CustomExporter Export Very Jagged Mesh for Curved Surfaces?

[Anonymous]

As shown in the screenshots below, when I tried to export a curved surface, the OnPolyMesh method in IExportContext gives very jagged edges. Is there a way to solve this?

Thanks!

Not very much you can do, I believe.

You should however at least read these two posts:

• https://thebuildingcoder.typepad.com/blog/2015/06/angelhack-athens-sustainability-and-export-precisi...
• https://thebuildingcoder.typepad.com/blog/2016/02/reorg-fomt-devcon-ted-qr-custom-exporter-quality.h...

I all else fails, you will have to access the real element geometry instead of using the custom exporter.

That is normally a lot more work, though.

My solution is to triangulate the face in OnFace method, in this way I can input a LevelOfDetail parameter. However I lose all UV data at the same time. Currently I use Face.Project to approximate a set of UV which is quite unstable.

Thanks for your reply anyway!

I've also tried to set LevelOfDetail property on ViewNode, and it also works.
