如何尽可能高效绘制图形尽可能在WPF [英] How to draw graphics as efficiently as possible in WPF

问题描述

我创建了一个工具，在很大程度上依赖于图的节点树。当前实现是用Java做的，我将它移植到C＃的通用代码库，因此它可以通过各种渲染实现中使用，也因为我想利用WPF的强大的用户友好的界面。

I am creating a tool which relies heavily on graph-node trees. The current implementation is done in Java and I'm porting it to a generic code-base on C#, so it can be used by various rendering implementations and also because I want to use the power of WPF for a user-friendly interface.

浏览逛了一天后，我碰到的各种方法来绘制通过WPF的矢量图形。

After browsing around for a day, I came across various methods to draw Vector-graphics through WPF.

< A HREF =http://www.fernicola.org/loquitor/index.php?/archives/17-WPF-Pick-Your-API-Abstraction.html>这家伙讲WPF内对不同层次开发人员可以选择。正如我想用WPF纯粹是为了他的第一个渲染，我想在可视层的工作。

This guy speaks about different layers within WPF developers can choose from. As I want to use WPF PURELY for his rendering at first, I want to work on the "Visual Layer".

然后我遇到事情喜欢传来：
DrawingVisual ，
的GeometryDrawing ，
的 FrameworkElement的 / 的UIElement /形状

I then came across things like: DrawingVisual, GeometryDrawing, FrameworkElement / UIElement / Shapes

所以，我有点被所有不同的实现，最终做同样的方式完全不同淹没。

So, I'm a bit overwhelmed by all the different implementations that do eventually the same in totally different ways.

该图的节点库已经被移植到C＃已经与所有它的逻辑（包括碰撞检测，并拖动鼠标）。因为它是在头脑与图形的渲染制作（如XNA，SlimDX，OpenTK等），这将是在性能实现一个WPF渲染器（如，它会画什么图形库告诉它条款的最佳方式画？

The Graph-Node library has been ported to C# already with all it's logic (including collision detection and dragging with mouse). As it is made with graphic-renderers in mind (like XNA, SlimDX, OpenTK, etc.), what would be the best way in terms of performance to implement a WPF renderer (as in, it will draw whatever the graph library tells it to draw?

基本上，导致WPF控件作为画布，但它必须是超轻量级，而不是有除了提供我的方式来得出任何整齐的WPF功能我的圈子，线条等造型：）

Basically, the resulting WPF control acts as a canvas, but it has to be SUPER lightweight and not have any neat WPF features besides providing me a way to draw my circles, lines and other shapes :)

编辑：

我基本上想知道：什么是路要走？我是否延长帆布为主机为我的图形，然后加我UIElement的自定义实现？或者，我可以有一个类可以借鉴一切（如在一百万超超图）。就像在GDI或Java的喷漆方法（它给出了一个Graphics对象做的一切）压倒一切的OnPaint。

I basically want to know: What is the way to go? Do I extend Canvas as "Host" for my graphics and then add my custom implementation of a UIElement? Or can I have one class which can draw EVERYTHING (as in, one mega super ultra graphic). Much like overriding OnPaint in GDI or Paint-method in Java (which gives a Graphics object to do everything with).

推荐答案

我倒是推荐阅读优化性能：2D图形和图像（死链接 - 读通过互联网档案） -

I'd recommend reading Optimizing Performance: 2D Graphics and Imaging (dead link -- readable via Internet Archive) -

基本上，图的物体会比图形一般。这可能是你想要使用什么样的。

Basically, Drawing objects will be lighter weight than Shapes, in general. This is probably what you want to use.
