Android發展自2003年，廣用於手機、平板等mobile裝置，其市占率於2013年已達75%，可見其重要性。在使用者對於解析度、畫質等需求越高的情況下，純粹使用2D繪圖已稍嫌不足夠，如何將3D繪圖加以應用已為趨勢。
嵌入式系統在硬體上較受限制，所以我們考量如何在效能與畫質兼具的情況下達到3D視覺效果，經過介紹OpenGL ES的繪圖環境，本論文透過使用OpenGL ES Shading Language（GLSL ES），讓3D繪圖的應用在Android有更大的展現，實現Phong Shading、Bump Mapping、Relief Mapping、Cube Mapping等不同的繪圖（render）方式，分別介紹不同繪圖理論及作法。
除了上述提供各種適用於嵌入式的繪圖作法外，透過實作的FPS測量數據以提供硬體規格上效能考量的切換，並可作為程式開發人員選用何種繪圖方式開發的參考依據，另外，介紹Android NDK（Android Native Development Kit），由C++所寫的程式專案能夠過NDK移植到Android，帶來另一種在Android上開發3D繪圖的想法。
