Hi! While discussing with SteelStyle on IRC,
dunno how we came to the conclusion to unite our skills to make a demo looking like this or like this!

Who knows how long it will take. Might be long for a single person. Not to mention we all have our own side projects. One sure thing this project will see its end! Let's see what August will produce

If you want to participate let us know here or on IRC. You can use free content if its license allows for it.

Here is the up to date TODO list.

MODELS
Some of the models need LOD I'll show you how we handle it.

CODING

Loading interface (DONE by kat)
code for LOD (DONE by kat)
GUI benchmark button

As we speak it looks like this.

The Sky is just a skybox, isn't it?

I tried to make some "believable", animated random clouds, but they look more like cotton...

You are welcome to post a picture of your sky, if you have one.

hopefully you'll get better results...

very nice. It'd be cool with a skydome having a gradient texture from blue to pink. This and your clouds layer would be perfect.
Do you want to integrate your code into ours, or prefer to send an example of use so that I include it directly?

It is a gradient, light blue to normal blue;)

I can give you my code, but.. its not the best cloud system. Maybe you can try an ICloudSceneNode. There is some code for it in this board.

Do someone know some good application for terrain editing/making with highmap generation? Would be usefull for this and many other projects

Terragen is the best one, I think. Its renders are photorealistic, so the heighmap should be fine;)

Hi, Just used it quickly to create a skybox. I created a flat landscape and covered it with water and used a sky that could be similar of your picture.

Resolution: 6 pictures for the skybox at 768 pixels X 768 pixels (The version of Terragen I have don't allow higher than 960 pixels)

Your forum is in french

Don't understand it clearly.

Just tried terragen 2.0.3.1 and must say it's hard to understand but not impossible.

+ for terrain painting option.

Hi, This is a skydome version made from the skybox (used 3DS and an idea by using baking)

m_krzywy, The files are hosted on my own forum. You only need to click on the link to download the file. Is there something else happening? (You shouldnt be redirected to the forum but download ONLY the file)

Christian is in! Nice website BTW! For your pretty dome if you want maximal image resolution may I suggest not to use not a full sphere (2.f), but 1.3f like this -to gain polies- so there's no need to show the sea on the sky image since the sea is a very large plane which goes till camera FarValue and will cut the skydome somewhere where Y=0. You'll gain pixels for the height of the image if you see what I mean. Makes sense?

My boat render : <300 poly

I once used a cool trick with terragen.. I first render a skybox without clouds, then i render another skybox with black sky with clouds. (and sun turned off)
Then, i make 2 skyboxes in irrlicht, texture the first skybox with the skybox texture that has no clouds, then texture the second skybox with the cloud skybox texture and set the material type to transparent additive (or something like that) and add a rotation animator to the clouds. It looks pretty neat

After 3 days of development we are here
we have a zip somewhere containing a demo and its source code.

click to enlarge

the palm. As of now the whole model is transparent,
Going to make it so that the trunk is not transparent and have a normal map.
Textures are ready

Trunk textures are tileable vertically.

However some transparent parts will be attached to the trunk :

They are both in the same file because they fill well a 256X512 texture
it will be a tga with an alpha channel.
And these tranparent polies will be removed by LOD, as well as the coconuts.

The result should be something like this

For the palm texture, no wonder why it looks bad in realtime here
is the actual one:

The shape of the palms will be made high-poly, too. Perhaps the diffuse map should
be created from a mesh to get it exactly how it must be... It's hard to find a photo
of just the palm.
