A lot of Problems... =D

[Draven]

Hi Guys,

i'm actually working on a D3D9 Project... who's wondering? :rolleyes:

 

I admit that this is my first project in DirectX, so i have a lot of questions for y'all.

 

But first of all, i'll give you some information about the project.

So, it's a kind of 3D-Mapviewer for the Game "Anno 1503" alias knows as "1503 A.D."!

 

Here's a screenshot of the current version:

The program uses a class to load the "*.scp" - File and to create a 2D-Bitmap in memory, which is serving to create a Heightmap for the 3D-Mesh.

 

And now my problems are:

- I want to implement a first-person camera movement, because the actual one is very untidy and unwieldy.

 

        wMatrix = Matrix.Identity
       wMatrix = Matrix.Translation(New Vector3(__CamX, __CamY, __CamZ))
       wMatrix = Matrix.Multiply(wMatrix, Matrix.RotationZ(__AngleZ))
       wMatrix = Matrix.Multiply(wMatrix, Matrix.RotationX(__AngleX))
       wMatrix = Matrix.Multiply(wMatrix, Matrix.RotationY(__AngleY))
       wMatrix = Matrix.Multiply(wMatrix, Matrix.Scaling(__ScaleZ, __ScaleZ, __ScaleZ))

       __device.Transform.View = Matrix.LookAtLH(New Vector3(-(_TWIDTH * 0.5), _TWIDTH * 0.5, 150 + __CamZ), _
                                       New Vector3(_TWIDTH * 0.5 + __CamX, _TWIDTH * 0.5 + __CamY, 0), _
                                      New Vector3(0, 1, 0))

       __device.Transform.World = wMatrix

So, what changes should i make to strafe left/right and forward/backward.

I guess it has something to do with the "Matrix.Translation"... but i can't get it working and i can't find a really good tutorial or example for this stuff... :(

 

And my last question for the moment is:

"How do I convert a pick ray's intersection into a 3D World Space (x,y,z) coordinate??"

 

All tutorials and examples that i've found are covering on the Mesh-Class, but i create the landscape-mesh on the fly in an array...

 

I'm grateful for every answer and suggestion... :D

And a big sorry for my bad english-grammar... :o
