Method Details

createComputeQueue

public ComputeQueueResult createComputeQueue()

Create a queue for executing compute shaders.

Returns:

a new result object

createComputeSystem

public static ComputeSystemResult createComputeSystem()

Create a compute system that uses a GPU.

Returns:

a new result object

createComputeSystemCpu

public static ComputeSystemResult createComputeSystemCpu()

Create a compute system that doesn't use any GPU.

Returns:

a new result object

getRtti

public Rtti getRtti()

Access the run-time type information of the current compute system. (native function: GetRTTI)

Returns:

a new JVM object with the pre-existing native object assigned

hairRegisterShaders

public static void hairRegisterShaders(ComputeSystem system)

If the argument is a ComputeSystemCPU, register its hair shaders.

Parameters:

system - the system to modify (not null)

setShaderLoader

public void setShaderLoader(Loader loader)

Replace the system's shader loader. (native member: mShaderLoader)

Parameters:

loader - the loader to use (not null)

getRefCount

public int getRefCount()

Count the active references to the native ComputeSystem. The system is unaffected.

Specified by:

getRefCount in interface RefTarget

Returns:

the count (≥0)

setEmbedded

public void setEmbedded()

Specified by:

setEmbedded in interface RefTarget

toRef

public ComputeSystemRef toRef()

Create a counted reference to the native ComputeSystem.

Specified by:

toRef in interface RefTarget

Returns:

a new JVM object with a new native object assigned
