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

[Jadd]

For some reason, ever since the first MoP pre-patch, I have not been able to render 3D.

My camera information is correct (including world, view, and projection matrixes). I spoke to Nesox and he is having the same issue. Does anyone know what happened? I'm sure it's something simple we are missing.

Thanks in advance

God knows, I've had this issue in the first public mop patch. It wouldn't appear until I opened and closed the Wow console.

I'm not having any issues in the current patch though, I don't think I made any changes to my code, I'll look into it once I get home.

No problems for me...

It wouldn't appear until I opened and closed the Wow console.

We had the same issue (with 2D drawings too). We managed to fix this by setting the COLORWRITEENABLE render state to 0xF - it fixed our issue with 2D drawings, but still no luck with 3D drawings; just FYI in case this ever comes up again.

DarkLinux, mind sharing some code? I'm sure you'll recieve much love for it

[Nesox]

Finally got it working, thx Jadd

What are you hooking to draw? I am using SetViewport...

You're hooking SetViewport...? I don't understand..

[DarkLinux]

I detour it to draw in 3d.. I can help you when I get off work..

I haven't experienced any issues with mine. I'm calling this from Endscene using D3D9;

  CameraInfo cam = Helper.Magic.ReadStruct<CameraInfo>(camPtr);
            Vector3 eyePt = cam.Pos;
            Vector3 lookAtPt = cam.Pos + cam.ViewMat1;
            Vector3 upPt = new Vector3(0, 0, 1);


            Matrix matWorld = Matrix.Translation(target.X, target.Y, target.Z);
            Matrix matView = Matrix.LookAtRH(eyePt, lookAtPt, upPt);
            Matrix matProj = Matrix.PerspectiveFovRH(cam.FieldOfView * 0.6f, (float)(1.335), cam.NearPlane, cam.FarPlane);


            Device.SetTransform(TransformState.World, matWorld);
            Device.SetTransform(TransformState.View, matView);
            Device.SetTransform(TransformState.Projection, matProj);


            Device.VertexShader = null;
            Device.PixelShader = null;
            Device.SetRenderState(RenderState.AlphaBlendEnable, true);
            Device.SetRenderState(RenderState.BlendOperation, BlendOperation.Add);
            Device.SetRenderState(RenderState.DestinationBlend, Blend.InverseSourceAlpha);
            Device.SetRenderState(RenderState.SourceBlend, Blend.SourceAlpha);
            Device.SetRenderState(RenderState.Lighting, 0);
            Device.SetTexture(0, null);
            Device.SetRenderState(RenderState.CullMode, Cull.None);


            Result res = Device.DrawUserPrimitives(PrimitiveType.LineList, (vertices.Count() / 2), vertices);

We were hooking CWorldSceneRender::Render (thx to Bananenbrot) back in 4.3.

[abdula123]

still use same EndScene, Present and Reset hooks as in 4.x

only thing added in 5.0.4 is device.SetRenderState(D3DRS.COLORWRITEENABLE, RedGreenBlueAlpha)
without this setting only 2d font drawing was rendered, but no 3d primitives.


rendering, EndScene hook:

        self.stateblock.Capture()

        self.device.SetVertexShader(0)
        self.device.SetPixelShader(0)
        self.device.SetFVF(D3DFVF.XYZ | D3DFVF.DIFFUSE)

        # ИЗ-ЗА ЭТОГО ГАДСТВА НИЧЕГО НЕ РИСОВАЛОСЬ.
        RedGreenBlueAlpha = 15
        self.device.SetRenderState(D3DRS.COLORWRITEENABLE, RedGreenBlueAlpha)

        z_disable = True
        if z_disable:
            self.device.SetRenderState(D3DRS.ZENABLE, D3DZB.FALSE)
            self.device.SetRenderState(D3DRS.STENCILENABLE, 0)
        else:
            self.device.SetRenderState(D3DRS.ZENABLE, D3DZB.TRUE)
            self.device.SetRenderState(D3DRS.ZWRITEENABLE, D3DZB.TRUE)
            self.device.SetRenderState(D3DRS.ZFUNC, D3DCMP.LESSEQUAL)
            self.device.SetRenderState(D3DRS.STENCILENABLE, 1)

        self.device.SetRenderState( D3DRS.SPECULARENABLE, 0)
        self.device.SetRenderState( D3DRS.LIGHTING, 0 )
        self.device.SetRenderState( D3DRS.CULLMODE , D3DCULL.NONE)
        self.device.SetRenderState( D3DRS.ANTIALIASEDLINEENABLE, 1)
        self.device.SetRenderState(D3DRS.FOGENABLE, 0)


        self.device.SetRenderState( D3DRS.ALPHABLENDENABLE, 1 )
        self.device.SetRenderState( D3DRS.SRCBLEND, D3DBLEND.SRCALPHA )
        self.device.SetRenderState( D3DRS.DESTBLEND, D3DBLEND.INVSRCALPHA )

        Viewport = D3DVIEWPORT9()
        self.device.GetViewport(byref(Viewport))
        Viewport.MinZ = 0
        Viewport.MaxZ = 0.94
        self.device.SetViewport(byref(Viewport))

        self.device.SetTransform(D3DTS.WORLD, byref(IdentityMatrix))
        self.device.SetTransform(D3DTS.VIEW, byref(ViewMatrix(cam)))
        self.device.SetTransform(D3DTS.PROJECTION, byref(ProjectionMatrix(cam)))

        try:
            #THERE IS MY RENDERING DONE
        finally:
            self.stateblock.Apply()

init/deinit, Reset hook:

init:
        self.stateblock = POINTER(IDirect3DStateBlock9)()
        self.device.CreateStateBlock(1, byref(self.stateblock))
deinit:
        self.stateblock.Release()

You cannot draw real 3D stuff with Z-Tests from EndScene...

@_Mike
Is that really from EndScene?

[BuloZB]

guys this topic help me a lot, you dont know how much

thx
