ALTA  alpha
data_merl Class Reference

## Detailed Description

This plugin enables to load data measurments from the Mitsubishi Electric Research Laboratories. This dataset contains 100 reflectance samples acquired from painted spheres using an imaging system.

The data is stored as RGB tuples in the RUSIN_TH_TD_PD isotropic parametrization. A non-linear transformation of the first component is used to improve the storage of specular materials. The resolution is 90 samples for $$\theta_H$$ and $$\theta_D$$ and 360 samples for $$\phi_D$$

Note that this plugin is not compatible with the anisotropic measurments of Ngan et al. [2005].
