Two requests packed in 1 thread .

1)I'm looking for info on RENDERING(not creating or modifying) spt(speedtree) trees.
To be more exact I'm looking for the algorithm to change those bezier splines in spt files into the final mesh ready to render.
It's for my oblivion renderer project( http://www.youtube.com/watch?v=3pC_Xgm7fLE ).
I'm stuck on rendering trees atm .

2)I'm in need of a mod with teared landscape to test a tool I made(a tool to fix tears obviously).
More than teared landscape I'd like this "test" mod to have some rock/object on it, I'm quite unsure of the inheritance/override of cell grups(I just exported the land and not the other entries, I may have to change that). If the teared landscape could be near the imperial city all the better .

Rendering project ? Do tell more.

As for the algorithm, I doubt that its freely available. SpeedTree is after all a proprietary software.

Tell more...like recoding Oblivion engine?
Ok now I sound insane so let's leave it at rendering project .

As for speedtree I know the algorithm is not freely available but I'm looking for someone who has reversed the algorithm(I had to ask if someone had done it before trying myself).

:drool: Dude, I've been dreaming of a mod like this... first I've heard of it. Good luck.

a very ambitious project, but i wouldnt say it isnt doable.

It's highly unlikely you'll find a single mod with land tears in itself. This sort of thing usually would only happen in a mod which has been cleaned in TES4Gecko or TES4Edit manually and a mistake was made.

You will however find plenty of land tears when loading two conflicting ESPs together at the same time. Take a look at my UL Compatibility Patches page on TESNexus, it lists a number of conflicting mods, many of which include land tears in the conflict. If you were to take those conflicting mods and NOT use my corresponding patch, you'll get land tears!

But if you NEED the tears to be in one ESP, you could always merge the conflicting mods together, that should create a single ESP with land tears.
Another alternative would be to take any mod with heavy landscape reshaping, and remove some LAND records. This would also produce land tears along all the cell bordering that removed record.

As Vorians said, easy enough to generate tears if you need them. However, if you want one that's already got them in its own ESP, grab Verona House Bloodlines. They haven't uploaded the repaired version of that ESP yet.

I have to admit, I'm curious to see just how this would get solved. It sounds like all you're doing is generating a patch ESP that fixes the issue?

My program parses all the esp currently active, unpacks the VHGT subrecords(heightmaps) of all the LAND, comparing each cell to the 8 adjacent cells, starts by checking the 4 corners(since they are shared by 4 cells each they have to be done first), do an average of the 4 points if they differ and change the 4 points(1 point per cell...) to the new average. Then it compares each cell to the directly adjacent(left, right, up, down) and basically do the same but for each of the 33 points they have in common. It then repacks all the heightmaps modified and write all the land records modified to an esp file.

Currently it's very slow(around 3 minutes to check everything) but I'm in the process of recoding my tree manager to simplify things(I coded the first version not knowing much about the actual structure of esm/esp files and so it was badly designed, should be 3-4 times faster once I'm done, yes it was very badly designed ).

Interesting. It sounds a lot like the process I sometimes do now by hand to remove unwanted height edits from landscape data. It's very tedious to do that in tes4edit and doesn't always work for whatever reason, but it has allowed me in a few cases to chop cells out of mods that otherwise would have to keep the unwanted edits.

If you're complaining about it taking 3 minutes to process, don't worry about that. That's nothing. Unless the inefficiencies are really bad for the outcome of course.

Recoded the whole esm/esp parser thing and now it's blinding fast, takes like 10 seconds to check everything.

Though it finds more tears than expected .
Maybe I shouldn't floor the average hmm, I will check...

For those curious, here's the result on my modlist(60286 cells):

edit:
Doesn't codebox work as on the old version of the forum? o.O

Are you going to release the source or is it going to end up like TES4Edit?

I will release the source when I'm satisfied with the look of the code .

And darn it! I just realized I messed up the FormID management!
I was about to release it too! And bam it hit me that I had completely messed up this part... :banghead:
Anyway that probably explain the numerous tears detected, cells set in wrong worldspaces probably...

Hopefully I will end up getting it right before the end of the week .
