute in each vertex. The resolution and quality of a colored surface is determined by the number and position of vertexes.
Texture Color - A polygon object with texture-mapped color has a high-resolution image stored in the same file, and uses industry-standard UV Coordinates to map that image to the polygon mesh when it is rendered on the screen. Thus, the polygon object appears to have a high-resolution color image. The resolution of the color can be higher than the spacing of vertexes on the mesh.
To discover whether a colored object has vertex color or texture color, make it active in the Model Manager and click the Primitives Tab on the Manager Panel. The following primitives are relevant to an object's color:
Auto Texture - superimposes a psychedelic pattern on the object, which overlays vertex color if vertex color is present. This is a "visual effect", not real color.
Texture Color (grayed-out if the object does not have texture color) - turns texture color on and off.
Vertex Color (disappears if the object does not have vertex color) - turns vertex color on and off.
Object Color (no effect if Texture Color or Vertex Color is on) - turns on the color that may be set by View > Objects > Edit Object Color, one of sixteen color choices that are visible in Geomagic applications only. This is a "visual effect", not real color, and the functions at Tools > Color have nothing to do with Object Color.
All functions on this menu deal with texture color. Some deal with texture color but not vertex color. (None deal with object color.)
Adjust Colors (applicable to a point object that has vertex color, and to a polygon object that has vertex color or texture color) is a set of functions that modify the color of all points or pixels of the active point or polygon object. This is like adjusting the brightness on your television.
Edit Colors (applicable to a point object that has vertex color, and to a polygon object that has vertex color or texture color) is a set of functions that change the color of selected areas of point or polygon objects.
Remove Vertex Color (applicable to a point or polygon object that has vertex color, not texture color) permanently removes all vertex color and shades of gray from a point or polygon object.
Generate Texture - creates a texture map on the active polygon object.
Manage Texture (applicable to a polygon object with texture color) offers the ability to "detach" the mapped image from the polygon object so that it can be edited with external software and then re-attached.
Remove Texture (only for objects with texture-mapped color) - removes texture color from a polygon object.
