Calculating normals in a triangle mesh

http://stackoverflow.com/questions/6656358/calculating-normals-in-a-triangle-mesh

how to calculate the normals for this. Does each vertex have its own normals or does each triangle have its own normals.. geometry normals share improve this question Does each vertex have its own normals or does each triangle have its own normals.. in N dimensions you need a plane to calculate a normal. A vertex position is just a point and thus singular so you actually need..
