3D Shape Deformation Using Stick Figures
Seylan, Çağlar; Sahillioğlu, Yusuf (2022-10-01)
Obtaining new poses of an articulated character is a critical task in computer graphics. We address this issue with a new shape deformation approach consisting of two phases enabling the user to express the new pose as a s...
Scale-Adaptive ICP
Sahillioğlu, Yusuf; Kavan, Ladislav (2021-07-01)
We present a new scale-adaptive ICP (Iterative Closest Point) method which aligns two objects that differ by rigid transformations (translations and rotations) and uniform scaling. The motivation is that input data may com...
Part-based data-driven 3D shape interpolation
Aydinlilar, Melike; Sahillioğlu, Yusuf (2021-07-01)
An active problem in digital geometry processing is shape interpolation which aims to generate a continuous sequence of in-betweens for a given source and target shape. Unlike traditional approaches that interpolate source...
Human body reconstruction from limited number of points
Tastan, Oguzhan; Sahillioğlu, Yusuf (2021-04-01)
We propose a novel approach for reconstructing plausible three-dimensional (3D) human body models from small number of 3D points which represent body parts. We leverage a database of 3D models of humans varying from each o...
Voxel transformation: scalable scene geometry discretization for global illumination
Yalciner, Bora; Sahillioğlu, Yusuf (Springer Science and Business Media LLC, 2020-10-01)
In real-time computer graphics, efficient discretization of scenes is required in order to accelerate graphics related algorithms such as realistic rendering with indirect illumination and visibility checking. Sparse voxel...
Recent advances in shape correspondence
Sahillioğlu, Yusuf (Springer Science and Business Media LLC, 2020-08-01)
Important new developments have appeared since the most recent direct survey on shape correspondence published almost a decade ago. Our survey covers the period from 2011, their stopping point, to 2019, inclusive. The goal...
Generation of 3D human models and animations using simple sketches
Akman, Alican; Sahillioğlu, Yusuf; Sezgin, T. Metin (2020-01-01)
Generating 3D models from 2D images or sketches is a widely studied important problem in computer graphics. We describe the first method to generate a 3D human model from a single sketched stick figure. In contrast to the ...
A fabrication-oriented remeshing method for auxetic pattern extraction
Mert, Levend Mehmet; Yaman, Ulaş; Sahillioğlu, Yusuf (The Scientific and Technological Research Council of Turkey, 2020-01-01)
We propose a method for extracting auxetic patterns from meshes for fabrication by modifying the existing mesh primitives directly and fully automatically. This direct approach is novel in the sense that most of the fabric...
3D indirect shape retrieval based on hand interaction
Irmak, Erdem Can; Sahillioğlu, Yusuf (Springer Science and Business Media LLC, 2020-01-01)
In this work, we present a novel 3D indirect shape analysis method which successfully retrieves 3D shapes based on hand-object interaction. To this end, the human hand information is first transferred to the virtual enviro...
3D skeleton transfer for meshes and clouds
Seylan, Çağlar; Sahillioğlu, Yusuf (Elsevier BV, 2019-09-01)
We present a curve-skeleton extraction method in the form of curve-skeleton transfer from the source shape to the target. The shapes we deal with need to be in correspondence. They are discretized as meshes embedded in 3D ...
