Linear interpolation - Wikipedia
Given the two red points, the blue line is the linear interpolant between the points, and the value y at x may be found by linear interpolation. In mathematics, linear interpolation is a method of curve fitting using linear polynomials to construct new data points within the range of a discrete set of known data points. In this geometric visualisation, the value at the green circle multiplied by t
Computing Tangent Space Basis Vectors for an Arbitrary Mesh - Eric Lengyel
Eric Lengyel • March 15, 2004 Modern bump mapping (also known as normal mapping) requires that tangent plane basis vectors be calculated for each vertex in a mesh. This article presents the theory behind the computation of per-vertex tangent spaces for an arbitrary triangle mesh and provides source code that implements the proper mathematics. [Edit: this derivation first appeared in Mathematic
