Mesh (engl.) in der Computergraphik bezeichnend für ein Polygonnetz zur Modellierung von 3D-Objekten, siehe auch Gitter (Geometrie)
Die Erzeugung eines Gitters aus Dreieckselementen wird auch als Triangulierung (oder Triangulation) bezeichnet (genau wie das entstehende Dreiecksgitter), die Erzeugung eines Gitters aus Viereckselementen heißt auch Paving.
Ein Mesh besteht aus einzelnen Punkten (Vertices), zwischen denen Verbindungen (Edges) bestehen, die wiederum Flächen (Faces) aufspannen.

Byte-Reihenfolge: Big- oder Little-Endian

Leave a reply

Bei Big-Endian (wörtlich „Groß-Ender“)
wird das Byte mit den höchstwertigen Bits (d. h. die signifikantesten Stellen) zuerst gespeichert, das heißt an der kleinsten Speicheradresse. Allgemein bedeutet der Begriff, dass Daten mit dem größtwertigen Element zuerst genannt werden, wie etwa bei der deutschen Schreibweise der Uhrzeit: Stunde:Minute:Sekunde.
Bei Little-Endian (wörtlich „Klein-Ender“)
wird dagegen das Byte mit den niederstwertigen Bits (d. h. die am wenigsten signifikanten Stellen) an der kleinsten Speicheradresse gespeichert beziehungsweise das kleinstwertige Element zuerst genannt, wie bei der herkömmlichen deutschen Datumsschreibweise: Tag.Monat.Jahr.
