If the axis-aligned ray from the point does not intersect the surface, the original point is returned and -1 is returned in the other output parameters.

[in]iaxisint Axis direction to project point along (X_DIR, Y_DIR, or Z_DIR)
[in]ptInput 3D coordinate point

◆ AxisProjPnt01Guess()

const int & surf_indx,
const int & iaxis,
const vec3d & pt,
const double & u0,
const double & w0,
double & u_out,
double & w_out )
extern

Project an input 3D coordinate point onto a surface along a specified axis given an initial guess of surface parameter. If the axis-aligned ray from the point intersects the surface multiple times, the nearest intersection is returned. If the axis-aligned ray from the point does not intersect the surface, the original point is returned and -1 is returned in the other output parameters. The surface parameter guess should allow this call to be faster than calling AxisProjPnt01 without a guess.
