有没有办法查看D3D设备当前的全部渲染状态？

[mmmcd]

某种情况下渲染总是有问题，而通过PIX看到的状态并不完整
有什么方法能看清所有细节？
通过CreateStateBlock获取的状态有没有办法看到详细内容？
LPDIRECT3DSTATEBLOCK9 pSBlock;
device->CreateStateBlock(D3DSBT_ALL, &pSBlock);

[mmmcd]

搞定结贴

我的状态设置都是对的，但ID3DXSprite::Begin里还有个玄机：
SetVertexShader(NULL);
SetPixelShader(NULL);

加上即OK

晕

[mmmcd]

晕
MS文档里居然不说
最后还是用pix看出来的

在PIX里，你看到凡是IDirect3DDevice9::xxx 前面都有蓝色的pDevice的地址，你双击那个地址会弹出Device的属性页，里面不是有Input State, Tessellation Stae, Vertx State, Pixel State, Output State么，这些属性还不够么？

[xingzhe2001]

我这里你需要的那些状态都可以看到阿

[xingzhe2001]

拷过来一些，你看这些是固定管线光和材质的属性。

楼主，你看看那个PIX的高级应用
可能有你想要看的东西

我机器上的截图

先谢谢各位
我的最终目的是想解决一下这个问题

HRESULT hr = m_sprite->Begin(D3DXSPRITE_DONOTSAVESTATE);
m_sprite->End();
//之后我只用device,画任何东西都正常

而如果把m_sprite->Begin和end去掉后，用device怎么都画不出来
我按照DX文档，想通过下面的设状态来取代：m_sprite->Begin(D3DXSPRITE_DONOTSAVESTATE);

        m_device->SetRenderState(D3DRS_ALPHABLENDENABLE, TRUE);
        m_device->SetRenderState(D3DRS_ALPHAFUNC, D3DCMP_GREATER);
        m_device->SetRenderState(D3DRS_ALPHAREF, 0x00);
        m_device->SetRenderState(D3DRS_ALPHATESTENABLE, FALSE);
        m_device->SetRenderState(D3DRS_BLENDOP, D3DBLENDOP_ADD);
        m_device->SetRenderState(D3DRS_CLIPPING, TRUE);
        m_device->SetRenderState(D3DRS_CLIPPLANEENABLE, FALSE);
        m_device->SetRenderState(D3DRS_COLORWRITEENABLE,
            D3DCOLORWRITEENABLE_ALPHA | D3DCOLORWRITEENABLE_BLUE | D3DCOLORWRITEENABLE_GREEN | D3DCOLORWRITEENABLE_RED);
        m_device->SetRenderState(D3DRS_CULLMODE, D3DCULL_NONE); 
        m_device->SetRenderState(D3DRS_DESTBLEND, D3DBLEND_INVSRCALPHA);
        m_device->SetRenderState(D3DRS_DIFFUSEMATERIALSOURCE, D3DMCS_COLOR1);
        m_device->SetRenderState(D3DRS_ENABLEADAPTIVETESSELLATION, FALSE);
        m_device->SetRenderState(D3DRS_FILLMODE, D3DFILL_SOLID);
        m_device->SetRenderState(D3DRS_FOGENABLE, FALSE);
        m_device->SetRenderState(D3DRS_INDEXEDVERTEXBLENDENABLE, FALSE);
        m_device->SetRenderState(D3DRS_LIGHTING, FALSE);
        m_device->SetRenderState(D3DRS_RANGEFOGENABLE, FALSE);
        m_device->SetRenderState(D3DRS_SEPARATEALPHABLENDENABLE, FALSE);

        m_device->SetRenderState(D3DRS_SHADEMODE, D3DSHADE_GOURAUD);
        m_device->SetRenderState(D3DRS_SPECULARENABLE, FALSE);
        m_device->SetRenderState(D3DRS_SRCBLEND, D3DBLEND_SRCALPHA);
        m_device->SetRenderState(D3DRS_SRGBWRITEENABLE, FALSE);
        m_device->SetRenderState(D3DRS_STENCILENABLE, FALSE);
        m_device->SetRenderState(D3DRS_VERTEXBLEND, FALSE);
        m_device->SetRenderState(D3DRS_WRAP0, 0);

        m_device->SetTextureStageState(0, D3DTSS_ALPHAARG1, D3DTA_TEXTURE);
        m_device->SetTextureStageState(0, D3DTSS_ALPHAARG2, D3DTA_DIFFUSE);
        m_device->SetTextureStageState(0, D3DTSS_ALPHAOP, D3DTOP_MODULATE);
        m_device->SetTextureStageState(0, D3DTSS_COLORARG1, D3DTA_TEXTURE);
        m_device->SetTextureStageState(0, D3DTSS_COLORARG2, D3DTA_DIFFUSE);
        m_device->SetTextureStageState(0, D3DTSS_COLOROP, D3DTOP_MODULATE);
        m_device->SetTextureStageState(0, D3DTSS_TEXCOORDINDEX, 0);
        m_device->SetTextureStageState(0, D3DTSS_TEXTURETRANSFORMFLAGS, D3DTTFF_DISABLE);
        m_device->SetTextureStageState(1, D3DTSS_ALPHAOP, D3DTOP_DISABLE); 
        m_device->SetTextureStageState(1, D3DTSS_COLOROP, D3DTOP_DISABLE);

用device仍旧画不东西

[xingzhe2001]

Pix里有线索么？

你在d3d control panel 里把 Debug Output Level改称More, 选择 Use Debug Version of Direct3D 9, 看看调试输出窗口有什么线索。

[xingzhe2001]

zbuffer clear得是否正确？Pixel里面点像素右键->debug 应该能看到详细的信息，为什么没画出来等。

[张赐]

不是就在beginScene和EndScene之间画就能画出东西来吗

[mmmcd]

甚至写成：

m_sprite->Begin(D3DXSPRITE_DONOTSAVESTATE);
m_sprite->end();
按照DX文档ID3DXSprite::Begin那块表格列出的状态，用device一条条设一遍
///后面用divce画一切正常

//注释掉m_sprite
//m_sprite->Begin(D3DXSPRITE_DONOTSAVESTATE);
//m_sprite->end();
按照DX文档ID3DXSprite::Begin那块表格列出的状态，用device一条条设一遍
///后面用divce画全不正常

不知道ID3DXSprite::Begin除了设置状态还做了什么事情？

[张赐]

ID3DXSprite::Begin
就是让设备做好画精灵的准备嘛
楼主可能其他代码有问题

[xingzhe2001]

This method must be called from inside a IDirect3DDevice9::BeginScene . . . IDirect3DDevice9::EndScene sequence. ID3DXSprite::Begin cannot be used as a substitute for either IDirect3DDevice9::BeginScene or ID3DXRenderToSurface::BeginScene.

[mmmcd]

m_sprite->Begin(D3DXSPRITE_DONOTSAVESTATE);
m_sprite->End();
///后面用divce画一切正常

[mmmcd]

上图上真相

除了红圈部分，其他地方跟MS文档吻合

[xingzhe2001]

那楼主画别的物体没有调用过SetVertexShader()?
