图形应用程序中的C ++ vs.C＃。 [英] C++ vs.C# in a graphics app.

问题描述

我们计划开发一款应用。这将涉及很多图形操作，如

打开，缩放旋转等。

并且由于过滤器，噪音校正将会有很多数学运算

等。在图像上。

与ac＃和win32 c ++或

托管c ++代码会有太多的性能差异吗？

感谢您的帮助

Hi,
we plan to develop an app. that will involve lots graphics operations like
open, zoom rotate ect.
and there will be a lot of math in it because of filters ,noise corrections
ect. on image.
Will there be too much performance difference with a c# and win32 c++ or
managed c++ code?
thanks for help

Geranlly C ++非IL这样的事情要快得多。您应该使用非IL构建一个带有

托管导出的ASM，并使用C＃。

我们发现C＃的速度非常快，即使对于低级别的像素运行，只要您处理像素阵列之类的东西，而不是高级API。 C＃中的不安全代码不一定比数组

像素快。告诉您具体案例的唯一方法是制定具体的

基准。

We have found C# to be surprisingly fast even for low level pixel
operations, as long as you work with things like arrays of pixels, and not
high level APIs. Unsafe code in C# is not necessarily faster than an array
of pixels. The only way to tell for your specific case is to make specific
benchmarks.

对于那种操作，c＃肯定比java快吗？

Is c# definitely faster than java for that kind of operations?
