    • add

      public int add(SoBufferObject inputBufferA, SbDataType typeA, SoBufferObject inputBufferB, SbDataType typeB, SoBufferObject outputBufferC, SbDataType typeC)
      Add two buffers into a third one.
      C = A + B
      Note: C can be a reference to A or B.
      Limitation: typeA and typeB must be the same as typeC.

    • computeMinMaxWithUndefinedValue

      public double[] computeMinMaxWithUndefinedValue(SoBufferObject inputBuffer, SbDataType dataType, double undefinedValue)
      Compute min max of all values contained in a buffer that are not equal to the specified undefined value.

      Parameters:
      inputBuffer - The source buffer object.

      dataType - The type of the data in the source buffer object.

      undefinedValue - ignored value

      min - max Result values

    • shift

      public int shift(SoCpuBufferObject inputBufferA, SbDataType typeA, SoCpuBufferObject outputBufferB, SbDataType typeB, float shiftFactor)
      B = A + shiftFactor
      Fast version for Cpu buffers.

    • computeMinMaxWithUndefinedValue

      public double[] computeMinMaxWithUndefinedValue(SoCpuBufferObject inputBuffer, SbDataType dataType, SbVec3i32 arrayDim, SbBox3i32 range, double undefinedValue)
      Compute min max of values contained in the specified range of the buffer that are not equal to the specified undefined value.
      Fast version for Cpu buffers.

    • computeMinMaxWithUndefinedValue

      public double[] computeMinMaxWithUndefinedValue(SoBufferObject inputBuffer, SbDataType dataType, SbVec3i32 arrayDim, SbBox3i32 range, double undefinedValue)
      Compute min max of values contained in the specified range of the buffer that are not equal to the specified undefined value.

      Assumes the buffer contains a 3D array of values. However 1D and 2D arrays can be handled as degenerate cases. For example, to use a 1D array of length N and compute over the range I to J:
      • Set arrayDim = N,1,1 (do not use 0 for any dimension)
      • Set range = I,0,0,J,1,1 (be sure min and max for each axis are not the same)

      Parameters:
      inputBuffer - The source buffer object.

      dataType - The type of the data in the source buffer object.

      arrayDim - Dimensions of the array (can be degenerate, e.g. N,1,1)

      range - Subset of the array to consider

      undefinedValue - ignored value

      min - max Result values

    • computeMinMax

      public double[] computeMinMax(SoCpuBufferObject inputBuffer, SbDataType dataType, SbVec3i32 arrayDim, SbBox3i32 range)
      Compute min max of values contained in the specified range of the buffer.
      Fast version for Cpu buffers.

    • scale

      public int scale(SoBufferObject inputBufferA, SbDataType typeA, SoBufferObject outputBufferB, SbDataType typeB, float scaleValue)
      B = A * scaleFactor
      Note: B can be a reference to A
      Limitation: typeA must be the same as typeC.
