I was wondering if there is a way to combine multiple captures using either the ipad app or desktop application for 123D Capture through Autodesk. I want to take a capture of an object, flip it, take a second capture of the bottom of the object, and then combine the two captures so I have the entire object captured from every angle (top, bottom, sides).
Ideally after this I would see which sections of the object are blury and take new photos of those sections and manually stitch them on.
Thanks for any advice.
Check Autodesk ReCap, it can manipulate & handle point clouds
http://www.autodesk.com/products/recap/overview
You can go even further to generate 3D models from these pictures with ReCap 360( http://recap360.autodesk.com). And it is also possible to do this with API, here are some samples on github (http://developer-recap-autodesk.github.io/)

I'm playing around with the Autodesk forge viewer and adding custom elements, like it is done in the Autodesk's scene builder example.
I am looking for a possibility to set the "visibility" of one of the new objects - e.g. when moving around the camera, the green cube should remain on it's 3D-position but should not be occluded by any other object (like it is somehow in blue with outline when it is selected). Or maybe even better: if it is covered by another object, it should shine through (with configurable opacity).
Unfortunately after discussing with Engineering it's not yet possible - will continue the conversation to see if we could come up with a workaround for the upcoming releases ...
Like I suggested in the comments try append your geometry to Viewer3DImpl.sceneAfter for the time being (which will be publicly documented and exposed as Viewer3D.sceneAfter in a couple of weeks) or an overlay. Then setting depthTest to false should do what you want...
The choice of sceneAfter or an overlay depends on how you want the objects to be drawn during progressive rendering. sceneAfter is only drawn once at the end of everything else. Overlays are redrawn for each progressive frame...
I wrote a tool which draws model curves on a view and adds dimensions to it. The tool when run locally on my computer it works fine, lines are drawn and dimension are added and visible.
But, when I upload the code to Forge Design Automation, the lines are drawn and dimensions added. However the dimensions are not visible. After I downloaded the rvt file I can see the dimension through Revit Lookup, but not directly on the view.
Any suggestions where I might be going wrong?
Here is my code...
mCurve.LineStyle = buildingLineStyle;
//Adding dimension
ReferenceArray references = new ReferenceArray();
references.Append(mCurve.GeometryCurve.GetEndPointReference(0));
references.Append(mCurve.GeometryCurve.GetEndPointReference(1));
Dimension dim = doc.Create.NewDimension(groundFloor, line, references);
//Moving dimension to a suitable position
ElementTransformUtils.MoveElement(doc, dim.Id, 2 * XYZ.BasisY);
Thanks for your time in looking into this issue.
Thank you for your query and sorry to hear you are encountering this obscure problem.
I have no complete and guaranteed solution for you, but similar issues have been discussed in the past in the pure desktop Revit API, and two workarounds were suggested that might help in your case as well:
Newly created dimensioning not displayed
Dimension leader remains visible after removal
One workaround consists in creating a new dimension using the Reference objects obtained from the non-visible one.
The other one, in moving the dimension up and down within the same transaction to regenerate it.
I have lately been working on Forge Reality Capture API and using simple curl commands to reconstruct some scenes from images.
The process goes through smoothly but I never obtain a complete mesh.
1.I have tried increasing the number of images about 5 times ( from 20 to 100)
2.Tried both the obj and rcm formats ( my scenetype=object)
3.I investigated the camera positions after exporting the rcm mesh to Recap photo and only about 15 positions are shown. While I used about 100 frames in several positions. Only the images from these camera positions are stiched and get an incomplete mesh.
Is this a algorithm issue in the reconstruction?
Do I have to capture more pictures? The area is relatively small, a corridor of 50m*20m.
Can I re-process the same scene by adding additional photos?
Is there a necessity for some amount of texture?
I am grateful for the answers.
Cheers!
I suggest having a look at my blog post on Reality Capture API https://forge.autodesk.com/blog/hitchhikers-guide-reality-capture-api that might help you to debug and identify the source of the problems.
The source of the problem could range from object having transparent or reflective surfaces, to your images (or some of them) not being properly uploaded.
In general, if you don't get complete mesh, the best solution is to take more pictures of the missing spots, instead of more pictures of the entire object. If there are missing spots, it means that the engine could not figure out of your images how to stitch them - more images of those areas should help.
