Introduction to Modern Geometry Modern Geometry: The Directed Line Segment In Euclidean Geometry, line segments possess only magnitude, and not direction. A B      Figure 1:   In Euclidean Geometry, only the magnitude of line segments is considered. As we can see in Figure 1 , in Euclidean Geometry, the line segment: |AB| would be considered equal to the line segment: |BA| . However, this is not the case with Modern Geometry. In Modern Geometry, line segments not only possess magnitude, but direction also. A B      Figure 2:   In Modern Geometry, line segments possess direction as well as magnitude. In Modern Geometry: |AB| is termed: ‘a directed line segment’ . ...

     Figure 1:   A Venn diagram that illustrates how information, or data is grouped as regards Structured Query Language. How information is grouped together within programming languages is an important concept to grasp.  I find that the drawing of Venn diagrams assists me with this.

My first X3DOM page Hello, Cube!      Figure 1:   It is possible to script Three-dimensional objects with X3DOM.  X3DOM follows the declarative scripting paradigm of two-dimensional SVG as opposed to following the programming imperative paradigm of JavaScript and Canvas. This is my first html page that includes a three-dimensional object. X3DOM is a Javascript library that allows one to code three-dimensional objects - such as cubes, speheres, cylinders, etc. - with tags, just as SVG allows one to do with two dimensional objects - squares, circles etc. You can manipulate the below cube with your finger - should you be employing a touchscreen - or with your mouse cursor - should you be employing a desktop. Should you use two fingers on a touch-screen device, then you can scale the size of the cube in real time. Holding one's two fingers to the screen...
