Overview of Capturing Reality Realit圜apture.
When the model is ready, move on to the Create a Model Target section in How to Create a Model Target from a 3D scan. Model from the Meshroom reconstruction process before and after model clean-up.
Meshroom Model Simplification and Realit圜apture Simplify tool. Please consult their documentation and practices on doing so. NOTE: Some aspects of model simplification can also be performed in the respective photogrammetry software.
Please refer to the Model Target Generator User Guide for information on supported file formats and general model preparation.
Use your preferred mesh editor software to prepare the model for the MTG. And lastly, the model should be re-scaled to match that of the physical object. The model might also be in such high detail of both vertex count and textures that it is over 100MB in size both should be reduced to avoid errors during the Model Target generation process in the Model Target Generator (MTG). Firstly, depending on the final set up of your reconstruction process, the model might include a surrounding mesh that has to be removed. Please see the Meshroom topic on Turntables and Realit圜apture’s discussion for more information.Ī model generated through the photogrammetric method requires additional editing. This approach is most suitable for small objects. NOTE: Alternatively, a seamless background and a rotating disk would allow you to reposition the object and in that way capture the object from all its sides, but the software will likely have more difficulty in positioning the images in its 3D reconstruction environment. Therefore, do not rotate or move the object while photographing it and make sure the background has enough detail. NOTE: Generally speaking, photogrammetry uses the background on the photographs as an aid to stitch and align each image together in a 3D reconstruction environment. It is better to have too many images than too few! Additionally, if the object is suitable, take images of both its entirety and of up-close details. However, depending on the size of the object, taking at least 100+ images of the object is recommended covering all sides and at different angles and heights. You can find their guides at Meshroom’s Capturing Guide and Realit圜apture’s Taking Pictures Guide. We recommend that you consult Meshroom’s and Realit圜apture’s own guides on capturing images that are suitable for their software.
NOTE: An activation step to verify your license is necessary when you first launch the software. The installation guide will appear in their application download menu and when you first launch the application.
