函數(shù) |
描述 |
|
DXUTPause |
將框架的內(nèi)部計數(shù)器和（或）渲染過程設為暫停狀態(tài) |
|
DXUTRenderingPaused |
檢查當前設備的渲染狀態(tài)是否處在暫停狀態(tài) |
|
DXUTIsTimePaused |

DXUTPause
Sets the paused state of DXUT internal timer and/or rendering process.
VOID DXUTPause(
BOOL bPauseTime ,
BOOL bPauseRendering
) ;
Parameters
- bPauseTime
- [in] If TRUE, DXUT internal timer is paused. If FALSE, the timer is resumed from a paused state. See Remarks.
- bPauseRendering
- [in] If TRUE, DXUT will not call the LPDXUTCALLBACKD3D10FRAMERENDER callback function; DXUT will continue to call the LPDXUTCALLBACKFRAMEMOVE callback function. If FALSE, rendering will resume from a paused state. See Remarks.
Return Values
No return value.
Remarks
The timer controls the fTime and fElapsedTime parameters passed to the LPDXUTCALLBACKFRAMEMOVE or render callback functions.
When time is paused, fTime will remain unchanged and fElapsedTime will be 0.0f. The LPDXUTCALLBACKFRAMEMOVE and the render callback functions will still be called. This allows a camera to still move while time is paused.
When rendering is paused, the render callback function and the Direct3D Present method will not be called, and DXUT will periodically yield time to other processes by calling Sleep.
DXUTIsRenderingPaused
Indicates whether rendering has been paused in DXUT.
BOOL DXUTIsRenderingPaused() ;
Parameters
None.
Return Values
TRUE if rendering has been paused in DXUT.
DXUTIsTimePaused
Indicates whether time has been paused in DXUT.
BOOL DXUTIsTimePaused() ;
Parameters
None.
Return Values
TRUE if time has been paused in DXUT.
