Water Spikes

Guest · Post by **Guest** » Wed Jul 14, 2004 5:49 am

I have added water to my game but when it washes up on terrain it looks awful, sort of spiky:

Any idea on what I can do to fix this?

Sorry for the double post but just to show more on this problem, here is it zoomed out:

Does your water texture have very many polygons or is it just one or just a few. If not try a higher polygon model for the water.

My water texture is just an image..it doesn't have polygons. What do you mean?

thesmileman is probably thinking that you used this: http://irrlicht.sourceforge.net/docu/cl ... er.html#a6

Yes I was think that you were using the addWaterSurfaceSceneNode() function ass DarkWhoppy suggested

I would think using a mesh would be more benificial if you are planning on doing any sort of detection of whether someone is in the water or not or collision detection but to each his own.

Is your image at all transparent?

You might try a higher resolution image and not making the image larger than it's original size

Have you used scale to make the water plane larger ?

i had had the same problem some time ago

i make it short ! try to run your application in windowed mode then there will be no spikes!

see here!

i think it has to do with the z buffer! somehow the fulsceen use a different amount / precisely z buffer .. so the rendering goese false. don't know how to increase the z buffer accuracy.

maybe you guys

I have noticed that skyboxes and other textures often times are not a sharp in fullscreen mode as they are in windowed.

After I changed it to using stencil buffers it works fine! Thanks a lot
