This page reference the different fitter plugins available in ALTA. A fitter plugin enables to perform regression of a BRDF model with respect to data measurments.
We list below all accessible fitter plugins in ALTA. To use one of those, please use the name referenced here. For example, to load and use the CERES nonlinear fitter use:
From the command line:
fitter nonlinear_fitter_ceres
In the Python Interface interface:
alta.get_fitter('nonlinear_fitter_ceres')
In a XML script:
<plugin type="fitter" name="nonlinear_fitter_ceres" />
