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

A lot of students in the study of geometry will use a number of auxiliary tools, geometric artboard is one of them . It is often used to draw various geometric shapes, even some dynamic ones, such as triangles, circles, polygons, and so on. Using the geometry artboard to draw some basic graphics is actually very simple, if not, you can also learn about the tutorials. Here's a tutorial to share how to draw a

In the geometry artboard, the function editor can not only use the basic functions of the system to edit functions, but also perform complex function calculations and draw the image of complex functions. The following is a description of the image of a composite function of a geometric artboard .For example, a known function f (x) =x3-2x-1, drawing an image of two functions f (x) and F (x2).　　The steps are as follows:1. Select "Data"--"new function",

Thank you for compiling Nehe's OpenGL pipeline tutorial, as well as yarn translation finishing.Nehe OpenGL Lesson 18th: Two geometryTwo times geometry:With two times of geometry, you can easily create balls, discs, cylinders and cones.Two-ti

Many users of the geometry artboard will not only use panning, rotation, zooming, reflection, and iteration, but can also create a new change rule to satisfy the transformation of their own implementation if there is a need for a custom transform. This is actually a custom transformation. There are many examples of custom transformations, and the following is an example of how to create a glide reflection transformation using the

In the geometry of the drawing and drawing on the blackboard and the paper is not the same, there is no direct use of the eraser or the blackboard wipe to erase the picture, but in the geometric artboard if you draw the wrong picture or do not need a graphic, you can not let it show, so it does not hinder the continuation of the drawing. The following is an example of how to remove a drawn segment in a geometric artboard for detailed introduction.Meth

The geometric sketchpad can be used to reveal the dynamic geometric problems, but the presentation function is relatively inferior to that of PowerPoint. If the two can be combined, their performance will be more satisfying. After a few attempts, I found a way to invoke the geometry artboard file in PowerPoint as follows: 1. First in the geometry of the artboard to make a file such as: Example 1.GSP. 2. S

to rotate a point around another point in a geometry artboard tutorial The specific steps are as follows: Step one assumes fixed point is a, need to rotate point of B, select "Point Tool" in the artboard blank area draw point A, B; the angle of the mark is the ∠MOP that exists in the drawing area, select the line segment tool to draw any ∠mop in the blank of the artboard. Geometry artboard S

ArticleDirectory 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

geometric artboards are a common tool used in the teaching of mathematics and physics. Help a lot of users to complete their own courseware, to provide a lot of convenience to everyone. Let us introduce to you what are the features of Geometry artboards?The characteristics of geometry board are mainly embodied in the following aspects:First, convenient communication toolsSince each artboard can be modified

The method of the label of the geometry artboard input letter The specific steps are as follows: Step one to draw the graphic. Open the geometry artboard software and draw the geometry you need on the artboard, such as using the Polygon tool to draw the Pentagon as shown in the following figure. Geometry artb

graphics and text tutorial with degree annotation in geometry artboard The specific steps are as follows: Step one opens the geometry artboard, selects the left-hand toolbox "line ruler Tool", draws any ∠abc in the blank area of the artboard, as shown in the following figure. Geometry artboard The degree of the step two metric angles. Using the mo

What is Geometry? Geometry objects, such as EllipseGeometry, PathGeometry, and GeometryGroup, can be used to depict geometry of two-dimensional (2-d) shapes. These geometries are depicted for many purposes, such as defining a shape to be drawn to the screen or defining a clipping region. Geometry objects can be simple

Problem DescriptionIn Geometry, the problem of track is very interesting. Because in some cases, and the track of point is beautiful curve. For example, with polar coordinate system,ρ=cos3θis like rose,ρ=1−sinθis a cardioid, and so on. Today, there is a simple problem on it which you need to solve.Give a triangleδabc Andab = AC. M is the midpoint of BC. Point P is INΔABC and makes MIN{∠MPB+∠APC,∠MPC+∠APB} maximum. The track of P isγ. Wouldyou Mind Cal

After you create a new artboard file, save it so that you can use the shortcut key Ctrl+s to save it at any time during the production process. This tutorial describes three ways to save Artboards files .The three ways to save artboard files in a geometry artboard are as follows:Method One: Use the Save buttonGeometry artboards Save Artboard filesAfter you create a new artboard file, click the Save button in the File menu, or use the shortcut key "Ctr
