What was needed to port it from 2.49 -> 2.50 alpha 0?
|
||||
|
||||
The basic functions that calculate the geometry (verts and faces) are unchanged
|
||||
( add_tooth(), add_spoke2(), add_gear() )
|
||||
|
||||
These functions were designed to return lists of tuples (x,y,z) (for the vertices) and
|
||||
lists of lists [i,k,l,m] (for the faces). Because the Blender 2.50 API does not provide
|
||||
facilties to alter individual elements of the the verts and faces attributes of a mesh
|
||||
directly we have to add the calculated vertices and faces in bulk by using the
|
||||
mesh.add_geometry(nverts,nedges,nfaces) methodfolowed by
|
||||
mesh.verts.foreach_set("co", verts_loc) and mesh.faces.foreach_set("verts_raw", faces).
|
||||
|
||||
Both the foreach_set() methods take flattened lists as arguments, not lists of tuples, so we
|
||||
added a simple function to flatten a list of lists or tuples.
|
||||
|
||||
Also, the vertex group API is changed a little bit but the concepts are the same:
|
||||
vertexgroup = ob.add_vertex_group('NAME_OF_VERTEXGROUP') # add a vertex group
|
||||
for i in vertexgroup_vertex_indices:
|
||||
ob.add_vertex_to_group(i, vertexgroup, weight, 'ADD')
|
||||
|
||||
Now for some reason the name does not 'stick' and we have to set it this way:
|
||||
vertexgroup.name = 'NAME_OF_VERTEXGROUP'
|
||||
|
||||
Conversion to 2.50 also meant we could simply do away with our crude user interface.
|
||||
Just definining the appropriate properties in the AddGear() operator will display the
|
||||
properties in the Blender GUI with the added benefit of making it interactive: changing
|
||||
a property will redo the AddGear() operator providing the user with instant feedback.
|
||||
|
||||
FInally we had to convert/throw away some print statements to print functions as Blender
|
||||
nows uses Python 3.x
|
||||
|
||||
The most puzzling issue was that the built in Python zip() function changed its behavior.
|
||||
In 3.x it returns a zip object (that can be iterated over) instead of a list of tuples. This meant
|
||||
we could no longer use deepcopy(zip(...)) but had to convert the zip object to a list of tuples
|
||||
first.
|
||||
|
||||
The code to actually implement the AddGear() function is mostly copied from add_mesh_torus()
|
||||
(distributed with Blender).
|
||||
|
||||
Unresolved issues:
|
||||
|
||||
- removing doubles:
|
||||
the code that produces the teeth of the gears produces some duplicate vertices. The original
|
||||
script just called remove_doubles() but if we do that in 2.50 we have a problem. To apply
|
||||
the bpy.ops.mesh.remove_doubles() operator we have to change to edit mode. The moment
|
||||
we do that we loose to possibilty to interactively change the properties. Also changing back
|
||||
to object mode raises a strange exception (to investigate). So for now, removing doubles is left
|
||||
to the user once satisfied with the chosen setting for a gear,
|
||||
|
||||
- no suitable icon:
|
||||
a rather minor point but I reused the torus icon for the add->mesh->gear menu entry as there
|
||||
doesn't seem to be a generic mesh icon or a way to add custom icons. Too bad, but as this is
|
||||
just eye candy it's no big deal.
