Geometric artboards mainly take points, lines, circles as the basic elements, through the transformation of these basic elements, construction, measurement, calculation, animation, tracking track, etc., the construction of other more complex graphics. is a powerful tool in the teaching of mathematics and physics. For a beginner of geometry, it is necessary to understand the production process of geometry dr

First, the geometry of the Mac version of the interface introduction The Geometry artboard Toolbox is located on the left side of the interface, from top to bottom: Select or Drag Object tool, Draw Point tool, Draw Circle tool, draw segment tool, Draw Polygon tool, text Label tool, markup tool, information tool, custom tool. The Geometry artboard menu bar is pow

(typical with minimum round coverage)On the net to find the minimum round coverage of the random increment algorithm, the code is good, is

In the Daily mathematics, physics teaching, many teachers use the geometrical drawing board to make the courseware. But some novice users, they do not know very well, a lot of features are not how to reuse. The following is an example of how to add a Geometry artboard action button to create a two-segment hide/show button.The steps are as follows:1. Draw line segments and action buttons. Select the line segment tool to draw two segment AB and segment

What is Geometry ShaderThe GS exists between the Vertext shader and the fixed function vertex post-processing stage, which is optional and not necessary.The GS input is a single primitive, and the output may be 0 or more primitive.The role of GSThe main function of GS is to generate new primitive from existing primitive, which can generate new vertices "out of nothing".OpenGL official online mentions two kinds of usage:Layered rendering: For a primiti

Preface:Silverlight 2.0 beta1 has been released and has added many exciting new features: wpf ui framework, rich controls, rich network support, and rich base class library support. This is my study note, which is quite messy, so it is named as the Silverlight 2.0 series.Article. This topic describes geometry ). Using the geometry class and other classes derived from it (such as ellipsegeometry, pathgeo

I seem to have asked the big God several times, and I haven't even remembered the shame.NuGet adds Geojson4entityframework, referencing using Alatas.

DirectX11 Geometry Sample Demo We'll describe how to build the other two geometry shapes: cylinder and spheres. These shapes are useful for sky boxes, debugging, visual collision detection, and reduced rendering. For example, you might want to have all of your game characters rendered as a sphere to debug your tests. 1. How to create a cylindrical mesh. We divide the cylinder into three parts: the side, t

I'm going to turn around and do a good job of calculating geometry.Original address: http://blog.sina.com.cn/s/blog_49c5866c0100f3om.htmlIn fact, it is not recommended, just the topic they have done, and even some of the topic has not AC, let in the struggle. The reason why we recommend computational geometry is that I feel that the computational geometry of various ACM algorithms is a more practical algori

What the Chinese version of the artboard has been in the geometry of the Civil service network open download, many users reflect, in the geometry of the Chinese version of the custom tool does not contain some tools that can be directly called many friends asked me the geometry of the Chinese version of the tool does not have a custom tools to do? What about the

Original: Win10 UWP uses Geometry resources in XAMLOften encountered in XAML using vector graph, for SVG vector diagram, generally can be taken out to write in the Path of Data, so can be written as a resource, but the writing is a string, how to bind Geometry to string resources?If you write a picture in a resource, it looks like the following codePage.Resources> x:String x:Key="HomeIconGeometry">F1 M 2

Now many people are using geometry artboards as a prerequisite for math and work. Today, we will share with you how to use the toolbox in the geometry artboard.　　Geometry artboard The Toolbox is located on the left side of the interface, from top to bottom: Select or drag the Object tool, Draw Point tool, Draw Circle tool, draw segment tool, Draw Polygon tool, te

When using the geometry artboard, there are preset and advanced preset two options, which can simplify everyone's work efficiency, eliminate tedious repetitive settings, today's small series to take you to understand the next geometry artboard advanced preset options.Open the geometry artboard software, hold down the SHIFT key, and click Advanced Presets (F) Unde

Two times function is a mathematical model describing the law of the objective World movement, in the study of two times function, we have learned to use the stroke method to figure out two functions, in the geometry of the artboard we can also use the stroke method to accurately draw two functions, the following will detail how the geometry of the drawing method to draw two times function.The following ste

... Or how to upload an ESRI Shapefile to PostGIS. I 've often been asked how to copy data from a shapefile to a postgis database. postgis comes with a CommandLine-tool for this (shp2pgsql.exe ), but all it does is generate a huge SQL-textfile that you will need to run afterwards-not very efficient I think-especially with the ascii-Representation of the geometry. furthermore I 've had several problems with it regarding into international letters in th

Calculating Geometry Documents 2Dionysoslai ([email protected]) 2015/1/7Last April, I wrote the first computational geometry document, http://blog.csdn.net/dionysos_lai/article/details/24418697, and failed to continue writing the second document, On the one hand, some code has not been verified by actual project, dare not publish. Now, the 2014 project is over, the whole code has been a number of game valid

Document directory Begisline Sphere subdivision Object silhouette Shader Model 4 brings us the geometry shader. In fact, this thing already exists in some 3D animation production software, such as Maya 8. I took a look at which preview and csustan.edu of dx10 used to show you the usage and features of geometry shader. To be honest, there is really little information about this

The Geometry Sketchpad drawing is the Euclidean geometry "the ruler gauge mapping" a modern extension, the geometrical artboard may draw the geometry arbitrarily, the geometric artboard Toolbox is the tool which uses most when making the courseware, here is a brief introduction to each tool's use method in the Geometry

geometry of the operation of the process is very simple, no programming, simple operation, the teacher can draw a variety of graphics, but also in a timely manner according to the requirements of teaching, change the size of the graphic, or to draw a new graphic. Each teacher can quickly grasp the basic use of the geometry drawing board through the geometry artbo
