I'm interested in converting a large vector graphic into an equitangular image. I'm looking to create an interactive 360 view in an AFrame project much like this one https://aframe.io/examples/showcase/sky/.
I've tried a plugin for photoshop called Flexify 2 but not having any luck. I'm open to different workflows or ideas on how to do this!
Any help would be greatly appreciated!

I am building a map navigation for a client and am stuck! I have built the map using and coords and all is fine. However I now need for each region to change colour when you hover over it.
I have done this before with simple sliced-up PNGs in Photoshop but because of the complexity of the map and overlapping items this isn't an option. I don't even know where to start - have tried some different tutorials and a lot of googling but can't find a good solution.
Here is my map so far: http://www.wiredcanvas.com/uploads/map/map.html
I want it so that when you click on a region it will turn a different colour - and I may also add a tooltip if necessary.
Any advice or help as to where I should go from here very gratefully received!!
Thank-you in advance

I am developing an application for viewing images.
I used the example of PhotoScroller Apple to implement this application.
In my application I want to be able to draw on the image.
I had the idea to put a UIView on top with transparent background and draw the lines via touch events. This solution has become very slow because the generated images are very large, around 3700x2000 pixels.
I also tried a solution with the example of Apple GLPaint that uses OpenGL, but it has a size limitation of 2048x2048 pixels.
Anyone have any idea or example of how I implement this?
I think you should try and tile your image.
One option is using CATiledLayer. Have a look at this short tutorial.
Or you could try and use CGContextDrawTiledImage to get your stuff done. Possibly this post from S.O. could help you getting started.
I'm working on a small image processing project in MATLAB. I have worked with MATLAB before, but never created a GUI. The GUI I want to create could be pretty advanced, so I need some hints on how to get started.
The purpose of the GUI would be to load an image and have it shown to the user. The user then has to click on two points in the image, of which the coordinates are stored (in pixels) in a variable. If possible, a colored dot is shown where the user has clicked. After the user finished with the current image, he can load a next one.
I have some experience with Java, and I think this wouldn't be too hard in Swing. But MATLAB seems like not having the purpose of creating such an advanced GUI. However, the whole project until now is in MATLAB, so it would be nice if I could manage to do it. Any help? Hints? Things I should look at?
Thanks a lot.
This is not a very complex task to be done in MATLAB.
For simple instructions about adding a picture to a GUI, take a look at this post:
http://blogs.mathworks.com/pick/2007/10/16/matlab-basics-setting-a-background-image-for-a-gui/
For instructions on various interactions between GUI axes and the mouse pointer, check this video (keep in mind that your picture in the GUI lies within normal MATLAB axes):
http://blogs.mathworks.com/pick/2008/05/27/advanced-matlab-capture-mouse-movement/
In general, Doug's tutorial videos are great for MATLAB beginners, and I'd advise you to take a look at more of them.
I have many images to display and do paint on them. I want to use axes objects in the matlab gui for individual images which should off course be scrollable. I dont know that how to create axes objects for individual images programmatically. Second is that I wanna create only one callback for all of them. I am wondering if someone can really help or point to some link as I did not find any good information.
Thanks

Hey guys. I got two images from video frames. They have a certain portion of overlap. After warping one of them, I'm currently trying to blend them together. In other words, I would like to stitch them together. But I don't know how to accomplish that. Can anybody please give me some help? Thank you!
Let's say the image data is store in 'image1_warped' and 'image2'. Appreciated your help!
The keyword here is Image Registration. The Image Processing Toolbox provides some functions for this purpose. The documentation has a some of demos as examples.
Checkout the blog post: Blend images with MATLAB,
with nice examples, and the MATLAB code.
Where the two images join apply the Photoshop clone tool (vary the percentage of opacity and size as required)
