| How might I find the nearest vertex to a picked location. I have a large mesh, I pick a point on it. I want to remove the nearest vertex on that mes to the picked location on it. How? Thanks in advance. |

| Just a quick thought ... someone else could prob. elaborate a little better. #1) use camerapick() to get the entity at point x,y #2) use pickedtriangle() to get the trianlge you picked from the entity #3) use pickedX,PickedY,PickedZ to get the world cord. of the pick #4) use trianglevertex() and grab the 3 vertices of the trianle #5) transform the vertex cordinates to world cords. #6) do a distance comparison of the pickedX,Y,Z cordinates to the transformed vertices #7) the closest one wins ! thats your vertex |
