LucidShape Usermeeting in Nuremberg
|
On April 9, 2008, the first LucidShape user meeting proceeded
in Nuremberg, Germany at the Georg-Simon-Ohm University. Lead managed
by Prof. von Hoffman of efi (Fakultät Elektrotechnik, Feinwerktechnik,
Informationstechnik), the event was a big success for all participants.
All
german suppliers and users of LucidShape's lighting technologies
were invited to discuss current LucidShape topics. New features
of the upcoming version 1.7 were introduced, new ideas for further
LucidShape development were discussed, and new customers were welcomed.
Because of the huge number of interested people and the many positive
reactions we received, the user meeting is very likely to proceed
on a regular basis in the future years. A sincere "Thank You!"
is given to all participants and all those who made the event possible.

Release of LucidShape 1.6.2 and LucidDrive 1.1.2
User Interface
- "save selected as" no longer changes the current document's name to
the new name
- "save as" for an lue file with a script setup no longer changes the
current document's name to the new name
- "select medium library file" under options behaves like "select
material before"
CAD
- new dialogs for "Catia Transfer" and "Rhino Transfer"
- on IGES and STEP import: generate an ObjectVector for each layer and
BREP object
Script language
- a new function exit() terminates the execution of the script
- new function type void; No need anymore for "pseudo double" function
without a return value.
- script function getCurrentView()
Dialog
- migration of internal C++ dialogs into script functions. When
changing the focus from view to view,
the current model "follows" the dialog, and the dialog is
automatically updated to the new model.
the 2 dialogs:
Navigation UVData
UVData properties
have been changed. Other dialogs will follow shortly.
- the BSDF wizard dialog is also added to the material dialogs
- new dialogs for selecting Lumen or Watt in emitter materials
- "Add file" dialog code now in script code and improved
- menu item texts now identical to corresponding dialog box caption
texts
- new feature "select by color" via selection of an object and use of
the object's color
- point light source for LED now with axis system
- "assign material" now only for "unused surfaces" instead of "all
surfaces"
- new suffix type .luc for configuration files
UV Data / LucidLite
- new bird's eye view which allows the setting of the aiming position
of up to 2 headlamps
- similar to bird's eye view, a driver view diagram with viewing
parameter and aiming position of up to 2 headlamps
- several applications are improvments and migration into .do scripts
+street illumination
+simple room illumination
+static automotive road illumination
+LID editor
+interpolate LID
- colors in text output for LID test tables. Critical entries now
displayed in red.
Simulation
- new 3D Volume sensor, enables measurement of absorbed light flux in
user defined box shaped volumes
- improvements in "inside" test for trimmed surfaces
- some LED emitters with spectral curves (provided by LED manufacturer
OSRAM)
- Spooling (for details, please ask for further documentation)
- Simulation Jobs can be put into a queue that is being
processed by a spooling process to be started from LucidShape
- Jobs can be processed locally, using multiprocessing on one
computer or using several computers like LucidRemote
- LucidRemote
- is still included but the spooling process will completely
replace it in the near future
Geometrical Modelling
- new function: surface from up to 4 border curves; no longer as
application
- new function: reduce degree of curves and surfaces
Poly Curve Systems
- variable weight factors along the curve direction; instead of just
one double factor now a control curve may be applied
- surface connection of the VaroSurface now also "elliptical" of degree
2 instead of degree 3
MacroFocal Systems
- new improved dialog for gap settings
- 3 new gap types "step back no gap ...": works like the "no gap ..."
cases but with step back onto the surface.
Usefull for lenses, where an explicit gap/step is not wanted and a
slight reduction in light quality can be accepted.
Works also with reflectors.
- A "To Catia" button supports the direct transfer of the
reflector/lens surface to catia.
Works the same like the "Catia Transfer" dialog.
- automatic stop of the the reflector surface calculation when the
slope becomes too steep.
- new MF application for dual source system like H13, HB7, H4 ...
- besides the major source, a secondary source can be defined and used
for simulations.

***** Special new feature in 1.6.1:
STEP AND IGES IMPORT AND EXPORT ****** In 1.6.1,
you may read/write STEP and IGES files direct instead of reading
via Rhino3D. The path via Rhino3D is well proven and therfore
still used by default. If you want to use the direct read of IGES/STEP,
just go to Options -> Global Settings -> CAD Transfer Options

The ISAL 2007 in Darmstadt was a
great success for all participants. Among the main topics of the
conference were new LED driven headlamps, Adaptive Frontlighting
Systems (AFS) and innovative computational methods to handle
related problems (for example heating). We were proud to show that
our software tools are highly capable of creating, testing and
simulating these technologies.
Most interest was attended to our
latest Night Driving Simulator as a special highlight at the ISAL.
The build-up consisted of a network of three LucidDrive computers.

 |

|
In fact, our simulation software
LucidDrive seemed to hit the community's nerve and achieved much
acclaim. One interested party even stated that it was "the
best night driving simulation ever seen".
We would like to thank all
visitors and customers for their interest in our products, and we
hope to welcome you again on the next ISAL 2009.

LucidShape
and LucidDrive under VISTA
LucidShape and LucidDrive are both running
under VISTA. But we do not recommend to install it at the moment under VISTA for different
reasons:
1) We have encountered an error in the default (generic)
OpenGL driver for VISTA. We made adjustments to overcome these problems, but
we cannot rule out any other errors. We recommend to download the latest graphics
card drivers from the vendor of your graphics card. If it is essential to install
LucidShape under VISTA, one should always use the hardware graphic accelerator
(OPTIONS/HARDWARE GRAPHIC ACCELERATOR).
2) The normal VISTA user cannot write into the "Program
Files" directory. If the system administrator installs programs and these
programs have to write data to this directory, VISTA creates an additional folder
instead. This folder is called "Compatibility Files". The normal user
can also write data to this folder. The better option is of course if the system
administrator allows the user to write data to the folder "Program Files/LucidShape".
3) We do have principle problems with COM interface and DDE.
March 9, 2007
