LWJGL water shader demo.

[bobjob]

I havnt posted anythiing in a while so heres something i have been working on:

Water Shader Demo

Controls.
Light Source: w,s,a,d,q,e
Spin: spacebar
plane size: y,u,h,j,i,o,k,l

Debugging:
Disable VSync: enter
height size (decrease, reset, increase): Numpad1, Numpad2, Numpad3
normal size (decrease, reset, increase): Numpad4, Numpad5, Numpad6




There is still room for alot of improvement. I havnt made support for reflections or specular. But i think this is decent enough for an RTS.

The lighting looks realistic and the water really reminds me of a lake during a cloudy day.  I think the one thing to improve is that it looks funny having the waves be much larger than the base water texture.

I changed the diffuse texture, to more of an ocean texture.

if you place the light higher in the sky, it should look more like a day time scene.

I only got a crappy MMX card so it's no real surprise...

[bobjob]

yeah sry, it uses shaders, and a few textures in one pass.

seems like your hardware can only handle two textures when multi-texturing.

As its just a demo, I didnt make a low quality version.

I should have put specs in the original post.

[lhkbob]

Much improved, I like it

[Eli Delventhal]

That looks great. It really looks 3D.

[bobjob]

Cool, thanx guys for all the feedback.

time to get this working in game 


I also put in some more error handling, checks if your card can support the demo
also,
if you press "ENTER" it will uncap the vSync, if you would like to know your max frames per second with the shader.

500 fps on ati hd 3650 , 512mb 8x agp , not even pci-express, i think all java 3d games should include advanced shader and mapping techniques  to show that it isn't that slow compared to cpp as the impression generally is.

Did you press enter? I got 66.666667 fps with vSync.

Wow, 2200 fps steady on 1.8 ghz single core AMD 3000+ and 8800GTS 320 mb

38 fps on an Intel 82915G running Windows XP

450 fps on my laptop (Duo T8300, GeForce9500M GS, Windows Vista)

[ManaSink]

Oops, I don't think it was happy with my desktop setup, it ran in the lower left corner of a frame that spanned both my monitors.  I assume your demo was dedicated fullscreen?  If anyone else runs a nvidia card dual screen on linux, I'd love to know how did you set up you X11 conf file...

Nice effect man, looks really good.

Macs JRE default behaviour seems to store load images in Integers rather than 4 Bytes. I have tried to fix the problem hopefully it works now.

In XP 32bit i'm getting ~3000fps on a Q6600 with sli 8800gtx; though presumably it isn't using both cards.

:edit:

hang on i'll try forcing sli on to see if it makes a difference.....

:edit:

Nope, no difference - except SFR mode that caused it to limit @ ~600fps.

Ok, enough willy waggling 

[bobjob]

I tweeked the program a bit, so there is a decent performance increase.

Sorry to say if you run the program now, yours stats wont be a proper comparison to the other results previous to this post. Just thought Id give you a heads up.

74fps on my Acer Aspire One!

Tbh i'm surprised it even ran; for a moment I thought it hadn't, as the window was full of garbage for a few seconds while it was loading.
What looked like the residual contents of either the screen buffer or some textures in vram.
You might want to put an explicit clear in there somewhere, to accomodate shoddy Intel ogl drivers (GMA 945)

Interestingly, vsync did not function correctly, when eneabled the fps was fluctuating at ~61-62fps.
Can't think of an explanation for that behaviour =/

its possible the video card doesnt support vsync in window mode, ands its falling back on the timer sync method.
edit: Or your desktop frequency is higher than 60hz

[Abuse]

Just used GMABooster to up the clock of my graphics chipset to 400mhz (it's underclocked in the AA1 to reduce battery drain & heat output).

In this synthetic test it boosted the fps to ~104fps!
Definitely a gpu-limited test =)

It works now, and looks extremely good

sweeeeeeeet!
Iv seen that error before and im so glad i actually found a way to get rid of it.
