create and rendering another world w/framework

[Rick]

So I'm trying to create another world along side framework and I'm wondering if I'm doing some things correctly in the C# library. I'm also using Klepto's control.

 

Inside the controls init event I create my world, and it's camera, set that to the current world, then load a mesh. Then set it back to the main layers world.

topWorld = new World();
           Leadwerks.World.Current = topWorld;
           topCamera = new Camera();

           // load model
           xAxis = Mesh.Load("abstract::x_red.gmf");
           xAxis.Position = new Vector3(0, 0, 0);

           Leadwerks.World.Current = Leadwerks.Framework.Layers.Main.World;

 

In AfterRender I switch the current world to the top world, set that camera's matrix to the main layers camera matrix, clear the depth buffer to what I assume would be the currently selected buffer, render the world, then set the current world back.

 

 

All this results in nothing being displayed on the screen. What am I missing? If I take all the extra world stuff out and just load the mesh in the main layers world I see the mesh.

You don't need another world, just put the 3D GUI objects near to the camera.

This isn't just for 3D, it's also for moving axis controls on selected models in an editor. I'm using 3D models for these axis controls and they need to be drawn on top always. Either way, I'm looking for this effect.

 

Also putting them in a non always on top world could lead to issues. I have to worry about models coming between the planes and my camera, I have to worry about lighting in whatever world they exist in, and I wouldn't want post processing effects to be on the GUI controls.

Wait until right before your flip commands, set the world, render it, set back.

When I did this in C w/o the framework it seemed I had to also do CameraClearMode(topCamera, BUFFER_DEPTH); with my topCamera and then it worked. Now I have to test with a normal C# program to see if that works, and if that works I then need to figure out how to get it to work with kelpto's control because currently it's not working.
