Landscape Shadow-Mapping Demo (Sample)

[Hypnotron]

No.  You don't necessarily "have to" if the current shader does everything you need for it to do.

All the links here are dead, i'd love to see this project. Does anyone one know where i can get it?

Sorry, fixed now!

 has anyone kept the c++ conversion of this demo? the link seems dead and i would appreciate if anyone re-posted it or sent me.

thanks

Hello! I got this up and running now. However i'm thinking about how to get the meshes throwing shadows at each others too. Will it be possible for me to work out a way using this sample or must I go another way?

Maybe someone got an idea of how to solve it?

[Lenn]

For meshes to cast shadows on other meshes, i would recommend using PSSM shadow mapping by Mietze. You could (in theory) convert this shader to work on meshes, but it would take a lOt of work. Maybe you can combine the two shadowmapping shaders, hey who knows.

[Zaknafein]

It could work for meshes, but you'd have to follow a couple of guidelines.

The thing is that my sample has one shadowmap per landscape chunk, so you'd have to choose the right shadowmap for each mesh. Then to actually apply the shadowmap to the mesh you'd have to write a shadowmapping shader for them and figure out how to generate the right light-view-projection-texture matrix... I'm not sure how you'd go about that.

The easiest thing is really to adopt a global shadowmapping solution like PSSM. Mixing both sounds like a bad idea. (rendering shadowmaps twice)

Nice, becouse of that I must rewrite all my project   

Nice work and thanks for sharing it with community

@Zak, of course it's a bad idea, but i really have the impression he wouldn't exactly have the know-how to create a mesh shader based off of your landscape one.

@Sinisa, see you should search the forums for everything before beginning. And don't think this will be your last rewrite - there will be many more.
