[Oldnick]

i have sphere on scene and mouse coords (klick on sphere).... how calculate 3d coordinates? :roll:

[BYTE-Smasher]

Dim Pick As TVCollisionResult
Set Pick = TVScene.MousePicking(CurrentMouseX, CurrentMouseY, 0, TV_TESTINGTYPE)
If Pick.IsCollision = True Then
Scene.DrawText "Impact " & Pick.GetImpactPoint.X & " " & Pick.GetImpactPoint.Y & " " & Pick.GetImpactPoint.Z, 20, 30
End If
