在 Delphi 下使用 DirectSound (18): 3D 特效

减小字体 增大字体 作者:佚名  来源:转载  发布时间:2011-02-16 15:48:14

DirectSound 3D 特效相关接口: IDirectSound3DBuffer8、IDirectSound3DListener8.

IDirectSound3DBuffer8 是声源, 它可以有一个或多个; IDirectSound3DListener8 是听者, 它只能有一个.

IDirectSound3DBuffer8 通过 QueryInterface() 从次缓冲获取, 要求该次缓冲建立时必须指定 DSBCAPS_CTRL3D;
IDirectSound3DListener8 通过 QueryInterface() 从主缓冲区获取, 该主缓冲区建立时也必须指定 DSBCAPS_CTRL3D.

"声源" 和 "听者" 可以交互变换, 也可独立变换; 只变换 "听者" 时, 提供声音的缓冲区建立时也应该指定 DSBCAPS_CTRL3D.
IDirectSound3DBuffer8 其实只负责 3D 效果变换, 真正提供声音和播放控制的还是它之前的 IDirectSound3DBuffer 或 IDirectSound3DBuffer8.



IDirectSound3DBuffer8 相关方法:


{3D 音效处理模式}
GetMode()、SetMode()
  DS3DMODE_NORMAL       = $00000000; //普通
  DS3DMODE_HEADRELATIVE = $00000001; //声源的参数是相对于听者的
  DS3DMODE_DISABLE      = $00000002; //禁用 3D 特效

{最大、最小距离}
GetMaxDistance()、SetMaxDistance()
GetMinDistance()、SetMinDistance()

{位置、速度、方向}
GetPosition()、SetPosition()
GetVelocity()、SetVelocity()
GetConeOrientation()、SetConeOrientation()

{声源椎参数}
GetConeAngles()、SetConeAngles()
GetConeOutsideVolume()、SetConeOutsideVolume()

{一起获取或设置参数}
GetAllParameters()、SetAllParameters()


IDirectSound3DListener8 相关方法:


{位置、速度、方向}
GetPosition()、SetPosition()
GetVelocity()、SetVelocity()
GetOrientation()、SetOrientation()

{距离因子、多普勒因子、滚降因子}
GetDistanceFactor()、SetDistanceFactor() 
GetDopplerFactor()、SetDopplerFactor()
GetRolloffFactor()、SetRolloffFactor()

{一起获取或设置参数}
GetAllParameters()、SetAllParameters()

{延迟设置}
CommitDeferredSettings() //在使用系列 Set... 方法时, 如果指定了 DS3D_DEFERRED 参数, 则需用该方法提交参数设置;
                         //和 DS3D_DEFERRED = 1 对应的是 DS3D_IMMEDIATE = 0, 表示立即生效; 使用延迟设置更节省资源.
