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
Most likely will not compile for others, I'd appreciate any build errors
and missing files reports (I can never seem to get everything committed
and all the build systems working without help).
Porting over the sculpt/multires tools was a breeze,
thanks goes to brecht for a design that didn't exclude
ngons and was easy to port.
Note that I've not tested externally-backed multires
file support yet. Also, I still need to write version
patch code for some cases.
Some notes:
* Like trunk, topological changes don't update multires right,
so e.g. subdivide will duplicate multires data on the new faces,
instead of subdividing it.
* If you set the debug value (ctrl-alt-d) to 1 it'll turn on
my experiments in speeding up sculpting on higher-res multires
meshes (but note it makes partial redraw not completely accurate).
* There's a bug where you have to go through editmode to get out
of sculpt mode, not sure if I inherited or created this myself.
* 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
####
