Web3D 2014 Workshops on X3D Evolution/Revolution

2014-08-08T17:06:55Z

Mmccann: /* Decide on readiness to proceed with next milestones */

The Web3D 2014 Conference [http://web3d2014.web3d.org/program program schedule] includes multiple [http://web3d2014.web3d.org/workshops X3D Workshops on Future Graphics Standards].

* ''Moderators:'' Don Brutzman (Naval Postgraduate School), Dick Puk (Intelligraphics) and Leonard Daly (Daly Realism).

'''Looking ahead.''' Common threads for all sessions are to plan cooperative work for the next year:
* What common work can we do together?
* What is our timetable of goals?
* Who else should we be talking to?
* What new features are needed?

Additional topics are welcome in each session, but please be brief since we are pushing hard to accomplish lots in a short period of time!

This page actively records notes that elaborate on the agenda topics. We are collaboratively adding key points. Volunteer scribes will keep minutes so that a colaborative workshop report emerges.

==== Fast Infoset (FI) ====

Fast Infoset was completed a few years before EXI. It compared favorably to 40 other forms of compression as part of the XML Binary Compression (XBC) effort leading up to EXI. Nevertheless FI is less efficient than EXI.

FI is used in the [http://www.web3d.org/documents/specifications/19776-3/V3.3/Part03/X3D_Binary.html X3D Compressed Binary Encoding (CBE)]. EXI can directly replace it in the
[http://www.web3d.org/documents/specifications/19776-3/V3.3/Part03/concepts.html#X3DCompressionDataFlow compression] and
[http://www.web3d.org/documents/specifications/19776-3/V3.3/Part03/concepts.html#X3DDecompressionDataFlow decompression] algorithms.

==== Efficient XML Interchange (EXI) ====

"Efficiency" means both size and speed. EXI has demonstrated compaction that always meets or beats the most commonly used compression techniques (zip and gzip). Additionally, because EXI decompression goes straight into memory rather than string characters, which then require significant additional parsing, decoding EXI is many times faster than other techniques. This approach also reduces memory requirements and power consumption on small devices. Alternative bit-centric compression schemes cannot take full advantage of those characteristics.

The [http://www.w3.org/ World Wide Web Consortium (W3C)] supervises these open standardization efforts with contributions by many companies, universities, agencies and individuals to continually improve these capabilities.

NPS student-driven research continues to provide significant explorations of XML-based compression and decompression techniques. Many opportunities are emerging.

How to create a HUD (Head Up Display)

2013-04-24T23:44:01Z

Mmccann:

To make a realistic 3D experience, many implementations need some sort of window to display information to the person navigating the 3D world.

The term HUD (Head Up Display) is adapted from the military, where modern fighter planes have a transparant display on which vital plane data is projected. This optic is placed directly in the line of sight of the pilot, making it possible to read the information without having to look away from the combat scene outside (hence the term "Head Up").

There is a new specification in the make to mix 2D and 3D content in X3D, but as long as it's not ready, we'll stick to the old-fashioned 3D (?) way...

These are the steps to follow to create a simple hud:

==Create a world==
It should include:
*a scene
*a viewpoint
*some objects to show movement across the scene
*a very large proximitysensor, with bounds large enough to encompass the area the user can navigate (here: "sensor")

==Add the HUD==
*add a transform (here: "hud")
*add another transform as a child (here: "offset")
Set the offset translation to a few meters in front and to the side from the viewpoint location. This needs a little "trial and error" after adding the text, as various browsers render in different ways.
*add a text node to it (here: "hudtext")
*add the necessary code to shape the text to your likings
*if needed, add another object (like a plane or a very flat box) as a panel right behind the text for better visibility

==Link the HUD to the sensor==
*ROUTE the sensor "position_changed" to the hud "translation"
*ROUTE the sensor "oreintation_changed" to the hud "rotation"

Done! As simple as that!

Of course there are many things that can be added to this simple example, like scripting to alter the text as you move or switches on the dashboard...

