It also provides mechanisms to create preset views, shading and lighting options for 3-d figures. The libHaru free PDF library. Like the movie15 LaTeX package, libHaru provides hooks to create preset views, shading and lighting options for 3-d figures. S2PLOT's rich API of more than functions includes support for low-level geometric primitives points, lines, 3- and 4-vertex facets , intermediate-level structures disks, cylinders, cones, ellipsoids, vector and bitmap text, textured facets including billboards , and high-level science-oriented entities such as axis labels, surface and skyscraper plots, isosurfaces and volumetric renderings.
Camera interaction and control, and rendering settings are standard to all S2PLOT programs, but can be modified by the programmer. A simple but flexible callback system supports the display of time-dependent or animated geometry and the receipt of user input including 3-d object selection and manipulation.
From version 3. The PRC export module honours model tree names created this way and encloses subsequent geometry exported to the PRC file in a correspondingly-named group. This feature is critical: without it our implementation of volume rendering, billboards and frames in 3-d PDF would not be possible. Texture compression. Textures that are entirely opaque i. Textures that have transparent pixels e.
Surface mesh compression. For export to PRC format, collections of like-coloured 3- and 4-vertex facets, each with their own vertices, vertex normals and vertex colours, are combined into single-colour meshes that comprise a list of vertices and vertex normals, that are indexed to create facets. This delivers considerable savings in storage space vertices shared by typically three or four facets in a surface mesh are stored only once , and colours are stored once per mesh rather than per vertex or facet.
Additionally, collections of facets stored as vertex-indexed meshes are loaded and rendered much faster by Adobe Reader and Adobe Acrobat, than equivalent sets of individual, unindexed facets. Based on these tags, users can retrieve the files from their hard drive. If the title or abstract sound interesting, store it. You will have to reference the origin of information taken from other sources, ideally with a page number. Now, whenever you read an interesting PDF, you create a bookmark for every statement that might be interesting for your thesis.
We would also suggest highlighting the interesting text directly in the document. Have a look at the picture. It is about how to get your papers indexed and well ranked by academic search engines such as Google Scholar. Therefore you create a bookmark for each of this information see the picture. In the very beginning of your literature research, creating just one bookmark that briefly describes the paper e. A mind map is a diagram with a central topic and subtopics branching from it like a tree see the picture for an example.
Usually, a node in a mind map contains only one or two important keywords. Please download and install it. Create a new child node by pressing the Insert key on your keyboard or selecting Insert New Child Node from the menu.
Call this node Incoming Literature. Other files are ignored. And the best — also the PDF bookmarks are imported. The following picture illustrates this. Giving Structure to Your Mind Map and Literature After you have read the first PDFs and created bookmarks, you should start giving some structure to the information: Create nodes for all the important categories you plan to do research in you can change them at any time later on.
If you feel that one bookmark fits several categories, just create a copy of it. The following picture shows an example. Giving Structure to your Mind Map and Literature and hence to the thesis Now you have a good overview of what you have read. On first glance, this might seem similar to a folder structure on your hard drive and indeed it is. For instance, about differences between academic and classic search engine optimization. This behavior is due to the handling of bookmarks by the viewers and cannot be influenced by Docear.
The new bookmarks can be easily imported by performing a right click on the respective node and selecting Import Bookmarks. To get a better overview, you can fold and unfold nodes by selecting a node and pressing Space. Making Notes Another feature that makes mind maps superior to simple file systems is the possibility to add notes.
You can add any kind of text as a note to any node in the mind map. Making additional notes in the mind map Part II: Structuring and Drafting the Thesis This is the second part of our tutorial on how to write a thesis. In this part, we cover how to structure and draft your thesis. There is lots of good literature on how to structure a thesis conceptually, so we will not cover this aspect in here. However, we will show you a practical way to devise, maintain and store the structure of your thesis in a mind map.
