[SOLVED] Clipplanes in opengl

[CuteAlien]

@Sinsemilla: irr::core::string::empty is only available in svn trunk, that was not yet in Irrlicht 1.7. So I guess you will have to install svn trunk for that (often the better choice anyway).

@CuteAlien: Thanks for the advice, by using the trunk the irr::core::string::empty errors are gone.

Unfortunately i still need a little bit help. The are 3 errors left which i don't really know what to do about. The compiler tells me that basically that the assingment operator for the class map can't be used. This happens in void CPostProcessManager::SwapAuxBuffers(), on this line of code:

Code: Select all

RenderTargetMap["auxIn"] = RenderTargetMap["auxOut"];

Anyway, many thanks in advance.

I could solve the problem by rewriting the line in SwapAuxBuffers .

In the meantime i compiled the little demo code. But somehow i have a weird water effect where the normalmap seem to shine through the surface looking like this:



Also the distortion seems to be too strong during the underwater view:



I compiled the example on Linux, so it all about GLSL .

[Sinsemilla]

And btw: as you can see the sky has changed. I am using a skydome. However, i first compiled the example with a skybox, which had the same effect as result. I could be also important to say that the windows example executed through wine is looking identical to the first screenshots posted in this thread (therefore it is looking as expected since the skybox error is visible):

[Sinsemilla]

I have a little guess: The only thing which is really different is the revision of the svn trunk, mine is probably never. @tbw which Rev. did you use for the example? i used rev. 4113.

[Sinsemilla]

After a little bit of trying i found out that the changes from rev 4105 to 4106 are causing the weird effect. So using rev 4105 is fine for me

I just checked the part that map's can't do the "mymap["foo"] = mymap["bar"]" thing. The reason is that core::map returns some AccessClass instead of just a reference to T. But I don't think that was ever different - so your code probably should use std::map instead (and maybe some day someone finds motiviation to dig into core::map and figure out if there is any reason for that...).

Hi, in a rev4106 we added support for an int uniforms and now in Your shader callback, You must bind a textures by int instead of float parameter, so eg:

Code: Select all

int Tex0 = 0;
dervices->setPixelShaderConstant("tex0", &Tex0, 1)0;
int Tex2 = 2;
dervices->setPixelShaderConstant("tex2", &Tex2, 1);

I think that we should add some note about this change (and improve example no. 10, because currently it usage wrong, floats type method). Bind a texture by a float interface caused problems on some machines (texture wasn't bind properly, but only in some cases, so was problematic for debugging and thats why I removed support for textures by a float interface and left only int interface for a textures).

BTW. In an OpenGL shader callback we use extGlGetUniformLocation call for an each setPixelShaderConstant call and this is serious fault (It can cause fps drop in an applications with many setPixelShaderConstant calls). In my opinion we should add a cache similar for this for vertex attribute locations in FVF stuff. For shaders, cache will be even simpler.

I used a rev earlier than 4106, because the new setPixelShaderConstant with int uniforms Nadro mentioned was not available.
I didn't notice the change though I look into this part of the code quite often.
@Sinsemilla: In which way did you change the swapAuxBuffer code (I want to change the code and upload a new version for the xml postproc framework)
I thing changing SwapAuxBuffers from

Code: Select all

void CPostProcessManager::SwapAuxBuffers()
{
        // swap the in and out buffers
        video::ITexture* tmp = RenderTargetMap["auxIn"];
        RenderTargetMap["auxIn"] = RenderTargetMap["auxOut"];
        RenderTargetMap["auxOut"] = tmp;
}

to

Code: Select all

void CPostProcessManager::SwapAuxBuffers()
{
        // swap the in and out buffers
        video::ITexture* auxIn = RenderTargetMap["auxIn"];
        video::ITexture* auxOut = RenderTargetMap["auxOut"];
        RenderTargetMap["auxIn"] = auxOut;
        RenderTargetMap["auxOut"] = auxIn;
}

should work
Also the water is nearly finished and I will upload it in the next days in the code snippets section.
Thanx in advance!

@tbw: Looks like this is the most obvious change possible. My code in SwapAuxBuffers looks exactly the same, this will definitively work. Even the variable name is identical
