Mesh Import test

Purpose

Test all functionality of the Mesh Import window. (See Mesh for Mesh feature details)

Test Plan

Uploading a Mesh

• Open the inventory, click the + menu button and Upload > "Model."
  • Alternatively, use the build menu (Build > Upload > Model)
• Verify a File Dialog Box opens
• On Windows, 3D scene/UI should continue to update while file dialog box is open.
• Pick a .DAE file from your computer. (or try duck.dae from https://collada.org/owl/browse.php?sess=0&parent=126&expand=1&order=name&curview=0)
• Verify the Import Model window appears.
• Verify in the High LOD text box information about the file appears such as triangles and submeshes.
• The model should be presented in a mini window and "spinnable" using the same mouse and keyboard commands as "spinning" around objects in-world.
• Verify Import Model window does not block you from accessing Second Life (chat, inventory, etc).
• (Not implemented as of 2010-8-31) Verify the Import window lists the number of prim equivalents the mesh is and how much it will cost in L$.

Generate LOD button

• Hit the Generate LOD button.
• Verify the High, medium, low, lowest LODs, and Physical Shape should now contain triangle, vertex, and submesh info.

Generate Normals button

• Set the preview box to Medium.
• Hit the Generate Normals button.
• Verify the model preview becomes more faceted.

Hard Angle

• Change the Hard Angle to 1.
• Click "Generate Normals".
• Verify nearly every polygon on the face should be apparent.

High LOD

• Next to High LOD, click "Choose a file..."
• Verify a file chooser opens
• Choose a different model.
• Set the preview window to High
• Verify the model you chose shows up in the preview window.
• (Not implemented as of 2010-8-31) Verify the Import window lists the number of prim equivalents the mesh is and how much it will cost in L$.
• Click Triangle limit. Enter 64 as a value.
• (Not implemented as of 2010-8-31) Verify the Import window lists the number of prim equivalents the mesh is and how much it will cost in L$.
• Verify the model's detail has decreased in the preview window
• (Add a test to exercise the maximum model size)

Medium LOD

• Choose a file. Verify that when preview window is set to medium, it shows up in the preview window.
• Click Triangle limit. Enter 64 as a value.
• Verify the model detail has decreased in the preview window

Low LOD

• Choose a file. Verify that when preview window is set to low, it shows up in the preview window.
• Click Triangle limit. Enter 64 as a value.
• Verify the model detail has decreased in the preview window

Physical LOD

• Choose a file. Verify that when preview window is set to Physics, it shows up in the preview window.
• Click Triangle limit. Enter 64 as a value.
• Verify the model detail has decreased in the preview window
• Does this have a maximum value?

LoD criteria enforcement

• Source as of Aug 16, 2010: http://blogs.secondlife.com/message/353310
• The prim cost will be 1 prim for every 4KB in the high LoD. Will change to something like "The prim cost will be 1 prim for every 400 (or 256 or 128) triangles in the high LoD"
• Each LoD must be NO MORE than 50% the number of triangles of the next highest LoD. As of 2.1.1 (208871) viewer enforces 50% of KB instead of 50% of triangles. Viewer will need to change
• Any LoD that has less than 128 vertices will not be reduced.
• This cost is independent of physics cost, and the final cost of an object will be the mesh streaming cost OR the physics cost, whichever is greater

• Attempts to break these rules:
  • leave medium LOD blank. can i set low LOD to be 1/2 of high?
  • set medium LOD to the same model as high LOD?
  • set medium LOD to a model with more vertices than high LOD?
  • generate all LODs then lower the high LOD?
  • What if the object has several submeshes?
  • set physics mesh higher than High LOD mesh?

Description

• Verify you can change the description. Maximum string length?

Generate Normals button

• Tested above

Upload button

• Notice that there should be no cost to upload for First Look.
• Verify that the Upload button is unavailable if the LoD criteria rules are not met.
• Verify that the Upload button becomes available when the LoD criteria rules are met.
• Click the Upload button.
• Verify at least one mesh shape and one object is uploaded to your inventory.
• Verify the object has the description you entered earlier.

Scrub Materials button

• Click the Scrub Materials button and verify the model changes from gray to white.

Consolidate button

• Upload a file that has several submeshes (something similar to connery.dae)
• Click the Consolidate button
• Verify the submeshes has changed to 2. (because there are 2 materials or colors in the object)
• Click the Scrub Materials button
• Click the Consolidate button
• Verify the submeshes has changed to 1. (because there is only 1 material now)
• Close the Mesh Upload window without uploading.
• Upload a model with more than 64k vertices (need a model)
• Click the Scrub Materials button.
• Click the Consolidate button.
• Verify the submeshes is 2 or greater. (because there is 1 mesh for every 64k vertices)

Physics Decomposition window

• Upload duck.dae
• Verify the ‘>>’ button next to “Physical Shape” is unavailable.
• Click the drop down menu next to "Physical Shape:" and set the triangle limit to 4212
• Verify the ‘>>’ button next to “Physical Shape” is now available.
• Click the ‘>>’ button next to “Physical Shape” to open the Physics Decomposition window.
• Verify a window opens that has Decompose and Simplify buttons.
• Click Cancel to close the Physics Decomposition window.
• Click the Decompose button
• Uncheck the Mesh checkbox
• Verify the model preview shows the model is broken into pieces of different colors.

Top section

• Mesh checkbox
• Hull checkbox
• 'Drop down menu #1' Submesh drop down? What's the name of this drop down?

Stage 1 - Decomposition

These all need definitions and tests

• Cosine %
• Simplify Coplanar
• Close Holes (Slow)
• 'Drop down menu #2'
  • Preview
  • Normal
  • High
• 'Drop down menu #3'
  • Surface
  • Solid
  • Wrap
  • Delaunay (menu cuts off text when selected)
• Decompose button

Stage 2 - Simplification

These all need definitions and tests

• Combine Quality
• Detail Scale
• Retain%
• 'Drop down menu #4'
  • Retain%
  • Best
  • Better Detail
• Simplify button

Bottom section

• Status (bug: status does not initialize if you reopen the decomposition window)
• Cancel button

Explode slider

• After decomposing a model, move the Explode slider.
• Verify the decomposed pieces of the model move away from each other as the Explode slider is moved to the right.

Choose File...

• Are there any limitations here? Does LoD criteria enforcement come into play?

Show Edges

• Check the Show Edge checkbox and verify that the Preview shows the edges of the triangles.
• Uncheck the Show Edge checkbox and verify that the triangles edges are no longer highlighted in the Preview window.

Preview window

• Verify you can zoom in/out on the model and rotate it right and left with mouse drag.
• Verify you can rotate the model up and down with ctrl + mouse drag.
• Verify you can pan the model with ctrl + shift + mouse drag. (should this work? works a little. Only small movements...)

Upload Textures option

• Not implemented at this time?

Upload a rigged object

• Download http://jira.secondlife.com/secure/attachment/38659/simplebot.dae
• Upload the mesh
• Verify generate normals does nothing unexpected.
• Verify LOD generation does nothing unexpected.
• Walk around and Verify the rigged object animates in the preview window.
• Verify "consolidate" is grayed out.
• Upload the mesh
• Verify a mesh and an object are uploaded.

Upload a bad object

• Test uploading a bad object (need example object)
• Verify sufficient error is returned.
  • Need a test for each error type.
