Abstract

This article proposes a data structure of a 3D engine based on rapid indices. Taking a model for a construction unit, this data structure can construct a coordinate array with 3D vertex rapidly and arrange those vertices in a sequence of triangle strips or triangle fans, which can be rendered rapidly by OpenGL. This data structure is easy to extend. It can hold texture coordinates, normal coordinates of vertices and a model matrix. Other models can be added to it, deleted from it, or transformed by model matrix, so it is flexible. This data structure also improves the render speed of OpenGL when it holds a large amount of data.
