Code metrics (dev branch) :
cacao is a computation engine for adaptive optics control.
Compute Performance: Uses multi-core CPUs and GPGPUs for high computing throughput. Written in C, optimized for performance. Holds images in RAM, with image stream support (shared memory with low-latency IPC support). cacao uses milk.
User input: Executable launches a command line interface (CLI) from which functions are accessible. Type "help" in the CLI to get started.
Modular, easy to add functions, loaded at runtime as shared objects.

Install pre-requisite packages as needed. For example, under Ubuntu :
sudo apt install git make dpkg-dev libc6-dev cmake pkg-config python3-dev libcfitsio-dev pybind11-dev python3-pybind11 libgsl-dev libfftw3-dev libncurses-dev libbison-dev libfl-dev libreadline-dev pkg-config gcc-10 g++-10
cacao is a plugin of milk page.
git clone https://github.com/milk-org/milk.git
cd milk
./fetch_cacao_dev.sh
MILK_PYTHON="OFF" ./compile.sh
cd _build; sudo make install
Check compilation options with compile.sh -h option.
See cacao's wiki page for detailed instructions to install, configure and use cacao.
All functions are accessible from the command line interface (CLI). Enter the CLI and type "help" for instructions.
cacao
To set up a cacao AO loop, use the cacao-setup script. Consult help with :
cacao-setup -h
Both cacao and milk use a common shared memory data stream format. See ImageStreamIO module for details.
Additional software is required to view real-time data streams. Several options exist:
- shmimviewGTK, a lightweight efficient GTK-based viewer.
- milk2ds9 uses ds9 to view data streams (convenient for ds9 users)
- rtimv, a qt-based image viewer, higher performance than ds9 option
- shmimviewqt, another qt-based option (less polished than rtimv)
- xaosim's shmview image viewer, using python qt interface
Python users can read/write milk/cacao's data streams using additional packages:
- pyMilk provides an interface to data streams.
- xaosim includes a python interface to data streams.. and much more Both stream interfaces above are cross-compatible.
