完成才會征服

Basic Geometric Objects, the OpenGL and their use through OpenGL drawing commands are explained. The graphic primitive points, lines, triangles, polygons and quadrilaterals (quads) used in the OpenGL are considered in more detail. The OpenGL has graphic primitives to draw sequences of basic objects, allowing surfaces of ob

Modelling Three-Dimensional Objects,importance in computer graphics, special attention is given to this. Often the (curved) surfaces of objects are approximated by planar polygons. Triangles are particularly well suited for this. In modern graphics processors, the tessellation unit can decompose a curved surface into planar polygons i

Geometry Processing,jects on the screen. After introducing the concepts in the two-dimensional plane, they are applied in three-dimensional space. The first step is the geometric modelling of each object as a model of the virtual world to be represented. This modelling is done for each object in its own coordinate syst

Rasterisation, and scenes of objects to be transformed efficiently and without loss of detail. However, for display on common output devices, it is necessary to convert this vector-based representation into a raster graphic. This conversion process is referred to as rasterisation.

Lighting Models,led computer graphics scene, the light from modelled light sources hits the surface of objects, is reflected there and creates lighting effects depending on the material properties of the object surfaces. The Phong model is presented as an important representative of local illumination models. Furth

Textures,d to the surface of an object. They can be used to define or change the appearance of the surface of the object. Both the colour design and the geometry of the object can be influenced. Textures can be two-dimensional, most commonly in flat rectangular form, or three-dimensional in curved form. Text
