Real Water question

| Hi, i working in a own ship game in blitz3d. i'm trying to make a good and realistic water. for the moment, i using plane water from fastlib and is excelent calm water with reflect and refraction. i Using 3D mesh water moving vertex to simulate waves movement. the question is, with dx7 and blitz3d, there is any way to create water like this? using libs, or something? https://www.youtube.com/watch?v=ykPjzV9Z5Ew thanks and sorry my english! |
| ||
| no |
| ||
| Mesh Water, Animating sample on Fragmotion. |
| ||
| Using libs.. Yes, by choosing the best wrapper if not B3D, Blitzmax. If you really like to stick with B3D, my best bet is SoftPixel because of the DX9/DX11 rendering. DX11 is experimental as noted on their site. http://softpixelengine.sourceforge.net/download/SoftPixelEngineWrapper.zip http://softpixelengine.sourceforge.net/forum/viewtopic.php?f=11&t=42 Those wrappers seems outdated though, you may need help or some work but still depending on your usage. I'm looking into the wrappers myself as I already forgot about this and just remembered picking it up again recently. I think your keyword here in making those realistic water is "Tessellation". ;-) Nvidia always comes first with some fancy graphics tech to showcase their hardware, this is similar to the Unity DX11 water you posted above |
| ||
| Hi, I 've looked at a sample of water in the examples Blitz3D shows a choppy sea and I think you can improve with Faslibs . The example is called water,  |
| ||
| Softpixel supports tessellation but I don't know how far it goes or if it is complete/stable enough for production. Look inside the media folder, you'll find ShaderTessellationHLSL.txt but has no usage in those given examples, you have to ask the author (LukasBanana) |
| ||
| @Yue, That's only a simple water example that you can get away with mobile. As long as you have access to Shaders and if SoftPixel's DX11 is good, it should be possible. You cannot create your own Shader with Tessellation in FastLibs. |
| ||
| hi, ok!, thanks!. i see now , Tessellation is the secret! Blitz3d is so compatible with all PC, and the only limitation is the graphics realism. i choose blitz, i don't like Unity, and other lenguages. so, i continue the search for good waters using dx7 this is my first 3dwater, the color of water is becouse is a river.  |
| ||
| maibe make something like this, is a good way. but the shaders?, the sunshinne :( https://www.youtube.com/watch?v=C3UelEn15Sc |
| ||
| That's nice. Yes, with using wrappers you are still using Blitz3D but with that you have to adjust to other context like 3D Sound and Collision since you are enabling another engine. so, i continue the search for good waters using dx7 The best water I have seen so far in dx7 is fastlibs and ashadows, nothing comes close. I don't know about other demos but these two stand out but as you can see it does not even compare with today's new water rendering with realism. I already have asked this and like you has some interest in improving Blitz3D effects but you can't do it without any help from other engine wrappers while maintaining B3D language code. Unless you have an extensive knowledge in C/C++ Graphics/Engine Programming where you can tear up old DX7 blitz3d source code and convert it to DX9/11. Speaking of which, you can check out Ploppy's HardWired Lib, but that's far from being stable and can be used in production. I would suggest studying Shader Programming and pick between your preferred renderer (DirectX 9/11 or OpenGL) and then pick an engine wrapper that works for you and Blitz3D. |
| ||
| but the shaders?, the sunshinne :( sunshine? if you're talking about Fastlibs Light Scattering, it can be done using Shaders and you can find lots of information about that. :) Everything that FastLibs and Ashadows offers is now possible even now have some improved versions like the water tessellation you see there. |
| ||
| Real Water here. https://www.shadertoy.com/view/Ms2SD1  |
| ||
| Yeah, but contrary to what I've seen with fastlibs it's dead slow under softpixels. But hey perhaps it's just my old 2007 laptop or I've not seen/tried the latest version.. [edit] @Yue: That's some awesome water. I'd expect a shark to come out of there any time. Full screen is a tad slow on my machine though. |
| ||
| Here's a nice piece of code from way back in the forum somewhere with a few changes I made... and also my path to the 20by20 3DS quad file and my local image file.. I can't remember where in the forum I found this years ago.. |
| ||
| Would love to try and run this, but.. eh, media for this? Also: is this quick enough to be applied in a real live game environment? |
| ||
| Ok Rick I looked it up.... the original code is in: Blitz3D Code archives/3D Graphics - Mesh/3D Water "3D Water by CyBeRGoth" It has a 60 kilobyte media download in the archive of textures. As for the water texture I used there are HUNDREDS of them for free on the web- you don't need the moon thing- the graphic there is one I got from the JPL Nasa Pluto Mission site. So it looks like Cybergoth had a animated texture- I just used a plain old .png file - remember that textures have to be a multiple of 8- 32x32 64x64, 128x128, 256x256 etc, So in an old program I did the animated Quad mesh moves with the ship mesh- basically that isn't much overhead |
| ||
| OK gpete, that seems doable and I probably already have the JPL Nasa pluto texture as I was using that for a planetary sim a while back :-). So then the major question: -What does it look like? Can you post a screenshot perhaps so we can see what results we're actually talking about. -Does it rival FastExtensions water? (currently using that one) |
| ||
Here test, |
| ||
| ... |
| ||
My Water, no FastExt, no Ashadow. |
| ||
This is the best water I've seen in Blitz3D without libraries . |
| ||
| Hi! the montain water looks very good!, can you upload more image of that water? |
| ||
Here Code Water only Blitz3D. |
| ||
| @Yue. -1st picture doesn't look good to me. -2nd picture looks good, but no waves so is a bit too much like a mirror. -know that demo. Indeed very nice, but not really useable for open worlds scene I think. |
| ||
| @Rick Nasher Yes, this sea has waves , set plays  |
| ||
  |
| ||
| Ah, yeah see it now, well done. |
| ||
| @Yue: Can you post the source & any needed files to that water generator code so others can have vertex-water as well? :) Thanks! ~GF |

