Awesome stuff! I think many ppl can use it! You've got some nice shadows in there As from what I can see from the shadow artefacts, this shadowing stuff reminds me on something

First small bug: The default file name of the open file dialog is "openFileDialog1". You may want to blank this out

Another hint: To fix this "eye catching" seam:



You can use my clamped ESM code I presented here: http://www.truevision3d.com/forums/showcase/source_library_sample_parallel_split_shadow_mapping_that_you_can_reuse-t18798.0.html;msg129548#msg129548

Code:

#define ESM_K 50.0f // Range [0, 80]
#define ESM_MIN -0.5f // Range [0, -oo]
#define ESM_DIFFUSE_SCALE 1.79f // Range [1, 10]

// Exponential Shadow Mapping
inline float ESM_GetShadow(
in sampler2D depthMap,
in const int splitIndex,
in const float2 uv,
in const float receiver)
{
    float occluder = tex2D(depthMap, uv)[splitIndex];
float shadow = saturate(exp(max(ESM_MIN, ESM_K * (occluder - receiver))));

return 1.0f - (ESM_DIFFUSE_SCALE * (1.0f - shadow)) ;
}

If you do not want to scale your shadow among a certain factor, simply return "shadow" instead of "1.0f - (ESM_DIFFUSE_SCALE * (1.0f - shadow))".

Thanks for the compliments and I'll fix that bug soon.

And the shadows are all thanks to your PSSM example and all your help getting it looking nicer. I could probably tweak them more to get rid of some of the artifacts.

Have you been able to fix the projection code? I have found out that it becomes unstable with light directions where one component is 1 and the others 0, like [0, -1, 0]. This is where the dot product screws up. A crappy solution would be to clamp it to |0.999999| or something.

[Toaster]

hmm I don't think my light direction ever reaches a 0, -1, 0 stage. Its all calculated via zak's sky shader and it always spits back directions that are like: .9255235325, .3251326, -.235235235 well you get the idea.

I cant seem to download the file successfully.
Tried 5 times and it always ends up damaged (and a different filesize).

Something wrong with your host?

[Toaster]

Yeah there appears to be a problem with my host either that or my download script.

You can download it here at:
http://treegen.pipedreamgames.com/downloads.php

Edit: I noticed a bug in my php download script it should be fixed now.

I hope this helps!

Well, that worked out nicely! Great stuff.

[Raul]

Thank you for this amazing tool.

[zwiglm]

Wow. Thx for the cool work.

A few days ago, I was thinking about asking "West", what happenend to his Tree Generator.

Cheers,
Martin

[zwiglm]

Erm. BTW... any chances for the source?

*greedy smile*

Cheers,
Martin

[Toaster]

Sorry there will be no source. Eventually I plan on releasing a .dll you use. It will either spit back a TVMesh and TVMiniMesh or the vertices. It will also support LOD and other such things.

I think the next weeks will be a great time for all botanists in the forum 

Good work Toaster.

[Toaster]

Thanks WEst! Thanks for all your help with the trunk generation too Once I get around to making an about box your name will be in the credits for sure!

Woah. That would be great. ...and very generous.

[Shargot]

great work. but why your trees (export to tvm) Such slow? in my editor if i place 10 your trees fps drop down from 200 to 45 (( with my trees The same situation at 100 trees with the same face and vertex count. not optimized geometry? and in your editor very low fps

[Toaster]

Your tree's that you are exporting probably have a high poly count. I would suggest lowering the poly's by either:

A. Lowering the Tree's sides.
or
B. Use less depth

You can also use less leafs in an effort to lower the poly count. If you have low FPS in my editor I suggest turning down the settings and if you have the shadows off and the grass off and your still getting slow downs then I recommend getting a new GFX card. I have a geforce 7900 gs AGP 8x that can achieve 40 fps with Medium settings and 60-70 fps on low and with everything off I get around 120-130 fps. For a geforce 7900 gs this is good for my app. With my nvidia GTS 250 I get well above 100 fps with the settings on high and on Epic High I get around 60 fps. Epic high is really only for the best systems out there(which my CPU is rather old so it doesn't run epic high like it should).

Another thing you can try is to not have multiple windows open. Mainly stuff that uses alot of CPU power or GPU power. In example I wouldn't recommend running your editor when my tree gen is running. Really though this editor was designed to create next gen tree's and not low poly trees.

Very nice Toaster! Do you render the trees with each leaf quad billboarded to the camera because the exported files viewed in ModelView don't look quite as good

[Toaster]

Tree Gen v1.1 has been released!

http://treegen.pipedreamgames.com/

Some new features have been added as well as some bugs fixed. Here's a list:

Features Added:
==================================
-Day Night Cycle.
-Wind added for the leafs.
-Volumetric Lighting
-About box
-Help File

Fixed This Version:
==================================
-Trunk options not scrolling when needed (Auto scrollbars set to true).
-Generate button disapearing when window is resized. (Not Anchored).
-String localization errors (Fixed).
-Volumetric Lighting Settings did nothing (Added tree leaves to the VL rendering).

You can download the newest editor from the Download Section of the website:
http://treegen.pipedreamgames.com/downloads.php

Enjoy! 

Very nice Toaster! Do you render the trees with each leaf quad billboarded to the camera because the exported files viewed in ModelView don't look quite as good

The leafs are minimeshes that are axis aligned to the camera. If you wait till the dll is released you will get this as well as dynamic LOD and generating trees on the fly. Plus a little shader with wind.
