Example-based texture synthesis has been an active research problem for over two decades. Still, synthesizing textures with nonlocal structures remains a challenge. In this article, we present a texture synthesis technique that builds upon...
We present a novel algorithm to control the physically-based animation of smoke. Given a set of keyframe smoke shapes, we compute a dense sequence of control force fields that can drive the smoke shape to match several keyframes at certain time...
A Schur Complement Preconditioner for Scalable Parallel Fluid Simulation
Jieyu Chu, Nafees Bin Zafar, Xubo Yang
Article No.: 163
We present an algorithmically efficient and parallelized domain decomposition based approach to solving Poisson’s equation on irregular domains. Our technique employs the Schur complement method, which permits a high degree of parallel...
Two-Scale Topology Optimization with Microstructures
Bo Zhu, Mélina Skouras, Desai Chen, Wojciech Matusik
Article No.: 164
In this article, we present a novel two-scale framework to optimize the structure and the material distribution of an object given its functional specifications. Our approach utilizes multi-material microstructures as low-level building blocks of...
Practical Acquisition and Rendering of Diffraction Effects in Surface Reflectance
Antoine Toisoul, Abhijeet Ghosh
Article No.: 166
We propose two novel contributions for measurement-based rendering of diffraction effects in surface reflectance of planar homogeneous diffractive materials. As a general solution for commonly manufactured materials, we propose a practical...
Implicitizing Rational Tensor Product Surfaces Using the Resultant of Three Moving Planes
Li-Yong Shen, Ron Goldman
Article No.: 167
Implicitizing rational surfaces is a fundamental computational task in Computer Graphics and Computer Aided Design. Ray tracing, collision detection, and solid modeling all benefit from implicitization procedures for rational surfaces. The...
