Applying Cylindrical Ramps
Selection Tools
 The Cylindrical Ramp Tool. Keyboard Shortcut: Ctrl+C
In a Cylindrical Ramp, depth values vary from one selected depth value in the center to the second selected depth value on the outside edges. Use Cylindrical Ramps for curved surfaces like coffee cups. [Example]
Like all Depth Data Ramps, the Cylindrical Ramp has to be applied to existing data.
-
Paint Depth Data points of any value over the part of the image you want to apply the ramp to
-
Use one of the Selection tools to select this part of the image.
Tip: For irregular shapes use the  Freehand selection tool.
-
Select the Cylindrical Ramp Tool.
-
Select the two depth values (Depth1 (red, left) and Depth2 (green, right)) to use for the middle and edges of this ramp.
Tip: A % symbol above the Depth Picker indicates that the Percent scale is selected. No % symbol means the Value scale is selected.
Tip: To quickly sample two depth values on the screen, press and hold the Alt key to select the  Eyedropper tool, then click and drag from one value to the next. Release the Alt key.
-
Click and drag the mouse in a line across the selection. For example, if you were Depth Mapping a tree trunk you would drag the line as if you were cutting the tree down.
Tip: You can get different effects by varying the starting point, the angle and the length of the line.
Tip: If you do not like the effect you can simply draw another line immediately.
