This mesh looks like it would be difficult to deform (i.e. for animation) since it would not bend at all in the middle.
It was said in class that we want more "round triangles" partially because interpolation is hard. In this case, the figure is all blue, so color interpolation isn't an issue; however, does the mesh make it harder to render the light reflection?
@anonymous Perhaps. In order to shade the triangle, we typically first compute a normal at every point on the triangle by interpolating from the normals at its vertices. If the mesh geometry is chosen poorly, the result of this interpolation can potentially mess up the shading.
