Detailed Description

Code for managing data that is to be rendered with column integration.

Uses disply lists. Vertex buffer objects may be faster.

#define ROOT_3 1.73205f

#define ROOT_3_ON_2 0.866025404f

data_column_int_t* data_column_int_create	(	unsigned int	n,
		float *	x,
		float *	y,
		float *	z,
		float *	h,
		float *	weight,
		float *	data,
		float	data_min,
		float	data_max
	)

Creates a new data object.

Parameters:

[in]	n	The number of points.
[in]	x	The x coordinantes of the points.
[in]	y	The y coordinantes of the points.
[in]	z	The z coordinantes of the points.
[in]	h	The smoothing length of the particles.
[in]	weight	The weight of each particle.
[in]	data	The value of the quantity being integrated at each particle.
[in]	data_min	The value of data that will be assigned to the lowest colour in the table.
[in]	data_max	The value of data that will be assigned to the highest colour in the table.

void data_column_int_destroy ( data_column_int_t * ds )

Frees the memory associated with the given data_column_int_t.

Parameters:

[in] ds the data to be destroyed.

void data_column_int_render ( data_column_int_t * ds )

Renders the given particles.
