Constructor Details

WriteBufferGPU

public WriteBufferGPU(com.jogamp.opencl.CLContext clContext)

Creates Write Buffer in specified OpenCl Context with default element size set to 1

Parameters:

clContext - OpenCl Context

WriteBufferGPU

protected WriteBufferGPU(com.jogamp.opencl.CLContext clContext,
 int elementSize)

Creates Write Buffer in specified OpenCl Context with given element size

Parameters:

clContext - OpenCl Context

elementSize - element size

Method Details

writeToGPU

public abstract void writeToGPU()

Copies contents to GPU

putAll

public abstract void putAll(List<T> points)

Populated buffer with desired elements. Overwrites previous data and resizes itself, if needed. Is asynchronous! Make sure to call finish() method before use

getOriginalData

public abstract List<T> getOriginalData()

Gets data, that are currently copied to GPU

Returns:

data
