Textured Glass | Printed Casted Machined Glass | Volumic modeling
This case study is about glass with a texture, as a relief of various height. This type of texture ar typical of printed glass (or pattern cast).
They can also be obtained by casting them on a mold which has the negative of the desired texture or by maching directly the glass with a CNC machine.

Fig B | texture oriented verticaly | vavious glass pattern
Fig D| texture oriented horizontaly | interior view | blue sky
In this case, to keep the most accurate feedback, the glass has been fully modelled in 3D with the “texture” to take in consideration the refraction of the glass which has a strong influence on the optical behavior in this specific context .
Depending on the “texture” and its orientation toward the sky and surounding landscape, the glass behave very differently within the same facade orientation and depending of the view angle of the observer.
It appears dark with some acquired colored tint at certain time of the day or bright with some new tint at another .This variability will also by dependant on the view angle, very close of the behavior of a dichoic coating or a spectral paint .
This property is typical of any uncoated glass though the reflection property, but these examples shows that it can be designed, through the geometry of the pattern and its orientation within a specific environment.
The great asset of such optical behavior based on reflection is that is independant of the sky type. In other words, the results are most of the time as compelling with an overcast than a blue sky and even better with a cloudy and dark sky.
