Cannot make flat arrows #140

Open jhurliman opened 8 months ago

jhurliman commented 8 months ago

Description

With ROS arrow markers, you can set size to {1, 1, 0.01} to get a flat arrow. There doesn't seem to be any way to replicate this with SceneEntity arrows.

Are you not able to set head_length to 0? https://docs.foxglove.dev/docs/visualization/message-schemas/arrow-primitive/

What is a "flat arrow"? Like only the head?

jhurliman commented 8 months ago

Unfortunately, no combination of those two values will produce an arrow that looks like this (ignore the bevels):

Is that a screenshot of the arrow you get from the ROS arrow marker or the ArrowPrimitive?

jhurliman commented 8 months ago

It's a random image I found online that shows a flat arrow, in the same style that the ROS arrow marker can produce. This type of style cannot be replicated with an ArrowPrimitive because you can only control head/shaft length and diameter, you can't resize per 3d axis.

Gotcha. Thanks for the additional context. I'm gonna move this to feature cause our current arrow primitive is designed for making (volumetric?) arrows rather than trying to be a 1:1 copy of the ROS Marker message.
