Abstract
Der Algorithmus zur Umrechnung eines 3D-Objektes in den Projektionsring- Das Verfahren, welches geschützt wird, besteht aus einer beliebigen 3D-Engine, die ein 3D-Objekt darstellt, welches in dem entwickelten Verfahren um je 1° um die Y-Achse gedreht wird und das 360 mal. Bei jeder Drehung wird 1 Linie, die mittig, senkrecht über das gesamte Objekt verläuft, aufgenommen, also die Farbwerte werden eingescannt. Diese 360 Linien werden auf den Projektionsring projeziert, je 1 Linie um je 1° versetzt um den Mittelpunkt des Projektionsringes rotierend. So entsteht ein 360° Projektionsring, der das Ergebnis des Verfahrens ist.The algorithm for converting a 3D object into the projection ring The process that is protected consists of any 3D engine that displays a 3D object, which is rotated by 1° around the Y axis in the developed process and that 360 times. With each rotation, 1 line is recorded, running in the middle, vertically across the entire object, i.e. the color values are scanned. These 360 lines are projected onto the projection ring, 1 line each rotated by 1° around the center of the projection ring. This creates a 360° projection ring, which is the result of the process.

Ich habe eine kleine 3D-engine geschrieben, die nur die trivialen Objekte von opencv benutzt, wie Linien und Kreise zeichnen und direct I/O video access benutzt. In dieser 3D-engine habe ich das Verfahren implementiert und kann momentan den Prototyp, einen Würfel(cube.obj), als wavefront .obj Datei laden, sowie alle darstellbaren 3D-Objekte im .obj file format, und diese in der Variante, die ich aufgezeigt habe, darstellen.I wrote a small 3D engine using only opencv's trivial objects like drawing lines and circles and using direct I/O video access. I have implemented the procedure in this 3D engine and can currently load the prototype, a cube (cube.obj), as a wavefront .obj file, as well as all displayable 3D objects in .obj file format, and these in the variant that I have shown represent.
