|
* \brief This class controls the SPU usage of SPURS
|
||
|
|
*
|
||
|
|
* There are three ways to initialize SPU usage.
|
||
|
|
*
|
||
|
|
* The first way is to initialize SPURS yourself, and to pass in a pointer to
|
||
|
|
* SPURS as well as priorities for the use of the SPUs, using initWithSpurs.
|
||
|
|
* This is good if you intend to use SPURS elsewhere in your code, the management
|
||
|
|
* can be shared across all processes.
|
||
|
|
*
|
||
|
|
* The second way is to control the number of SPUs used by SPURS with
|
||
|
|
* initWithSpuCount. Software will create its own instance of SPURS when it needs
|
||
|
|
* it using that maximum number of SPUs.
|
||
|
|
*
|
||
|
|
* If you do neither of the two, Software will create its own instance of SPURS when
|
||
|
|
* it needs it using CELL_SPURS_DEFAULT_SPU_COUNT SPUs.
|
||
|
|
*
|
||
|
|
* terminate() can be used to either detatch from an existing SPURS or to
|
||
|
|
* terminate the Software-created SPURS. Note that this will only work if all collision
|
||
|
|
* scenes have been destroyed, otherwise SPURS would still be needed.
|
||
|
|
*
|
||
|
|
* Creating a new scene will cause SPURS to re-initialize.
|
||
|
|
*
|
||
|
|
* isSpursInitialized can be used to query whether software is currently using SPURS.
