PK_proj_max_dist_t

typedef int PK_proj_max_dist_t;

Used in:

PK_CURVE_project_o_t

This datatype specifies whether to limit projections to those where the
projection lies within a specified projection distance of the curve that is
projected.

It has values:

    PK_proj_max_dist_no_c      Do not consider the projection distance
                               between the projection of the curve and
                               the curve itself.

    PK_proj_max_dist_whole_c   Only produce projections that lie wholly
                               within the specified 'max_dist' of their
                               originating curve.  A projection of an
                               originating curve onto a particular face
                               is not produced if the distance of the
                               projection of any point of the originator
                               is further than this.
