view matrix
Author
hi guys ,
can anyone tell me how to use the view matrix to get camera movement. when i am compiling the following code only one frame is showing . the code is below
other necessary functions are there
THANKS TO ANYONE WHO ANSWERS IN ADVANCE
VOID Render()
{
g_pd3dDevice->Clear( 0, NULL, D3DCLEAR_TARGET|D3DCLEAR_ZBUFFER,
D3DCOLOR_XRGB(0,0,0), 1.0f, 0 );
D3DLIGHT8 light;
ZeroMemory( &light, sizeof(D3DLIGHT8) );
light.Type = D3DLIGHT_POINT;
light.Diffuse.r = 1.0f;
light.Diffuse.g = 0.0f;
light.Diffuse.b = 0.2f;
light.Position.x = 0.0f;
light.Position.y = 1.0f;
light.Position.z = -80.0f;
light.Range = 1000.0f;
g_pd3dDevice->SetLight( 0, &light );
g_pd3dDevice->LightEnable( 0, TRUE);
D3DXMATRIX matView, matProj;
D3DXVECTOR3 eyepoint,lookat;
D3DXVECTOR3 upvect(0.0f,1.0f,0);
eyepoint.x = 0.0f;
eyepoint.y = 25.0f;
lookat.x = 0.0f;
lookat.y = 25.0f;
g_pd3dDevice->BeginScene();
for(int m = 0;m<345;m++)
{
eyepoint.z = 5.0f+m;
lookat.z =-100.0f;
D3DXMatrixLookAtLH( &matView,&eyepoint,&lookat,&upvect);
g_pd3dDevice->SetTransform( D3DTS_VIEW, &matView );
D3DXMatrixPerspectiveFovLH( &matProj, D3DX_PI/4, 1.0f, 1.0f, 10000.0f );
g_pd3dDevice->SetTransform( D3DTS_PROJECTION, &matProj );
for( DWORD i=0; iSetMaterial( &g_pMeshMaterials );
g_pd3dDevice->SetTexture( 0, g_pMeshTextures );
g_pMesh->DrawSubset( i );
}
g_pd3dDevice->EndScene();
}
g_pd3dDevice->Present( NULL, NULL, NULL, NULL );
}

Shouldn''t the g_pd3dDevice->BeginScene() be in the loop
for every frame you need to have a beginscene and a endscene
the beginscene is outside the loop scope and because of that you can''t see all the frames, only the first one

hi
even when i keep the begin scene in the loop only one frame is getting displayed. updated code is here
for(int m = 0;m<345;m++)
{
g_pd3dDevice->BeginScene();
eyepoint.z = 5.0f+m;
lookat.z =-100.0f;
D3DXMatrixLookAtLH( &matView,&eyepoint,&lookat,&upvect);
g_pd3dDevice->SetTransform( D3DTS_VIEW, &matView );
D3DXMatrixPerspectiveFovLH( &matProj, D3DX_PI/4, 1.0f, 1.0f, 10000.0f );
g_pd3dDevice->SetTransform( D3DTS_PROJECTION, &matProj );
for( DWORD i=0; i {
g_pd3dDevice->SetMaterial( &g_pMeshMaterials );
g_pd3dDevice->SetTexture( 0, g_pMeshTextures );<br> <br> <br> g_pMesh->DrawSubset( i );<br> }<br> <br> <br> g_pd3dDevice->EndScene();<br> <br> }<br> g_pd3dDevice->Present( NULL, NULL, NULL, NULL );<br>}<br> </i>
