This is the second demo I ported tonight. Its the Transparency demo... I have been picking random demos to port.

TransparencyApp.cs:

using System;

using System.Collections.Generic;

using System.Text;

using Mogre;



namespace Transparency

{

    class TransparencyApp : Mogre.Demo.ExampleApplication.Example

    {

        public override void CreateScene()

        {    

            // Just override the mandatory create scene method

            // Set ambient light

            sceneMgr.AmbientLight = new ColourValue(0.5f, 0.5f, 0.5f);



            // Create a light

            Light l = sceneMgr.CreateLight("MainLight");

            // Accept default settings: point light, white diffuse, just set position

            // NB I could attach the light to a SceneNode if I wanted it to move automatically with

            //  other objects, but I don't

            l.Position = new Vector3(20,80,50);



            // Create a prefab plane

            Entity planeEnt = sceneMgr.CreateEntity("Plane", SceneManager.PrefabType.PT_PLANE);

            // Give the plane a texture

            planeEnt.SetMaterialName("Examples/BumpyMetal");



            // Create an entity from a model (will be loaded automatically)

            Entity knotEnt = sceneMgr.CreateEntity("Knot", "knot.mesh");



            knotEnt.SetMaterialName("Examples/TransparentTest");



            // Attach the 2 new entities to the root of the scene

            sceneMgr.RootSceneNode.AttachObject(planeEnt);

            sceneMgr.RootSceneNode.AttachObject(knotEnt);



            // Add a whole bunch of extra transparent entities

            Entity cloneEnt;

            for (int n = 0; n < 10; ++n)

            {

                // Create a new node under the root

                SceneNode node = sceneMgr.CreateSceneNode();

                // Random translate

                Vector3 nodePos;

                nodePos.x = Mogre.Math.SymmetricRandom() * 500.0f;

                nodePos.y = Mogre.Math.SymmetricRandom() * 500.0f;

                nodePos.z = Mogre.Math.SymmetricRandom() * 500.0f;

                node.Position = nodePos;

                sceneMgr.RootSceneNode.AddChild(node);

                // Clone knot

                cloneEnt = knotEnt.Clone("Knot" + n.ToString());

                // Attach to new node

                node.AttachObject(cloneEnt);



            }

        }

    }

}

Program.cs:

using System;

using System.Collections.Generic;

using System.Text;



namespace Transparency

{

    class Program

    {

        static void Main(string[] args)

        {

            try

            {

                TransparencyApp app = new TransparencyApp();

                app.Go();

            }

            catch

            {

                // Check if it's an Ogre Exception

                if (Mogre.OgreException.IsThrown)

                    Mogre.Demo.ExampleApplication.Example.ShowOgreException();

                else

                    throw;

            }

        }

    }

}
