Mesh Prim Equivalence test

Purpose

Test the prim equivalence of mesh objects. (See Mesh for Mesh feature details)

Test Plan

Verify upload window prim equivalent matches in-world prim equivalent

• Upload a model (Build menu > Upload > Model) and choose duck.dae. (from https://collada.org/owl/browse.php?sess=0&parent=126&expand=1&order=name&curview=0)
• Click the Generate LOD button
• Look at the Model upload window and note the prim equivalent for the model. There's only streaming cost right now, in build 2.2.1 (210955).
• Click the Upload button, wait for the duck to upload, and rez the duck on the ground.
• Edit the duck
• Verify the prim equivalent in the edit window matches the upload window.

Verify in-world prim equivalent matches edit tool prim equivalent

• Right-click the parcel and choose About Land from the context menu.
• Open the Objects tab of the window and note the Prims on parcel
• Rez the duck on the parcel
• Right-click the parcel and choose About Land from the context menu.
• Open the Objects tab of the window and note how much the Prims on parcel has increased.
• Edit the duck
• Verify the prim equivalent in the edit window matches the increase in the Prims on parcel.

Scaling a mesh changes its prim equivalent

• Set the object physics to Mesh
• Scale the mesh up
• Verify the prim equivalence decreases
• Scale the mesh down
• Verify the prim equivalence increases

Scaling a mesh using Hull does not change its prim equivalent

• Set the object physics to Hull
• Scale the mesh up and down
• Verify the prim equivalent remains the same at all scales.

Appears that prim equivalency drops to 1.0 if 2 of the dimensions are less than 0.2m. Is this the expected behavior?

Scaling a mesh can cause object returns

• Set the object physics to Prim
• Scale a mesh down and deselect it.
• If the mesh's prim count exceeds available prims, return objects in the correct order
  • Return order:
  • objects not owned by the parcel owner (note: parcel owner may be a group)
    • from newest to oldest, by time they were last rezzed or modified (note: there is no way to see this 'last modified time' via the viewer)
  • objects owned by the parcel owner (note: this may be a group)
    • from newest to oldest, by time they were last rezzed or modified
    • Expect that of all the parcel owner's objects, only the mesh should return. Any change made to the mesh to increase its mesh equivalence (changing physics shape, dropping a new mesh shape, scaling down, unlinking) should cause the mesh to be flagged as the most recently modified object.

• If the mesh's prim count exceeds region limit, return the mesh when it is deselected.
  • Can the mesh be rezzed again long enough to be corrected?
  • Can the mesh be attached?
    • What happens if you drop it on the ground?

Verify parcel prim limits are correct after parcel operations

• subdivide parcel
• join parcels
• sell parcel
• sell objects with parcel
• deed parcel to group
• reclaim parcel by the estate owner
• force ownership by administrator

Temporary objects

• Temporary objects do not count toward the parcel object limit
• Temporary objects do count against the sim prim limit

Temporary meshes

• Temporary objects do not count toward the parcel object limit ???
• Temporary objects do count against the sim prim limit ???

Objects as Vehicles

• Objects that an avatar is sitting on do not count toward the parcel object limit
• Objects that an avatar is sitting on do count against the sim prim limit

Meshes as Vehicles

• Meshes that an avatar is sitting on do not count toward the parcel object limit ???
• Meshes that an avatar is sitting on do count against the sim prim limit ???

Objects as Attachments

• Attachments do not count toward the parcel object limit

Meshes as Attachments

• Mesh attachments do not count toward the parcel object limit

Selected Objects

• Selected objects do not count toward the parcel prim limit
• Selected objects do count toward the sim prim limit ???

Selected Meshes

• Selected meshes do not count toward the parcel prim limit
• Selected meshes do count toward the sim prim limit ???
