i have a sets of images A  Each image (a_i) is a slice of an huge computer generated map-image M_A.  Each image a_j in A overlaps with at least one other image a_k in A. There is no distortion, blur or color difference they overlap pixel perfect and are completely planar.   i need to stitch them together = map M_A. After that i need to find the difference between M_A and an other map-image M_B (gimp)   the last part is no problem: I can put them in 2 layers in Gimp an set one to 'Differece'  the tricky part is the lossless stitching  so:   How do i stitch the overlapping images together without blurring or deformation?   i tried Hugin () - i like it - but it seems it is all about inexact images (taken by Cameras). It forced me to choose a focal length. And after 3h of computation i ended up with a projection of planar objects on a sphere, witch were then projected back to a plane for rendering...

I can create a collection of pictures giving a 360-degree view from a certain spot, just taking a bunch of photographs from the same spot but in a different direction.  However, what software could I use (on Windows) to stitch these images together to get one big image?  I prefer something that would stitch them together without showing any seams.

I've been working happily with Blender all this week and last, performing hundreds of operations, many booleans, and getting good results in a rudimentary model for a small enclosure.     Today I've renamed the file to v2, and started to make a couple of changes.  I'm just removing some material using a simple shape to create insets and a boolean difference operation.  Suddenly, though, the 'difference' is behaving like a 'union' and vice-versa.  I thought I'd forgotten something overnight, and tried it on two other simple objects in the same design, with the same result. I then opened a new design with just two cubes and tried it there, where it works without error.  Quit, back to my own design v2, and still the behavior is swapped.     I've restarted Blender a couple of times.  Moving on to trying more renaming, rebooting tests etc.  Is this a known issue, am I missing something obvious? Is there a work-around that someone can suggest.   (I'm using ver 2.70 on Mac OS 10.8.5)

When I overlap 2 objects like this    resulting freestyle lines are like this    But I want render overlapped edge lines like this(red lines below picture)    What's the easiest way to accomplish my purpose?(A lot of objects in my work are made in that way so resulting render image misses many overlapped edges. I tried to remake some object to reveal overlapped edges but I realized that remaking all objects is too hard to me.)

Simple idea: I have two images that I want to merge, one is 500x500 that is transparent in the middle the other one is 150x150.  Basic idea is this: Create an empty canvas that is 500x500, position the 150x150 image in the middle of the empty canvas and then copy the 500x500 image over so that the transparent middle of it allows the 150x150 to shine through.  I know how to do it in Java, PHP and Python... I just don't have any idea what objects/classes to use in C#, a quick example of copying an images into another would suffice.

I'm a beginner at rails programming, attempting to show many images on a page.  Some images are to lay on top of others.  To make it simple, say I want a blue square, with a red square in the upper right corner of the blue square (but not tight in the corner).  I am trying to avoid compositing (with ImageMagick and similar) due to performance issues.  I just want to position overlapping images relative to one another.  As a more difficult example, imagine an odometer placed inside a larger image.  For six digits, I would need to composite a million different images, or do it all on the fly, where all that is needed is to place the six images on top of the other one.

I am wondering if there is a way to combine multiple images into a single image using only JavaScript.  Is this something that Canvas will be able to do.  The effect can be done with positing, but can you combine them into a single image for download?  Update Oct 1, 2008:  Thanks for the advice, I was helping someone work on a js/css only site, with jQuery and they were looking to have some MacOS dock-like image effects with multiple images that overlay each other.  The solution we came up with was just absolute positioning, and using the effect on a parent &lt;div&gt; relatively positioned. It would have been much easier to combine the images and create the effect on that single image.  It then got me thinking about online image editors like  and wondering if there could be a browser based image editor with photoshop capabilities written only in javascript.  I guess that is not a possibility, maybe in the future?

This is sort of an unconventional use of Blender, but I'm straightening the distortion of scanned pages of a book, and I have the pages of the book scanned and numbered. What I want to do is use a plane with a simple UV map (two faces, one for the left page and one for the right). I've tested this concept out and it works for a single scanned image. I'm thinking I can run the scanned pages as an animated image sequence. What I'm not sure how to animate is the UV maps. Any idea how I can have a different UV map be called automatically for each frame, corresponding to its number? Maybe there is some way to use Python to update which UV map is used in the material's UV node?

