Class SoCpuBufferUniform

All Implemented Interfaces:
SafeDisposable

public class SoCpuBufferUniform extends SoCpuBufferObject
LDM buffer object optimized for uniform (single value) tile data. This type of buffer efficiently represents a uniform tile, in other words a tile in which every value is the same. The buffer can be used like any other buffer, but uses very little memory when its contents are not actually being accessed.

    • map

      public void map(SoGLBufferObject targetBufferObject, SoBufferObject.AccessModes accessMode, long startPosition, long mappingSize)
      Map the current buffer object into the specified GL buffer object.

      See the general map method for more information.

    • map

      public void map(SoCpuBufferObject targetBufferObject, SoBufferObject.AccessModes accessMode, long startPosition, long mappingSize)
      Map the current buffer object into the specified CPU buffer object.

      See the general map method for more information.

    • getValue

      public double getValue()
      Get the value of the uniform tile.
    • setRealSize

      public void setRealSize(long realSize)
      Set the real size of the buffer object in bytes.
    • getRealSize

      public long getRealSize()
      Returns the real size of the buffer in bytes.
    • getType

      public SbDataType getType()
      Get the type of the value of the uniform tile.
    • getMinMax

      public double[] getMinMax()
      Get the min and max values in the buffer, if they are known.
      Returns false if these values have not been set or computed. Returns true if values are available.

      Parameters:
      min - user variable to store min value

      max - user variable to store max value
    • unmap

      public void unmap(SoCpuBufferObject bufferObject)
      Unmap the specified CPU buffer object
      It is defined just to speed up the call when the type of the object is known.
      Remove the specified bufferObject from the list of buffers which map the current buffer.

      See the general unmap function for more information.

    • unmap

      public void unmap(SoGLBufferObject bufferObject)
      Unmap the specified GL buffer object
      It is defined just to speed up the call when the type of the object is known.
      If the access mode supports writing the specified buffer is sync'd with the buffer.

      See the general unmap function for more information.

      Parameters:
      bufferObject - Buffer to be unmapped.
    • setValue

      public void setValue(double value, SbDataType dataType)
      Set the value and data type for this uniform buffer.
