Software Engineering Tech Trend (SETT): Experiments With JavaFX 3D Scenes

Wed, 02 May 2012 03:28:20 GMT

The last article I wrote for OCI's online newsletter Java News Brief (JNB) was Six JDK Classes You Think You Know, which several readers have told me was fun. That was the last article in the JNB series. The following month, the series began its publication under the new name Software Engineering Tech Trend (SETT), with an expanded scope covering a broader array of software engineering topics. Here's a sample of the articles that was published in SETT in the last year and a half:

In this months SETT article, Experiments With JavaFX 3D Scenes, I show you one aspect of JavaFX, its 3D scenes support, through a set of experiments that go from simple animated squares moving along straight lines to an animated formation of a tetrahedron in 3D. I was hoping to show you an animation of a dodecahedron being formed from a stack of pentagons,but I ran out of time for the article and have to settle for a tetrahedron there.

I did, however, finish an animated dodecahedron after I submitted the article. And here is how it goes:

Enjoy!

This is the first release of OpenDDS that conforms to the minimum compliance profile as documented in formal/07-01-01 (version 1.2). Near-complete support for the persistence profile and initial support for the content-subscription profile is also provided in this release.

Numerous API updates have been introduced for 1.2 compliance.

A number of QoS policies have been updated or implemented to meet the minimum compliance profile:

DESTINATION_ORDER

ENTITY_FACTORY

LIVELINESS

PRESENTATION

READER_DATA_LIFECYCLE

TIME_BASED_FILTER

WRITER_DATA_LIFECYCLE

Fixed bugs in QueryCondition.

OpenDDS 1.3 Released

Wed, 29 Jul 2009 12:07:04 GMT

Adam has announced a new release of OpenDDS, an open source implementation of the Object Management Group (OMG) Data Distribution Service (DDS) by OCI. It is implemented in C++ and supports C++ and Java bindings.

OpenDDS.org:
Version 1.3 Released

We are pleased to announce the release of OpenDDS version 1.3!

Improved OMG DDS 1.2 specification conformance:

Communication Status entity structures and behaviors

Implemented TRANSPORT_PRIORITY and LATENCY_BUDGET QoS

Implemented the ReadCondition interface and associated operations on the DataReader

Partially implemented the QueryCondition interface—only queries of the form "ORDER BY a[, b, c...]" have any effect

Implemented DataWriter::wait_for_acknowledgements()

Instance handles and related operations are now spec-compliant

Fixed bugs in DURABILITY, PARTITION and LIFESPAN QoS

Added a command-line utility, opendds_repo_ctl for controlling the DCPSInfoRepo server

Deleting a DataWriter now blocks, for a configurable amount of time, until pending samples have been delivered by the transport.

Added a Java Message Service 1.1 (JMS) provider built on top of OpenDDS

Added Windows Mobile 6 as a supported platform

See the Release Notes for details.
