It just runs two functions you supply — a vertex shader and a fragment shader — and expects you to write creative functions to get the results you want. In other words, if you want lighting you have to calculate it yourself. how much marzipan for 10 inch square cake

What he did was place L at infinity and make the surface a perfect reflector (that always reflected the maximum specular light) towards the view (where ever it was).

WebThe program is essentially a sophisticated viewer for geometric data. Users can interactively control the appearance of objects, by changing the lighting, shading and material properties of the surface. Phong shading leads to realistic-looking objects. Moreover, three- and four-dimensional objects can be viewed with perspective, orthogonal ... WebThe Phong Shading Model is commonly used to create specular effects. It is based on the assumption that the way a surface reflects light is a combination of the diffuse reflection of rough surfaces with the specular reflection of shiny surfaces.
