Help with 2 problems: widows form and Camera

Hi guys

I started with OGRE last week and, with some difficulties, I am understanding how it work.

I´m making a small application using a windows form to test some features.
Everything works perfectly.

My next step was to create a plane. So, after building the application, it crashes when I finalize it. I don´t know why and only happens when i create a plane.

My other problem is that my PT_ORTHOGRAPHIC type Camera don´t "see" my plane when it has:
Camera.Position.x == plane.Position.x
Camera.Position.z == plane.Position.z

and

Camera.LookAt == plane.Position

I think it could be a rotation problem.

Any Idea to help me?

Thanks in advance.

well, off hand I'd try two things:
1st try changing the '==' to '='
== is the comparison operator for equality..

2nd, try moving the camera's initial position a little..

Camera.x = plane.Position.z + 100;


happy coding!

the LookAt function takes a vector3 as an argument...

So camera.LookAt(SomeVector3) rather than camera.LookAt = SomeVector3...

I think he's just telling you what the values equal with the "==".

@Al Capique
What is the plane's Normal? are you trying to look at it "Edge On"?
I've never used a orthographic camera, but you may not be able to see a plane "Edge on" with Ogre, you may need to fake it with a Line3D.

I think you would take the crossproduct of the plane
vecCross = crossproduct of plane.Pos and (plane.Pos + (plane.Normal * 2))
then draw a (plain.Pos + (vecCross *10)) to (plane.Pos +(vecCross *-10)

Sorry about the confusion in my post.

what I wanted to say was:

My other problem is that my PT_ORTHOGRAPHIC type Camera don´t "see" my plane when it has:
Camera.Position.x EQUAL plane.Position.x
Camera.Position.z EQUAL plane.Position.z

and

Camera.LookAt EQUAL plane.Position

@rastaman
No, i don´t trying to lok at it "Edge On"?

For exemple:
My plane is origin with normal (0,1,0)

My camera has position.y equal 2500
when the camera has position.x or position.z different of zero I can see the plane. But when it is on (0, 2500, 0) the plane disappears.

Here is my code.

If I uncomment the 6ª line (//this._Camera.SetPosition(0, 2500, 0)) I won´t see the plane anymore.

this._Camera = _SceneManager.CreateCamera("MainCamera");

this._Camera.NearClipDistance = 1000;

this._Camera.SetPosition(0.1f, 2500, 0);
//this._Camera.SetPosition(0, 2500, 0);

this._Camera.LookAt = new Vector3(0, 0, 0);
this._Camera.ProjectionType = ProjectionType.PT_ORTHOGRAPHIC;

this._Viewport = this._RenderWindow.AddViewport(this._Camera);
this._Viewport.BackgroundColor = Color.Black;

this._Camera.AspectRatio = (float)_Viewport.ActualWidth/(float)_Viewport.ActualHeight;

Plane p = new Plane();
p.Normal.y = 1;
p.D = 0;

MeshManager.Instance.CreatePlane("plano",
"General", p, 500, 500, 1, 1, true, 1, 1, 1, Vector3.UnitZ);

Entity pEnt = this._SceneManager.CreateEntity("plano_ent", "plano");
SceneNode node = this._SceneManager.GetRootSceneNode().CreateChildSceneNode("plano_node", new Vector3(0, 0, 0));
node.AttachObject(pEnt);

ResourceGroupManager.Instance.addResourceLocation("../Resource", "FileSystem", "General");

ResourcePtr RsPtr = MaterialManager.Instance.Create("plano_mat", "General", true);
Material mat = (new MaterialPtr(RsPtr)).Get();
Technique tec = mat.GetTechnique(0);
Pass pass = tec.getPass(0);

pass.setLightingEnabled(true);
pass.setSceneBlending(SceneBlendType.SBT_ADD);
pass.setDepthWriteEnabled(false);
pass.createTextureUnitState("kiq.jpg");

mat.Load();

pEnt.SetMaterialName(mat.GetName());

this.bRender = true;
this._Root.StartRendering();

Me again =Þ

I solved the problems.

For the Camera I had to call Camera.SetFixedYawAxis(false)

and with the form problem I forgot to call Application.DoEvents in FrameEnded event.

Everthing is ok now.
Thaks for for the help guys.
