Function Documentation

template<typename image_type >

OpenTissue::texture::texture2D_pointer OpenTissue::volume_rendering::compute_1D_preintegration_color_table

(

image_type const &

color_table

)

Compute Preintegrated Color Table.

Parameters:

color_table

The color table that should be integrated.

Returns:

A pointer to a preintegrated color table texture object.

template<typename histogram_type , typename image_type >

void OpenTissue::volume_rendering::compute_histogram_color_table	(	unsigned int	entries,
		histogram_type const &	histogram,
		image_type &	color_table
	)

Histogram Based Color Table. This function analyses a histogram and assign colors to a color table based on the features detected in the histogram.

template<typename image_type >

void OpenTissue::volume_rendering::compute_linear_color_table	(	unsigned int	entries,
		image_type &	color_table,
		bool	reverse = false,
		bool	transparency = false
	)

Linear Color Mapping.

Parameters:

	entries	The number of entries on the color table.
	color_table	Upon return this argument holds the newly generated color table as an 1 row image with entries pixels in it.
	reverse	If set to true (default false) low image intensities are mapped to high colors.
	transparency	If set to trur the alpha channel in the color table is also lineary scaled. Default is false.

template<typename image_type >

void OpenTissue::volume_rendering::compute_noise_color_table	(	unsigned int	entries,
		image_type &	color_table
	)

Smooth Noise Color Mapping.

Parameters:

	entries	The number of entries on the color table.
	color_table	Upon return this argument holds the newly generated color table as an 1 row image with entries pixels in it.
