Why are the D3D12 samples using WM_PAINT?

If you're trying to program a game, you really shouldn't wait around for WM_PAINT signals from the O/S to draw. You should repeatedly draw as quickly as possible. Why then in the D3D sample code is rendering happening in WM_PAINT? How can I rework…

Setting multiple descriptors in a descriptor range in Direct3D 12

First of all, my understanding of a descriptor range is that I can specify multiple buffers (constant buffers in my case) that a shader may use, is that correct? If not, then this is where my misunderstanding is, and the rest of the question will…

Is there something like vkCmdBlitImage for D3D12?

I'd like to create a mipmap chain for a 2D texture by blitting the base image into mip levels. In Vulkan, vkCmdBlitImage can be used to do this while linearly filtering the image (see another question). How can I achieve the same in D3D12?

Question about D3D12 vertex drawing order

I want to draw a rectangle using D3D12, but why do I need to set the 'N' shaped vertex order to draw it correctly? I am not quite familiar with this aspect. struct GRS_VERTEX { XMFLOAT4 Position; XMFLOAT4 Color; }; GRS_VERTEX…

Using the same buffer as input and output for a compute shader

Hopefully a very simple question! I have a particle system that I'm updating with a compute shader (just updating a buffer with position data). Right now I'm reading from an input buffer and writing to a different output buffer (that will be the…
