Examples.
euler = Euler(1, 2, 3)
euler.order = 'ZXY'
euler = matrix.to_euler('XZY')
Still missing rna support. this still wont give the right order, defaulting to XYZ.
eul = object.rotation_euler
- disallow setting swizzle's that have duplicate values: vec.xxx = [1,2,3]
- raise an error if the list setting a swizzle's longer.
- mathutils write callback was running on the wrong vector, which could crash blender.
- bpy.app moved into PyStructSequence (used by sys.float_info)
- added buildinfo into bpy.app.build_*
- bpy.ui removed (wasnt used)
- include external example files in Mathutils docs (only Mathutils and Vector are currently written)
- added support to auto document PyStructSequence's
- CMake had "'s inside all its strings.
* inline some more functions, from math_base and math_vector
* also made some changes to the way inline is done so it can
work for more than one file
* reflect_v3_v3v3 requires input vectors to be normalized now.
* added rgb_to_grayscale
* added zero_v4, copy_v4_v4, swap_v4_v4, is_one_v3
* added box_clip_bounds_m4 to clip a bounding box against a
projection matrix
* utility function BLI_findstring to avoid listbase lookup loops everywhere.
eg:
ListBase *lb= objects= &CTX_data_main(C)->object;
Object *ob= BLI_findstring(lb, name, offsetof(ID, name) + 2);
* made some more math functions use const's, (fix warnings I made in previous commits)
From 2 triangles and 1 point, the relative position between the point and the first triangle is applied to the second triangle to find the target point.
the barycentric weights are calculated in 2D space with a signed area so values outside the triangle bounds are supported.
wrapped by python:
pt_to = Geometry.BarycentricTransform(pt_from, t1a, t1b, t1c, t2a, t1b, t1c)
NOTE:
- moved some barycentric weight functions out of projection painting into the math lib.
- ended up making some of the math functions use const args.
TODO:
- support exceptional cases. zero area tries and similar.
From the tracker:
- typo was making the multiplication to transpose resulting matrix
eg
####
from Mathutils import *
from math import radians
cont = GameLogic.getCurrentController()
owner = cont.owner
owner.worldOrientation = RotationMatrix(radians(1), 3, 'z') * owner.worldOrientation
####
- the scripts path set in the user preferences or ~/.blender/scripts/ui (io, op, io etc..) will be used to load scripts.
- the default home dir part probably only works in *nix os's
- Added a missing sync callback to vector.toTuple()
* Convert all code to use new functions.
* Branch maintainers may want to skip this commit, and run this
conversion script instead, if they use a lot of math functions
in new code:
http://www.pasteall.org/9052/python
- terrible typo was making the multiplication to run in an infinite loop.
- Any matrix * vector multiplication would crash Blender.
eg
####
import Mathutils
from Mathutils import *
vec_ray = Vector(0.0, 0.0, 1.0)
tilt_mat = RotationMatrix(0.0, 3, "y")
vec_ray = tilt_mat * vec_ray
####
strangely vector.c was skipped in last merge from trunk.
-----------------------------------
Mathutils fix: Vector.reflect
* correct function for reflection and moving it to arithb.c
