JSR 184: Mobile 3D Graphics

The Mobile 3D Graphics API for J2ME, (JSR 184) provides 3D graphics capabilities with a low-level API and a high-level scene graph API. This chapter provides a brief overview and general guidelines for working with JSR 184.

JSR 184 is a specification that defines the Mobile 3D Graphics (M3G) API for the J2ME. This API provides 3D functionality in a compact package that’s appropriate for CLDC/MIDP devices. The API provides two methods for displaying 3D graphics content:

The immediate mode API makes it possible for applications to directly create and manipulate 3D elements.

Layered on top of this is a scene graph API, also called retained mode, that makes it possible to load and display entire 3D scenes that are designed ahead of time.
