Gouraud shading is the simplest rendering method and is computed faster than Phong shading. It does not produce shadows or reflections. The surface normals at the triangle's points are used to ...

Phong shading is more realistic than Gouraud shading, but requires more computation. It does not produce shadows or reflections. The surface normals at the triangle's points are used to compute a ...

Common practical techniques that use apparatus include filtration, evaporation and distillation, Drawn in pencil. Lines should be firm and continuous with no gaps or shading - not sketchy like in art.

On top of this, the Pencil has pressure sensitivity built-in and it can detect the angle you’re holding it, so apps can switch from pencil or brush rendering to, say, lighter strokes, subtle shading 2 ...

and both tilt and pressure sensitivity make using the Pencil easier. Thanks to this feature, you can draw lines of varying weights and get a better result when shading, making it an attractive ...
