What I had was a blurry mess of greyish and blackish fog on a stool.
AUTODESK 123D DESIGN ARCHIVE SOFTWARE FULL
I set it up on a stool, then rotated it around while keeping the camera still, and then I loaded the images to 123D Catch, expecting a full blown mesh of my antique camera. How wrong can one be? My first attempt at taking the 24 pictures was a shot of my trusty Bolex camera. Of course I thought that it doesn’t make any difference if you walk around or rotate the target.
AUTODESK 123D DESIGN ARCHIVE SOFTWARE HOW TO
How to use it?Īutodesk suggests that you take the pictures walking around your target and try to keep the camera at the same relative height. Autodesk has been very helpful in learning the process, by the way. While it’s always impressive to get one of those, it’d be way better to tell the user what really failed, and after discussing usability with Autodesk, we agreed it’d be better worded otherwise. I tried first with a webcam, and the process failed with the error message “general error”. 5 megapixels in the camera is the minimum for good quality, and it may happen that the app fails to work in case you try to feed it with low quality images. It is also possible to grab HD video of your target, but the resulting point cloud will not be as accurate as it is with hi-res cameras. After you have installed the apps, you’re good to go. If your phone works well, you don’t need the PC app, but it’s a good idea to grab one in any case. You also need an Autodesk account, which is free, and you can create it on the site while you download the PC app as well. At least with the Windows Phone, there is an issue with dual-core phones, such as my Lumia 920, so you may want to check phone compatibility. You can download the software from Autodesk, and there is an app for Android, iOS and WIndows Phone.
It is easy to import that into Blender and then modify it to suit whatever needs you may have – trim, add to another mesh, or sculpt further and then print. It is possible to edit the mesh in 123D Catch to a degree, but for my purposes all I need is the. OBJ even has material maps, so you can see a color model of your target.
With some 24 or more high-resolution photographs, you can get a full blown 3D point cloud, and that can then be exported into. Now that the printing department of the 3D Lab works well, with the 3 Minifactories and one CoLiDo Printrite, it’s time to take the next step.Īutodesk is really generous when it provides the 123D Catch software for free. I found a piece of software, Autodesk’s 123D Catch, and it seems to work really well with my pet project, the 3D printed 3D scanner system. I’ve been a little busy lately, what with the new curriculum at Haaga-Helia being introduced and whatnot, but I’ve also managed to do something I have wondered about for a while already.
