Basic Flight Simulation

September 12, 2005


Objectives

Practice in using our camera model and basic terrain rendering


Two Cameras

First camera – first person viewbehind an airplane

Second camera – whole viewcorner of the terrain


Airplane (1)

ID3DXMesh interfacecreating an empty mesh

creating an object and loading the geometric data from X file

HRESULT D3DXLoadMeshFromX (LPCSTR pFilename,DWORD Options,LPDIRECT3DDEVICE9 pDevice,LPD3DXBUFFER* ppAdjacency,LPD3DXBUFFER* ppMaterials,LPD3DXBUFFER* ppEffectInstances,PDWORD pNumMaterials,LPD3DXMESH* ppMesh

);

HRESULT D3DXLoadMeshFromX (LPCSTR pFilename,DWORD Options,LPDIRECT3DDEVICE9 pDevice,LPD3DXBUFFER* ppAdjacency,LPD3DXBUFFER* ppMaterials,LPD3DXBUFFER* ppEffectInstances,PDWORD pNumMaterials,LPD3DXMESH* ppMesh

);

HRESULT ID3DXCreateMeshFVF (DWORD NumFaces,DWORD NumVertices,DWORD Options,DWORD FVF,LPDIRECT3DDEVICE9 pDevice,LPD3DXMESH* ppMesh

);

HRESULT ID3DXCreateMeshFVF (DWORD NumFaces,DWORD NumVertices,DWORD Options,DWORD FVF,LPDIRECT3DDEVICE9 pDevice,LPD3DXMESH* ppMesh

);


Airplane (2)

ID3DXMesh interface (cont.)reorganizing the vertices and indices of a mesh to render it more efficiently

drawing the triangles of a particular subset specified

ex) drawing all subsets of a mesh

HRESULT ID3DXMesh::OptimizeInplace (DWORD Flags,CONST DWORD* pAdjacencyIn,DWORD* pAdjacencyOut,DWORD* pFaceRemap,LPD3DXBUFFER* ppVertexRemap

);

HRESULT ID3DXMesh::OptimizeInplace (DWORD Flags,CONST DWORD* pAdjacencyIn,DWORD* pAdjacencyOut,DWORD* pFaceRemap,LPD3DXBUFFER* ppVertexRemap

);

HRESULT ID3DXMesh::DrawSubset(DWORD AttribId);HRESULT ID3DXMesh::DrawSubset(DWORD AttribId);

for(int i=0; i<numSubsets; i++) {Device->SetMaterial( mtrls[i] );Device->SetTexture( 0, textures[i] );Mesh->DrawSubset(i);

}
