Hi,
My goal is to build an indexed list of triangles from OGR polygons as
inputs to a hardware rasterizer for efficient rendering. I see RFC 64
was implemented a few years ago but the documentation warns "not yet
implemented".
-->where exactly do you see this mentioned?
Anyway, tesselation as triangles wasn't in the scope of the RFC
But you might want to use OGR_G_DelaunayTriangulation()
These is reinforced by my failed attempt to use OGR_G_ForceTo on a
polygon geometry to the TIN type. OGR's object hierarchy can be easy
to misunderstand so maybe I'm just missing something here.
Is this functionality available? If not, are viewers like QGIS
manually building an index list themselves (or perhaps they use old
fixed function APIs)?
Thanks,
Jesse
