SDF(Signed Distance Field)在3d和2d中都有对应的应用。 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。

2024年7月23日 · Below are detailed step-by-step instructions for applying SDF from start to finish. 1. Set up your tray/dappen dish. Use clean technique when handling anything that will go into the patient’s mouth. Wear gloves whenever handling SDF to avoid staining.

2017年7月10日 · the application of silver diamine fluoride (SDF) to enhance dental caries management outcomes in children and adolescents, including those with special health care needs. Silver diamine fluoride in this guideline’s recommendation refers to 38 percent SDF, the only formula available in the United States. These rec-

在实时渲染技术中，距离场（Signed Distance Fields，简称SDF）是近年来出现的一种新的图形技术，它在图形学中有着广泛的应用。 距离场 技术主要利用点、线、面到对象表面的距离信息，这些信息可以是正数也可以是负数...

Background: The caries arrest that can be achieved by using silver diamine fluoride (SDF) offers a minimally invasive and inexpensive alternative to traditional restorative caries treatment. The authors evaluated how the dentinal staining that is associated with SDF influences the acceptance of this treatment among parents of young children in ...

This article reviews current evidence on the effectiveness of silver diamine fluoride (SDF) as a caries arresting and preventive agent. It provides clinical recommendations around SDF's appropriate use as part of a comprehensive caries management program. Systematic reviews confirm that SDF is effec …

2017年9月15日 · Background: This manuscript presents evidence-based guidance on the use of 38 percent silver diamine fluoride (SDF) for dental caries management in children and adolescents, including those with special health care needs. A guideline workgroup formed by the American Academy of Pediatric Dentistry developed guidance and an evidence-based ...

2020年5月19日 · 符号距离函数（sign distance function），简称SDF，在光线追踪领域有很重要的应用。本文分析了shadertoy网站上inigo quilez大佬的关于2D基本几何图形的SDF函数，为今后的计算机图形学路程铺垫几何学基础。

"SDF Image" is a package designed for Unity that adds a functionality that should have been present from the start - high-quality outlines and shadows for UI...

这篇文章将讨论SDF的基本概念，我们可以在 ShaderToy 中找到更多相关的例子. SDF介绍. SDF和传统的 Raytracing 很类似，都需要射线射向场景中的每个像素。在Raytracer中，我们可以使用一些表达式来确定光线和需要渲染的物体的交点。
