II - Performance in the API - Due to some introduced bugs in the Java3D API some of the most important performance features are effectively disabled. As of Java3D 1.7.0 they can be turned back on but will require some code changes through any given project due to the possibility of reliance on the features that broke the compilation system. In order to maximize compilation of the scene graph you must have these properties set: - j3d.defaultReadCapabilities = false + j3d.defaultReadCapability = false j3d.defaultNodePickable = false j3d.defaultNodeCollidable = false Also, contrary to documentation you MUST manually call compile on BranchGroups and SharedGroups before adding them to the scene graph, it does not happen automatically. + With defaultReadCapability set to false you will need to enable any read capabilities, but be aware that they should only + be set enabled where necessary as they heavily impact the compile function. + Note when using the new Jogl2es2Pipeline, there are no display lists, so all references to their usage below are not valid. + There are a number of things in the API that were included specifically to increase performance.
