3D rendering in 5.x... what happened?

[Thomja]

DarkLinux is the shit. I bet he could do some really nice hacks for WoW and even sell them. I do not know much about C++ and I am to lazy to get into it aswell. I'd love to help administrating a hack if he made it! Hes last public hack had a great looking GUI aswell.

Doesn't work at all for me. stuff is behind everything.
Care to explain how you did this exactly ?

Edit: Actually it's not really behind everything but draws as if the Near / FarClip values would be incorrect when they aren't.
Edit2: Viewport MaxZ is different in EndScene than in the function I used to draw in, fixed it. Problem is it overlaps Interface :C

Device.SetTransform(TransformState.World, Matrix.Translation(myPos.X, myPos.Y, myPos.Z));



                ColoredVertex[] triangleVerts = new[]
                    {
                        new ColoredVertex(new Vector3(0f, 0f, 5f), Color.Red.ToArgb()),
                        new ColoredVertex(new Vector3(5f, -5f, 0f), Color.Blue.ToArgb()),
                        new ColoredVertex(new Vector3(-5f, 5f, 0f), Color.Green.ToArgb())
                    };


                var vp = Device.Viewport;
                vp.MinZ = 0f;
                vp.MaxZ = 0.94f;
                Device.Viewport = vp;


                var oldDecl = Device.VertexDeclaration;


                Device.VertexDeclaration = ColoredVertex.GetDecl(Device);
                
                Device.DrawUserPrimitives(PrimitiveType.TriangleList, 1, triangleVerts);


                Device.VertexDeclaration = oldDecl;

This is being called from EndScene.

            Device.SetTransform(TransformState.View, View);
            Device.SetTransform(TransformState.Projection, Projection);
            Device.SetTransform(TransformState.World, Matrix.Identity);


            Device.VertexShader = null;
            Device.PixelShader = null;
            
            //// Required to enabled 3D drawing
            Device.SetRenderState(RenderState.ColorWriteEnable, ColorWriteEnable.All);


            //// Lighting / Alpha Stuff
            Device.SetRenderState(RenderState.Lighting, false);




            Device.SetRenderState(RenderState.CullMode, Cull.None);
            Device.SetRenderState(RenderState.AlphaBlendEnable, true);
            Device.SetRenderState(RenderState.SourceBlend, Blend.SourceAlpha);
            Device.SetRenderState(RenderState.DestinationBlend, Blend.InverseSourceAlpha);


            // Depth
            Device.SetRenderState(RenderState.ZEnable, true);
            Device.SetRenderState(RenderState.ZWriteEnable, true);
            Device.SetRenderState(RenderState.ZFunc, Compare.LessEqual);


            Device.SetTextureStageState(0, TextureStage.ColorOperation, TextureOperation.Disable);
            Device.SetTextureStageState(0, TextureStage.AlphaOperation, TextureOperation.Disable);
            Device.SetTextureStageState(0, TextureStage.ColorArg2, TextureArgument.Texture);

Is that really from EndScene?

Yes. If your depth testing isn't working your nearclip/farclip or your viewport is wrong.
0xAEBC90 - float World::GetNearClip() // 16057, default base
0xAEBC50 - float World::GetFarClip()
See Apoc's post for the viewport.

Problem is it overlaps Interface :C

Yeah I have the same problem. I guess I could hook CWorldSceneRender::Render like you do but I would prefer to keep my code as non game specific as possible. And sometimes I'd actually want to draw above the interface which I assume is not possible from that function, and then I'd need 2 hooks.

I don't think there's much of an issue with drawing above the UI. You could hook the func that does *all* the drawing, but where's the fun in that?

what's the current layout of the camera struct?

long time ago it was
struct SCameraInfo
{
DWORD dwFoo1[2]; // 00
float fPos[3]; // 02
float fViewMat[3][3]; // 05
float zNearPlane; // 14
float zFarPlane; // 15
float fFov; //16
float aspect; // 17
};

then in another thread i found
public struct CameraInfo
{
uint unk0;
uint unk1;
public Vector3 Position;
public Matrix3 Matrix;
public float FieldOfView;
float unk2;
int unk3;
public float NearZ;
public float FarZ;
public float Aspect;
}

but this also doesn't seem to be ok
position, view matrix and fov seem to be ok (fov 1.57 is (2*pi)/4 so this should be right)
but for the adress of nearz, farz and ascpect i only get 0
