[ L. postscriptus, ( assumed) p. p. of postscribere to write after; post after scribere to write: cf. F. postscriptum. See { Post-}, and { Scribe}.] A paragraph added to a letter after it is concluded and signed by the writer; an addition made to a book or composition after the main body of the work has been finished, containing something omitted, or something new occurring to the writer. [ Abbrev. P. S.] [ 1913 Webster] 53 Moby Thesaurus words for " postscript": PS, Parthian shot, addendum, affix, afterthought, allonge, appendix, back matter, chorus, coda, codicil, colophon, commentary, conclusion, consequence, continuance, continuation, double take, dying words, enclitic, envoi, epilogue, follow- through, follow- up, infix, interlineation, interpolation, last words, marginalia, note, parting shot, peroration, postface, postfix, postlude, prefix, proclitic, refrain, rider, scholia, second thought, sequel, sequela, sequelae, sequelant, sequent, sequitur, subscript, suffix, supplement, swan song, tag, tail A {page description language} based
on work originally done by John Gaffney at Evans and
Sutherland in 1976, evolving through "JaM" ("John and Martin",
Martin Newell) at {XEROX PARC}, and finally implemented in its
current form by John Warnock et al. after he and Chuck Geschke
founded {Adobe Systems, Inc.} in 1982.
PostScript is an {interpreted}, {stack-based language} (like
{FORTH}). It was used as a page description language by the
{Apple LaserWriter}, and now many {laser printers} and
on-screen graphics systems. Its primary application is to
describe the appearance of text, graphical shapes, and sampled
{images} on printed or displayed pages.
A program in PostScript can communicate a document description
from a composition system to a printing system in a
device-independent way.
PostScript is an unusually powerful printer language because
it is a full programming language, rather than a series of
low-level escape sequences. (In this it parallels {Emacs},
which exploited a similar insight about editing tasks). It is
also noteworthy for implementing on-the fly {rasterisation},
from {Bezier curve} descriptions, of high-quality {fonts} at
low (e.g. 300 dpi) resolution (it was formerly believed that
hand-tuned {bitmap fonts} were required for this task).
PostScript's combination of technical merits and widespread
availability made it the language of choice for graphical
output until {PDF} appeared.
The {Postscript point}, 1/72 inch, is slightly different from
other {point} units.

PostScript: n. A page description language, based on work originally done by John Gaffney at Evans and Sutherland in 1976, evolving through ‘ JaM’ (‘ John and Martin’, Martin Newell) at XEROX PARC, and finally implemented in its current form by John Warnock et al. after he and Chuck Geschke founded Adobe Systems Incorporated in 1982. PostScript gets its leverage by using a full programming language, rather than a series of low- level escape sequences, to describe an image to be printed on a laser printer or other output device ( in this it parallels EMACS, which exploited a similar insight about editing tasks). It is also noteworthy for implementing on- the fly rasterization, from Bezier curve descriptions, of high- quality fonts at low ( e. g. 300 dpi) resolution ( it was formerly believed that hand- tuned bitmap fonts were required for this task). Hackers consider PostScript to be among the most elegant hacks of all time, and the combination of technical merits and widespread availability has made PostScript the language of choice for graphical output.

- 目前研0只具备深度学习相关知识，想要入门NeRF和3DGS需要具备哪些前置知识？ - 知乎
NeRF还粘着点Neural，3DGS就完全没有神经网络的成分了。 除了利用现有深度学习做梯度下降优化，3DGS和深度学习关系不大。 NeRF 3DGS本质上还是在解决渲染的问题。 这是计算机图形学的核心内容。 不懂图形学应该还是能啃得懂NeRF。 大不了把那个渲染公式背下来嘛。
- NeRF（神经辐射场）有相关的物理（光学）原理支撑吗？
NeRF 训练和渲染的核心步骤是体渲染技术 (volume rendering)。 体渲染可以把神经场“拍平”成一张 2D 图像，从而可以和基准图像进行比较。 这个过程是可微的，所以可以用来训练网络！ 有了神经场和体渲染的预备知识，我们来介绍 NeRF 的训练。
- 基于深度学习的NeRF三维重建方法相比传统三维建模方法有什么优势？ - 知乎
Q5： NeRF相比其他表示方法有什么优势？ A1： 刘烨斌（清华大学）： 我们理解的NeRF是一个对三维场景离散的概率表达，而SDF或者mesh相比来说是一个确定性的描述，NeRF其实完全是依靠离散化策略猜测物体在空间中的表达。
- Nerf还能作为2023年的计算机视觉研究方向吗？ - 知乎
例如今年NVIDIA的GTC 2023就讨论了Nerf与当下火爆的AIGC的结合。 个人认为这个方向还是很有前途的。 除非CV出了类似chatgpt这样的东西（麻烦不要拿segment-anything出来对标了，啥时候商业化落地能这么厉害再说），否则未来的趋势中肯定有Nerf的一席之地。
- 你推荐入坑nerf吗? - 知乎
任何NeRF系统中的一个关键组件是MLP，它在移动NeRF系统上特别紧凑，在移动NeRF中的大小仅为约10 7KB。 鉴于MLP在NeRF中的重要性，从系统的角度探索潜在的增强功能至关重要。 为了加速计算并减少内存占用，常见的神经网络压缩方法包括修剪、量化、知识提取等 [6]。
- 为什么NeRF每渲染一个模型都需要重新训练一次神经网络，而其他生成模型却可以泛化呢？ - 知乎
NeRF拉胯的泛化能力正是神经渲染的一大痛点，直到2023年或许才会在更多论文里被重视起来。 该怎么让NeRF获得跨场景的泛化能力？ 其实可以从各种角度来研究这个问题。 但我觉得最值得注意的两个角度是： 引入生成模型和模型架构。
- 请问一下NeRF方向的三维重建容易发论文吗？ - 知乎
总的来说，NeRF接下来能够比较好出成果的地方更多集中在对更实际条件下各种问题的解决，以及基于NeRF延伸的各种应用、各种任务。 按照现状推测，接下来NeRF肯定会继续火爆一段时间，在各大CV、CG的顶会也会有大量的文章发表。 20221114之后的更新
- 为什么nerf没有采用transformer架构而是mlp?
因为 nerf 的关键并不是这个神经网络 mlp 也有很强的 比如 MLP-mixer 等一系列的 nerf 用的 mlp 都是低配版的 mlp, 模型并不大 Plenoxels: Radiance Fields Without Neural Networks 进一步说明, 可能连 mlp 都不需要 nerf 的本质是要记住 位置-->像素 的映射, 用 neural network 其实是让它 overfit 来完成这个记忆 都 overfit 了
