Graphical Flooding?

[Rubini]

Just some OT comments (sorry) but at least have something in common:the sh3 water...

days ago i was looking at the Sh3 shadows issue again and as the ships (stock at least) have out of the box nice shadows and the uboats too (we can live without shadows on crew)...seems that the main problem is how to cast shadows over the water (ocean). The hard point is that the ocean isn´t a "visible" 3D object on sh3 files, so we can´t put on it the dynamicsShadows controller...so my question is : with the Seeadler's input above (ocean pixel shaders) we can have again some hope to have shadows cast on the water?

Dont worry about it being off topic, I just really want to know what that there chunk of information is. And what I dont get though, is why we cant have transparent water, I mean, its set so you can see up and out of the water (Looking up from external view you can see ships and such from underwater) but why cant you see down IN the water ?? I want this so badly, you dont even know. That and the shadows are a good idea too

Yes it´s true. If we could change the water pixel shader perhaps we could have finally transparent water! Yeah!

Hi shipmates,

This is very early stage compartment flooding test. the water is not showing with the reflexion pass only a rough render to see how it's look in game.

The final render take a long time to do but the result are photorealistic.

I also lower the opacity so we can see objects and crew foot under water.

The water will be animated in 2 ways on the base plane that represent the water and on texture so the look will be very realistic and framerate shouldn't have a very big impact since it is a very low res object.

Also the water plane have 3 different animation height in CR i call those states : 25%,50%,75% will also be easier to link them.

I think i found a way to link the water to the flooding value i will test it further in the weekend, what i want to achieve is to make the water raise to match the flooding percentage or another controller that could do the trick.
Here some early test pictures at day&night :





Best regards Hans

HOLY BUGGER First we have expanded interior compartments, now internal flooding... I think wolfpacks are not far off at this rate

If you somehow get that finished before all of HAHD and would release it as a mod compatible with GWX 3, I think I would die. Just sayin

Good work Hans!

Truly amazing.

At this rate ShIII will be the NEW SHV!

Hi mate,

Don't worry ain't no photoshop there

Outstanding work Hans! Congratulations on achieving a true milestone!!

Maybe!

In my widescreen dll I have hooked the DirectX function CreatePixelShader() and then dissassembled the buffer with the actual pixelshader code and dump it in a text file. Now I have every hardcoded pixel shader of SH3 as asm shader source code in separate files.

Unbelievable but SH3 uses only 5 pixel shaders

1 = shadow shader
2 = water reflection shader
3 = water shader
4 = terrain shader
5 = ??????

in comparison SH4 approx 200

Now in a second step I loaded this simple asm shader code

ps.1.1
tex t0 
mov r0, t0

from a file into the buffer and replaced the hardcoded water shader with it. This shader code simply takes the texture stored in register t0 and moves it to the output register r0



This is just a proof of concept to change the pixel shaders in SH3 from external files such in SH4/5. It needs allot more work, ...extend to shader version 2.0, make use of more texture registers, storing own textures in the registers and so on...

Hi mate,

Outstanding work

I try many time in the past year to make water transparency with no sucess but since i have experience in 3d i know that the reflexion use in shader might be the culprit to it.

If you go in Scene.dat and go in EnvData controller there is a water opacity set to 255 even if you change the setting nothing change in game water remain exactly as before so you can clearly see that they were planning to implemented transparency but for a reason they abandon the idea.

I also try to open the SeaInf.Raw in Env folder and change the alpha to get transparency and nothing change in game i wonder for what they use that file in game and you see here in Env.cfg it is active :

[Environment]
SeaTypeImageDimX=4320
SeaTypeImageDimY=2160
LandIDX=255
DefaultSeaType=0
SeaTypesNo=1

[SeaInfo01]
StartDate=0101
EndDate=1231
SeaInfName=SeaInf.raw
Compressed=NO

[EnvColors]
SeaType00=EnvColors_Atl.dat
SeaType80=EnvColors_Med.dat
SeaType150=EnvColors_Arct.dat

[SkyColors]
SeaType00=SkyColors_Atl.dat
SeaType80=SkyColors_Med.dat
SeaType150=SkyColors_Arct.dat

I know how shader work but unfortunately i cannot read C++ shaders coding.

Best regards Hans
