We present a spatial and angular Gaussian based representation and a triple splatting process, for real-time, high-quality novel lighting-and-view synthesis from multi-view point-lit input images. To describe complex appearance, we employ a Lambertian ...

Deep learning-based approaches have shown great achievement in 3D point analysis. Due to the irregular and unordered data structure, point cloud analysis is still very challenging. Most existing work uses the convolution, graph, or attention ...

The need for 3D and 4D (i.e., 3D + time) shape analysis arises in many branches of science ranging from anatomy, bioinformatics, medicine, and biology to computer graphics, multimedia, and virtual and augmented reality. In fact, shape is an essential ...

Although it is commonly held that geometrical diagrams can represent constructions, the nature of the construction representations has rarely been closely investigated. There is no clarity on the subject of construction nature nor the nature of ...

We present work-in-progress on RTG, a domain specific language embedded in Haskell designed to explore the affordances of geometry as a means to generate and manipulate rhythmic patterns in live coded music. Examples of how simple geometry is capable of ...

Properly defining the center of a set has been a longstanding question in applied mathematics, with implications in numerical geometry, physics, and optimization algorithms. Minkowski centers are one such definition, whose theoretical benefits are ...

Centers of convex sets are geometric objects that have received extensive attention in the mathematical and optimization literature, both from a theoretical and practical standpoint. For instance, they serve as initialization points for many algorithms ...

We formalize Pick’s theorem for finding the area of a simple polygon whose vertices are integral lattice points. We are inspired by John Harrison’s formalization of Pick’s theorem in HOL Light, but tailor our proof approach to avoid a primary ...

Data augmentation is widely recognized as an effective means of bolstering model robustness. However, when applied to monocular 3D object detection, non-geometric image augmentation neglects the critical link between the image and physical space, ...

This study aimed to test the effectiveness of using augmented reality applications in learning geometry in junior high school students. The method used in this study is the quasi-experiment method. In this study, researchers used learning with ...

Classical microfacet theory suffers from energy loss on materials with high roughness due to the single bounce assumption of most microfacet models. When roughness is high, there is a large chance of multiple scattering occurring among the microfacets ...

A learning-based YOGA (Yet Another Geometry-based Point Cloud Compressor) is proposed. It is flexible, allowing for the separable lossy compression of geometry and color attributes, and variable-rate coding using a single neural model; it is high-...

With the recent progress in geometric deep learning, generative modeling, and the availability of large-scale biological datasets, molecular graph and geometry generative modeling have emerged as a highly promising direction for scientific discovery ...

A geospatial Knowledge Graph (KG) is a heterogeneous information network, capable of representing relationships between spatial entities in a machine-interpretable format, and has tremendous applications in logistics and social networks. Existing efforts ...

We present an algorithm to compute planar linkage topology and geometry, given a user-specified end-effector trajectory. Planar linkage structures convert rotational or prismatic motions of a single actuator into an arbitrarily complex periodic motion, ...

3D shape generation is a fundamental operation in computer graphics. While significant progress has been made, especially with recent deep generative models, it remains a challenge to synthesize high-quality shapes with rich geometric details and complex ...

A polygonal mesh is the most-commonly used representation of surfaces in computer graphics. Therefore, it is not surprising that a number of mesh classification networks have recently been proposed. However, while adversarial attacks are wildly ...

Seams play a fundamental role in the way a garment looks, fits, feels and behaves. Seams can have very different shapes and mechanical properties depending on how fabric is overlapped, folded and stitched together, with garment designers often choosing ...

We provide a necessary and sufficient condition for the uniqueness of penalized least-squares estimators whose penalty term is given by a norm with a polytope unit ball, covering a wide range of methods including SLOPE, PACS, fused, clustered and ...

Artists at Insomniac Games created a wonderful and detailed open world, Marvel's Manhattan in autumn, on the PlayStation 4 console for Marvel's Spider-Man. This technical communication provides an overview of several procedural systems developed or ...

Many algorithms for virtual tree generation exist, but the visual realism of the 3D models is unknown. This problem is usually addressed by performing limited user studies or by a side-by-side visual comparison. We introduce an automated system for ...
