d93ba137f2 Introduce EIGEN_PI, get rid of M_PI and acos(-1.0) 2015-06-10 17:12:10 +02:00
Christoph Hertzberg
324e7e8fc9 Removed the deprecated EIGEN2_SUPPORT, as previously announced. A compilation error is raised, if this compile-switch is defined. The documentation references to the corresponding pages from Eigen3.2 now. Also, the Eigen2 testsuite has been removed. 2014-07-01 16:58:11 +02:00

64a85800bd Added support for AVX to Eigen. 2014-01-29 11:43:05 -08:00

e5de9e5226 Remove \nonstable yet. The stability rules for Eigen3 are much simpler: 
- all what's not in unsupported/ is considered stable API
    (except internal stuff e.g. expression templates).

e4f64ce098 add optimized quaternion * quaternion product specialization for 
float/SSE using code from Rohit Garg

0be89a4796 big addons: 
* add Homogeneous expression for vector and set of vectors (aka matrix)
  => the next step will be to overload operator*
* add homogeneous normalization (again for vector and set of vectors)
* add a Replicate expression (with uni-directional replication
  facilities)
=> for all of them I'll add examples once we agree on the API
* fix gcc-4.4 warnings
* rename reverse.cpp array_reverse.cpp
 2009-03-05 10:25:22 +00:00

a79deafc6d * mark Geometry as experimental 
* install QtAlignedMalloc
* finish the renaming Regression->LeastSquares
* install LeastSquares directory (!!!)
* misc dox fixes

8106d35408 Patch by Kenneth Riddile: disable MSVC warnings, reenable them outside 
of Eigen, and add a MSVC-friendly path in StaticAssert.

faf942a947 Add a generic matrix to Euler-angles function. 
Perhaps the prototype of this function could be improved,
see comments in the code

ca048aaf77 fix compilation with gcc 4.3 2008-10-26 20:43:05 +00:00

94f6f2a7de Add an axis aligned box in the geometry module. 
Some naming questions:
- for "extend" we could also think of: "expand", "union", "add"
- same for "clamp": "crop", "intersect"
- same for "contains": "isInside", "intersect"
=> ah "intersect" is conflicting, so that eliminates this one !

52406aecad * Extend a bit ParametrizedLine and move it to a separate file, 
add unit-tests for it.
* remove "using namespace std" in test/main.h such that the compilation
  bug found today in SVD won't happen again.

9c450a52a2 Split Rotation.h to Rotation2D.h and RotationBase.h, 
and more code factorization based on RotationBase.
Added notes about the main aim of the Translation and Scaling classes.
 2008-08-30 21:36:04 +00:00
Gael Guennebaud
6ba991aa3a * added a RotationBase class following the CRT pattern 
This allow code factorization and generic template specialization
  of functions
* added any_rotation * {Translation,Scaling,Transform} products methods
* rewrite of the actually broken ToRoationMatrix helper class to
  a global ei_toRotationMatrix function.

236b7a545d update Transform::inverse() to take an optional argument stating whether the transformation is: 
NonAffine, Affine (default), contains NoShear, contains NoScaling
that allows significant speed improvements. If you like it, this concept could be applied to
Transform::extractRotation (or to a more advanced decomposition function) and to Hyperplane::transformed()
and maybe to some other places... e.g., I think a Transform::normalMatrix() function would not harm and
warn user that the transformation of normals is not that trivial (I saw this mistake much too often)

9e7a9cde14 Add Scaling and Translation class as discussed on ML, still missing: 
* handling Quaternion, AngleAxis and Rotation2D, 2 options here:
 1- make all of them inheriting a common base class Rotation such that we can
    have a single version of operator* for all the rotation type (they all get converted to a matrix)
 2- write a version for all type (so 3 rotations types * 3 for Transform,Translation and Scaling)
* real documentation

6d841512c7 some hyperplane changes: 
- the coefficients are stored in a single vector
- added transformation methods
- removed Line* typedef since in 2D this is really an hyperplane
  and not really a line...
- HyperPlane => Hyperplane
 2008-08-29 13:30:37 +00:00

9b4d46c82e * Add an HyperPlane class in the Geometry module 
with its respective unit-test.
  Feel free to discuss the API on the ML.
* Some bugfix in unitOrthogonal found by the hyperplane unit test.

63d3ef8204 * remove debug code commited by mistake in Assign 
* keep going on the doc: added a short geometry tutorial
 2008-08-26 23:07:33 +00:00

00a8d314c5 * move memory related stuff to util/Memory.h 
* clean ugly doxygen inheritence of expressions
* keep improving the documentation... slowly !

a6d387a359 Various compilation fixes for MSVC 9. All tests compile but some 
still fail at runtime in ei_aligned_free() (even without vectorization).

13ad88736e last small fixes, this is alpha6, eigen2 is now ready for eigen1 apps to 
port to.

172000aaeb Add .perpendicular() function in Geometry module (adapted from Eigen1) 
Documentation:
 * add an overview for each module.

6e2c53e056 Added an automatically generated list of selected examples in the documentation. 
Added the custom gemetry_module tag, and use it.

05ad083467 Added MatrixBase::Unit*() static function to easily create unit/basis vectors. 
Removed EulerAngles, addes typdefs for Quaternion and AngleAxis,
and added automatic conversions from Quaternion/AngleAxis to Matrix3 such that:
 Matrix3f m = AngleAxisf(0.2,Vector3f::UnitX) * AngleAxisf(0.2,Vector3f::UnitY);
just works.

bc0c7c57ed Added an extensible mechanism to support any kind of rotation 
representation in Transform via the template static class
ToRotationMatrix.
Added a lightweight AngleAxis class (similar to Rotation2D).
