---------------------------------- Here's my changelog: -fixed Rand() so that it doesn't seed everytime and should generate better random numbers - changed a few error return types to something more appropriate - clean up of uninitialized variables & removal of unneccessary objects - NMesh returns wrapped vectors now - World returns wrapped matrices now - Object.getEuler() and Object.getBoundingBox() return Wrapped data when data is present - Object.getMatrix() returns wrapped data if it's worldspace, 'localspace' returns a new matrix - Vector, Euler, Mat, Quat, call all now internally wrap object without destroying internal datablocks - Removed memory allocation (unneeded) from all methods - Vector's resize methods are only applicable to new vectors not wrapped data. - Matrix(), Quat(), Euler(), Vector() now accepts ANY sequence list, including tuples, list, or a self object to copy - matrices accept multiple sequences - Fixed Slerp() so that it now works correctly values are clamped between 0 and 1 - Euler.rotate does internal rotation now - Slice assignment now works better for all types - Vector * Vector and Quat * Quat are defined and return the DOT product - Mat * Vec and Vec * Mat are defined now - Moved #includes to .c file from headers. Also fixed prototypes in mathutils - Added new helper functions for incref'ing to genutils - Major cleanup of header files includes - include Mathutils.h for access to math types - matrix.toQuat() and .toEuler() now fixed take appropriate matrix sizes - Matrix() with no parameters now returns an identity matrix by default not a zero matrix - printf() now prints with 6 digits instead of 4 - printf() now prints output with object descriptor - Matrices now support [x][y] assignment (e.g. matrix[x][y] = 5.4) - Matrix[index] = value now expectes a sequence not an integer. This will now set a ROW of the matrix through a sequence. index cannot go above the row size of the matrix. - slice operations on matrices work with sequences now (rows of the matrix) example: mymatrix[0:2] returns a list of 2 wrapped vectors with access to the matrix data. - slice assignment will no longer modify the data if the assignment operation fails - fixed error in matrix * scalar multiplication - euler.toMatrix(), toQuat() no longer causes "creep" from repeated use - Wrapped data will generate wrapped objects when toEuler(), toQuat(), toMatrix() is used - Quats can be created with angle/axis, axis/angle - 4x4 matrices can be multiplied by 3D vectors (by popular demand :)) - vec *quat / quat * vec is now defined - vec.magnitude alias for vec.length - all self, internal methods return a pointer to self now so you can do print vector.internalmethod() or vector.internalmethod().nextmethod() (no more print matrix.inverse() returning 'none') - these methods have been deprecated (still functioning but suggested to use the corrected functionality): * CopyVec() - replaced by Vector() functionality * CopyMat() - replaced by Matrix() functionality * CopyQuat() - replace by Quaternion() functionality * CopyEuler() - replaced by Euler() functionality * RotateEuler() - replaced by Euler.rotate() funtionality * MatMultVec() - replaced by matrix * vector * VecMultMat() - replaced by vector * matrix - New struct containers references to python object data or internally allocated blender data for wrapping * Explaination here: math structs now function as a 'simple wrapper' or a 'py_object' - data that is created on the fly will now be a 'py_object' with its memory managed by python * otherwise if the data is returned by blender's G.main then the math object is a 'simple wrapper' and data can be accessed directly from the struct just like other python objects.
