I have a custom c++ dat that I store double data in via the sdk. However, I cannot seem to sort how to access these values via python or in another op. If I do text it’s fine but it doesn’t seem to be able to access the numerical values. I’d prefer to avoid the conversion to a string.
If you want to avoid conversions to string then you’d need to use the CPython API workflow to create Python members/methods in your custom operator, so you can directly pass the data as 64-bit doubles between the C++ code and Python. Look at the Samples\CPlusPlus\CHOPWithPythonClass directory located in the installation directory.
Parameters store/output values as doubles as well, so you can safely evaluate your Python expression in a parameter and the 64-bit data will be maintained. It will get reduced to 32-floats inside most nodes though for their operations though (CHOPs, GLSL uniforms etc.)
