Plotting BRDF data from a CCD

Programs developped to exploit data from BRDF measurements using a ccd sensor

These programs were developped to exploit luminance or BRDF data from the EZ-Contrast instrument developped by Eldim. They are applicable to any measurment done using a ccd sensor.

The developped library includes:
- maxima research
- Polar zenithal plot of ccd sections
- Polar azimutal plot of ccd sections
- ccd zone restriction according to a zenithal angle.
- 3D sphere based representation.
- two samples .txt files from actual measurements, a diffuse standard and a glass sample.

The sphere based BRDF representation approximates whatr the visual system could perceive when gazing at the surface of an object.
