This issue tracks progress on primitive shapes, which were first added in #10466 based on the primitive-shapes RFC.

Meshing #10569

Primitives should support Mesh construction.

• 2D shapes Add Meshable trait and implement meshing for 2D primitives #11431
• 3D shapes Implement Meshable for some 3D primitives #11688
• Deprecate shapes in bevy_render::mesh::shape Deprecate shapes in bevy_render::mesh::shape #11773
• Support subdivisions

Gizmos #10571

Gizmos should support drawing primitives.

• Drawing Primitives with Gizmos #11072

Bounding volumes #10570

Bevy should have first-party bounding volumes and support computing them for primitives.

• Implement bounding volume types #10946
• Implement bounding volumes for primitive shapes #11336
• Implement bounding volume intersections #11439
• Add RayTest2d and RayTest3d #11310
• Add volume cast intersection tests #11586

• Ray casting Ray Casting for Primitive Shapes #15724
• Support maps
• Signed distance functions

Long-term possibilities

• Bounding Volume Hierarchies (BVH)
  • Broad phase collision detection
  • Spatial query pipeline
  • Rendering
• Frustum culling
• Collider shapes and collision detection for primitives
• Raycasting and other spatial queries for primitives
• Signed Distance Functions (SDF) for primitives
