Color is the sensation on the eye
produced by an object under the influence of a ray light. ThatÂ’s why we
developed these innovative tools, to let you know the exact color you will
obtain wherever light is.
For this, a new software application has been
developed.
Colorimetry is a standalone application
software fully compatible with our range of software, SPEOS/Photometry, SPEOS/Photorealism
and SPEOS/Scene Maker. It is the perfect complementary tool for obtaining exact
spectral information inside any result. Anywhere you point the mouse, you will
be informed interactively, with a tri-chromatic display and the spectrum
display. WhatÂ’s more, if your display system is calibrated, SPEOS/Colorimeter
will adapt the results for your screen !
HOW DOES SPEOS colorimetry work ?
Source definition
In Speos the source is characterised not only by its geo-metry and photometric
properties but also by its spectral radiation. The spectre is entered
interactively and graphically. You know the exact color of the radiation emit-ted
at all the times as well as its positionin the color triangle. A library of
spectres, B, C, D, F illuminants is provided to enable you to calibrate your
simulation “virtually”. In the spectre editor you can enter LED spectres as
well as other souces. The 3D interactive visualisation of sources also enables
you to materialise the thin beams of colored light which make up the source
emission.
Surface definition
In Speos, each surface is characterised by its roughness which determines the
way in which it reflects and diffuses the light which meets it. The light can be
transmitted (transparent materials), reflected (mirrors), diffused (plaster).
All these behaviours are ruled by different mathematical laws which have formed
the object of much research, giving you an easy method of entering the data
while conserving the most efficient models in the world. Optis has introduced
the innovative spectral behaviour which now allows us to take into account exact
color. You can also use optical treatment for thin films of your surfaces.
Material definition
As for the surfaces, Optis has pushed back the limits of traditional colorimetry
by developping behavioural models with wavelengths for material. Mass-colored
materials can now be simulated and thus make the association of colored filters
possible to find out the resulting color. Speos simulates the reduction of a
light beam during its propagation in a treated milieux. A milieux such as water
can be used and accurately modelled. The red will be absorbed faster than the
blue which will re-emerge like this in our colorimetric simulations
