Skin deformation analysis for pre-operative planning of DIEAP flap reconstructi...
Timóteo, Rafaela; Pinto, David; Martinho, Marta; Gouveia, Pedro; Lopes, Daniel Simões; Mavioso, Carlos; Cardoso, Maria João© 2023 The Author(s). Published by Elsevier Ltd on behalf of IPEM. This is an open access article under the CC BY license (http://creativecommons.org/licenses/by/4.0/); Deep inferior epigastric artery perforator (DIEAP) flap reconstruction surgeries can potentially benefit from augmented reality (AR) in the context of surgery planning and outcomes improvement. Although three-dimensional (3D) models help visuali...
A Usability Study on Widget Design for Selecting Boolean Operations
Chambel Lopes, Diogo; Mendes, Helena; Portal, Ricardo; Klerk, Rui de; Nogueira, Isabel; Lopes, Daniel SimõesApplying the correct set of Boolean operations is a fundamental task in constructive solid geometry (CSG), which is a staple in automated manufacturing systems. Although textual buttons and icons are the most common interfaces to apply such operations, these require an unnecessary cognitive load that hampers the solid modeling process. This study presents VennPad, a novel CSG widget that gathers all Boolean ope...

Anatomy Studio: A tool for virtual dissection through augmented 3D reconstruction
Zorzal, Ezequiel R.; Sousa, Maurício; Mendes, Daniel; Anjos, Rafael Kuffner dos; Medeiros, Daniel; Paulo, Soraia Figueiredo; Rodrigues, Pedro"3D reconstruction from anatomical slices allows anatomists to create three dimensional depictions of real structures by tracing organs from sequences of cryosections. However, conventional user interfaces rely on single-user experiences and mouse-based input to create content for education or training purposes. In this work, we present Anatomy Studio, a collaborative Mixed Reality tool for virtual dissection t...
Geometric Detection Algorithms for Cavities on Protein Surfaces in Molecular Gr...
Simões, Tiago M. C.; Lopes, Daniel Simões; Dias, Sérgio Emanuel Duarte; Fernandes, Francisco; Jorge, Joaquim A; Pereira, João; Bajaj, ChandrajitDetecting and analysing protein cavities provides significant information about active sites for biological processes (e.g. protein–protein or protein–ligand binding) in molecular graphics and modelling. Using the three‐dimensional (3D) structure of a given protein (i.e. atom types and their locations in 3D) as retrieved from a PDB (Protein Data Bank) file, it is now computationally viable to determine a descri...
