I understood that fixfuncshader is directly transforming vectors from world to clip.
But I now got a hierarchy. How do I define the following variables?
- matView
- matWorldView
- matWorldViewIT
- matViewIT
- matWorldViewProj
virtual void Render()
{
CObjects::Render();
g_pEffect->SetTechnique(g_pEffect->GetTechniqueByName("basic_with_shader"));
D3DXMATRIXA16 compMat, invMat;
g_pEffect->SetMatrixTranspose("matView", &g_Cam[iCurCam].GetViewMatrix());
D3DXMatrixMultiply(&compMat, &m_matWorld, &g_Cam[iCurCam].GetViewMatrix());
g_pEffect->SetMatrixTranspose("matWorldView", &compMat);
D3DXMatrixInverse(&invMat, NULL, &compMat);
D3DXMatrixTranspose(&invMat, &invMat);
g_pEffect->SetMatrixTranspose("matWorldViewIT", &invMat);
D3DXMatrixInverse(&invMat, NULL, &g_Cam[iCurCam].GetViewMatrix());
D3DXMatrixTranspose(&invMat, &invMat);
g_pEffect->SetMatrixTranspose("matViewIT", &invMat);
D3DXMatrixMultiply(&compMat, &compMat, &g_Cam[iCurCam].GetProjMatrix());
g_pEffect->SetMatrixTranspose("matWorldViewProj", &compMat);
g_pEffect->SetMatrixTranspose("matProj", &g_Cam[iCurCam].GetProjMatrix());
m_Mesh->UpdateFrame(NULL, &m_matWorld);
m_Mesh->RenderTransparent();
}
