set_data() [1/4]

void MayaFlux::Buffers::AudioWriteProcessor::set_data

(

const Kakshya::DataVariant &

variant

)

Supply data from any DataVariant — converted to double via EigenAccess.

Parameters

variant

Source variant. Arithmetic/complex types: converted via EigenAccess::to_vector() (complex uses magnitude). GLM vector/matrix types: converted via EigenAccess::to_matrix(), then flattened column-major: [x0,y0,z0, x1,y1,z1, ...].

EigenAccess::to_matrix() flattens glm types into a components-as-rows MatrixXd. Flatten column-major into a double sequence: [x0,y0,z0, x1,y1,z1, ...]

Map column-major layout directly — Eigen default is column-major.

Arithmetic and complex types: to_vector() handles magnitude for complex.