Examine mode behavior for exploring geospatial worlds

2008-09-09T17:35:32Z

Mmccann: Examine node behavior for exploring geospatial worlds moved to Examine mode behavior for exploring geospatial worlds

One of the issues raised at 2-day X3D Earth technical requirements workshop (http://www.web3d.org/x3d-earth/workshop2006/) was the need for some uniformity amongst browsers for effective user navigation in X3D Earth worlds. For MBARI's ROV Dive data visualization application (http://www.mbari.org/staff/mccann/vrml/ROVDataVis/papers/w3ds2004Paper-Rev4_submitted.pdf) we have found CosmoPlayer's Examine mode with Shift key set to Turbo Mode and Continuous Seek to be very effective and easy to use on a computer with a standard keyboard and mouse. The user needs to explore any part of the 3D world - key to enabling this capability are features in the browser that allow interactive changes to the point of rotation and movement about it with minimal keyboard and mouse operations. This is done with mouse action modification keys to:

* change the center of rotation location
* orbit about the selected point of rotation
* zoom toward and away from the point of rotation

Here are recommendations to browser developers for implementing the Examine mode to give these capabilities:

# Dragging the mouse left and right while holding the left mouse button down causes viewpoint rotation about a vertical axis that passes through the point of rotation. This vertical axis is always perpendicular to viewpoint vector. Left mouse motion rotates the viewpoint clockwise (as viewed from the top) about the vertical axis. Rotation is tied to the mouse motion - there is no damping or delay.
#Dragging the mouse up and down while holding the left mouse button down causes rotation about a horizontal axis that passes through the point of rotation. Up mouse motion rotates the viewpoint clockwise (as viewed from the right) about the horizontal axis. Rotation is tied to the mouse motion - there is no damping or delay.
# Holding the Ctrl key (or other key that may be user selectable) down modifies the left button down mouse drag movement such that up and down (Y-axis) movement causes the viewpoint to zoom toward and from the point of rotation. Left and right mouse motion while Ctrl is held down has no effect. Shift and Ctrl (or other keys that may be user selectable) held at the same time also enables zoom but disables TouchSensors.
# Holding the Alt key (or other key that may be user selectable) modifies the mouse movement such that mouse motion while the left mouse button is held down is translated into a pan of the viewpoint in a plane passing through the viewpoint perpendicular to the vector pointing to the point of rotation. Shift and Alt (or other keys that may be user selectable) held at the same time also enables pan but disables TouchSensors.
# The point of rotation can be set by holding the Shift key (or other key that may be user selectable) while pointing at an object and clicking the left mouse button. To provide feedback that the point has been selected the viewpoint shall zoom about 20 percent of the distance toward that point.
# If mouse pointer is positioned over a TouchSensor then the pointer icon shall change its appearance to indicate that a left mouse click will activate the TouchSensor.
# Holding the Shift key (or other key that may be user selectable) overrides any TouchSensor that the pointer may be over and forces the mouse to function as the viewpoint navigation tool: drag operations cause rotation, click operations cause center of rotation point selection.

For MBARI's ROV Dive data visualization application (http://www.mbari.org/staff/mccann/vrml/ROVDataVis/papers/w3ds2004Paper-Rev4_submitted.pdf) we have found CosmoPlayer's Examine mode with Shift key set to Turbo Mode and Continuous Seek to be very effective and easy to use on a computer with a standard keyboard and mouse. The user needs to explore any part of the 3D world - key to enabling this capability are features in the browser that allow interactive changes to the point of rotation and movement about it with minimal keyboard and mouse operations. This is done with mouse action modification keys to:

* change the center of rotation location
* orbit about the selected point of rotation
* zoom toward and away from the point of rotation

Here are recommendations to browser developers for implementing the Examine mode to give these capabilities:

# Dragging the mouse left and right while holding the left mouse button down causes viewpoint rotation about a vertical axis that passes through the point of rotation. This vertical axis is always perpendicular to viewpoint vector. Left mouse motion rotates the viewpoint clockwise (from a perspective above the axis) about the vertical axis. Rotation is tied to the mouse motion - there is no damping or delay.
#Dragging the mouse up and down while holding the left mouse button down causes rotation about a horizontal axis that passes through the point of rotation. Up mouse motion rotates the viewpoint clockwise (from a perspective on the right of the axis) about the horizontal axis. Rotation is tied to the mouse motion - there is no damping or delay.
# Holding the Ctrl key (or other key that may be user selectable) down modifies the left button down mouse drag movement such that up and down (Y-axis) movement causes the viewpoint to zoom in and out towards/from the point of rotation. Left and right mouse motion while Ctrl is held down has no effect. Shift and Ctrl (or other keys that may be user selectable) held at the same time also enables zoom but disables TouchSensors.
# Holding the Alt key (or other key that may be user selectable) modifies the mouse movement such that mouse motion while the left mouse button is held down is translated into a pan of the viewpoint in a plane perpendicular to the vector pointing to the point of rotation. Shift and Alt (or other keys that may be user selectable) held at the same time also enables pan but disables TouchSensors.
# The point of rotation can be set by holding the Shift key (or other key that may be user selectable) while pointing at an object and clicking the left mouse button. To provide feedback that the point has been selected the viewpoint shall zoom about 20 percent of the distance toward that point.
# If mouse pointer is positioned over a TouchSensor then the pointer icon shall change its appearance to indicate that a left mouse click will activate the TouchSensor.
# Holding the Shift key (or other key that may be user selectable) overrides any TouchSensor that the pointer may be over and forces the mouse to function as the viewpoint navigation tool.

