Nodes are the essential building blocks in the Advanced interface to the Poser Material Room. They are the graphical representation of mathematical function calls, that is: calculation procedures which turn parameters (inputs) to a result (output).<\/p>\n

The Diffuse component <\/a>in the PoserSurface material definition\u00a0acts as a neutral entry into the spine with the diffuse node already attached to it<\/em><\/strong>. It embeds the material definition as represented by the diffuse node right into the PoserSurface.<\/p>\n

\"\" is equivalent to \"\"<\/p>\n

The separate diffuse node itself enables me to apply this definition explicitly in other occasions, like an element in a shading tree plugged into the Alternate Diffuse entry. So, when I disable (blacken out) the Diffuse component and plug the diffuse node into Alternate Diffuse <\/a>(which is a neutral node by itself), I\u2019ll get the same result.<\/p>\n

The Diffuse node (as well as its embedded variant) responds to all sorts of diffuse light. When IDL lighting is enabled, this not only includes diffuse light from direct (point- spot- infinite) sources but also includes the ambient, reflected, diffused and specular-turned-into-highlight from surrounding objects in the scene. The response is to re-emit the received light, independent of any angle of incidence for the incoming light rays, according to Lamberts formula<\/a>. Plus: Color and Value work together<\/a>. This Lambert representation of material is fast to calculate, but falls short for a neat illusion of especially porous stuff like cloth, wood, plants, skin, brick, etc. Those materials might be better off with the Clay node<\/a>. Additional alternatives are offered by the various Scatter nodes<\/a>.<\/p>\n

\nLeft: Diffuse Color, Value (set to 1.0) and Normals Forward embedded in the PoserSurface definition. Right: the embedded diffuse is nullified (Value=0), the node is plugged into Alt Diffuse. Like in the PoserSurface itself, the Diffuse node has Color, Value and Normals Forward for parameters.<\/p>\n
