All three vectors of OrientedPoint annotations have the same color

[uermel]

In the precomputed line-based visualization of OrientedPoint annotations, all three lines have the same color.

The expected behavior is that the lines are colored by the principle axis they represent (with the same color scheme Neuroglancer uses for the global axes).

See example. Source run.

Hi @uermel and @manasaV3,

This is bug is caused by the oriented points using the regular points shader. They should instead by using the OrientedPointsShaderBuilder, which result in the link above looking like this instead new link:

I think the most likely cause is that the JSON state generation for this layer in the portal backend is using the json.generator.AnnotationJSONGenerator class instead of the intended json.OrientedPointAnnotationJSONGenerator class. The oriented point generator is a subclass of the annotation generator, so hopefully it shouldn't be an issue to swap them - but if something is blocking that please let us know! This would mean calling state_generator.generate_oriented_point_layer instead of state_generator.generate_point_layer.
