WV company a
graphics leader

IAN ASHDOWN, president of West Vancouver-based
byHeart Software Ltd., has a U.S. patent pending on a
novel laboratory instrument that is being called a major
advance i in lighting and computer graphics technology.

Ashdown - and Peter Murphy,
president of Langley-based
- Ledalite Architectural Products
Inc., were recently in San Diego,
California, to introduce a new
.. Way to measure and predict the
.. distribution of light surrounding a

’. lighting fixture.

With applications in architec-
tural and engineering fields, the
‘- goniophotometer will enable de-
- signers to develop lighting systems
that will result in reduced building

construction and energy consump-

tion.costs.
‘Based: on an . updated light
Measurement theory and new
calculation techniques, the
‘ (goniophotometer uses a high-tech
«television camera to measure the
‘. three-dimensional field of. light
surrounding a given lighting fix-
ture.
. ‘The approach allows computer
programs substantially increased
accuracy when designing lighting

systems.
Said ‘Ashdown, “The new pro-
cess also has applications in com-
puter graphics, where it can be
‘used. ‘in ‘architectural modelling
software programs and virtual re-
systems to improve the real-
-of onsputer-generated im-

P ed Somputer programs
that | enable architects and
engineers to see’ visually on screen

how their designs will look have
been hampered by light measure-
ment results that may be as much
as 30% wrong...

“This situation meant that the
professionals could not have
complete confidence as to how
their designs would illuminate in-
terior spaces such as offices and
building foyers,’’

. While in San Diego, Ashdown
presented a technical paper on his
research work in the field to
members of the Illuminating
Engineering Society of North
America.
