Fibonacci Spiral Vector and Warp Fields

[joyhughes]

Create a spiral vector field such that advecting from any point will produce a Fibonacci spiral. This will be used in the Kaleidoswirl scene ( issue #140 ) and for targeting warps in cellular automata.

@joyhughes would like to work on it as a problem solving enthusiast under gssoc'24 but need to know whether you want just the c++ implementation of the field or smt else?

hello sir, can you assign this issue to me. I have started work on it.

It is C++ implementation of vector field as well as creating an effect that can be stored in the scene, and a scene file for testing.

Interesting! What have you done so far?

i have the complete code ready in c++ please tell me how it needs to be added just

If it is ready just submit PR

[kairveeehh]

no I mean I have a c++ code that works on input /output based ready , can share or create a PR of the same but I need you to explain how it needs to be added

I'm interested in seeing what you've written so far.

Calculations for vector fields happen in the vftools class in vector_field.cpp ... then an effect functor in effect.cpp with harness functors for each parameter that can be changed. A smart pointer to the effect functor needs to be added to the variant any_effect_fn_ptr in any_effect.hpp and a line for loading the function needs to go into scene_io.cpp. The kaleido.json scene file can be modified to test.

If you learn how to do this one time there will be multiple issues with the same general format - writing a function or effect, adding to the variants and I/O and testing in a scene file.

Yea this was what i needed right now I have a c++ code that generates a Fibonacci spiral upon execution will add it to Pr

Did you have a chance to take a look at it?

yea I did but I want to ask that I am just adding a c++ code right now is that fine ?

[joyhughes]

Yes I can handle the scene file JSON
