Description

Originally reported by: chummels (Bitbucket: chummels, GitHub: chummels)

  • Make annotate_ray() optionally overplot an arrowhead on the ray for illustration of directionality

  • Include vector attribute on OrthoRay and Ray objects

  • Allow easy creation of LightRay objects from OrthoRay and Ray objects with a method for automatically doing this.

  • Make annotate_ray callback in new VR interface using LineSource

Contributor guide

Research direction
Study the existing Ray and OrthoRay classes in yt/geometry/geometry utils.py to understand their current attributes and methods. Then implement the vector attribute and the annotate ray arrowhead option. For LightRay creation, examine the yt/analysis modules/cosmological observation/light ray.py module to see how to integrate.
