antlr3

Well how to evaluate a very simple antlr grammar that does only this.

Box(1,2,4) Cylinder(1,2) and builds java3d shapes,

(given I have already built a canvas for java3d and have the code for creating each element in java,

protected static BranchGroup addBox1(Float a, Float b, Float C){ // create branch for display TransformGroup bodyTransform = new TransformGroup(); BranchGroup bg = new BranchGroup(); bg.setCapability(BranchGroup.ALLOW_DETACH); bg.setUserData(shapeId); // set transformation bodyTransform = setTransformShape(0,0,0,0,0,0,0); // create box
Box tmpBox = new Box(a,b,c, Primitive.GENERATE_NORMALS | Primitive.GENERATE_TEXTURE_COORDS,setAppearance(color));
getCoords(tmpBox);

bodyTransform.addChild(tmpBox);
trFormList.add(bodyTransform);
shapeId++;
//add box to branch
bg.addChild(bodyTransform);
return bg;

} ) thanks