| Can you post this 1 too? This is the one I'm after. I tried WATER2 and it was only blue water. What I need is clear water where the vertices are moving. Thanks Yue! :) ~GF |

| ||
| Thanks ALOT Yue! Simply BEAUTIFUL! =D ~GF |
| ||
| This a rather nice looking water for all blitz code. Only pity that such things only work under a certain angle, which limits the usability. If you change the line If KeyDown(208)Then If EntityY(camera)>3 MoveEntity into: If KeyDown(208)Then MoveEntity camera,0,-1,0 ;If EntityY(camera)>3 You'll see what I mean. Nevertheless, very nice little piece of code, I wouldn't have guessed it was possible like this. Many thanks, I will use this somewhere I am sure. |
| ||
| To me what intrigues me most of all is that you can still learn a lot from Blitz3D in terms of programming . |
| ||
| Thanks Yue! is a excelent water!! for lakes waters i test in my 3dWater, but only works in a calm waters, becouse the cubemap not work in 3D big waves.  |
| ||
this is my water without cubemap |
| ||
| Can you please post this demo, Santi so others can learn? Thanks! ~GF |
| ||
| is a work in progress, i wish to finish the demo in dicember. i have a lot of work to finish the demo becouse is a very big project. here is a video of the scenary editor, work in progress |
| ||
| I think for the wave cubemap work you have to change the distance of the camera from cubemap. I just speculate about it. Edit: Power Full Video Santiago. :) |

for wavemesh i have a big quad mesh, i move vertex using this funcion;!

| is important this aspect for wave mesh 3D you have a quad mesh (Plane) you move the Y vertex (up and down) using sin(time..) and if you MOVE the vertex horizontal, (vertexX) you simulate a soft surface of water. x# = VertexX(surf_agua,v) y# = 0;VertexY(surf_agua,v) z# = VertexZ(surf_agua,v) For w = 1 To waves dir = w * 30 y = y+Sin(dir+(z*waves*fdz+((x+waves)*fdy)+(wave_cicle)))* f_alt Next ;! THIS IS THE HORIZONTAL VERTEX MOVEMENT!!! x# = x + Cos((z*fdx)+MilliSecs()*f_vel)*.05 |
| ||
| the problem, is very SLOW move big count of vertexs. in the Image you can see i have 30 FPS, very slow! |
| ||
| o no problem, santi. I just wanted the water part of it. =) ~GF |
| ||
| Oka, i upload media textures tomorow AAnd the to ccodeauncticreatefunctionr. |
| ||
| Great, thanks Santi! =) I look forward to it! Regards, ~GF |
| ||
| I Upload in code Archives my 3dwaves http://www.blitzbasic.com/codearcs/codearcs.php?code=3281  im shure this code can be improved!!  |
| ||
| Nice, Santi world! =) It would be nice if you could manipulate the vertices instead of loading a texture! =) ~GF |
