I'm using this water scene node with xeffects and it seems to have some problems with:

RealisicWater.cpp

Code: Select all

VideoDriver->setRenderTarget(RefractionMap, true, true, video::SColor(0,0,0,255)); //render to refraction

VideoDriver->setRenderTarget(ReflectionMap, true, true, video::SColor(0,0,0,255)); //render to reflection

With these lines screen is just black. Commenting them makes water ugly but there's some image on the screen.

First of all i tryed commenting:

Code: Select all

VideoDriver->setRenderTarget(0,true,true,video::SColor(255,255,255,255));

Because that rendered texture should pass through xeffects but that makes no difference. Screen is black. Have anyone using it with diferent postprocessing? How?

I had this node working a week or 2 ago (got a few warnings on compile tho) then I switched from codeblocks to dev-cpp and now I have this lovely stuff

Code: Select all

EDIT: I managed to make the errors go away and the water looks pretty good except for the small detail that the water plane is perpendicular to the terrain.

Code: Select all

  Water->setPosition(core::vector3df(0,0,0));

irrlicht is missing one small feature... it is getting the current render target... it causes problems

render to 0 or some rtt in case of xeffects
then render to refraction (which is fuckloads inefficient because the render target above could be copied to this one)
then render to reflection
then its supposed to render to screen!!!! or to the "some rtt"

@devsh,

It's not in my refraction demo but I didn't find it too hard to render the scene, preserve the depth buffer and then render the transparent refraction object without having to do another pass, all you do is not clear the zbuffer, copy the rtt to another (Using a screenquad or something) and then use the copy to refract. The only issue is the clipping, but there're ways around that.

We do plan to add faster, low level copying functions so you don't have to use the screen quad. There was a snippet on the forums for "copyBackbufferTo" which I use quite frequently in my own projects as it allows me to do anti-aliasing on the backbuffer (Not allowed on RTTs in D3D9) and copy it over. You could use this for copying the refraction aswell. I couldn't get the OpenGL implementation working though which I posted in the same topic but I feel that I was very close.

Cheers

Pictures are down, could you republish them?

This code wrong work on 1.6 irr with nVidia card... 9600Pro

[oldskoolPunk]

Anyone still using this? The refraction looks good but my reflection is messed up. Here is a render of the reflection.



Seems I had this problem with shadow projection too ...

[oldskoolPunk]

Hey I got it!


I had to change a line in onAnimate

from

Code: Select all

CurrentCamera->getPosition();

to

Code: Select all

CurrentCamera->getAbsolutePosition();

because of my wacky camera setup.

Thank you!

OpenGL seems fine here in irrlicht 1.5, from some angles ...

[devsh]

make changes to the shader... can you see the wacky edge on the left side

clamp()

Hi!
Haven't visited this forum for about 2 years. Had to do my own things. Sorry for not replying to your messages. I don't know what happened here for all this time, but it seams that you are still using this scene node. So I guess my duty is to make it up to date and fix things I didn't fix back then. Whenever I have some free hours, I will try to fix it, if still needed of course.

[BlindSide]

Sorry I had to

Nice to see you again elvman

I guess we should move this node to irrext in order to have it more easily accessible. Please notice me once you're done with updating and I'll add it to the repository.

[elvman]

Ok, hybrid.
