Special Issue Information

Dear Colleagues,

Computer graphics and 3D technology have made a significant impact on our daily life, ranging from fields such as the entertainment industry (film, gaming, AR/VR) and healthcare medical visualisation to industrial digital twins. With the development of AI and machine learning, the production process will be shortened, and more realistic 3D computer graphics will be available for applications. Therefore, this Special Issue will present new ideas and experimental results in the fields of 3D computer graphics, real-time graphics, computer vision and machine learning, ranging from the design, algorithm development and theoretical stages to the graphics’ practical use.

Areas relevant to computer graphics, geometric modelling, computational geometry, computational photography, 3D reconstruction, shape and surface modelling include, but are not limited, to real-time graphics rendering techniques, volume rendering, computer animation and simulation, physically based modelling, computer vision for computer graphics, machine learning for graphics, data compression for graphics, metaverse (VR/MR/XR), computational fabrication and scientific visualisation.

Learning object shapes from a single image is challenging due to variations in scene content, geometric structures, and environmental factors, which create significant disparities between 2D image features and their corresponding 3D representations, hindering the effective training of deep learning models. Existing learning-based approaches can be divided into two-stage and single-stage methods, each with limitations. Two-stage methods often rely on generating intermediate proposals by searching for similar structures across the entire dataset, a process that is computationally expensive due to the large search space and high-dimensional feature-matching requirements, further limiting flexibility to predefined object categories. In contrast, single-stage methods directly reconstruct 3D shapes from images without intermediate steps, but they struggle to capture complex object geometries due to high feature loss between image features and 3D shapes and limit their ability to represent intricate details. To address these challenges, this paper introduces SS3DNet-AF, a single-stage, single-view 3D reconstruction network with an attention-based fusion (AF) mechanism to enhance focus on relevant image features, effectively capturing geometric details and generalizing across diverse object categories. The proposed method is quantitatively evaluated using the ShapeNet dataset, demonstrating its effectiveness in achieving accurate 3D reconstructions while overcoming the computational challenges associated with traditional approaches.

We introduce a novel computational paradigm for reconstructing solid computer-aided design (CAD) features from the surface of a segmented manifold triangular mesh. This paradigm addresses the challenge of capturing high-level design semantics for manifold triangular meshes and facilitates parametric and variational design capabilities. We categorize four prevalent features, namely extrusion, rotation, sweep, and loft, as generalized swept bodies driven by cross-sectional sketches and feature paths, providing a unified mathematical representation for various feature types. The numerical optimization-based approach conducts geometric processing on the segmented manifold triangular mesh patch, extracting cross-sectional sketch curves and feature paths from its surface, and then reconstructing appropriate features using the Open CASCADE kernel. We employ the personalized three-dimensional (3D) printed model as a case study. Parametric and variant designs of the 3D-printed models are achieved through feature reconstruction of the manifold triangular mesh obtained via 3D scanning. Full article
