Detailed Description

Type conversion functions for CUDA buffers

This module provides data type conversions, like bytes to floats...

NOTE: The classes in this module do not exist in Open Inventor 10.0 and later.

Examples:

SoCudaConversion::SoCudaConversion ( )

Constructor.

int SoCudaConversion::convert	(	SoCudaBufferObject *	sourceBufferObject,
		const SbDataType	src_type,
		SoCudaBufferObject *	targetBufferObject,
		const SbDataType	dst_type,
		const size_t	size
	)

Convert the data in a buffer object from one data type to another one.

CUDA input version.

virtual int SoCudaConversion::convert	(	SoBufferObject *	sourceBufferObject,
		const SbDataType	src_type,
		SoBufferObject *	targetBufferObject,
		const SbDataType	dst_type,
		const size_t	size
	)			`[virtual]`

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.

Reimplemented from SoConversion.

int SoCudaConversion::convertFloatToRGBA	(	SoCudaBufferObject *	sourceBufferObject,
		SoCudaBufferObject *	targetBufferObject,
		const size_t	size,
		const float	dataMin,
		const float	dataMax
	)

Convert FLOAT data stored in a buffer to (grayscale) RGBA data.

Cuda input version.

virtual int SoCudaConversion::convertFloatToRGBA	(	SoBufferObject *	sourceBufferObject,
		SoBufferObject *	targetBufferObject,
		const size_t	size,
		const float	dataMin,
		const float	dataMax
	)			`[virtual]`

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.
