XNA在显卡上 [英] XNA on graphics card

问题描述

（如何将工作负载移动到显卡上）

所有的图形都是由图形卡自动绘制的。在XNA中没有软件渲染器模式。

XNA设置的方式大多数几何体都被传输到图形卡顶点缓冲区对象。然后，固定的管线近似或着色器将被显卡应用于数据并显示在屏幕上。

简而言之：如果您希望对数据执行操作在显卡上。使用顶点和像素着色器。

您还应该深入研究图形管道的细节更好地理解图形卡的工作方式。

How can I program graphics on a graphics card with XNA?

(How do I move the workload onto the graphics card)

解决方案

Explained in a very simplified way:

All of the graphics are automatically drawn by the graphics card. There is no software rendererer mode in XNA.

The way XNA is set up most geometry is transferred to the graphics card Vertex Buffer Objects. A fixed pipeline approximization or shaders are then applied to the data by the graphics card and displayed on screen.

In short: If you want to do operations on your data while it's on the graphics card. Use vertex and pixel shaders.

EDIT:

You should also delve into the details of the graphics pipeline to understand better how graphic cards work.
