At first glance new technologies can provide an engaging way to interact with a subject which may induce a meaningful learning, but it soon falls short when it becomes common or even repetitive. As this new technology becomes natural to the user, it no longer relies on novelty and goes into another condition, as a tool. The use of Computer-Generated Imagery (CGI) experienced exactly this, decades ago, but as it's constantly being iterated upon it needs to be reassessed often. As CGI goes, the tridimensional imagery as an overcomplicated format started to fade, as new hardware and concepts made way into everyday objects such as smartphones, webcams, cameras, 3D mesh generation apps, etc. It's use for museological purposes became clear in the field of cultural heritage for archiving and communication. So, to verify the viability for a low-cost and easy to use solution aiming to novice users, different types of non-destructive methods surface based reconstructions are analyzed to identify the quality of the resulted mesh based on precision, traceability and compatibility. To this end, it was proposed a method with a set of metrics which can be used to point out the usability of a reconstructed object for a specific end. Four archaeological artifacts were scanned using the video photogrammetry method and the depth video method, to be compared with a laser scanned surrogate. After analyzing the scans of the same objects with these different methods, the conclusion is that photogrammetry has the power to provide a highly detailed model very fast but with several distortions. The depth camera provided smoother surfaces and higher error. Ultimately, each method presented multiple possibilities for materialize itself, depending on target resolution and how detailed the object must be to correctly understand it.
