13 JSR-184 - Mobile 3D Graphics API

13.1 Overview

JSR-184 Mobile 3D API defines an API for rendering three-dimensional (3D) graphics at interactive frame rates, including a scene graph structure and a corresponding file format for efficient management and deployment of 3D content. Typical applications that might make use of JSR-184 Mobile 3D API include games, map visualizations, user interface, animated messages, and screen savers. JSR-184 requires a Java ME device supporting MIDP 2.0 and CLDC 1.1 as a minimum.

13.2 Mobile 3D API

The MOTORAZR maxx V6 contains full implementation of JSR-184 Mobile 3D API

(http://jcp.org/en/jsr/detail?id=184). The MOTORAZR maxx V6 has also imple-

mented the following:

∙Call to ￿￿￿￿￿￿￿￿￿￿￿￿￿￿￿￿￿￿ with key - microedition.m3g.version will return 1.0, otherwise null will be returned.

∙Floating point format for input and output is the standard IEEE float having an 8-bit exponent and a 24-bit mantissa normalized to 1.0, 2.0.

∙Implementation will ensure the Object3D instances will be kept reference to reduce overhead and possible inconsistency.

∙Thread safety.

∙Necessary pixel format conversions for rendering output onto device.
