Subject: Proto Interface

Sender: Bryancreer@aol.com 17.11.06 15:40

I have been having trouble with PROTOs. For instance, the following PROTO -

#VRML V2.0 utf8

PROTO Ball [
    exposedField    SFColor        diffuseColor    1.0 1.0 1.0
    exposedField    SFVec3f        translation    0.0 0.0 0.0
    exposedField    SFFloat        radius        1.0
]{
    Transform {
        translation IS translation
        children [
            Shape {
                appearance Appearance {
                material Material {
                diffuseColor IS diffuseColor
                }
                }
                geometry Sphere {radius IS radius}
            }
        ]
    }
}

called from the following World -

#VRML V2.0 utf8

WorldInfo {
title "Ball Proto Test"
}
NavigationInfo {
type [ "WALK", "ANY" ]
headlight FALSE
avatarSize [ 0.25 1.6 0.5 ]
}

DirectionalLight {
    ambientIntensity 0.5
    direction -0.5 -0.5 -1
}

DirectionalLight {
    ambientIntensity 0
    intensity 0.25
    direction 0 0 1
}

DEF Front Viewpoint {
position 0 1.6 15
orientation 0 0 1 0
fieldOfView 0.785398
description "Front"
}

EXTERNPROTO Ball [
    exposedField    SFColor        diffuseColor
    exposedField    SFVec3f        translation
    exposedField    SFFloat        radius
] "Protos/Ball.wrl"

Transform {
    children [
        DEF Ball_1 Ball {
            diffuseColor 1.0 0.0 0.0
            translation 3.0 4.0 0.0
            radius 3.0
        }
    ]
}

doesn't display the Sphere. If I make 'radius' a field instead of an exposedField, it works and diffuseColor and translation work properly. It works as expected in BS Contact and Blaxxun Contact.

Any suggestions? Is this a bug in Cortona?
