WebA polygon and its two normal vectors. A normal to a surface at a point is the same as a normal to the tangent plane to the surface at the same point. In geometry, a normal is an object such as a line, ray, or vector that is perpendicular to a given object. For example, the normal line to a plane curve at a given point is the (infinite) line ... Web$\begingroup$ Refer to: "Weights for Computing Vertex Normals from Facet Normals". Generally you walk over all triangles that share a vertex and use all of the adjacent triangle normals to compute the normal at that vertex. To achieve this you can walk over all triangles and add their normals to their 3 adjacent vertices (with a weight).

Computing normals

In geometry, a normal is an object such as a line, ray, or vector that is perpendicular to a given object. For example, the normal line to a plane curve at a given point is the (infinite) line perpendicular to the tangent line to the curve at the point. A normal vector may have length one (a unit vector) or its length may represent the curvature of the object (a curvature vector); its algebraic sign may indicate s… WebIt uses a 2D texture (a lookup table) to record surface normals for a mesh. Each point on the surface of the mesh has a corresponding normal in the table. When computing the color for a fragment, we use the normal from the table instead of the interpolated vertex normal. As a result, we get a fake smooth surface with relatively low cost. License
