Computing a point of reflection on a sphere
WebSphere map texture generation has been supported by OpenGL since version 1.0. While the other two texture generation modes create three texture coordinates, sphere map generation only produces two; s and t.It does this by generating a reflection vector, as defined previously, then scaling the R x and R y components by a modified reflection … WebBloch sphere. In quantum mechanics and computing, the Bloch sphere is a geometrical representation of the pure state space of a two-level quantum mechanical system ( qubit …

WebAedenvelvet. 7 months ago. The centre of the reflecting surface of a mirror is called the Pole(P). It lies ON the mirror. This is different from the Centre of curvature(R). Each spherical mirror forms a part of an imaginary circle. The centre of this circle is called Centre of curvature. It DOES NOT lie on the mirror.
