Class MeshTriangleBuffer

java.lang.Object

cz.fidentis.analyst.opencl.memory.BufferGPU<FloatBuffer>

cz.fidentis.analyst.opencl.memory.WriteBufferGPU<MeshTriangle>

cz.fidentis.analyst.opencl.memory.impl.MeshTriangleBuffer

All Implemented Interfaces:

CLResources

public class MeshTriangleBuffer
extends WriteBufferGPU<MeshTriangle>

Class providing readable conversion of MeshTriangle data to reside in OpenCL buffers Each triangle is represented by 3 points and 3 vectors. Each point and vector are copied to separate buffers, so the whole triangle is stored under one index. For ex. To get 5th triangle on GPU --> we need to collect the components under index 5

Method Details

release

public void release()

Description copied from interface: CLResources

Explicitly releases GPU resources held by this object

writeToGPU

public void writeToGPU()

Description copied from class: WriteBufferGPU

Copies contents to GPU

Specified by:

writeToGPU in class WriteBufferGPU<MeshTriangle>

get

public com.jogamp.opencl.CLBuffer<FloatBuffer> get()

Description copied from class: BufferGPU

Get underlying CLBuffer

Specified by:

get in class BufferGPU<FloatBuffer>

Returns:

Specified by:

getOriginalData in class WriteBufferGPU<MeshTriangle>

Returns:

data

allocateBuffer

protected void allocateBuffer(int elementCount)

Description copied from class: BufferGPU

Allocate the buffer to fit the elements

Specified by:

allocateBuffer in class BufferGPU<FloatBuffer>

Parameters:

elementCount - desired size of the buffer

resizeSubBuffer

protected void resizeSubBuffer(int elementCount)

Description copied from class: BufferGPU

Creating new SubBuffer of the main buffer to operate with smaller amount of memory

Specified by:

resizeSubBuffer in class BufferGPU<FloatBuffer>

Parameters:

elementCount - desired size of the buffer
