Wings 3D

File Release Notes and Changelog

Release Name: 1.1.1

Notes:
- The data structure for the vertex tables has been changed.
  (There is one vertex table to keep track of the vertex positions,
  and another vertex table used for finding edges and face around
  the vertex.) The new data structure is faster and uses less memory.
  [bjorng]

- When displaying vertices and edges, a feature in OpenGL called vertex
  arrays is used to faster transfer the data from Wings into OpenGL.
  This way of displaying geometry is slightly faster than the previous
  method. [dgud, bjorng]

- ESDL updated to 1.0.1. (The next release in the 1.1 series will probably
  not work without that version of ESDL.) [bjorng]

- Magnets are now drawn correctly in Tweak when selections across multiple
  objects are dragged. [optigon]

- Selectings multiple objects in Tweak and calling a command via a hotkey would
  only affect one of the objects. Now corrected. [optigon]

- Crash reported by Fonte Boa corrected. [optigon]

- Tweak mode temporary selection fix. [optigon]

    Fix crash in Aim when targeting unselected geometry.
    
    Bjorn's change to save the last command executed in #st.last_cmd
    assumed that command/2 always was called with a #st{} record
    as the second argument. That was not so. Aiming at unselected
    geometry (if turned on in the preferences), would construct
    a second argument looking like {add,St0,St} or {delete,St0,St}.
    
    I have changed that to send the extra information in the command
    itself. There is also no need to send the entire St, since only
    the selection is used.

    Clean up of code for Flip.
    
    All kinds of Flips are now used with a matrix and wings_we:transform_vs/2,
    making the code clearer and more compact.

    Use arrays instead of gb_trees for the vertex tables.
    
    Both the #we.vc and #we.vp tables are now arrays instead of
    gb_trees. For each table, about 4 words per entry will be
    saved.

    Added a picture of a winged-edge.
    
    It should have been there from the beginning!

    Vertex arrays for edges and points.
    
    Next step is faces and later reuse the vertex array.

    Optimized drawing of edges.
    
    My optimized version does not build temporary binaries for
    each tri or quad.
    
    Measurements on my Mac:
    
    Before this optimization, using vertex arrays was somewhat slower
    than the old way of drawing edges.
    
    After this optimization, using vertex array is almost twice as fast
    as the old way.

    Use vertex arrays instead of the wpc_ogla driver.
    
    I do this because we need to get rid of wpc_ogla if we
    want to use wxerlang later so it part of that port.
    The performance seems to be the about same.

    Add more types in records and eliminate Dialyzer warnings.
    
    Notes:
    
    AutoUV uses #st.bb and #we.name for its own purposes,
    so types must allow for that. (For now.)
    
    erlang:make_tuple/3 is not known by Dialyzer in R13B.
    It turns out that the code in wings_undo that used
    make_tuple/3 can be made shorter and more maintainable
    by using record_info/2.
    
    The field #we.saved is re-used for storing an image index
    in an ugly way.

    temp selection wasn't clearing on new_state within Tweak mode

    Not rebuilding the edge table when extruding single faces.
    
    Here is another case when there was previous optimization
    of not updating the edge table directly, but instead collecting
    new edges into a list, and rebuilding the gb_tree for the edge
    table at the end.
    
    Directly updating the edge array is simpler, slightly faster,
    and requires less memory in the undo queue (especially when
    extruding only a few faces from a huge object).

    Error handling for unknown I/O requests was incorrect.
    
    Simply fixing the original problem would only make it
    difficult to find the real problem from wings_crash.dump
    if/when the I/O protocol is extended in a future Erlang/OTP
    release. Therefore we ignore the request, but log it to
    the console itself.

    Operate directly on the edge table.
    
    When the edge table was a gb_tree, massive updates to the edge table
    was better done by first converting the gb_tree to an orddict, work
    on it, and convert back.
    
    For an array, it is better to operate directly on the array to
    increase sharing between undo states.
    
    The speed is about the same, perhaps slightly slower. I choose to do
    this change because the code is simpler and not converting the edge
    array to an orddict and back will increase sharing between undo states
    when smoothing part of the object in face mode (in body mode, all of
    the edge table will be updated anyway).
