How to add multiple light sources?

[xopto]

Using multiple sources in a single Mc instance is not directly supported. However, there are at least two solutions for simulations with multiple sources.

1. (If all the sources are of the same type) Create one Mc instance and run the simulations sequentially (one simulation for each source configuration, update/change the source properties (e.g. position, direction, ...) before each simulation). Merge the individual simulation results. The merging/superposition will be trivial if all the simulations are run with an equal number of photon packets.
2. Create one Mc instance for each source and run the simulations independently. Merge the simulation results. The merging/superposition will be trivial if the simulations across all the Mc instances (sources) are run with an equal number of photon packets.
3. Create a custom source class by modifying one of the available sources. This solution is more complex as it requires both Python and OpenCL code.

The first or second solution will be easier to implement for multiple isotropic point sources.

Thank you very much for your response, so compared to solution 1 and 2, I am wondering if 3 would significantly reduce the simulation time?
