b07f9446c7 Hopefully last change to matrix orthogonal check, touches Py API only
- is_orthogonal now checks matrix in the same way as it's defined
  by linear algebra, meaning that it'll use is_orhonormal C check
- Added is_orthogonal_axis_vectors to check if vectors which defines
  axises are orthogonal

26b0255049 Fix for is_orthogonal check which in fact was checking for orthonormal matrix.
Separated it into two functions so now it'll be clear if check happens for
orthonormal or just orthogonal.

89b83f0060 patch to add __deepcopy__ to mathutils types, this is no different to __copy__, except some py utilities expect __deepcopy__ to exist, so better have them. 2012-03-30 11:35:58 +00:00

7f1e9b8c41 bmesh py api:
added access to deform weights, access to weights acts like a python dict so you can do...

  print(group in dvert)
  dvert[group] = 0.5
  print(dvert[group])
  del dvert[group]
  print(dvert.items())

ee9a00948b mathutils py api:
Vector.angle_signed(other)
  for 2D vectors to get the clockwise angle between them.

  in BLI math its called - angle_signed_v2v2()

shorthand for...

  atan2f((v1[1] * v2[0]) - (v1[0] * v2[1]), dot_v2v2(v1, v2))

also corrects compile error in last commit.

8646bb4464 workaround [#30480] Knife tool flicker
the problem was numeric precision when in ortho mode the start/end points for the view vector would be 2000 apart which caused trouble for the intersection test.

5a221dd0de Fix for possible memory leak on creation of a vector using Vector.Range.
It was possible to allocate an array of size<2 which would then raise an error on vector creation without freeing.

Fix to ensure the behaviour of Vector.Range was the same as for builtin range() function. When specifying 3 arguments, the step argument wasn't being used to correctly calculate the vector size.

Minor formatting edits for error messages.

40f1686f47 Fixes to Python matrices str function.
1) The width of columns was incorrectly determined on windows, fixed by increasing the size of the dummy buf.
2) Added additional brackets to string for consistent formatting

e634cb2607 Add the .Identity() classmethod to mathutils matrices. This allows the user
to create an identity matrix of a specific size without having to specify
all the values in the matrix and then use the .identity() method.

2a80368005 mathtils, convenience attributes added 'row' and 'col', this makes the row/col swap a lot easier to deal with, since
now you can still use column access

previously...
  mat[2] = 1, 2, 3

needed to be converted into...
  mat[0][2] = 1
  mat[1][2] = 2
  mat[2][2] = 3

but with column access you can do...
  mat.col[2] = 1, 2, 3


Having 'row' attribute is a bit redundant since direct indexing on a matrix uses row but included for completeness.

Scripts which access matrix row/columns directly and scripts that create new matrices with elements defined will need updating.
