Andrew Owens Posted February 18, 2003 Share Posted February 18, 2003 I am very disappointed with the image quality of transparent objects in version 6. As most IC users probably already know, in the previous few versions, after you edited the cross section of any Intellishape, the rendering of transparent objects in the scene would miraculously change from pixilated to photorealistic, it was fantastic. This is no longer the case. Why couldnt you have just turned the excellent rendering mode on permanently when IC starts? What's the story with this IronDudes? I have been extensively using transparencies to visualize and position complex mechanisms into very tight spaces. Now that transparent objects render only in a pixilated mode, the whole experience of transparency visualization in IC is considerably diminished! IC 6.0 has a lot of great new features, but Ill have to consider this issue a downgrade.

Chris Lohman Posted February 19, 2003 Share Posted February 19, 2003 We fixed some transparency bugs in 6.0 that would cause the parts to render incorrectly. I doubt they intentionally "turned off" the nice rendering that you mention but they probably fixed some bug that had an impact on that "bug". I'll look into it.

Chris Lohman Posted February 26, 2003 Share Posted February 26, 2003 Yep, a bug fix in 6.0 was the source of this change. They are continuing to work on transparency for future releases. Quote Link to comment Share on other sites More sharing options...
Andrew Owens Posted February 26, 2003 Author Share Posted February 26, 2003 I hope so! How about a service pack fix Quote Link to comment Share on other sites More sharing options...

Guest dlalonde Posted February 28, 2003 Share Posted February 28, 2003 I thought the transparency problem was limited to Nvidia products only. We have been seeing several problems with the Nvidia cards. But as I type this, I remember that my old 3dlabs GVX1 card had the same problem with transparency. I have confidence that the Irondudes will fix it. Dave Quote Link to comment Share on other sites More sharing options...

Cary OConnor Posted July 8, 2003 Share Posted July 8, 2003 Hi Andrew, I may not be the right person to answer this, but I'll give you as much detail as I know. In previous versions of IronCAD, the rendering you saw in the 2D Cross-section was based off of an OpenGL option. The issue with this is that it was Order Dependent based on the scene browser. What that means...in the 2D cross-section mode, geometry may change its viewable state and become hidden due to the order in the scene browser (not based on the view direction in the scene). In the other modes (outside of 2D Cross-section) the graphical display is not order dependent of scene browser and would give the correct display. The change in 6.0 made it so that the display would not be order dependent, hence losing the nice graphical display on the transparency. We are looking at our graphical display and settings for the display of transparent object and hope to have a good solution over the next major releases. Hope this help explain why the sudden change (it is for the better in most cases ). Thanks, Cary Quote Link to comment Share on other sites More sharing options...
