'lo, I just finished a demo: http://members.rogers.com/ramrajb/Downloads/NaturalEffects.zip Its kinda intended as a cure for insomnia - since I couldnt get to sleep at least my avatar can... ;) Thoughts, comments, and bug reports greatly appreciated :)

As always take this as constructive critisism, I mean nothing mean by what I say ;)

Few problems I saw:

1) The skybox didnt exactly match up so you can see the edges
2) Water and plant movement is way to fast, feels like im watching a timelapse film the way the waves move so fast along the island.
3) When I move the camera around I see a weird line thing in the water at a certon point, ill post a SS if you need me too.

Good work!

nice but there are some obvious errors in it, that not the previous writer noted.

1. the bilboarded Zzz:s sort of z occlude each other, it looks bad, drop the z-writing there.
2. what's up with the funky mouse controll.
3. the leaves are allso occluding eachother, might i suggest alpha testing.

Thx guys :)

- I'll see what i can do about the skybox...not sure why it looks like that
- I'll also add a time based update to the natural effects
- The line thing is kinda intentional - its a result of the sphere mapping - i'll see if i can find a better texture

- For the leaf and z textures I use the the ipicture indexed alpha method. For some reason the polys still obscure each other even after I make the depth test read only...any ideas?
- Can you explain what u mean by funky mouse control?

well since the view angle is based directly on the screen coords you can only rotate the view(left and right) around 360 degrees(most applications of this sorts alow for infinite rotation), and up and down is allmost non existant.

A way to solve this is to rotate only when you press and hold one mousebutton and then rotate the scene relative to how the mouse moves.

About the alpha testing, my guess is that it dosn't work(it could be set up with the wrong parameters) or could be deactivated just before rendering.

the correct way to do it on is to activate it just before and deactivate it just after the specific object you want to render with alphatesting.
One more thing, to reduce pixeliness of the leafs when doing alpha testing you could increase the resolution of the texture.

Looks nice.

In general I have same problems as others (to fast,...).

Your water also seems to be a bit unstable, as sometimes I can see big spikes out of it.

About the "line in the water". I sugest you use bigger but very blury/smooth texture.

For skybox: are you setting right warp modes? (clamp/clamp_to_edge)

k,

I fixed a few things. I added alpha testing(lol, i forgot to glEnable...), fixed that wierd line thing (has to do with the normals I was using), increased the viewing angle, added time based update, changed the texture for the leaf, and fixed the messed up skybox textures - it was the textures that were off.

Thx for the help nd tell me what u think :)

it looked pretty cool to me, the plants were a bit fast, but te waves seem fine, I am using a slow system though.

The mouse controls are still abit weird, but other than that it ooks good

It's a good demo !

But maybe you could add some "decoration" under water, some relief, and an underwater flora (like fish, everyone love cute little fish)

Another option you could add is ... *Suspence* ... *More suspence* ... Music. Like a soft relaxing music gently following the wind ?

With that, you could have a nice screensaver like Daveperman said

What's the reason for limiting the mouse mouvement ? would not it be better if we could circle aroung without limitation ? :)

Sincerly,

Karl.
