closestPointOnMesh

Go to: Attributes.

This node returns the closest point of an (x,y,z) point (attribute "inPosition") to a mesh (given by the attribute "inputMesh"). You can query the closest (x,y,z) point (attribute "position") or you can query the closest mesh (u,v) point (given by attributes "parameterU" and "parameterV").

Long name (short name)	Type	Default	Flags
inputMatrix (ix)	matrix	NULL
Input transformation matrix of the mesh, which allows the closest point to be calculated in world space coords. This defaults to the identity matrix, so if it's not set to something else, the closest point will be calculated in the mesh's local space.
inMesh (im)	mesh	NULL
The input mesh for the info
inPosition (ip)	double3	0.0, 0.0, 0.0
Input reference point
inPositionX (ipx) distance (double) 0.0cm Input X value of reference position
inPositionY (ipy) distance (double) 0.0cm Input Y value of reference position
inPositionZ (ipz) distance (double) 0.0cm Input Z value of reference position
result (r)	compound	n/a
All results - container holding closest point, its normal, u and v parameter values and closest face index.
position (p) double3 0.0, 0.0, 0.0 The closest (x,y,z) point (in result compound) positionX (px) distance (double) 0.0cm Computed X value of closest point positionY (py) distance (double) 0.0cm Computed Y value of closest point positionZ (pz) distance (double) 0.0cm Computed Z value of closest point
parameterU (u) double 0.0 The U parameter value on the mesh at the closest point
parameterV (v) double 0.0 The V parameter value on the mesh at the closest point
normal (n) double3 0.0, 0.0, 0.0 The normal of the point (in result compound) normalX (nx) distance (double) 0.0cm X normal of closest point normalY (ny) distance (double) 0.0cm Y normal of closest point normalZ (nz) distance (double) 0.0cm Z normal of closest point
closestFaceIndex (f) integer -1 Index of the face on which the closest point lies.
closestVertexIndex (vt) integer -1 Index of the vertex closest to position on faceIndex.
