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 Convex Hull mesh does not change its prim equivalent

Set a mesh object's physics to Convex 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? Falcon: Yes

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 (note: there is no way to see this 'rezzed 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

If the mesh's prim count exceeds region limit (15,000 for regular sims, 3750 for homesteads), return the mesh when it is deselected.
- Verify that rezzing the returned mesh returns it again.
- Verify you can attach the mesh, scale it up to 2x2x2m then drop it on the ground.

Unlinking a mesh can cause object returns

Link 2 meshes.
Set the physics shape of the child mesh to none.
Put objects on the parcel until it's prim limit is reached.
Unlink the mesh object
Verify that some of the objects that were added to the parcel to reach the prim limit are returned, because the mesh child object reverted to Physics shape Prim when unlinked.

Changing Physics shape of Root prim can overflow parcel

Link several torii together
Rez other prims or meshes on the parcel until the parcel prim limit is reached.
Edit the root prim of the torii linked set and set the Physics Shape Type to Convex Hull
Verify the Prim equivalent of the object increases. (?)

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 not count against the sim prim limit

Temporary meshes

Temporary Mesh objects do count toward the parcel object limit.
Temporary Mesh objects do count against the sim prim limit.

Mesh objects count against the Sim prim limit as only one prim. bug https://jira.secondlife.com/browse/SH-269, https://jira.secondlife.com/browse/SH-86

Objects as Vehicles

Objects that an avatar is sitting on do not count toward the parcel object limit. (They claim to count, and About Land claims that an object will be returned when the parcel prim limit is exceeded but an object is never returned)
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 (They claim to count, and About Land claims that an object will be returned when the parcel prim limit is exceeded but an object is never returned)
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
