Bea Greaves Posted June 14, 2002 Share Posted June 14, 2002 I have a 3D polygon where each vertex is at a different height. When I render using Final Quality Render in an isometric view the perimeter line is correctly set but the fill is offset irregularly. When I render using Quick Render it works fine. But sometimes objects underneath the polygon show through when they're not meant to and sometimes the polygon shows through objects that are meant to be on top! Any suggestions please?

Guest Posted June 17, 2002 Share Posted June 17, 2002 What version of VW are you using ? Are you on a mac or pc ? Do you notice this instance happening in other drawings, or just this one drawing? Quote Link to comment
Bea Greaves Posted June 21, 2002 Author Share Posted June 21, 2002 I'm using VW 9.5.1 with Landmark and Renderworks, on a G3 Mac. It does happen in other files too. I thought it might be because the polygon cut into the object a fraction but when I've altered the polygon the same thing happens. Many thanks. Quote Link to comment
Guest Posted June 21, 2002 Share Posted June 21, 2002 Can you send in one of these files that you are having this problem with to tech@nemetschek.net and put it to my attnetion, please? I will take a look at it and see what might be going on and hopefully have a resolution for you. Quote Link to comment
Petri Sakkinen Posted June 24, 2002 Share Posted June 24, 2002 I think the problem is simply the non-planar surface you have created. A 3D poly, to render reliably, should either be in any of x/y/z planes or a triangle. Of course, theoretically you can create a planar 3D polygon in any coordinate system, but doing that with user-entered x/y/z values requires a lot of 3D trigonometry. In reality, only possible by scripting and/or PIOs. Quote Link to comment
