一直不后缀unorm和snorm什么意思，今天看introduction dx11 忽然明白，就是类型+是否归一化，（还有个typeless）DXGI_FORMAT_R32G32B32_FLOAT: Each element has three 32-bit floating-point components.   DXGI_FORMAT_R16G16B16A16_UNORM: Each

Vertex positions leaving the geometry shader must be transformed to homogeneous clip space.

5.5.2.6 Primitives with Adjacency A triangle list with adjacency is where, for each triangle, you also include its three neighboring triangles called adjacent triangles; see Figure 5.14b to observe

5.6.3.6 XMMatrixPerspectiveFovLH A perspective projection matrix can be built with the following XNA Math function: XMMATRIX XMMatrixPerspectiveFovLH( // returns projection matrix FLOAT FovAngleY, //

The XNA Math library provides the following function for computing the view matrix based on the just described process: XMMATRIX XMMatrixLookAtLH( // Outputs resulting view matrix V FXMVECTOR EyePosit

32-Bit Color To represent a color with 32-bits, a byte is given to each component. Since each color is given an 8-bit byte, we can represent 256 different shades for each color component—0 being no

Modify the previous exercise solution by disabling the ALT-ENTER functionality to switch between full screen and windowed mode; use the IDXGIFactory::MakeWindowAssociation method and specify the DXG

Texture Resource Views A texture can be bound to different stages of the rendering pipeline; a common example is to use a texture as a render target (i.e., Direct3D draws into the texture) and as a sh

D3D_DRIVER_TYPE_REFERENCE: Creates a so-called reference device. The reference device is a software implementation of Direct3D with the goal of correctness (it is extremely slow because it is a softwa

4.1.8 Multisampling in Direct3D In the next section, we will be required to fill out a DXGI_SAMPLE_DESC structure. This structure has two members and is defined as follows:typedef struct DXGI_

There is nothing that limits us to one parameter. We will need to combine shadow quality, textures, and the number of lights all together so the vertex and pixel shaders would look like the followin
