obliqueobject
Obliqueobject is a term used in discussions of oblique geometry and projection to describe a geometric object whose natural description relies on an oblique coordinate frame rather than a standard orthonormal one. The defining feature is that the basis vectors are non-orthogonal, which means coordinates do not directly correspond to orthogonal distances in space.
Mathematically, an oblique object in R^3 can be described with a basis b1, b2, b3 that are
Oblique projection, a central operation for oblique objects, maps a 3D point to a 2D plane by
Common special cases in practice are cavalier and cabinet projections, which are two well-known oblique projections
Applications include technical illustration, education in linear algebra and geometry, and rapid drafting. Underlying theory overlaps
Historically, oblique projections emerged in engineering drawing as a practical alternative to perspective, and the obliqueobject
