i am trying to get a simple rectangle being rendert in my directx 10 window.
In directx 9 i used following code which worked just fine:
#define D3DFVF ( D3DFVF_XYZRHW | D3DFVF_DIFFUSE )struct vertex{ float x,y,z,rhw; DWORD dwColor;};DWORD _fvf;IDirect3DPixelShader9* tempp;IDirect3DVertexShader9* tempv;HRESULT DrawPrimitiveLine( LPDIRECT3DDEVICE9 pDevice, float fromX, float fromY, float toX, float toY, DWORD dwColor ){ vertex fillline[2] = { { (float)fromX, (float)fromY, 1.0f, 0.0f, dwColor}, { (float)toX, (float)toY, 1.0f, 0.0f, dwColor} }; HRESULT iRet = S_OK; pDevice->GetFVF(&_fvf); pDevice->GetPixelShader(&tempp); pDevice->GetVertexShader(&tempv); pDevice->SetTexture(0, NULL); pDevice->SetPixelShader(NULL); pDevice->SetRenderState(D3DRS_CLIPPING,FALSE); pDevice->SetFVF(D3DFVF); iRet = pDevice->DrawPrimitiveUP(D3DPT_LINESTRIP, 1, fillline, sizeof(vertex)); pDevice->SetVertexShader(tempv); pDevice->SetPixelShader(tempp); pDevice->SetFVF(_fvf); return iRet;}As you see i dont need any pixelshaders or any advanced stuff (in my view). Just a simple
code which draws stuff at screenPositions i want. Nothing in 3d space either.
Now i converted the code to something like this based on a tutorial from directxtutorial.com
To be honest, i cannot seem to get this to work. Also tried it based on sprites but that doesnt
give me any success either. Could somebody point this out any further?
