From this program, you can access your 123D Catch projects as well as more than 10,000 models made by other users. On a computer, download and install Meshmixer, another free offering in Autodesk’s 123D Catch family of programs.
“This finalizing bit can be somewhat complex, and usually we see folks get hung up here if the project gets really huge,” says Christian Pramuk, Autodesk’s product manager for 123D Catch. In the cloud, Autodesk will convert the photos into a full-color 3D object in the OBJ file format, texture it, and then convert the textured OBJ file into a streaming 3D model for display on your mobile device. Take 30 to 70 photos, the more the better, all around your subject and from above and below, with a lot of overlap between them. Natural light on an overcast day is usually best. It is best if you can easily move around your subject 360 degrees, although 180 degrees can work as well.Īdjust your lighting so that you don’t have sharp shadows. Make sure it is not transparent or reflective.Ĭhoose the setting. Here’s how.Ĭhoose your subject-such as a toy car, a pile of laundry, or your cat sleeping. All you need is a smart phone and Autodesk’s free 123D Catch application. Now, you can not only view 3D models but create them yourself. The View-Master stereoscope that you might remember from your childhood was patented in 1939. In 1849, Sir David Brewster invented the first lens-based, hand-held stereoscope. It presented two offset 2D images separately to the left and right eye of the viewer, which the brain then combined to give the perception of 3D depth. In 1838, Sir Charles Wheatstone invented the stereoscope to give depth to images. In the 16th century, “binocular” images were viewed cross-eyed. Stereoscopic imaging, better known as 3D, is not new.