I wanted to photograph the full moon against a beautiful deep blue sky. I ended up with blown-out highlights of the moon:    So I switched to spot metering and captured the moon, losing the blue sky in the process:    I want a single photo that shows both the moon and the surrounding context (in this case, the blue sky). Doing an exposure fusion in Photomatix Essentials did not help:    Nor did HDR fusion (again in Photomatix):    Notice that the detail in the moon was lost in both cases, and the sky was also messed up in both cases: exposure fusion lost the beautiful blue color, while HDR created more texture than was actually present in the sky. I toggled Photomatix's option to remove ghosts, but that didn't help, either.  How do I photograph the moon together with its surrounding context (in this case, the blue sky, but in other cases, a tree, buildings, etc) without blowing highlights or shadows? I'm using a Sony NEX-5R, with the longest focal length lens I have, and with manual focus when needed.  Thinking I should fuse the photos manually, I tried opening the images as layers in Acorn, with the darker photo on top and with opacity set to 50%, and tried all 15 - 20 blending modes (normal, dodge, lighter, darker, multiply and so on), but none of them seemed to work. I'm afraid I don't know enough to use layers effectively. What blending mode and opacity and order of layers should I use for this task?  I don't have Photoshop, but do have Lightroom 5, Acorn and Nik Collection.  (In case you are about to recommend software, please note my requirements: I use a Mac, I would be willing to pay $20-30, and I don't want to use command-line software.)

I have a set of three images imported in Lightroom 3.6 which I want to stitch into one panorama using Photoshop's CS5.5 Merge to Panorama tool. As I see it I have two options in doing so.   Doing all modifications (colour, brightness, contrast, etc...) first, syncing the changes between the three photos and then stitch them together. Stitching the photos first and then use Lightroom to apply modification to the whole image.   Which of these two methods is considered to be best practice?

I'm not sure how to ask my question in generic terms, but here's what I want to do.  I have a 360°x180° panorama photo. I took the photo with an app (Google PhotoSphere).  Unfortunately my app doesn't save the individual photos I took, only the auto stitched panorama, with the "center" of the photo of its choosing.  I'd like to recenter, crop, reproject, etc. the photo, just as I would as if I had stitched individual photos into a panorama with a panostitching application like Hugin.  How can I bring a full panorama photo into Hugin (or similar software) so that I can manipulate the photo to my choosing?   My goal would be to export a new panorama photo (and not necessarily a 360x180).  Currently my only option is to view the photo in panorama viewing software, and take screenshots. However, this of course limits my resolution to my monitor, and only in the projection they're presenting it in.

I'm trying to work with an image in the VSE that is larger than the rendered screen and the VSE always cuts them off. So either they are stretched to fit the screen or (when using "image offset") they are cut and cropped. in the specific example I want to use a map over which I want to pan and zoom in, but not use the default camera-setup because I don't do anything in it anyway, just use VSE and strip modifiers. So how do I get blender to use the WHOLE image instead of just a cropped 1920x1080 selection of blank ocean?

I have a  which overlays Open Street Map data on imagery for Pennsylvania. As a baselayer to the roads (and eventually other layers) I have two baselayers - Blue Marble NG and USGS EROS 1ft imagery. I would like to be able to combine these two layers into a single base map object that switches automatically as the user zooms in since it makes no sense to view the 1ft imagery for the whole state or the Blue Marble imagery when you are zoomed in.   Ideally I'd like to do this on the client side as I'm pulling the imagery from two different sites.

I'm trying to fake a DOF effect for Sprites by using 2 cameras, one for the sharp objects, one for the blurred ones. I have set up the layers like Blur and Sharp accordingly.   So I have these 2 cameras, and I use Unity's Blur (optimized) script to blur things, and I have this script on only one camera, the one that is responsible for the blurred render.   I have the cameras like:  Cam 1:   Clear flags: Don't clear (this is the main, sharp cam) Culling mask: sharp layer has no blur effect (or any other post proc effect).   Cam 2:   Clear flags: don't clear (this is the blur cam) culling mask: blur Has Blur (optimized).    Now, if this blur cam is on the back, meaning its depth is LESS than the main cam's depth, I have a sharp player ground and a blurry background. However, I need a blurry foreground too that should be on top of the player ground.  The issue starts when I set the blur camera's depth higher than the main cam's. In this case, everything gets blurred, no matter that the main cam has no blur effect on it.   Question is, how to set this up so only the desired layers get the blur?

I need to create an image like this, but I do not know what software or technique to use. I tried to use the Mesh Tool in Illustrator, but the result is odd, also I tried to blur an image in Photoshop, but I need to use some particular colors.

I have 3 separate planes that are contiguous and have a common material.  I have applied a noise texture which I later want to use for displacement.  However, the noise texture shows up on the seams, it has clearly been stamped on each of the objects from the same origin point, as can be seen in the first image.    Is it possible to make this seamless?  For example, if I do the same thing with the wave texture, it goes across the objects seamlessly, as below.    Thanks

How are various maps such as diffuse, AO, cavity, or displacement imported into Blender?  I saw the Texture tab has import image, would you do this for all maps and connect them somehow?

I have a brick wall that I am trying to add a door to. I have already UV mapped it, so when I move the loop cut to the right height, it distorts my UV map. How can I avoid having to unwrap it again?
