    • calculateBBox

      static com.jogamp.opencl.CLBuffer<FloatBuffer> calculateBBox(com.jogamp.opencl.CLContext clContext, com.jogamp.opencl.CLCommandQueue queue, WriteBufferGPU<javax.vecmath.Point3d> vertexBuffer)
      Calculates Bounding Box of buffer of vertices.
      Parameters:
      vertexBuffer - Buffer of vertices. It is not modified during the process
      Returns:
      Buffer of 8 floats containing the bounding box

    • getLargestInteger

      static int getLargestInteger(com.jogamp.opencl.CLContext clContext, com.jogamp.opencl.CLCommandQueue queue, com.jogamp.opencl.CLBuffer<IntBuffer> intBuffer, int count)
      Reduces the buffer to find the largest integer. Wipes the buffer in the process
      Parameters:
      intBuffer - Buffer of integers
      count - Size of the buffer
      Returns:
      largest integer
