*** Bend Solution/Plugin Needed

[Urnemanden]

Hello,

I am often drawing maps of my track ideas and I recently thought of beginning doing that using Paint.NET. Unfortunately I have only found it possible to do maps with curves if I draw my maps black & white without any use of textures.

Above you can see/download a picture of how long I've come with my straight line. I have been trying a few plugins such as Bulge & Powerstretch, but the results didn't come along as I wanted them.

If there was a way to Bend the line a way so it ended up like above would make things easier for me and probably for other people too. An example of how that could look like will come up, if needed.

Additional explanation/screenshots would help.

It's not clear specifically what is needed.

[Urnemanden]

- Angle

For choosing how much the image should be bended

- Distortion

For how much the image should be distorted between top and bottom

- Focus

For locating the root of the image (The bend starts from here)

[APShredder]

So all you want to do is bend a line, right?

[Urnemanden]

Bend could be used on an image aswell. But if you want to keep it simple, APShredder, yes I want to bend a line.

[APShredder]

You do know that you can bend the line after you draw it, right? :wink:

[Urnemanden]

You do know that for me it sounds like you didn't read exactly what I am requesting? :wink:

[APShredder]

I guess I'm not getting what you're saying. From what I understand you just want to be able to make a curved line.

[Sarkut]

You want a plugin with repeatable results, not a work-around.

[APShredder]

Ok I get it now. I didn't realize that you wanted to be able to reproduce the same results over and over. Thanks for clearing that up Sarkut.

[Urnemanden]

I am still unsure if your getting it or not. I'll show you what I mean by theese 2 pictures:

Here is my test image which is an image of a tree in the middle of the jungle.

Now, I would like to bend this image 90 degrees to the right. Since the picture will become smaller because of canvas size I expanded the sides to the left and to the right (unfortunately forgot that at the bottom). Here is my result after "bending" it.

This is what the bending plugin can be used to mainly. It took me about 30 minutes to modify the picture to be bended using 7 layers, a calculator and Rotate/Zoom. Therefore I request a plugin to avoid the long time it takes if I wanted a 100% round bend for my image.

[APShredder]

I get what you're saying, but unfortunately I probably don't have the knowledge to make a plugin like this. I think it would require some sort of Trigonometry or other advance math that I don't know. Sorry.

Have you tried PowerStretch?

^^ Right there simon

Oh. :oops:

[Curmudgeon]

if your road runs horizontally, you could use polar-transformation (transform rectangular to polar)

then it would be a matter of cropping off what you don't need

similar to the process used in this tutorial

[Urnemanden]

The best result I can get using Power Stretch is this:

EDIT: I tried Polar Transformation, Curmudgeon, but the workaround won't give me precise result and a straight brush width yet.

I haven't succed yet in finding an effect which is faster and better compared to my manually 7-layered bend for my other example image, so I guess I am asking for some sort of plugin here. Posted another image below:

Multibend could be a suggestion too, so small distortions could be applied to the line without it changes width or gets stretched some way.

[Sarkut]

It's definitely difficult to avoid distortion, especially in terms of the texture.

This is the best I could do.

Edit-- Polar Transformation curves.

I must admit that you've got a better result than I did, but personally I would find it pretty hard to do an exact 90 degree bend using Power Stretch.

[LJXD]

Try a plugin called TubeOblique. That gives you some pretty nice bends

[Urnemanden]

Could you post me an example, LJXD? I am only able to get 180-like curves, thickest in the center and thin at bottom and the top of the image.

EDIT: I updated the plugin example, inspired from the Tube oblique plugin and from my own mistakes at my manually 7-layered bend.

[KillerK]

that the kinda thing your going for?

[Urnemanden]

Yes, but with a straight alignment at the root of the bend.
