复制纹理到纹理 [英] Copy Texture to Texture

问题描述

我已经完成了2个程序来使用共享资源，它们在SlimDX& DirectX10.一个程序将在3D网格上显示共享纹理.第二个程序将图像加载为纹理.到目前为止，每次从新图像更新纹理时，我都需要传递共享处理.

I've done 2 programs to use Shared Resources, running on SlimDX & DirectX10. One program will display the shared texture on a 3D mesh. The 2nd program will load an image as texture. So far I need to pass the shared handled everytime the texture is update from a new image.

现在，有一种方法可以初始化固定大小的共享纹理(Texture2D)，然后每次加载新图像时，我要做的就是将其加载为纹理，然后将其复制到现有纹理中.这样，共享句柄将不会更改，并且我可以节省传递共享句柄的一些开销.对于DirectX9，我确实知道有一个函数可以做到这一点，"StretchRectangle"，但在DirectX10中找不到该函数或类似的东西.

Now, is there a way that I can initialize a fixed size shared texture (Texture2D), then everytime when I load a new image, all I need to do is load it as texture, then copy it to the existing texture. This way the shared handle would not change, and I can save some overhead of passing the shared handle. For DirectX9, I do know there a function to do just that, "StretchRectangle" but I can't find that or anything similar in DirectX10.

中间格式可以是任何东西，甚至可以是表面，只要我将其更新为共享纹理即可.

The intermediate format can be anything, even surface, as long as I get to update it to the shared texture.

谢谢

推荐答案

CopyResource()或CopySubresourceRegion()呢?我不知道SlimDX，但是这些在本机D3D10中应该可以正常工作.

What about CopyResource() or CopySubresourceRegion()? I don't know SlimDX, but these should work fine in native D3D10.