Examine mode behavior for exploring geospatial worlds

Mmccann:

One of the issues raised at 2-day X3D Earth technical requirements workshop (http://www.web3d.org/x3d-earth/workshop2006/) was the need for some uniformity amongst browsers for effective user navigation in X3D Earth worlds. For the scientific data visualization of MBARI's ROV Dive data (paper: http://www.mbari.org/staff/mccann/vrml/ROVDataVis/papers/w3ds2004Paper-Rev4_submitted.pdf) we have found CosmoPlayer's Examine mode with Shift key set to Turbo Mode and Continuous Seek to be very effective and easy to use on any computer with a standard keyboard and mouse.

Here are recommendations to browser developers for implementation of Examine mode:

* If mouse pointer is positioned over a TouchSensor then the
pointer icon shall change its appearance to indicate that a left
mouse click will activate the TouchSensor.

2. Holding the Shift key (or other key that may be user selectable)
overrides any TouchSensor that the pointer
may be over and forces the mouse to function as the viewpoint
navigation tool.

3. Dragging the mouse left and right while holding the left mouse
button down causes rotation about a vertical axis that passes
through the point of rotation. Left mouse motion moves the near
field objects to the left.

4. Dragging the mouse up and down while holding the left mouse
button down causes rotation about a horizontal axis that passes
through the point of rotation. Up mouse motion moves near field
objects up.

5. Holding the Ctrl key down modifies the left button down mouse
drag movement such that up and down (Y-axis) movement causes the
viewpoint to zoom in and out towards/from the point of. Left and
right mouse motion while Ctrl is held down has no effect. Shift
and Ctrl held at the same time also enables zoom but disables
TouchSensors.

6. Holding the Alt key modifies the mouse movement such that mouse
motion while the left mouse button is held down is translated
into a pan of the viewpoint in a plane perpendicular to the
vector pointing to the point of rotation. Shift and Alt held at
the same time also enables pan but disables TouchSensors.

7. The point of rotation can be set by holding the Shift key while

Mmccann:

One of the issues raised at our 2-day workshop was the need for some uniformity amongst browsers for effective user navigation in X3D Earth worlds. I've tried to summarize the behaviour of CosmoPlayer's Examine mode with Shift key set to Turbo Mode and Continuous Seek. I'm sending this out for comment and consideration...

The Examine navigation mode for X3D Earth should have the following behaviors:

1. If mouse pointer is positioned over a TouchSensor then the
pointer icon shall change its appearance to indicate that a left
mouse click will activate the TouchSensor.

2. Holding the Shift key overrides any TouchSensor that the pointer
may be over and forces the mouse to function as the viewpoint
navigation tool.

3. Dragging the mouse left and right while holding the left mouse
button down causes rotation about a vertical axis that passes
through the point of rotation. Left mouse motion moves the near
field objects to the left.

4. Dragging the mouse up and down while holding the left mouse
button down causes rotation about a horizontal axis that passes
through the point of rotation. Up mouse motion moves near field
objects up.

5. Holding the Ctrl key down modifies the left button down mouse
drag movement such that up and down (Y-axis) movement causes the
viewpoint to zoom in and out towards/from the point of. Left and
right mouse motion while Ctrl is held down has no effect. Shift
and Ctrl held at the same time also enables zoom but disables
TouchSensors.

6. Holding the Alt key modifies the mouse movement such that mouse
motion while the left mouse button is held down is translated
into a pan of the viewpoint in a plane perpendicular to the
vector pointing to the point of rotation. Shift and Alt held at
the same time also enables pan but disables TouchSensors.

7. The point of rotation can be set by holding the Shift key while
pointing at an object and clicking the left mouse button. To
provide feedback that the point has been selected the viewpoint
shall zoom about 20 percent of the distance toward that point.
