Part 5 - Apply Warp Vectors.
Change the main mode from "Region" to "Warp". Note that the "Define/Modify Warp Vectors" mode is set to "Add XY Vector". Click on the "Geometry..." button to add vectors. In the "XY Vector Geometry" dialog, enter 4 vectors (in Data Coordinates) as shown (at least 4 vectors and/or stationary points are always required for XY warping):
Click on "Ok". The new warp vectors are drawn on the sculpture grid in orange. The bottom two vectors do not have any length (drawn as a small "X") - they will function as stationary points in the warping. Vectors can also be added by clicking and dragging the left mouse button on the sculpture grid. Click on the "Apply XY Warp" button. Note how the upper two warp vectors have essentially caused the upper portion of the sculpture grid to be squashed together. Also note that the warp has been applied to the region perimeter.
Change the warp vector mode to "Add Z Vector". The "Z Height" widget will become active. Enter a Z Height value of 1. Click the left mouse button on the sculpture grid in about 4 or 5 scattered locations. Each click will place a Z vector with a height value of 1. Change the Z Height to 2. Click on a few scattered locations to place more Z vectors. Change the Z Height to 0. Click to create a few more stationary points. At least 3 Z vectors and/or stationary points are required for Z warping. Click on "Apply Z Warp". All the Z vectors and stationary points (but not the XY vectors) are triangulated, and the triangulated surface heights are added to the current sculpture grid heights.
