Parameters

mesh

Type: Rhino.GeometryMesh
mesh to test

pickStyle

Type: Rhino.Input.CustomPickContextMeshPickStyle
mode used for pick test

hitPoint

Type: Rhino.GeometryPoint3d
location returned here for point picks

hitSurfaceUV

Type: Rhino.GeometryPoint2d
If the mesh has surface parameters, set to the surface parameters of the hit point

hitTextureCoordinate

Type: Rhino.GeometryPoint2d
If the mesh has texture coordinates, set to the texture coordinate of the hit point. Note that the texture coodinates can be set in many different ways and this information is useless unless you know how the texture coordinates are set on this particular mesh.

depth

Type: SystemDouble
depth returned here for point picks LARGER values are NEARER to the camera. SMALLER values are FARTHER from the camera.

distance

Type: SystemDouble
planar distance returned here for point picks. SMALLER values are CLOSER to the pick point

hitFlag

Type: Rhino.Input.CustomPickContextMeshHitFlag
For point picks, How to interpret the hitIndex (vertex hit, edge hit, or face hit)

hitIndex

Type: SystemInt32
index of vertex/edge/face that was hit. Use hitFlag to determine what this index corresponds to
