Development Timeline
The timeline is expressed in terms of various milestones to be achieved, not
with specific dates. As an open source project, the developers tend to have
other lives too and progress is highly dependent on other projects and their
requirements, as well as direct paid development/debugging time on this
project.
One item explicitly not stated here is the relationship to the Java bindings
to OpenGL. Right now we're using JOGL for this task, while we await the
outcome of JSR-231. We
may elect to delay or release early one of these steps to work with the
release of the JSR and update our code accordingly.
Beta 1
- Core, pipeline and surface infrastructure settled
- Basic (no-frills) rendering and picking system implemented
Beta 2
- Standard pipeline features implemented (frustum culling,
state/transparency sorting etc)
- Picking implementation complete
- Multipipe/CPU rendering tested
Beta 3
- Spatialised Audio added (done)
- Sub-image update for textures (done)
- OpenGL 1.5/2.0 Shader Object support (done)
- Clip planes (done)
- 2 sided material color handling (done)
- Interfaces for defining custom culling on groups and renderables (50%)
Beta 4 (Late 2004)
- RenderingAttributes class for rasterisation stage control
- Multipass rendering capabilities
- Volume Rendering extensions
- More file loaders added
- Separating the app thread from the render thread(s)
1.0
1.1
- Layers and compositing
- Rasters
- Multisampling
- Point Sprites
- Decal/Ordered Group rendering support
- Specification safety - warning of user when the user attempts to use
a feature/extension that the local GL implementation does not support
1.2
- Cluster rendering support
- Active stereo rendering support
2.0
- Multi-threaded pipeline internals handling
- Internationalisation - particularly for error/exception messages
Short Term plans
The following is a detailed list of what we are intending to fix/change before
the next release. Items crossed off are already in CVS.
- Demo CAVE application to show multiple pipeline setup and how to create
views that are offset from the active viewpoint on a per-output device
basis (there's one in Xj3D, but a
local demo would be useful)
- Cone and cylinder pick type implementation internals.
- Ray and line segment pick sorting
- Utility tool for configuring multi-screen setup
- Investigate feasibility of glContext sharing
- Add additional scoping rules for lights, fog, clip
- Changing display lists is not correctly handled. Not calling glDeleteList()
