ABSTRACT
IMPLEMENTATION OF SPHERICAL ENVIRONMENT MAPPING ALGORITHM USING OPENGL
By Felix Oey
SWISS GERMAN UNIVERSITY Bumi Serpong Damai
Richard Kumaradjaja, PhD, Major Lecturer
In rendering computer graphic projects, 3D rendering tools such as 3D MAX or MAYA already became a most wanted option. Moreover, through this paper, the author wants to show that rendering a 3D scene is not always need tools. Besides, implementing spherical environment mapping algorithm in rendering a scene is possibly done without immense hindrances.
Functions for creating objects, positioning them in the scene, defining the lightning and material properties, applying the texture mapping and environment mapping are all available in OpenGL library. Subsequently, the task is to utilize those functions to be used in creating the scene.
The point of doing this project is rendering a 3D image that possibly done without using any image rendering tool. In fact, coding an OpenGL application is not that complicated.
In short, this could be an alternative way to learn or to render 3D scenery instead of
