ITransformable Interface

###ITransformable (In Development)

To use this API one must currently use reflection to determine if the render package implements this interface or not, failure to do so will break your nodes on Dynamo 1.0.!! We are investigating alternatives and will update this space and the API changes doc with updates.

https://github.com/DynamoDS/Dynamo/blob/master/src/NodeServices/GraphicsDataInterfaces.cs#L217

a sample usage from a zero touch node looks like:

namespace ItranfromableThing
{
    public class TransformableThing : IGraphicItem
    {
        public Geometry geo { get; private set; }
        public CoordinateSystem transform { get; private set; }

        public static TransformableThing byThingGeoCS(Geometry geo, CoordinateSystem cs)
        {
            var tt = new TransformableThing();
            tt.geo = geo;
            tt.transform = cs;
            return tt;
        }


        public void Tessellate(IRenderPackage package, TessellationParameters parameters)
        {
            geo.Tessellate(package, parameters);
//look for the method SetTransform with the double[] argument list.
            var method = package.GetType().
            GetMethod("SetTransform", System.Reflection.BindingFlags.Public |
 System.Reflection.BindingFlags.Instance,
 null, 
new[]{ typeof(double[]) }, null);

//if the method exists call it using our transform.
if (method != null)
            {
method.Invoke(package, new object[] { new double[]
{transform.Xaxis.x,transform.Xaxis.y,transform.Xaxis.Z,0
transform.Yaxis.x,transform.Yaxis.y,transform.Yaxis.z,0
transform.Zaxis.x,transform.Zaxis.y,transform.Zaxis.z,0
transform.origin.x,transform.orign.y,transform.origin.z,1
}});
            }
               
        }

    }

}
