How does the streaming part work? I don't think this article mentioned it.
- HellDunkel 5y agoMay be completely wrong but it looks as if triangles are subdivided to approximate the next lod level while avoiding cracks.
- kaetemi 5y agoIf you remove the triangle strips between two clusters of triangles, and represent them as one big polygon, it's "just" a retriangulation problem.
- kaetemi 5y agoAlternatively, for each cluster, render the edge triangles of the cluster at the neighbouring cluster's resolution with Z-write disabled, then render the cluster (overdrawing the real edge triangles), then render the Z-write of the edge. That'll reasonably fill the cracks with little overhead.
