检验Device能力
过程:(伪代码).仅列出了主要使用
,或内主要参数. foreach(adapterinManager.Adapters)
{
//获取显示模式和适配器格式
foreach(allowedFormats)//适配器格式见后
{
foereach(DisplayModeinadapter.SupportedDisplayModes[allowedFormats[i]])
如果有效,添加到DisplayModeList,adapterFormatList;
}
foreach(DeviceType)//设备类型见后
{
Caps=Manager.GetDeviceCaps(adapter,DeviceType);
//检查设备类型
foreach(adapterFormat)//由上得到
适配器格式 foreach(backbufferFormat)//后缓存Cache格式见后
foreach(windowed)//window模式或全屏模式
{
Manager.CheckDeviceType(adapter,DeviceType,adapter,backbufferFormat,windowed);
//是否支持像素着色后混合?也就是alpha测试,像素雾,渲染目标混合,颜色写等
支持 Manager.ChechDeviceFormat(adapter,DeviceType,adapter,Usage.QueryPostPixelShaderBlending,Resource.Textures,backbufferFormat
}
//检查深度模板格式 [Page]
foreach(depthStencil//possibleDepthStencilFormat)//深度和模板格式见后
{
Manager.CheckDeviceFormat(adapter,DeviceType,adapterFormat,Usage.DepthStencil,ResourceType.Surface,depthStencil);
Manager.CheckDepthStencilMatch(adapter,DeviceType,adapter,backbufferFormat,depthStencil);
}
//检查multisample
类型 foreach(multiSampleType//possibleMultiSampleType)//multisample类型见后
{
Manager.CheckDeviceMultiSampleType(adapter,DeviceType,backBufferFormat,windowed,multiSampleType);
}
//检查深度模板格式和multisample类型是否冲突
foreach(depthStencil//possibleDepthStencilFormat)//由上得到
深度模板格式 foreach(multiSampleType//possibleMultiSampleType)//multisample类型
{
Manager.CheckDeviceMultiSampleType(adapter,DeviceType,depthStencil,windowed,multiSampleType);
}
//检查渲染间隔 [Page]
foreach(presentInterval)//渲染间隔值见后
{
(isWindowed)不支持PresentInterval.Two,Three,Four. (PresentInterval.Default||Device.Caps.PresentationIntervals&presentInterval)支持; }
}
}
