does Ogre 14 support single pass shadow support for pssm?

Post by loath »

does Ogre 14 have any examples (or RTSS) of the non-dx9 approach to PSSM with a single pass using geometry shaders?

see this article for non-dx9 pssm shadow support:

thanks!

this sounds like a nice way to bring down the draw calls (ogre1 achilles heel).

Unfortunately, there is no such demo yet and for PSSM there are some minor bits missing to get there.

I started writing a description for this with things from the top of my head here:

thanks for taking a look and considering this. i swear i saw you mention ogre had this but after reading the article i realized we have the dx9 "single pass" not the dx10 "single pass".
