VRML2.0 "ambientIntensity" is calculated by the mean factor between the Inventor "ambientColor" and "diffuseColor".

How to use these materials :

VRML 2.0 supports Prototypes definitions as well as External Prototypes, the easiest way to use these materials is to gather the materials inside a separate file and declare an EXTERNPROTO in the file you want to use these materials (see example below).

Unfortunately, most of the VRML 2.0 browsers doesn't seem to support external prototypes (especially PC versions), so you might as well cut an paste any material prototype inside the file you want to use it.

External prototype usage :

file : Materials.wrl
`#VRML V2.0 utf8 PROTO MyMaterial00 [] { Material { ambientIntensity 0.263158 diffuseColor 0.345455 0.163262 0.122622 specularColor 0.212121 0.107475 0.000000 emissiveColor 0.021212 0.010747 0.000000 shininess 0.048649 transparency 0.100000 } } . . . PROTO MyMaterial27 [] { Material { ambientIntensity 0.240506 diffuseColor 0.277281 0.104336 0.079900 specularColor 0.305587 0.141916 0.2705727 emissiveColor 0.030559 0.014192 0.0270573 shininess 0.096970 transparency 0.000000 } }`	Materials prototype definition with `PROTO`. Note that these `PROTO` have no field nor events to rule their behaviour as they are only "definitions".
file : Material_example.wrl
`#VRML V2.0 utf8 EXTERNPROTO MyMaterial07 [] "http://.../Materials.wrl#MyMaterial07" EXTERNPROTO MyMaterial15 [] "http://.../Materials.wrl#MyMaterial15" . . . Group { children [ DEF Right_Object Transform { translation 2 0 0 children [ Shape { appearance Appearance { material MyMaterial07 {} } geometry Sphere {} } ] }, DEF Left_Object Transform { translation -2 0 0 children [ Shape { appearance Appearance { material MyMaterial15 {} } geometry Cylinder {} } ] } ] }`	All the `PROTO` to be used should be instancied using an `EXTERNPROTO` statement refering to the Material definition file with an `URL` field.
