Abstract interface for a buffer of BSDF values.

pure virtual |
Returns the memory block containing the actual BSDF values.
The size of the array is given by
where res_phi is the value returned by mi::neuraylib::IBsdf_isotropic_data::get_resolution_phi(), res_theta is the value returned by mi::neuraylib::IBsdf_isotropic_data::get_resolution_theta(), and factor is 1 if mi::neuraylib::IBsdf_isotropic_data::get_type() returns mi::neuraylib::BSDF_SCALAR and 3 otherwise.
The index of the (first) element for a particular triple (index_theta_in, index_theta_out, index_phi_in) is given by
The pointer returned by this method has to be valid for the lifetime of this interface.
Implemented in mi::neuraylib::Bsdf_buffer.
