Class VoxelBuffer<T extends javax.vecmath.Tuple3d>

java.lang.Object
cz.fidentis.analyst.opencl.memory.BufferGPU<FloatBuffer>
cz.fidentis.analyst.opencl.memory.WriteBufferGPU<T>
cz.fidentis.analyst.opencl.memory.impl.VoxelBuffer<T>
Type Parameters:
T - extending Tuple3d
All Implemented Interfaces:
CLResources
public class VoxelBuffer<T extends javax.vecmath.Tuple3d> extends WriteBufferGPU<T>
Buffer to hold 3D coordinates compatible with Tuple3d and it's descendants Even though 3 float values are stored, we need to allocate more space since OpenCL assumes the vector types (float3) to be aligned to match 4 * sizeof(component) boundary.
