在SlimDX（D3D9）中启用antialising [英] Enabling antialising in SlimDX (D3D9)

问题描述

我想在绘制如下图所示的三角形时启用抗锯齿功能：

我在XNA上找到了一种方法来处理本页面，但我想用 SlimDX 完成相同的操作。

 
 
 
 code> Multisample = MultisampleType.FourSamples，
 MultisampleQuality = 4 
  

（默认情况下它是，但从来没有确定）：

  device.SetRenderState（RenderState.MultisampleAntialias，true ）; 
  

当然有不同类型的样品，要找到质量/样品，请使用以下方法： p>

  new Direct3D（）。CheckDeviceMultisampleType 
  

在dx10 +设备上，当您创建交换链时，您有一个SampleDescription参数，

因此设置样本计数/质量相应

  SampleDescription samdesc = new SampleDescription（4，4）; 
  

枚举允许的samplecount / quality组合：

  int maxsamplecount = Device.MultisampleCountMaximum 
  

然后遍历样本计数使用：

  int maxquality = device.CheckMultisampleQualityLevels（format，sampleCount）; 
  

如果样本数不被支持，它将返回0。

I would like to enable antialiasing when drawing triangles like on the following picture:

I found a way to do it with XNA on this page but I want to do the same with SlimDX.

解决方案

On SlimDX/Directx9, when you create your swapchain, use this in PresentParameters:

Multisample = MultisampleType.FourSamples,
MultisampleQuality = 4

Also make sure that the multisample state is on (By default it is, but never sure):

device.SetRenderState(RenderState.MultisampleAntialias, true);

There's of course different type of samples, to find quality/samples, use the following method:

new Direct3D().CheckDeviceMultisampleType

On dx10+ device, when you create your swapchain, you have a SampleDescription parameter,

so set samples count/quality accordingly

SampleDescription samdesc = new SampleDescription(4, 4);

To enumerate allowed samplecount/quality combinations:

int maxsamplecount = Device.MultisampleCountMaximum

Then iterate for sample count using:

int maxquality = device.CheckMultisampleQualityLevels(format, sampleCount);

It will return 0 if sample count is not supported.
