silhouette and PostProcess

Hi,

I am using the post-processing to display the model outline function, but I found that when there are other models before the model and the camera, this contour will no longer be the true contour of the model.

Is there any way to always display the true contour of the model?

This is because the silhouette is computed in screen space I believe. So it’ll efficiently compute this outline no matter how complex the geometry is, but it only does it on the visible area of the model.

This has been requested in this GitHub issue as part of making untextured 3D buildings easier to see: https://github.com/AnalyticalGraphicsInc/cesium/issues/7870

Is your goal to be able to see just the outline, or to render all edges like in this forum thread? https://groups.google.com/d/msg/cesium-dev/CwV4UxoEoKM/uS5k8kCJBAAJ
