Horst M. Posted October 11, 2013 Share Posted October 11, 2013 Hallo, I did a model with some simple Extrudes (pusch Pull tool), and viewed it in Open GL with Draw Edges enabled. The result doesn't show all edges. Anybody Eles seeing that? Image attached. Note: I wasn't shure if should post it here or in the "Renderworks" Forum. The Moderators may move the Topic.

michaelk Posted October 11, 2013 Share Posted October 11, 2013 (edited) Yes, I have noticed this. I've been meaning to submit a bug report. In OpenGL lines inside the outer perimeter of the current view of Solid Additions and Subtractions (I haven't tried Solid Intersections or Sections) don't get drawn. This is what I'm seeing: Edited October 11, 2013 by michaelk Quote Link to comment
Patrick Fritsch Posted October 11, 2013 Share Posted October 11, 2013 Same has been happening here. Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted October 11, 2013 Vectorworks, Inc Employee Share Posted October 11, 2013 (edited) Confirmed, edges are drawn as expected in Hidden Line here, but not with OpenGLs Draw Edges. I can see the properly drawn edges only when editing the various solid additions. Submitting now. Edited October 11, 2013 by JimW Quote Link to comment
Vectorworks, Inc Employee Dave Donley Posted October 11, 2013 Vectorworks, Inc Employee Share Posted October 11, 2013 This is working as we expect it to, for now. The OpenGL Draw Edges option shows edges between different objects. The subtraction is one object so no edges are drawn between its parts. It is a wish that the OpenGL Draw Edges would do more analysis of the object to determine edges, which would affect the speed. For now if you really really need to see edges between the parts of a subtraction etc. you will have to convert it to NURBS, or render in hidden line which does the additional analysis stuff.

Vectorworks, Inc Employee PVA - Admin Posted October 11, 2013 Vectorworks, Inc Employee Share Posted October 11, 2013 Switched to a wishlist item submission instead. Quote Link to comment
Patrick Fritsch Posted October 11, 2013 Share Posted October 11, 2013 While were at the wishlist, please check out the attached pic of how the Open GL "drawedges" option affects a DTM. It seems to pick up some of the triangulations and draws their edges. This should be fixed. Quote Link to comment
Kevin McAllister Posted October 11, 2013 Share Posted October 11, 2013 There is something really interesting going on here that NV should take note of - it shows that it would be possible for VW to draw a heavy outline around an object (essentially the current behaviour of OpenGL lines) and have internal lines (the additional lines drawn by hidden line) be a lighter line weight.... Implementing this would go a long way to improving graphic presentation of viewports rendered in Hidden Line. Kevin Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted October 15, 2013 Vectorworks, Inc Employee Share Posted October 15, 2013 (edited) Patrick, Looks like this was corrected in (the just released) SP1, tested here and I no longer see those random triangles. http://www.vectorworks.net/downloads/ServicePack.php?major=2014&servicepack=1 The OP of this thread however, was indeed submitted as a separate request.

Patrick Fritsch Posted October 15, 2013 Share Posted October 15, 2013 (edited) Hi Jim, check you email inbox! I'm getting different behavior on another file. The SP1 did in fact remove the traced DTM triangles on the first file I sent as you confirmed, But on another file (the one just sent) all the triangles of the DTM get traced when I check the "draw edges" option box of the Open GL settings. (Note: it's the same DTM, just the different site modifiers applied to it...If you delete the rear most retaining wall site modifiers it removes the offending traced triangles??? Bizarre indeed!)

Vectorworks, Inc Employee Dave Donley Posted October 16, 2013 Vectorworks, Inc Employee Share Posted October 16, 2013 The initial screenshot and your description makes me think there is overlapping geometry in the "too many edges" case. Like a zero offset between different surfaces or a copy of the same geometry in the same location. Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted October 16, 2013 Vectorworks, Inc Employee Share Posted October 16, 2013 Patrick, It looks like for this other DTM, the issue is related to one of the retaining wall site modifiers directly. Removing it, but making no other changes, corrects the rest of the file. (Images attached) If you recreate this modifier as a test, then update the site model, do the lines reappear?

ray isaacs Posted October 16, 2013 Share Posted October 16, 2013 patrick, did you try rendering in fq renderworks? the reason i ask is that the same thing happened to me recently in open gl. when i subsequently rendered in fq renderworks, i saw that the mesh smoothing was no longer working. when i removed the most recently applied site modifier, both mesh smoothing and open gl functioned as expected. i still don't know why. sent the file to vss tech support and haven't heard back. ray Quote Link to comment
Patrick Fritsch Posted October 17, 2013 Share Posted October 17, 2013 Hi Jim, I just deleted those two retaining wall site modifiers at the back of the site and did new ones, and all is fine now. It may have caused something to go wrong when I copy/pasted the original retaining wall, perhaps similar to how stair PIO's are not recommended to be copy/pasted. Ray, all rendered as expected in FQ Renderworks, even with the problem site modifiers. Thanks, Quote Link to comment
ray isaacs Posted October 20, 2013 Share Posted October 20, 2013 thanks, patrick. seems like the problem i'm having is of a different nature. ray Quote Link to comment
