pack_gpu_components()

MAYAFLUX_API bool MayaFlux::Kakshya::pack_gpu_components ( GpuDataFormat  dst, std::span< const double >  components, std::span< std::byte >  out  )

noexcept

Writes scalar components into out as one element of dst.

Each component is converted to the component type of dst. Integer destinations saturate and map NaN to zero.

Parameters

dst	Destination format.
components	Source components, in element order (column-major for MAT4_F32).
out	Destination bytes, at least gpu_data_format_bytes(dst).

Returns

False, with out untouched, if the component count does not equal gpu_data_format_components(dst) or out is too small.
