1.5.1 Warp Vector Definition/Modification.

Warp Vectors are used to stretch the sculpted surface - either in the XY plane, or in the Z direction. The Z warp capability can be used to triangulate and "grid" scattered XYZ points. Warp vectors are displayed on the sculpture grid as orange arrows (XY vectors), orange "X" markers (stationary points), or orange "+" markers with a Z height notation (Z vectors). At least four XY vectors and/or stationary points are required for XY warping. At least three Z vectors and/or stationary points are required for Z warping. Z vectors have no effect on XY warping, and XY vectors have no effect on Z warping.

Definition/Modification modes :

"Add XY Vector" : Click and drag the left mouse button on the sculpture grid to draw an arrow (XY vector). Click and release (without moving the mouse) to enter a stationary point.

"Add Z Vector" : Click the left mouse button on the sculpture grid to place a Z vector. The height of the placed Z vector is taken from the "Z Height" setting. If the Z Height is set to 0, then the clicked point is considered a stationary point (no Z height notation is displayed above the "X").

"Move/Stretch" : Click and drag the left mouse button near an XY vector to move the closest end of the vector. Click the left mouse button near a Z vector to update it with a new Z height from the "Z Height" field (this is, essentially, stretching the vector in the Z direction). Click and drag the right mouse button near an XY vector to translate it (both ends will move so that the length and direction of the vector do not change). Click and drag the right mouse button near a Z vector to translate it in the XY plane. Click either button near a stationary point to translate it in the XY plane.

"Delete Vector" : Click the left mouse button on the sculpture grid and the nearest vector or stationary point is deleted.

"Geometry..." : In "Add XY Vector" mode, this button will bring up the "XY Vector Geometry" dialog. This dialog has two fields. The "Coordinate System" setting specifies which coordinate system to use - Grid Units or Data Units. The "Vector(s)" field is for typing in the desired XY vectors, one vector per line of the form X1,Y1,X2,Y2.

In "Add Z Vector" mode, clicking the "Geometry..." button will bring up the "Z Vector Geometry" dialog. This dialog has two fields. The "Coordinate System" setting specifies which coordinate system to use - Grid Units or Data Units. The "Vector(s)" field is for typing in the desired Z vectors, one vector per line of the form X,Y,dZ.
