Wings 3D

File Release Notes and Changelog

Release Name: 1.1.4.1

Notes:

- Having wireframe on and workmode off would cause a
  crash. (Thanks to Siber.) [bjorng]

- Select By|Vertices With could select hidden vertices
  (i.e. vertices surrounded only by hidden faces). Similarly,
  Select By|Random could select hidden edges or vertices,
  and Select By|Short Edges and Select By|Sharp Edges could
  select hidden edges. [bjorng]

- The Wavefront (OBJ) exporter will now export smoothing
  groups based on the hard edges in the model. [bjorng]

- For developers: There is a new module wings_va
  which is ultimately meant to encapsulate the details
  of how vertex attributes (i.e. vertex colors and UV
  coordinates) are stored. In this release, wings_va has
  an API mostly for retrieving vertex attributes (i.e.
  it does not yet handle updating of vertex attributes).
  In particular, all functions in wings_face that could
  retrieve vertex attributes (such as vinfo_ccw/2 and
  fold_vinfo/4) have been removed. [bjorng]

    Replace wings_face:vinfo_fold/4 with wings_va:fold/5
    
    There are several calls to wings_face:vinfo_fold/4 in
    wings_we:normals/2, but it turns out that they are
    not needed. wings_we:normals/2 used to return (for
    each vertex) both UV coordinates/vertex color and
    the normal, but all callers only match out the normal.
    
    Therefore, use wings_face:fold/4 instead of
    wings_va:fold/5, simplify the return value, and adjust
    all callers to handle the new return value. (The change
    in auv_texture cannot be tested, as there is currently
    no shader that requires normals.)

    New functions wings_va:face_attr/{3,4} to retrieve attributes
    
    These functions replace wings_face:vertex_info/{2,3} and
    similar functions.

    Add wings_va:info/2 to retrieve information about vertex attributes

    Start to move out #edge.a and #edge.b.
    
    I created a new module wings_va that will contain all operations
    on vertex attributes (vertex colors and UV coordinates).
    
    First I will keep the #edge.a and #edge.b fields, but isolate
    all operations in the wings_va module. I started with the
    Vertex Color commands in all four selection modes.

commit 105e718b10e034b9529f6a3df183cd118a284487

    Make wings_face:fold/4,5 vertex order consistent with other fold/info functions
    
    Compared to other fold and info functions (for instance,
    wings_face:fold_vinfo/4,5), the start vertex is different.
    For instance, if fold/4 gives the sequence 0, 1, 2, 3,
    then fold_vinfo/4 gives the 1, 2, 3, 0, which will result
    in wrong results if fold/4 is used to retrieve vertex
    positions and fold_vinfo/4 is used to retrieve UV
    coordinates or vertex colors.
    
    Change fold/4,5 to be consistent with the other functions.
    The rule is that the vertex nearest to the successor
    pointer should always be presented first (i.e. on the
    left side, use the "vs" vertex since it is nearest to the
    the "ltsu" pointer).
    
    This change seems to be safe after a quick look at the
    code.

    Let the Wavefront exporter export smoothing groups based on hard edges
    
    NOTE: The Wavefront (OBJ) exporter will now export smoothing
    groups based on the hard edges in the model. [bjorng]

    Make wings_sel:make/3 filter away invisible geometry automatically
    
    Also use 'rem' instead of floating point division and trunc/1
    to test for even or odd number of vertices.
    
    NOTE: Select By|Vertices With could select hidden vertices
    (i.e. vertices surrounded only by hidden faces). Similarly,
    Select By|Random could select hidden edges or vertices,
    and Select By|Short Edges and Select By|Sharp Edges could
    select hidden edges. [bjorng]

    Eliminate crash when wireframe mode and smooth mode are combined
    
    This bug was found by Dialyzer, but unfortunately only after
    the release of 1.1.4.
    
    NOTE: Having wireframe on and workmode off would cause a
    crash. (Thanks to Siber.) [bjorng]
