convertFloatToRGBA
public int convertFloatToRGBA(SoCpuBufferObject sourceBufferObject, SoCpuBufferObject targetBufferObject, long size, float dataMin, float dataMax)
Convert FLOAT data stored in a buffer to RGBA data. Fast implementation for CPU buffers.
-
convertFloatToRGBA
public int convertFloatToRGBA(SoBufferObject sourceBufferObject, SoBufferObject targetBufferObject, long size, float dataMin, float dataMax)
Convert FLOAT data stored in a buffer to (grayscale) RGBA data.- The source and the target buffers can be the same.
- The algorithm maps float values between dataMin and dataMax to the range 0..255.
- The resulting values are clamped to 0..255.
- Parameters:
sourceBufferObject
- The source buffer object containing the FLOAT data.targetBufferObject
- The target buffer object.size
- The number of FLOAT values to convert.dataMin
- The minimum value for the greyscale conversion.dataMax
- The maximum value for the greyscale conversion.- Returns:
- Returns 0 if there were no errors during the process. Returns 1 if one or more buffers don't have the correct size.
-
convert
public int convert(SoCpuBufferObject sourceBufferObject, SbDataType src_type, SoCpuBufferObject targetBufferObject, SbDataType dst_type, long size)
Convert the data in a buffer object from one data type to another one.
Fast implementation for CPU buffers.
-
convert
public int convert(SoBufferObject sourceBufferObject, SbDataType src_type, SoBufferObject targetBufferObject, SbDataType dst_type, long size)
Convert the data in a buffer object from one data type to another one.
Notes: The destination buffer and the source buffers can be same.
Limitations: This function only supports FLOAT and UNSIGNED_BYTE for dst_type.
- Parameters:
sourceBufferObject
- The source buffer object.src_type
- The type of the data in the source buffer object.targetBufferObject
- The destination buffer object.dst_type
- The destination type.size
- The number of elements in the source buffer object to convert.- Returns:
- Returns 0 if there were no errors during the process. Returns 1 if one or more buffers don't have the correct size.
