WebIn vector calculus, divergence is a vector operator that operates on a vector field, producing a scalar field giving the quantity of the vector field's source at each point. More technically, the divergence represents the volume density of the outward flux of a vector field from an infinitesimal volume around a given point..

So to answer your question, you find the gradient of a tensor field by viewing the directional derivative as a linear function of the direction. When you have a basis, as you do for R n, this linear function can be represented ...

A positive value is assigned if the point is in the outer region of the nearest surface and negative if it is inside. In this way, it produces a compact representation of the geometry information of a scene. grade 11 results 2022 namibia newspaper