A typical structure of a PhD thesis in a mind map You start with devising a basic structure, which you can create in your literature mind map or in a new mind map, see the picture above for an example. You can then start drafting your thesis directly in the mind map. Create one node for each heading and one sub-node for each sentence see picture below. You might wonder why not do this directly in a word processor.
Moreover, you have all the important information in your mind map already. We guarantee that you will have to restructure your thesis several times before you are really happy with the structure. The following picture shows how a final mind map for a PhD thesis could look like nodes with a circle are folded and contain additional sub-nodes. You will notice that the related work section is very similar, yet not identical to your literature mind map.
Most likely you will not use all the literature you have read. Default display settings[ edit ] PDF documents can contain display settings, including the page display layout and zoom level. Adobe Reader uses these settings to override the user's default settings when opening the document. Intellectual property[ edit ] Anyone may create applications that can read and write PDF files without having to pay royalties to Adobe Systems ; Adobe holds patents to PDF, but licenses them for royalty-free use in developing software complying with its PDF specification.
Some software can automatically produce tagged PDFs, but this feature is not always enabled by default. Adding tags to older PDFs and those that are generated from scanned documents can present some challenges. One of the significant challenges with PDF accessibility is that PDF documents have three distinct views, which, depending on the document's creation, can be inconsistent with each other.
The three views are i the physical view, ii the tags view, and iii the content view. The physical view is displayed and printed what most people consider a PDF document. The tags view is what screen readers and other assistive technologies use to deliver a high-quality navigation and reading experience to users with disabilities.
The content view is based on the physical order of objects within the PDF's content stream and may be displayed by software that does not fully support the tags view, such as the Reflow feature in Adobe's Reader. It was activated with Adobe Acrobat, but not with Acrobat Reader. Other PDF readers are also susceptible. One aggravating factor is that a PDF reader can be configured to start automatically if a web page has an embedded PDF file, providing a vector for attack.
On March 30, security researcher Didier Stevens reported an Adobe Reader and Foxit Reader exploit that runs a malicious executable if the user allows it to launch when asked.
Knowledge Engineering: Principles and Methods. It also provides mechanisms to create preset views, shading and lighting options for 3-d figures.
You might wonder why not do this directly in a word processor. XFDF 3. The following picture shows how a final mind map for a PhD thesis could look like nodes with a circle are folded and contain additional sub-nodes.
To get a better overview, you can fold and unfold nodes by selecting a node and pressing Space. Sage, This procedure yields relatively compact PRC-format files, with the speed advantage of vertex-indexed meshes, with generally acceptable colour quantization.
Security and signatures[ edit ] A PDF file may be encrypted for security, or digitally signed for authentication. That is, facets are combined together into a single-colour mesh when they are within a predefined distance of the current mesh colour, measured in RGB space. A third-party plug-in from Tetra 4D is required to create 3-d PDF figures using the approach previously described  — . Great software! If a malicious web page contains an infected PDF file that takes advantage of a vulnerability in the PDF reader, the system may be compromised even if the browser is secure.
With computers, and especially mind mapping software, new possibilities evolved. You need to create a BibTex entry for each paper you want to cite.
In Acrobat 3D, Adobe provided a relatively simple environment for importing 3-d geometry from a great number of standard 3-d formats, for configuring lighting and shading properties, and for predefining specific views. Adding tags to older PDFs and those that are generated from scanned documents can present some challenges. In the very beginning of your literature research, creating just one bookmark that briefly describes the paper e. The content view is based on the physical order of objects within the PDF's content stream and may be displayed by software that does not fully support the tags view, such as the Reflow feature in Adobe's Reader.
Thanks for making SciPlore! This feature is critical: without it our implementation of volume rendering, billboards and frames in 3-d PDF would not be possible. However, due to the static, 2-d nature of the two major contemporary publishing media paper and screen , the communication and publication of research outcomes still depends routinely on the standard 2-d plots, and less frequently, 2-d projections of 3-d renderings.
