Security, Encryption, and You

November's terrorism attack in Paris elicited efforts by US officials to restrict or provide alternate means for decrypting messages. People in the Congress and the Intelligence Agencies repeated older requests for backdoors that would allow them to decrypt messages and content on devices.

VR News Videos from NY Times

The NY Times announced that they will be publisihing VR (360) news videos for Cardboard. They have just completed their second VR video. The Times will soon send all of their subscribers "Google Cardboard" to view these. There is another video scheduled for December and at least one more in 2016. This video, "The Displaced", tells the story of three children displaced by war and fighting and violence.

X3D Event Model

Events in X3D are the means for generating and handling behaviors. All changes in the state (including geometry, appearance, animation; but not animated images) are because at least one event was generated and processed. Events can be generated by timers, user interactions, response to other events, or from external sources. Events are routed fro a particular field of a node to another field of a different node. This cycle repeats throughout the time the scene is running. 

X3D Futures: Structure of the Next Version

I have been doing a lot of thinking and talking with people working in computer-based 3D graphics to determine what the next generation of X3D should look like. There are important considerations and practices that need to be addressed. This post is an attempt to summarize the current state of X3D and the industry (primarily non-X3D) process of creating 3D scene. The next part will outline some of the options for the next generation.

Declaractive 3D Goals

In starting any new effort, it is important to identify the goals of the project. Goals are important because they provide a focus for the most desired outcome. They are not necessarily the destination of a project, as there are a number of factors that may limit (or expand) the initial goals.

I am working on developing the standard for the next generation of declarative 3D graphics. The current version is called X3D. At this time that name I am using for this is X3D V4. Final naming is not up to me.

3D Panoramas

Recent advancements in camera and mounting technology create full panoramas of your environment. These are great for outdoor shots that you just can't seem to capture with a regular camera.

Thoughts on Hollywood VR

This is a short rant on Virtual Reality as seen by some people in Hollywood. First, by "Hollywood", I mean the general community of movie directors and producers that have their story to tell and you WILL watch it. They seem to believe that "Reality" means sitting a watching. You don't get to explore, you don't get to push buttons or pull levers, throw the ball, swing a stick, or jump off the roof. Everything that you can do in real life and probably did as a kid. I'm beginning to think they have gotten old already.
