Version
2.0 represents a dramatic leap in functionality for
Photopia. This version has been redesigned from
the ground up to incorporate a new CAD system, new
Parametric Optical Design Tools, and refined output.
Best of all, the calculation engine is faster than
ever - 150 times faster or more. Here are the Top
10 New Features:
1 |
Parametric
Optical Design Tools ::
(more info)
new optical design tools that allow for
the creation of 2D profiles, full 3D circular
parts, 3D symmetric extruded parts, and
3D asymmetric extruded parts. The tools
can produce complete reflector curves based
on input data that describes key features
of the reflector, plus a list of aiming
parameters for each zone of the distribution.
Reflector design iterations based on new
aiming schemes can be created interactively
as parameters are changed. These revolutionary
tools account for the effects of extended
light sources and non-specular materials. The
result - optical designs can be completed
in minutes instead of days. |
2 |
Internal
CAD System :: a new, internal
CAD system allows for both the creation
of new parts and for the manipulation of
any component of the optical model. Users
will be able to produce basic models directly
within Photopia. Companies with only 2D
CAD systems can import their profiles into
Photopia and turn them into 3D models.
The CAD system is controlled via the menu,
toolbars, and a command line that uses
a similar command set and nesting featues
to that found in AutoCAD™. |

Speed,
speed, speed :: (more
info) the raytrace engine now works
much more efficiently with large numbers
of surfaces. The result - complex models
can see speed improvements of 150 times
or more. Example: A model containing 100,000
surface elements can now be analyzed with
500,000 rays in just a few minutes. Check
out speed
comparison charts. |
4 |
Import
STL files :: this new feature
simplifies compatibility with even more
CAD packages. Almost all CAD packages produce
STL (stereo lithography) files, including:
Pro/Engineer™, Solid Edge™, SolidWorks™,
and SDRC™. This feature removes the
need to translate IGES files via third
party programs. |
5 |
Unlimited
number of surfaces :: With STL
files of arbitrary smoothness and fast
calculations, the types of optics that
Photopia can handle is now expanded to
almost any system imaginable - even complex
curved lenses and reflectors. |
6 |
EULUMDAT
photometric files :: In addition
to the other formats already supported,
Photopia now creates one of the most commonly
used formats in Europe. |
7 |
Illuminance
planes :: ability to display
and manipulate illuminance planes in the
CAD view makes them simple to use. Additionally,
illuminace planes can now accumulate light
inside a luminaire. This new approach allows
Photopia to model the effects of luminaires
within an arbirtrary shaped room including
non-diffuse materials assigned to room
surfaces, something radiosity-based rendering
programs cannot match. The illuminance
planes also now support Target Efficiency. |
8 |
Multiple
lamp types :: Photopia now accepts
multiple lamp types per design. |
9 |
International
plot styles :: new polar plots
include options for full plane plots
and primary planes only.
|
10 |
Lumen
Summary statistics :: in addition
to the number of lumens absorbed on each
layer and material, Photopia will now report
the number of lumens incident upon the
layers and materials. This allows the number
of lumens incident onto a clear bulb to
be tracked, for example. |
