This page summarizes API changes between Wm3 and Eigen, which yade will end up using soon.
To compile with deprecation warnings for Wm3 API, add the eigen-compat feature. Grep away warning comping from lib/miniWm3/* headers (comptibility functions call deprecated API functions and trigger those warning). You can capture build output to file:
scons > build.log 2>&1
and then grep only interesting warnings:
grep 'is deprecated' build.log | cut -f1,2 -d\' |grep -v miniWm3
Compilation in pure-eigen mode is not yet supported.
| Trivial changes | |
|---|---|
| ONE, ZERO, UNIT_X, UNIT_Y, UNIT_Z | Ones(), Zero(), UnitX(), UnitY(), UnitZ() [note call parentheses] |
| W(), X(), Y(), Z() | w(), x(), y(), z() |
| Dot, Cross, Transpose, Conjugate, Inverse, Determinant | dot, cross, transpose, conjugate, inverse, determinant |
| Non-trivial changes | |
| Quaternion::Align | Quaternion::setFromTwoVectors |
| Vector3::Normalize() | returns void, not norm anymore. Code adapted at affected places. |
| Quaternion::operator[] | Quaternion which stores elements in different order: x=[0], y=[1] (was: w=[0], x=[1], ..). Removed from code for clarity. |
| Matrix3::operator[] (i.e. matrix[0][2] access) | use matrix(0,2) instead |
| Length(), SquaredLength() | norm(), squaredNorm() |
| Quaternion::ToRotationMatrix, Quaternion::FromRotationMatrix | use constructors Quaternion(Matrix3) and Matrix3(Quaternion) directly |
| Quaternion::ToAxisAngle | us AxisAngle aa(axisAngleFromQuat(q)) which will be later trivially replaced by constructor in eigen, AxisAngle aa(q). |
| Quaternion::FromAxisAngle | Quaternion(AngleAxis) constructor |
| Matrix3::EigenDecomposition | (only once in clump code, handled by hand) |
| Matrix3::MakeTensorProduct | outer product; use makeTensorProduct(v1,v2) for compatibility now (vec1*vec2.transposed() in eigen) |
