Use gravity for Z position

[Miha Nahtigal]

My Addon creates API_Element (GDL object) on user specified coordinates acquired with APIIo_GetPointID. X and Y coordinates are ok, Z coordinate is always zero.

I would like to use gravity when picking a point on eg Mesh so Z coordinate gets populated too.

Is this possible?

Talking to myself a bit more...

I could use TDGetHeightAtPoint() which will "Calculate the height of a triangulated mesh at a given location."

Unfortunately one of the parameters is a list of triangles. Browsing through mesh type and its memo, I do not think I can extract them from specified existing mesh.

To go a bit further... there is also a TDTriangulate() function. Wouldn't be a bit overkill using it on already defined (and triangulated) mesh?

I don't know if there is a shortcut to achieving this. You could get the 3D body of the mesh from ModelAccess or the older 3D Manager (ACAPI_Element_Get3DInfo etc). You could then determine which face lies directly under the point of interest and the z level on the plane at that point.

I've decided to change my object creation concept.

Switched from APIelement creation to new element event observer and let user use default gravity functionality of AC. API magic is fired afterwards.
