The PR is in a reviewable state now in the sense that the basic implementations are there. There are still some ToDos that I'm aware of: - [x] docs for all the new structs and traits - [x] implement `Default` and derive other useful traits for the new structs - [x] Take a look at the notes again (Do this after a first round of reviews) - [x] Take care of the repetition in the circle drawing functions --- # Objective - TLDR: This PR enables us to quickly draw all the newly added primitives from `bevy_math` in immediate mode with gizmos - Addresses #10571 ## Solution - This implements the first design idea I had that covered everything that was mentioned in the Issue https://github.com/bevyengine/bevy/issues/10571#issuecomment-1863646197 --- ## Caveats - I added the `Primitive(2/3)d` impls for `Direction(2/3)d` to make them work with the current solution. We could impose less strict requirements for the gizmoable objects and remove the impls afterwards if the community doesn't like the current approach. --- ## Changelog - implement capabilities to draw ellipses on the gizmo in general (this was required to have some code which is able to draw the ellipse primitive) - refactored circle drawing code to use the more general ellipse drawing code to keep code duplication low - implement `Primitive2d` for `Direction2d` and impl `Primitive3d` for `Direction3d` - implement trait to draw primitives with specialized details with gizmos - `GizmoPrimitive2d` for all the 2D primitives - `GizmoPrimitive3d` for all the 3D primitives - (question while writing this: Does it actually matter if we split this in 2D and 3D? I guess it could be useful in the future if we do something based on the main rendering mode even though atm it's kinda useless) --- --------- Co-authored-by: nothendev <borodinov.ilya@gmail.com> |
