Welcomes

For those who don't know or have forgotten, Blaxxun Contact (and Spazz3d) won't open some locally stored files, one many Windows XP machines.

It is a problem with spaces in directory names, eg c:\vrml\myworld.wrl opens but c:\Program Files\Spazz3d doesn't (space in "Program Files").

Then there are the function keys in Blaxxun/BS Contact.
f1 - Help
f2 - Toggle Navigation type
f3 - Hold down and click somewhere to jump to that point
f6 - Control Pad in BS Contact, list of viewpoints basically
f7 - Displays Frame Per Second, polygon count and related information. Don't leave home without it.
f8 - display current position/orientation, simply add 1.75 to the y value in position and you can use it to make Viewpoint nodes.
f9 - Preferences
f11 - Save scene to cache folder, as it as at that moment.
f12 - BS Contact create movie menu.

Another one for everyone, this is a useful change to windows itself as well.

Your typing some code or writing an email while a world is downloading, and suddenly it steals focus. Here is how to disable this stupid feature of windows.

Start > Run > regedit.exe
navigate to:
HKEY_CURRENT_USER\Control Panel\Desktop

and change the key 'ForegroundLockTimeout' using the modify option.

For windows Xp change it to : 0030d40
For Vista you need to switch modify from the BASE to DECIMAL.
Then replacing the 20000 that appears with a 0.

This also fixes the same steal focus problem in ExitReality chat, which is helpful due to the slower loading times of the chat itself. I'm sure others can name a list of 3d apps that also steal focus when they finish loading.

ParallelGraphics starts beta-testing of Cortona3D Viewer 6.0 Beta (previously known as Cortona VRML Client) and invites participants to take part in the beta testing program. Cortona3D Viewer is a fast and highly interactive VRML viewer that is ideal for viewing 3D models on the Web. It works as a VRML plug-in for popular Internet browsers such as Internet Explorer, Netscape Navigator, Mozilla, Mozilla Firefox, Opera, and Google Chrome.

Cortona3D Viewer v. 6.0 Beta: What’s new

Unicode support

Cortona3D Viewer 6.0 provides full support for UTF-8 in VRML.

Localization of the user interface

Now the menus of Cortona3D Viewer can be easily translated into other languages by licensed users.

Latest Web browsers support

Cortona3D Viewer now supports Mozilla Firefox v. 3.0 and Google Chrome.

Phong lighting support

The support for Phong lighting model is provided for graphical cards supporting the shader model v. 3.0 and higher. Limited support for the shader model v. 2.x is also provided.

Improved performance: new DirectX renderer

- Support for real-time anti-aliasing (multisampling).
- Support idle-time anti-aliasing by means of Direct3D.
- Support for composite textures.
- Improved processing of textures and 3D primitives.

Improved installation procedure

The use of Microsoft Installer (MSI) allows for easier installation of Cortona3D Viewer within an enterprise and as a part of third party applications.

New VRML extensions

- The Transform2DEx node allows for positioning layers on the screen and specifying their size in pixels.
- The CompositeTexture3D and CompositeTexture2D nodes allow for adding composite textures to the 3D scene.
- The GradientBackground node allows for creating horizontal or vertical gradient background that is static relatively to the camera movements.

Changes in VRML Automation interface

- Pick method has been changed:
Layers without background: areas with no geometry are considered transparent for the picker.
One-sided surfaces: invisible side is ignored by picker.
Double-sided surfaces: the normal calculation is based on a visible side of the surface.
- New method of geometry bounding box calculation:
§ Now the bounding box can be calculated in global coordinates.


The FreeWRL team have put FreeWRL 1.21.2 on-line, with source, debian (.deb) and Apple OSX dmg downloads.

http://freewrl.sourceforge.net

Summary of changes:
- Verified MIME types for OSX and Linux plugins.

- Classic VRML/X3D parser:
- fixed memory error when IS fields were large.
- dramatic speed improvement in PROTO expansions; visible when large protos are
instantiated.

- XML parser:
- speed increase in parsing attribute values (one test shows 100x speed increase)
- PROTO expansion and Script invocation being reworked - may still have parse errors.
(in progress)

- Source Code:
- OpenGL Shaders code should compile on OpenGL 1.5 and above now (was 2.0 and above)
- CFuncs/sounds.h - include unistd.h on Linux machines.

- Misc rendering changes:

- Javascript, direct writing to scenegraph, boolean values were not correctly translated from
javascript to freewrl internal values.

- FaceSets with Color node, not taking material properties correctly (especially transparency)

- FaceSets, with RGB Color node, keep track of associated material transparency, and work through
color node changes.

- removal of temporary files - code has been reworked, as some temporary files (specific:
files retrieved by wget or curl) were not removed.

- initial work on CubeMapTextures.

- GeoPositionInterpolator - output value not translated to local spatial units. (fixed)
