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.

9a37e2682d slice and iterator access for matrix.col/row so you can do... 
a, b = mat.col[0:2]

  and...

5c8c1a7358 PyAPI - remove Matrix.row_size / col_size. these were rather awkwardly named, but its more clear to use len(). 
mat.col_size --> len(mat.row)
mat.row_size --> len(mat.col)

986e62f3b6 fix for a bug in mathutils when a vector was accessing a matrix and the matrix size increased, future access too the vector would write past the allocated bounds. now raise an exception. 2011-12-26 00:05:41 +00:00

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.

89db50a712 patch [#29534] Change Matrix Representation and Access in Python to Conform with Standard Notation 
from Andrew Hale

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

840dfcd56d cleanup and some fixes to mathutils by Andrew Hale 
* 1. Resize 4x4, code was ridiculously complex (cleanup only)
* 2. matrix * matrix checking for compatibility wasn't working right (bug in last release)
* 3. fix for result size for matrix * vector if matrix is 4x4 and vector size 3 (bug in recent patch)
* 4. fix for result size vector * matrix if matrix is 4x4 and vector size 3 (bug in recent patch)

0bc83a2f35 - mathutils matrix creation - use memcpy rather than copying every matrix row/col individually. 
- creating a new non-square matrix would use uninitialized memory.

c3675c0e90 remove mathutils internal variable for storing pointers to each matrix row, instead use macros to access row/column's. 
also add an assert so invalid index access will raise an error in debug mode, without this it was quite easy to access invalid memory without meaning to.

no functional change.

c62d33c540 patch: [#29382] Arbitrary Length Array Function Additions and Modifications 
from Andrew Hale (trumanblending), with some edits to use these in mathutils.Vector added.

Added Functions:
- dot_vn_vn - Dot product of two arrays
- normalize_vn_vn - Normalize an array and store the result in a second array
- normalize_vn - Normalize an array inplace

Renamed Functions:
Some functions have been renamed to make them consistent with the naming conventions used by fixed length array functions.
- fill_vni to fill_vn_i
- fill_vn to fill_vn_fl

9d3b1f708f Move function out of mathutils to: BLI_math_rotation --- single_axis_angle_to_mat3(mat3, axis, angle), copied out from mathutils, axis arg is a char 'X/Y/Z' rather then a vector like axis_angle_to_mat3(). 2011-09-19 13:08:01 +00:00

ced8f1dffc deprecate multiplication orders: 
vector * matrix
 vector *= matrix
 vector * quaternion
 vector *= quaternion 

Use the reverse order instead, enable WITH_ASSERT_ABORT in cmake to promote the warnings into errors.

314fdb941e revert recent matrix multiplication patch: 
[#28032] Python Mathutils: Matrix Multiplication Error

Since they ended up reversing the order we better keep old code unless its proven to be incorrect.
also change Matrix.__repr__ function args to evaluate correctly (need to be inside a tuple).
