RigidBodypt on the surface of this Wrappable such
that the line segment (pa,pt) is both tangent to the surface and as near
as possible to the line defined by the two points pa and p1.
To assist with the computation, pKcheck[kmax]t can be assumed to lie
fairly close to p1, and its projection onto the line can be
assumed to lie between p1 and another point p0 defined by
p0 = (1-lam0) pa + lam0 p1where
lam0 is a parameter between 0 and 1.surfaceTangent in interface WrappablesurfaceTangent in class RigidBodypr - returns the tangent pointpa - first point of the linep1 - second point of the linelam0 - parameter defining point p0 as defined abovesideNrm - a normalized vector perpendicular to the plane defined by

RigidBodyp0 into this
Wrappable, along with the normal nrm that points from
p0 to its nearest point on the surface. The distance should
be negative if the point is inside the wrappable, and positive otherwise.
If the point is outside and further than some minimum distance,
then the method should return the constant Wrappable.OUTSIDE.
If possible, the method should also compute the derivative of the
normal with respect to changes in p0, and return this in
dnrm. If this is not possible, dnrm should be
set to 0.

TransformableGeometrygtr to transform its individual attributes. The
context argument supplies information about what other
components are currently being transformed, and also allows the
requesting of update actions to be performed after all transform called
have completed. The context is also the usual entity that calls
this method, from within its TransformGeometryContext.apply(maspack.geometry.GeometryTransformer, int)
method. The argument flags provides flags to specify
various conditions associated with the the transformation.
At present, the available flags are TransformableGeometry.TG_SIMULATING and
TransformableGeometry.TG_ARTICULATED.
This method is not usually called directly by applications.
Instead, it is typically called from within the
TransformGeometryContext.apply(maspack.geometry.GeometryTransformer, int) method of the context,
which takes care of the various operations needed for a
complete transform operation, including calling
TransformableGeometry.addTransformableDependencies(artisynth.core.modelbase.TransformGeometryContext, int) to collect other
components that should be transformed, calling
TransformableGeometry.transformGeometry(maspack.matrix.AffineTransform3dBase) for each component, notifying
component parents that the geometry has changed, and calling
any requested TransformGeometryActions. More details
are given in the documentation for
TransformGeometryContext.apply(maspack.geometry.GeometryTransformer, int).
TransformGeometryContext provides a number of
static convenience transform methods
which take care of building the context and calling
apply() for a specified set of components.
This method should not
generally call transformGeometry() for its descendant
components. Instead, descendants needing transformation should be
specified by adding them to the context in the method TransformableGeometry.addTransformableDependencies(artisynth.core.modelbase.TransformGeometryContext, int).
