2024年10月29日 · This conformational energy dataset, developed as part of the Smart Distributed Data Factory (SDDF) project, contains over 2.17 million molecular conformations based on drug-like molecules sourced from the ENAMINE database. Energies were calculated using DFT with the ωB97x density functional and the 6–31G(d) basis set.

2021年7月23日 · Neural networks that map 3D coordinates to signed distance function (SDF) or occupancy values have enabled high-fidelity implicit representations of object shape. This paper develops a new shape model that allows synthesizing novel distance views by optimizing a continuous signed directional distance function (SDDF).

在3d中光线追踪对于性能的消耗过大，所以sdf常常被用来作为物体的隐式表达，配合 ray marching 达到接近光线追踪的效果，也有比如 deepSDF 这种对于模型的隐式表达方面的应用。 在2d中，sdf常常被用来表示字体，原神的面部渲染中阴影部分贴图也是基于sdf生成的。 SDF的本质就是存储每个点到图形的最近距离，即将模型划出一个表面，在模型表面外侧的点数值大于0，在模型表面内侧的点数值小于0，如下所示： 与SDF对应的是Unsigned Distance Field，对于物 …

To address these issues, we propose a novel surface defect detection method joining spatial deformable convolution (SDC) and a dense feature pyramid, named SDDF-Net. First, we construct a SDC-based feature extraction network, which uses a dynamic convolutional kernel with spatial information to increase the feature extraction capability of ...

The seL4 Device Driver Framework (sDDF) aims to provide interfaces and protocols for writing and porting device drivers to run as seL4 user level programs. The sDDF is currently under-going active research and development and is largely experimental software.
