CG Dynamic Gamma & Water Upgrade

#121 Hi alex...
Well i now added you to MSN..
lets talk about it tomorrow

#122 Greetings!

I'm enjoying quite satisfying looking of my game using this resource with TGE 1.4. Thanks again for this resource.
Today, I tried to bring this effect to my gun DTS and player. All I did was to add a line something like below.

addMaterialMapping("w_m99" , "normal: troup/data/shapes/weapons/m99a/w_m99_nm");

But there was no difference after that adding. I also tried 'detail' instead of 'normal' in above code. No luck either.

Do I need more to do to get what I want?
Thanks in advance.

#123 That only works if you bought Torque Shader Engine. This resource only effects the water and lighting.

#124 understand!
Thank you for your reply.

#125 I found out whats causing the problem with the sample size - you have to disable cg before you perform the readpixel operation. Otherwise the number of valid pixels you can use is messed up. I'll have an update loaded in a day or so.

#126 Trying to clean up some other bugs that have popped up during testing - For some reason my code is working in 1024 x 768 resolution, but crashes in 800 x 600. Just gotta step on this bug :)

#127 i noticed an issue
the water doesnt have any distance fog effect on it

so if your looking waaay down a river the banks on both sides fog out, but the water doesnt.. it looks very unnatural

#128 Yes, the water isn't really mine - I just try to keep it working in combination with the gamma effect.

#129 There is a bug with the waterblock when running on a system that does not support PS/VS.
The waterblock will render as a pink tone due to the surface texture being re-assigned to the normalmap texture.
To fix this bug, go to line 403 in waterblock.cc and change mSurfaceTexture to mNormalMapTexture.

#130 If you want to use the standard fogging with the shader water, go to line 900 in fluidRender.cc and move the text block to line 868. That will force fogging to be used with both standard and shader water.

#131 Paul could you tell me what was supposed to be in the text block? My version is apparently not the same as yours.

#132 Hmm, it should have a close bracket. I'm going by the source in the file linked at the top, so any merged code could move the position.

#133 Close to the end of fluid::Render in fluidRender.cc you will see code as follows:

// *****************************************************************
		//
		// Fog Map.
		//
		// *****************************************************************

		// *****************************************************************
		// TMU #0 - Fog Map.
		// *****************************************************************

		glEnableClientState ( GL_VERTEX_ARRAY );
		glEnableClientState ( GL_COLOR_ARRAY );
		glVertexPointer     ( 3, GL_FLOAT, sizeof(vertex), &(m_pVertex[0].XYZ) );
		glColorPointer      ( 4, GL_FLOAT, sizeof(vertex), &(m_pVertex[0].RGBA4) );
		glEnable            ( GL_BLEND );
		glBlendFunc         ( GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA );


		// *****************************************************************
		// Draw the Surface.
		// *****************************************************************
		glDrawElements  ( GL_TRIANGLES, m_IUsed, GL_UNSIGNED_SHORT, m_pIndex );

		// *****************************************************************
		// Restore State #0 - Fog Map.
		// *****************************************************************


		//-------------------------------------------
		// PRLD_WATER_SHADER
		//-------------------------------------------
		}
		//-------------------------------------------
		// PRLD_WATER_SHADER
		//-------------------------------------------

Change it to read:

//-------------------------------------------
		// PRLD_WATER_SHADER
		//-------------------------------------------
		}
		//-------------------------------------------
		// PRLD_WATER_SHADER
		//-------------------------------------------


		// *****************************************************************
		//
		// Fog Map.
		//
		// *****************************************************************

		// *****************************************************************
		// TMU #0 - Fog Map.
		// *****************************************************************

		glEnableClientState ( GL_VERTEX_ARRAY );
		glEnableClientState ( GL_COLOR_ARRAY );
		glVertexPointer     ( 3, GL_FLOAT, sizeof(vertex), &(m_pVertex[0].XYZ) );
		glColorPointer      ( 4, GL_FLOAT, sizeof(vertex), &(m_pVertex[0].RGBA4) );
		glEnable            ( GL_BLEND );
		glBlendFunc         ( GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA );


		// *****************************************************************
		// Draw the Surface.
		// *****************************************************************
		glDrawElements  ( GL_TRIANGLES, m_IUsed, GL_UNSIGNED_SHORT, m_pIndex );

		// *****************************************************************
		// Restore State #0 - Fog Map.
		// *****************************************************************

That will take the fogging out of the non-shader fallback code and put it in for both.
There is a slight issue with the edge of the visible waterblock, but it's a lot less noticeable than before.

#134 Well I got it to compile ok using cg 1.5 and tge 1.5 and it seems to work fine was just wondering in the FPS Starter kit / Strong hold demo when you look into the water I see a blue and cloudy sky even though in reality the sky is stormy snowing. Also when you look up from under the water you see the sky as blue and cloudy as well. Any Ideas.

Thanks

#135 When I compile CG Gamma & water on Linux with tge 1.5 i got the following errors message during linking with ubuntu dapper:

philippe@josie:~/cvs/torque15$ make

make[1]: *** [out.GCC4.DEBUG/torqueDemo_DEBUG.bin] Error 1

how to solve it ?

#136 i managed to get everything working on linux, but im not at home atm and cant tell you exactly what all i did

i did post a thread about it in the TGE/linux section though
also above i posted some info about it

i have TGE 1.5, and Cg 1.5

mostly there were alot of case sensativity issues (explained above) and i had to change the way it links (explained on the TGE/linux forum)

#137 Now the linking works , i have added these 3 lines to platform/GLCoreFunc.h :

GL_FUNCTION(void*, glXGetProcAddressARB, (const GLubyte *procName), return NULL; )
GL_FUNCTION(void*, glXGetCurrentDisplay, (void), return NULL; )
GL_FUNCTION(void*, glXQueryExtensionsString, (void *dpy, int screen), return NULL; )

it is OK the binary is generated.


But when I launch the demo now I get a core dump :

....

#138 here do this instead
http://www.garagegames.com/mg/forums/result.thread.php?qt=53032
this ways simpler, easier (probably a tad faster) less complex, and best of all, it works ;)

#139 Ok it works now but ... see picture below

warning message :

#######CG ERROR:Failed to initialize Frag shader! Hardware doesn't support any of the Frag shading extensions!

#140 That means it's time to upgrade your video card to one that support Pixel Shaders.
