Create and add a simple colored material. This method takes diffuse color and let you control several other aspects of the material. Ambient color will be assumed to a be a dimmer shade of the supplied diffuse color (diffuse / 4).<p>

    <tr><td valign="top"></td><td valign="top"><em>bAdditive</em>&nbsp;</td><td>true for an additive material (default is false). This means that the rendered color will be added to, rather than replace, the rendering surface. This is useful for some effects such as drawing stars against a twilight sky, in which the light of a dim star should be added to the background sky.</td></tr>
    <tr><td valign="top"></td><td valign="top"><em>fAmbient</em>&nbsp;</td><td>Ambient material value, ranges from 0 to 1 (default 0). If lighting is enabled, this determines how this material is affected by the Ambient component of each existing light.</td></tr>
    <tr><td valign="top"></td><td valign="top"><em>fDiffuse</em>&nbsp;</td><td>Diffuse material value, ranges from 0 to 1 (default 1). If lighting is enabled, this determines how this material is affected by the Diffuse component of each existing light. If lighting is not enabled, this indicates the exact lighting value to use for the material.</td></tr>
    <tr><td valign="top"></td><td valign="top"><em>fAlpha</em>&nbsp;</td><td>Alpha value (opacity), ranges from 0 (completely transparent) to 1 (opaque). Default is 1. If transparency is not enabled, this value is ignored.</td></tr>

This is useful for geometry which is brighter than the existing light level, such as illuminated objects at night.</td></tr>
    <tr><td valign="top"></td><td valign="top"><em>bTexGen</em>&nbsp;</td><td>true for materials whose texture mapping will be generated automatically. false if you will provide explicit UV values to drape your texture. Default is false.</td></tr>
    <tr><td valign="top"></td><td valign="top"><em>bClamp</em>&nbsp;</td><td>true for Texture Clamping, which prevents sub-texel interpolation at the edge of the texture. Default is false.</td></tr>
    <tr><td valign="top"></td><td valign="top"><em>bMipMap</em>&nbsp;</td><td>true for Mip-mapping, which provided smoother interpolation of the textured geometry when it is under-sampled (generally when it is in the distance.) Useful for avoiding unpleasant aliasing artifacts, but costs 1/3 more texture memory.</td></tr>
