Extract drjit value in C++

[hsunekichi]

Hi.
Is there some function equivalent to ArrayBase.numpy() in C++ that allows to extract the array values, either to C++ scalars or something like Eigen?

Thanks for the help.

Hello @hsunekichi,

There's no Eigen-specific interoperability that I am aware of, however you should be able to use cpu_jit_array = dr::migrate(your_jit_array, AllocType::Host) to ensure that the data is on the host, and then map the data pointer however you like (cpu_jit_array.data()).

It works, thanks!
