Description Deforms a base surface according to a specific deform surface definition.
Syntax SetSurfDeform n, bEnable, nDefNode, dScale, bInBaseCoordSys
Parameters n As Long Node number of base surface.
bEnable As Boolean Flag to turn deformation on or off.
nDefNode As Long Node number of surface used as deformation.
dScale As Double Scales the amplitude of the deform surface.
bInBaseCoordSys As Boolean Flag indicating whether deformation is applied in the coordinate system of the base surface (True) or in the global coodinate system (False).
Remarks Deforms a base surface according to a specific deform surface definition.
Mathematically, deformations are implemented by shifting the zeros of the base surface's function. Let fb(x,y,z) = 0 define the base surface and fd(x,y,z) = 0 define the deforming surface. Further, assume that the deforming surface is defined as a height map along z (e.g, fd(x,y,z) = z - gd(x,y) ). This is the "sagability" assumption. FRED doesn't enforce this, but it will generally print a warning to the output window when it detects a deformer that's not "sagable". When the deformation is applied to the base surface, the resulting combined surface is defined by (ignoring coordinate system transformations):
