Then I draw another same cuboid at different place. I turnd them to TriObject, then I used GetMesh() to turn them to mesh and get the points' coordinates . To my surprise, the coordinate of their points are totally same. Why？Is it because I turned them to mesh? How can I get the correct coordinate relative to (0,0,0)?</P> <P>&nbsp;</P> <P>The photos below are my objects in 3dmax and a part of the code. The result is that the two sets of coordinates are exactly the same.Why?</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="QQ图片20190128181211.png" style="width: 999px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/596129i6A82862AD204EAAD/image-size/large?v=v2&amp;px=999" role="button" title="QQ图片20190128181211.png" alt="QQ图片20190128181211.png" /></span></P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="QQ图片20190128181809.png" style="width: 736px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/596135i139FB8168E8BF371/image-size/large?v=v2&amp;px=999" role="button" title="QQ图片20190128181809.png" alt="QQ图片20190128181809.png" /></span></P> Mon, 28 Jan 2019 10:19:00 GMT https://forums.autodesk.com/t5/3ds-max-programming-forum/how-can-i-get-the-points-coordinate-of-mesh-objects-correctly/m-p/8553823#M8986 Anonymous 2019-01-28T10:19:00Z https://forums.autodesk.com/t5/3ds-max-programming-forum/how-can-i-get-the-points-coordinate-of-mesh-objects-correctly/m-p/8554424#M8987 <P>Point coordinate for a mesh is returned in an object's <EM>local</EM> transform space.<BR />In your case, coordinates will be the same.<BR />If you want to get a point coordinate in <EM>world</EM> space you should either multiply point position by an object's global transform matrix or 'freeze' object's transform.</P> Mon, 28 Jan 2019 14:47:16 GMT https://forums.autodesk.com/t5/3ds-max-programming-forum/how-can-i-get-the-points-coordinate-of-mesh-objects-correctly/m-p/8554424#M8987 Anonymous 2019-01-28T14:47:16Z
