ProfileIn the previous tutorial, we built a minimal Direct3D 11 application that was used to output a single color on a window. In this tutorial, we will extend the application to render a single-color triangle on the screen. We'll associate the triangle with the process of setting up the data mechanism.The output of this tutorial is to render a triangle in the center of the window.Resource Directory(SDK root) \samples\c++\direct3d11\tutorials\tutoria

I. Prerequisites 1. Surface The surface is a pixel matrix used by direct3d to store 2D image data. Width and height are measured in pixels, and pitch is measured in bytes. The interface idirect3dsurface is used to describe the surface. Lockrect: This method is used to obtain the pointer pointing to the surface storage area. You can perform read/write operations on each pixel through pointer operations; Unlockrect: Used in pairs. The call lock must

This is done by passing the depth template View to the third parameter of the omsetrendertargets function. g_pImmediateContext->OMSetRenderTargets( 1, g_pRenderTargetView, g_pDepthStencilView );    Like the rendering target, we must also clear the depth buffer before rendering. This ensures that the depth value of the previous frame does n

The render tab always shows the contents of the back buffer as of the currently-selected event. so you can watch your frame render bit by bit, by selecting each draw call. the "d Down" toolbar button makes this easier; it moves to the next draw call. (but see below for a note about programs that change the render target ). When a draw call is selected, the mesh tab shows useful information about the vertex data that was processed by the gr

3D Programming: The Direct3D Graphics Pipeline

Direct3D 11 Graphics pipeline PCs typically have two processors: CPUs and GPU, and you need to write code for each processor. These two parts have completely different schemas and instruction sets. In graphics programming, you need to write software for all two processors, use common languages for CPU applications, such as C + +, and HLSL for GPU. DirectX is the bridge between systems. Most of the articles on graphic programming focus on the CPU or t
