Going from DX9 to DX10
July 27, 2009 – 10:51 pm by roderickGoing from DirectX 9 to DirectX 10 in C++:
DX10 (at least the version of August 2007) seems to really dislike rendering to buffers that aren’t powers of two – e.g. rendering to a HDR buffer that’s 1280 by 720!
Here’s a table of roughly corresponding DX9 and DX10 expressions:
| D3DFORMAT | -> | DXGI_FORMAT |
| D3DFMT_… | -> | DXGI_FORMAT_… |
| D3DUSAGE_… | -> | D3D10_USAGE_… |
| D3DVERTEXELEMENT9 | -> | D3D10_INPUT_ELEMENT_DESC |
| CreateVertexDeclaration | -> | CreateInputLayout |
| OnLostDevice | -> | not used? |
| D3DXCreateTexture | -> | ID3D10Device::CreateTexture1D, CreateTexture2D |
| D3DXCreateVolumeTexture | -> | ID3D10Device::CreateTexture3D |
| LockRect | -> | Map |
| UnlockRect | -> | Unmap |
| D3DLOCKED_RECT | -> | D3D10_MAPPED_TEXTURE2D |
| D3DLOCKED_BOX | -> | D3D10_MAPPED_TEXTURE3D |
| SetVertexDeclaration | -> | IASetInputLayout |
| ID3DXEffect::SetTexture | -> | ID3D10EffectShaderResourceVariable::SetResource |
| ID3DXEffect::SetVector | -> | ID3D10EffectVectorVariable::SetFloatVector |
| ID3DXEffect::SetFloat | -> | ID3D10EffectFloatVariable::SetFloat |
| D3DQUERYTYPE_ | -> | D3D10_QUERY_DESC |
| D3DXCreateTextureFromFile | -> | D3DX10CreateTextureFromFile |
| LPDIRECT3DSURFACE9, IDirect3DSurface9 * | -> | ID3D10RenderTargetView*, ID3D10DepthStencilView* |
| LPDIRECT3DTEXTURE9, IDirect3Texture9 | -> | ID3D10Texture1D, ID3D10Texture2D |
| D3DXHANDLE (for shader variables) | -> | ID3D10EffectScalarVariable*, ID3D10EffectVectorVariable*, etc. |
| LPDIRECT3DQUERY9, IDirect3DQuery9* | -> | ID3D10Query* |
| vs_1_1, etc. | -> | Not Supported |
| technique | -> | technique10 |
| cullmode=none | -> | SetRasterizerState( RenderNoCull ); |
| ZEnable = true; | -> | SetDepthStencilState( DisableDepth, 0 ); |
| AlphaBlendEnable = false; | -> | SetBlendStateNoBlend, float4( 0.0f, 0.0f, 0.0f, 0.0f ), 0xFFFFFFFF ); |
