Currently the most used scene graph transformation implementation are
dual quaternions, which don't allow any scaling. The original code
normalized the rotation matrix, involving three dot products and one
sqrt, even if it wasn't needed in most cases -- even if using scene
graph with matrices mostly you don't scale at all and thus the shader
internally renormalized already normalized vectors for _each object_ in
each frame.
This _will_ break things, don't forget to update the code and call
`setNormalMatrix()` along with `setTransformationMatrix()`.
Use AbstractCamera<dimensions, T>, Drawable<dimensions, T> and
DrawableGroup<dimensions, T> like before and add two kinds of aliases
instead of only one: AbstractBasicCamera2D<T>/AbstractBasicCamera3D<T>,
BasicDrawable2D<T>/BasicDrawable3D<T> and
BasicDrawableGroup2D<T>/BasicDrawableGroup3D<T> for abstract type and
AbstractCamera2D/AbstractCamera3D, Drawable2D/Drawable3D and
DrawableGroup2D/DrawableGroup3D for Float.
Also fixed some find&replace errors in documentation and include guards.
Partially reverts commit a0d60bbaa7.
Use AbstractTransformation<dimensions, T> like before and add two
kinds of aliases instead of only one:
AbstractBasicTransformation2D<T>/AbstractBasicTransformation3D<T> for
abstract type and AbstractTransformation2D/AbstractTransformation3D for
Float.
Partially reverts commit 346ea2feb6.
Use AbstractFeature<dimensions, T>, AbstractGroupedFeature<...>,
AbstractFeatureGroup<...>, FeatureGroup<...> like before and add two
kinds of aliases instead of only one, one with *Basic* for abstract type
and one for Float type.
Partially reverts commit 572efce3f7.
Use Animable<dimensions, T> and AnimableGroup<dimensions, T> like before
and add two kinds of aliases instead of only one:
BasicAnimable[Group]2D<T>/BasicAnimable[Group]3D<T> for abstract type
and Animable[Group]2D/Animable[Group]3D for Float.
Partially reverts commit c32c12b387.
Use AbstractObject<dimensions, T> like before and add two kinds of
aliases instead of only one:
AbstractBasicObject2D<T>/AbstractBasicObject3D<T> for abstract type and
AbstractObject2D/AbstractObject2D for Float.
Makes it easier to use AbstractObject in templates of fixed dimensions
(e.g. Bullet integration, where it can now be written as
`AbstractBasicObject2D<btScalar>` instead of potentially confusing
`AbstractBasicObject<2, btScalar>`).
Partially reverts commit cfd405c32c.
