It is the answer, "What color is this point." This is the light of how much, in total, multiply it in a light gray that has been falling on it, you need to know "this point is what color" answer to the question of It means that for the light of how much you have to find even with the default material has been reflected from each light in a scene from the perspective of the right, specular its color (the default is white) by, over this, add this to the previous results. Unless you have changed the preferences of Cheetah 3D, and it is light gray, there is a specular highlights. The default material (those not given the material substances have) is a little more complex.
When you request a color renderer is what the ones that have this material, the answer is always the same. Simple substance is composed of a single node is simply Cheetah 3D - Solid shader node. That triangle, which has a material, the material on the concrete point of the triangle line renderer has been struck, you must say what is the color. Renderers Cheetah 3D, (ie being rendered, sub-pixel or a pixel) view port that through, to send a virtual ray from the view point, to render the image, the scene it (in fact something, until it touches the triangles). In addition, the same way recursively (in and on and follow the limitation that you set in the configuration of the renderer) may generate a new line there is a need to resolve. Material, along with information about, you do this by obtaining the information light beam is projected onto a surface, to supply it to the shader (mainly lighting information) scene.
Material, a specific point on a given object is a system for determining what colors.