I have a cabinet and I want to get the orientation of the cabinet. I want to automatically locate the front of the cabinet.I don't know how to get the orientation
This is a tricky problem.
Front is relative to something. If you have a cabinet, one can assume the Front is where the handles are. Now assuming the handle is a block (AutoCAD), or a family (Revit), or a part (Inventor), your code may search for such an instance.
From the above, search for this object, then calculate a vector from the center to it. That will be the base vector for a raytrace.
Okay, so I've been busting my hump the last week or so on this project for my OOP/AS3 course and this past Sunday I realized that my approach wasn't going to work so I scrapped the better part of it and started over.
Our assignment is to create an XML based flash menu that demonstrates an understanding of the OOP patterns we've just learned. It was kind of a 'test the waters' project where he gave us a ton of tutorials and information and told us to make our best attempt at making sense of it so I'm certain there are more efficient ways to do what I'm doing, but that's a moot point.
We need to employ at least two patterns in our menu, though at the moment I'm just focusing on MVC so that I can get the mainUI working before I finalize the second part of the UI. It essentially flows like so:
MainUI has 4 menus that slide out.
Each slider has 3 thumbnails on it.
Clicking on any of the thumbnails will move to the next part of the UI. This functionality is currently disabled.
The program runs with 0 compiler errors, but the images are not being placed on the stage correctly and I can't figure out why. All the image paths are being pulled and stored from the XML properly. The main background image is pulled once and is supposed to be only placed once (if statement that uses a count to determine whether to run the placement function or not), but it is being placed 4 times with the sliding menu image. The sliders are being placed in the correct positions (switch statement that iterates through the mainUI function in the View class and creates a separate loader for each one), but the thumbnails are not all showing up. So here is what I'm seeking help with:
The mainPanel image should only be placed once, rather than 4 times with each slider.
The sliders, while being placed correctly, must be tweened in different directions through the as (using TweenMax), but each instance is unidentifiable from the other so right now they all have an eventListener that calls the same tween method. How can I distinguish them in a way that lets me apply a different tween to each (This will likely be a concern with the thumbnail functionality later as I will need to load different XML data based on which thumb is clicked).
I have added what I hope are very informative comments to each script so hopefully people can help. Also included are images of what I want the mainUI to eventually look like and how it's coming out currently.

top image is how the stage is outputting, bottom image is what I'd like to to be - http://imgur.com/a/bOmsS
Last quick note, stage is currently set to 600x480 with a black background. Ideally, to reinforce OOP principles, our professor wants us to avoid using the timeline or library if possible.
Any advice at all will be greatly appreciated! Thanks!
Install FlexPMD This is a very good add on( sometimes hard to install ) It basically is used to show areas of your code that you are not following standards. For example your classes lack the use of "this". And you should avoid passing parameters in constructors. It would be good practice to develop standardized writing skills while you are still new.
Looking at your code I see you are calling buildUI from within a loop.
buildUI is assigning a MainView object to mainUI.
So each time you go through a loop iteration you are reassigning mainUI.
In the end mainUI will only be the last iteration of that loop.
Not sure this is your issue but is an issue.
[EDIT]
Excellent Singleton guide for Flex SDK
Part 1
Part 2
Some Good writing on pure AS3 Singletons.
I would prolly start from scratch as your XML data is miss formatted.
your XML should resemble something like this.
<MainProject>
<MainUI>
<Thumbnail Name="Spring">
<Destination Name="Spring" Price="99" ratingPath="images/SP1/SP1rating.png" />
</Thumbnail>
<Thumbnail Name="Winter">
<Destination Name="Winter" Price="152" ratingPath="images/SP1/SP2rating.png" />
</Thumbnail>
</MainUI>
</MainProject>
Then you should have the following structure on your stage. These movieclips should be empty and already placed inside on your stage with instance name.
Stage
MenuUI MovieClip
ThumbNail1 MovieClip <- feed it thumbnail from the XML
ThumbNail2 MovieClip <- feed it thumbnail from the XML
ThumbNail3 MovieClip <- feed it thumbnail from the XML
ThumbNail4 MovieClip <- feed it thumbnail from the XML
This might be a bit too vague, just tell me if you need more details.
Hope this helps !
