Deferred Rendering

Am I right that this doesn't support EMT_TRANSPARENT_ALPHA_CHANNEL(_REF)? I tried to use it and graphics got screwed up.

Is it the XEffect shader code used to render shadow maps ?
How do you plan to do point light shadows without 6 more pass ?

ALPHA_CHANNEL is added i think. REF is not bc i didn't need it.
anyway will release source code soon.

what ya mean with XEffect shader code? my system works completly different. objects are drawn from the lights not by them self. but my vsm code is inspired by XEffect shader code.
Anyway i will render the shadowmap for the pointlights in a single texture. this will probably result in bad quality when the texture is to small.(6 images must fit into a single texture). that way only the depthmap will require 6 instead of one pass and the shadowing itself is done in a single one.

Hi, I have a problem :S
when i change the mesh in my IAnimatedMeshSceneNode's using setMesh(), they completely disappear :O normal scene nodes that are just sitting in the scene (not modified at all) are not affected.
This doesn't happen when I'm not using the deferred renderer, so I'm wondering if you could shed some light on this?

Thanks

Enabled the option to set the shader directory as requested by entity.

Just wanted to say this project isn't dead yet, same for EditIrr. when i get my new project of the ground both of these will get updates bc i will be using them myself then again.

Hello, Sudi!
Deferred Rendering it's very cool add-on for Irrlicht.
But what about attach to it the bumpmapping?

when u give me the formula to transform the texture normals to worldspace its as good as done

You're more than welcome to use my HLSL shaders off my site and incorporate them, I too would love to see this running from HLSL.

Just click on HLSL shaders on the DirectX 9.0 tab, I have a ton of samples there.

I'm working on an unrelated deferred system in HLSL. I'll share it when it's decently finished.

Very nice, can't wait to see it.

Any updates on this?

I tried the download in the first post, the vs-dll's doesn't contain any exported symbols of interest. I'd very much appreciate this being fixed. I'd love to write a deferred render system myself, only i've no time to =/

Got this working

Is there any way to use this with my own shaders? Just on objects, for example have my box use a glass shader or water shader?
Loading my shaders and applying them with setMaterialType(), but it looks like your deferred rendering is overriding them.

here you have the code for pass the tangent normals to normals in view or word space, only change the matrix view * world for world only.

Hi Sudi! Thanks for developping this addon! I still have to check how this is workingand need to read more about deferred shading. Seem to all be done in shaders. I hope more work will be done with this. I think it's the only project on the forum that could allow us to do this!

If it's of any help, you can check out how I'm doing it: https://bitbucket.org/entity/irrrenderer

@all: i know i should probably make a new topic about it and stop hijacking this thread... but then everyone will start complaining

Also, spot lights seem to be a bit bugged

edit: i'm at least gonna push the latest changes that add linux 32 bit build targets
sadly, it won't run properly on my linux machine, but others have reported that it works just fine for them

Irrlicht Engine

Deferred Rendering

Do you think this is usefull and needs further improvements
