Module nalgebra::geometry

[Reexported at the root of this crate.] Data structures for points and usual transformations (rotations, isometries, etc.)

Structs

Isometry	A direct isometry, i.e., a rotation followed by a translation, aka. a rigid-body motion, aka. an element of a Special Euclidean (SE) group.
Orthographic3	A 3D orthographic projection stored as a homogeneous 4x4 matrix.
Perspective3	A 3D perspective projection stored as a homogeneous 4x4 matrix.
Point	A point in a n-dimensional euclidean space.
Quaternion	A quaternion. See the type alias UnitQuaternion = Unit<Quaternion> for a quaternion that may be used as a rotation.
Reflection	A reflection wrt. a plane.
Rotation	A rotation matrix.
Similarity	A similarity, i.e., an uniform scaling, followed by a rotation, followed by a translation.
Transform	A transformation matrix in homogeneous coordinates.
Translation	A translation.

Enums

TAffine	Tag representing an affine Transform. Its bottom-row is equal to (0, 0 ... 0, 1).
TGeneral	Tag representing the most general (not necessarily inversible) Transform type.
TProjective	Tag representing the most general inversible Transform type.

Traits

AbstractRotation	Trait implemented by rotations that can be used inside of an Isometry or Similarity.
SubTCategoryOf	Indicates that Self is a more specific Transform category than Other.
SuperTCategoryOf	Indicates that Self is a more general Transform category than Other.
TCategory	Trait implemented by phantom types identifying the projective transformation type.
TCategoryMul	Traits that gives the Transform category that is compatible with the result of the multiplication of transformations with categories Self and Other.
