Getting started with shading

    The basic info on shading is covered in Maya:Tutorials:Rendering.

Throughout the shading sections, the book instructs you to open the
Multi-Lister and choose Shaders from a menu. In the version of Alias
that we have, choose Windows->Multi-lister->Shaders....  Shading
models

    Each shading model is named after the graphics person who developed it. Don't worry about the details of these models. They basically work well for different types of materials:

        * Lambert -- matte and unpolished surfaces
        * Phong -- glass and glossy surfaces
        * Blinn -- reflective metals
        * Lightsource -- don't use this 

    The shading parameters vary according to the model chosen. Focus on tweaking the following parameters:

        * Lambert
              o Diffuse -- how much light is reflected from surface
              o Color -- as you know it
              o Incandescence -- color of unlit parts of surface (corresponds to ambient color) 
        * <a href="phong.html">Phong</a>
              o Diffuse
              o Color
              o Incandescence
              o Specular -- color and intensity of specular highlight (intensity is implicitly controlled by color value)
              o Shininess -- size of specular highlight
              o Reflectivity -- degree to which surroundings are reflected
              o Transparency -- color and amount of transparency (as with Specular, amount of transparency is implicitly controlled by color) 
        * Blinn
              o Diffuse
              o Color
              o Incandescence
              o Specular
              o Reflectivity
              o Specular Rolloff -- parameter which controls the effect of increasing reflectivity at oblique angles
              o Eccentricity -- size of specular highlight (unlike Shininess only in that slider works in opposite direction) 

    Texture mapping

    Alias provides three texture mapping tools:

        * parametric mapping -- texture mapping as you know it
        * solid projections -- various ways to cheat at achieving a solid texture effect
        * real solid texture mapping, in which a model is "carved out" of a solid block of texture 

    Rendering

    Read lesson 12 in Learning Alias to get the basics of
    rendering. If your scene has reflective or transparent objects in
    it, be sure to use Raytracing instead of Raycasting. Choose
    Raytracing or Raycasting using the option dialog for
    Render->Render.

    The rendered images go into the pix directory of the current
    project. You can view an image that is rendering or was just
    rendered using Render->Show render.
