Hi all,

First, if you want to see my local field, you can download it from here:

Skokland model flight site in Haugesund, Norway

Create a folder named "Skokland" under Reflex/Umwelt/Wlp, and extract all the files to this folder. Then convert S1.jpg to BMP, and start Reflex.

You'll see that you can then choose between "Skokland1" and "Skokland2" from Reflex. The starting position is different, and the latter has a better and more realistic lighting.

I have hacked the wlp files to change the sun position and elevation, but I haven't found the "diffusion" factor yet. In "Skokland1" the shadow is too diffuse, in "Skokland2" it is sharp as it was the day the panorama was taken.

I've just been using a hex editor, but I might make a small software to allow you to change these parameters in your own sceneries if there is demand for it. I also know how to change the default wind strength in a wlp file, but I haven't been able to change the security zone yet. Nor do I know how to change the size factor of the model, so for the most part the model gets too small too fast when flying away. This is unrealistic and annoying.

Further, this panorama was created almost without any manual labour. I'm using PTGui and the latest version of "Autopano" that works as a plugin to PTGui. If you have good images and sufficient overlap, Autopano will be able to find a huge amount of control points. In this case, I did not touch a single control point manually!

You will have to experiment with the parameters to Autopano, but generally I have found that if using "/size:2048 /keys:10" (without quotation marks) in the command line arguments box to Autopano from within PTGui, it will do a very good job at finding and adding control points for you.

I would also STRONGLY recommend that you download "Enblend" and add that to PTGui. It is a bit slow, but it blends the images perfectly every time. Just remember that you have to choose TIFF as the output format in PTGui.

The "Skokland" panorama is taken with a 15mm lens on a D100, and consists of 10 images in two rows.

I'd be pleased to have some feedback if you try my scenery, or other comments to this thread.

Regards
-Øyvind

Hi, Could you post the offsets and details of what to edit etc in the wlp.
I spent some time on this a while back.
Best Regards

I'm in the process of creating a tool to do this. I'll probably release it later today. I'll create a new thread for that.

haaha NOW you tell me!!!

after i've spent an OBSCENE amount of time setting control points... 35-40 per overlap with up to 60 images!

Please explain more about the autopano program.... is it free? easy to use?

Cool that you figured out the hex!!!!

I've adjusted the suns angle so its perfect... but i did this by choping and re-centring the image so it matches the WLP i used.......

Keep at it mate.. adn thanks for sharing!

Yes, autopano is free:

http://autopano.kolor.com/

Enblend is also free:

http://www-cad.eecs.berkeley.edu/~mihal/enblend/

I haven't used the latest version of Enblend, but it probably hasn't gotten worse in any way..

Both work as plugins to PTGui. Search around and you'll find tutorials.

As I wrote in the initial post, I have found that using /size:2048 /keys:10 gives me good results with Autopano, but YMMV.

My tool for editing some interesting params in the .wlp will be released soon... :-)

Please tell us how you made any sense of the wlp file with a hex editor?

Please..

I have now released a tool that can help you change some parameters in the wlp file. You can find the details in another thread.

When it comes to the hex editor stuff, it is most of all extremely time consuming. For the most part it is trial and error. Change something (more or less) at random, and observe the effects in XTR.

In some cases you can search for known values (wind force, for example) that you can see from within Reflex. This may or may not work, since floating point values are a bit difficult to search for. If you know low-level computer stuff you know why.... If not, better use my tool...

Basicly, you need some computer skills, some experience, and a LOT of time.
