Abstract Annotations are additional information associated with a specific context area in a document or other piece of information. There are a plethora of tools for annotating digital media such as documents, webpages, 2D images, or even messages exchanged in messaging applications. Annotations can augment a piece of text or a part of an image to add a note or a piece of information that can either act as a reminder to the user or to allow the user to communicate the annotated digital media in more detail to another person. While annotating 2D digital media, is something that an abundance of tools performs, 3D annotation is not explored to the same extent. 3D representation of scenes and objects is something that attracts considerable research interest in recent years and has multiple applications in real-life scenarios. While there are a couple of efforts for 3D annotation, the majority of them provide only locationbased point annotation or are bound to a specific area of interest, such as health or construction-related applications. Location-based annotation of Three-Dimensional (3D) digitization stems from the need to provide location-specific information upon 3D content modelling. Some case studies of such 3D content models are, for example, a murder scene, a natural environment, a craft workshop, a tool or a machine, etc. In addition, annotations may relate to the indication of structures; e.g., the pattern of the body of a dead man in a murder scene, a footprint from a boot left in the dirt, motifs on a textile or a vase, the shapes of a handle of a glass carafe, etc. Thereby, there is a need for a system that will facilitate such indications by providing functionalities that increase its automation. Moreover, annotations should be provided with location-specific context and information attached to the 3D model. To achieve the goal of allowing users to create 3D annotations and 3D extractions patterns in a 3D model, this thesis proposes the 3DMA. 3DMA is a prototyping system that allows users to effortlessly and effectively create 3D annotations with text descriptions and extract 3D patterns from 3D mesh models. 3DMA aims to allow users to load any type of 3D model and annotate either points or areas of the model by providing multiple features that help the users achieve their goal in a 3D model mesh with the similar effort that they would need for a 2D annotation.
