Helix Toolkit 缩放时颜色渗色

[英]Helix Toolkit Color Bleeding on Zoom

Using the Helix Toolkit I can see colors bleeding through when zooming.使用 Helix Toolkit，我可以看到 colors 在缩放时渗出。 The closer I zoom the better it gets, zooming out make it worse.我放大得越近越好，缩小会使它变得更糟。 Is this a problem with the HelixViewport3D or my Obj model?这是 HelixViewport3D 或我的 Obj model 的问题吗？

This appears to be an issue with model interference.这似乎是 model 干扰的问题。 Either in (A) the CAD software as modelled features or as (B) exported mesh or mesh duplication or mesh tolerances tolerances/interference between vertices.在 (A) CAD 软件中作为建模特征或作为 (B) 导出的网格或网格复制或网格公差公差/顶点之间的干涉。

Suggest first investigating the model/assembly to see if there is any interference (most parametric software has an interference check as well as settings to change the part accuracy which will influence Tessellation later.建议首先调查模型/装配体，看看是否有任何干涉（大多数参数化软件都有干涉检查以及更改零件精度的设置，这将影响以后的镶嵌。

Second if part/assembly is modelled correctly with no interference and part(mesh) tolerances are apt.. Export with if options allow a reduced 'cord height' for smoother features.其次，如果零件/装配体建模正确，没有干涉并且零件（网格）公差很合适。如果选项允许减少“绳索高度”以获得更平滑的特征，则使用导出。

Third, taking the model into Blender for example and merging vertices.第三，以model为例，将顶点合并。 If you use Sketchup or another surface modeller or even a parametric CAD software but utilising surface models these may have somehow been occupying the same vertex values.如果您使用 Sketchup 或其他曲面建模器，甚至是参数化 CAD 软件，但使用曲面模型，这些可能会以某种方式占用相同的顶点值。

Hope this helps, but normally it is modelling that causes the issue that has a downstream impact.希望这会有所帮助，但通常是建模导致了具有下游影响的问题。
