能否在取回缓冲?
原标题:Is it possible to view the back buffer while it is being drawn?

Using breakpoints, I m trying to figure out the working of a complex app which uses DirectX buffers.
I see many places where the Blt command draws to the back buffer/surface, and I need to know what exactly it is drawing at that point in the code.

Unfortunately, I m able to see what was drawn only when the entire frame is drawn and the buffers are flipped.

难道没有办法在推测后缓冲/表面? 在此之前,它会失败吗?

问题回答

您可使用PIX作为Windows,在万国邮联中解冻问题或工作瓶颈。 PIX是一个简介员,将非常详细地介绍每一步骤中发生的情况。

因此,它将允许你看到在后方缓冲地带每发出3D号直接呼吁。 你们还可以在最后形象中选择一个特定的子,并看到这片雕像历史上发生的情况(例如,斜体适用于它)。

这里有两部辅导:
