irrRenderer 1.0

[ataxxdog]

This is cool. irrRenderer is what got me started with deferred rendering, and XEffects helped me with shadows. So far I've re-implemented an entire system with:

- deferred rendering
- normal mapping
- specular mapping (shininess)
- Blinn-Phong BRDF
- dynamic shadows for point, spot, and directional lights
- variance shadow mapping (soft shadows)
- cascaded shadow mapping for directional lights (with VSM soft shadows)

There is also some basic post-processing support, which is currently only used to render a box blur for VSM.

I'm talking to our people about making this code open-source. Would anyone be interested in contributing, integrating it with irrRenderer features, etc.?

Here are some renders to show what I'm talking about:





Also some videos:

Spot lights w/ shadows: http://youtu.be/0NLhZXBtJYs (Note: this is an older version, where some red specular reflections were appearing incorrectly on the robot.)
Point light w/ shadows: http://youtu.be/yRkTy0fb-vw

EDIT: Sorry, I realized that I kinda hijacked this thread. I really just wanted to see if there are opportunities for collaboration, especially since ent1ty's code helped me a lot and I want to give back somehow. I hope this is making sense

Wow, looks great mate.

[ent1ty]

That, indeed, looks awesome.

Not me, I'm busy with mobile dev, at least for this summer

I've been having some issues implementing this.

I had a look at the documentation and the example that you have on there comes up with an error with

Code: Select all

renderer->getMaterialSwapper()->swap();

saying that CMaterialSwapper doesn't have a member called swap.

I'm assuming the example there .. is out of date? I've been scouring the docs to figure out how to get past this. and i'm really short of ideas.
I'd love to use this renderer as I've got a little village i want to be lit up with lanterns etc etc.

any ideas?

Whoops completely missed your post... bad timing Yes, the fuction's name has been changed to swapMaterials: http://www.fi.muni.cz/~xkrupick/irr/doc ... apper.html

[prodcake]

Haha thought as much, no problem anyway, thanks for the help!

edit:
now that fixed the material problem, but now it's coming up with the same error as it did when the renderer didn't swap materials.

Code: Select all

undefined reference to `_imp___ZN3irr5video16IdentityMaterialE'|

[ent1ty]

You're not linking with Irrlicht properly (the error you're getting has nothing to do with irrRenderer... at least I don't think. But I'm remembering now I was getting some weird linking error I couldn't quite understand the reason behind when I forgot to initialize irrR. with the create function, not sure if this is the case.)

[thanhle]

Hi,
The documentation need to be updated.
The example code from the document doesn't work due to change of function calls.
Missing: getMaterialSwapper()->swap();
Missing: CRenderer::drawAll()

One question: Is this still work with latest changes in trunk? My render scene is pitch black.

Also, I get memory leak upon close device.

Hmm.. the docs are definitely outdated in parts. As for the crash, I haven't tested this for quite some time and indeed, the project is pretty much abandoned at this state. I did however want to try it out the other day, but to my horror I discovered the only way to build this project is to use code blocks! So I may try to get it into a working order (add a Makefile!), if I do so I'll post here.

Thanks for taking interest btw

[ent1ty]

Okay, so I have added makefiles and updated the docs (actually all that needed updating was the short example on the index page. At least I think - if there's something else wrong, let me know). You can find the new docs here: https://osense.github.io/irrRenderer. About the crash on exit - not sure what exactly is going on, I'll try and see if I can find what's wrong.

[devsh]

you might want to use Cook-Torrance lighting model for your metal mech, Blinn-Phong is only good for plastics and skin

[ent1ty]

Ah if I am going to do some work on this in the future, multiple lighting models is very far down the to-do list I haven't even the shader callbacks to stop using calls deprecated after 1.8. Plus, I would really like to know how much everything gets broken when the shader-pipeline is merged into master. I haven't checked that branch at all, yet.

[thanhle]

Hi mate thanks.

That works fine see image below for 903 point light test.
Some how I can't get light to lit static mesh, do we need to do any setting for that?
Also if I resize the window do you have any method to update the renderer to the New size window?

PS: Looks like the dude with the robot picture above "ataxxdog" release the combine render sourcecode. See below link. It's good if you can integrate that .

Hi Mate,
If I don't want the back ground to be black. Where do I change that?
Without deferred. I just change it at beginScene. Where can I set it to use that color in

video::SColor color(255, 100, 100, 140);
device->getVideoDriver()->beginScene(true, true, color)

Another question:
I found that scenenode needs texture for deferred render to work. Is there anyway to make it work with no texture?

Thanks
thanh

Some how I can't get light to lit static mesh, do we need to do any setting for that?

Check that you have the correct material set.

Also if I resize the window do you have any method to update the renderer to the New size window?

Calling clearMRTs and then createDefaultPipeline should recreate the renderers MRTs for the new window size. See https://osense.github.io/irrRenderer/cl ... derer.html.

memory leak when exit.

Yes, I know about this, the IDE I'm using has transitionally broken the debugger plugin Will have to figure something else out - if you could send me a stacktrace, that would be immensely helpful.

Parallax shader error:

This fixes things for nvidia compilers, but breaks them for the mesa linux driver. I will change it to #version 140 in the repo though, as that is what the standard requires.

If I don't want the back ground to be black. Where do I change that?

irrRenderer uses render-to-texture internally and clearing all the textures each frame would likely lead to a performance drop. Usually, you want to have the whole viewport filled with geometry anyway.

I found that scenenode needs texture for deferred render to work. Is there anyway to make it work with no texture?

Yes, you can write your own material shader Start with the solid shader and modify it to your needs.

Thanks mate,
Just need to see your reply to confirm that this render is till alive .

Can I use your post processing with this render . Is there any example?

Thanks
