public abstract class GRShadedShape extends GRActor3D
The parameter diffuseColor determines the color of the object in the usual sense that it determines the color of light reflected off the object. The default is gray. The parameter emissiveColor specifies a color that is emitted by the object, and hence does not depend on illumination. It is black by default, which means that the object does not emit any light and will be invisible without illumination. The parameter specularColor determines the color of highlights that are reflected by the object if the object is set to be shiny.
The parameter shininess determines the shininess of the object. It ranges from 1.0 (the default) to 128.0, meaning not shiny to very shiny. A shiny object reflects the specularColor, unless it is black, in which case shininess has no effect.
The texture parameter can be used to specify an image file. The specified image will be mapped onto the shape.
The parameter transparency determines the transparency of the object. It ranges from 0.0 (the default) to 1.0, meaning opaque to fully transparent (which makes the object invisible).
The wireFrame parameter can be used to view only the lines that outline the polygons of the object and not the surface. The flat parameter can be set to make rendered polygons flat rather than rounded at the corners.
The allowRuntimeChanges parameter, if true, specifies that changes to parameter values during the execution of the model take effect immediately. By default, this parameter is false, which means that changes to parameter values take effect only on the next run of the model. A value of false yields better performance, but less interactivity. Changing this to true will only have an effect on the next run of the model.
