Detailed Description

A class for describing a 3D axis-aligned region in user space.

Author: Alan Norton

Version: $Revision$

Date: $Date$ The RegionParams class controls the extents of a 3D box of data for visualization. The DVR, Isosurface and Flow renderers use only the data specified by the current RegionParams. There is a global RegionParams, that is shared by all windows whose region is set to "global". There is also a local RegionParams for each window, that users can select whenever there are multiple windows. When local settings are used, they only affect one currently active visualizer. The RegionParams class also has several methods that are useful in setting up data requests from the DataMgr.

Constructor & Destructor Documentation

VAPoR::RegionParams::RegionParams ( int winnum )

Parameters

[in] int winnum The window number, or -1 for a global RegionParams

VAPoR::RegionParams::~RegionParams ( )

Destructor.

Member Function Documentation

static float VAPoR::RegionParams::calcCurrentValue	(	const string &	varname,
		const double	point[3],
		int	numRefinements,
		int	lod,
		size_t	timeStep
	)

static

Evaluate a variable at a point, as requested by a RenderParams

Parameters

[in]	string	varname requested variable name (2d or 3d)
[in]	double	point[3] User coordinates of requested value
[in]	int	numRefinements Refinement level of requested data
[in]	int	lod Compression level of requested data
[in]	int	timeStep Time step of data

float VAPoR::RegionParams::fullRegionMBs ( int refLevel )

Calculate the full size of the region in megabytes, at specified refinement level.

Parameters

[in] int reflevel Refinement level of data, use -1 for max refinement.

Return values

float size in megabytes.

int VAPoR::RegionParams::getAvailableVoxelCoords	(	int	reflevel,
		int	lod,
		size_t	min_dim[3],
		size_t	max_dim[3],
		size_t	timestep,
		const int *	sesVarNums,
		int	numVars,
		double *	regMin = `0`,
		double *	regMax = `0`
	)

Method to obtain voxel and user coordinates of the available data in the region. The region extents may be shrunk so as to include only the portion of the region for which the specified variables are available. If the requested refinement level is not available, and the user allows use of lowered accuracy, then returns the highest refinement level that is available. Returns -1 if required data is unavailable. Optionally provides user data extents.

Return values

int	Available refinenement level, or -1 if no data available

Parameters

[in]	int	reflevel Refinement level of requested coordinates
[in]	int	lod LOD of data
[out]	size_t	min_dim[3] Minimum voxel coordinates of available region
[out]	size_t	max_dim[3] Maximum voxel coordinates of available region
[in]	size_t	timestep Time step at which the data is being requested.
[in]	int*	sesVarNums An array of integer session 3D variable nums for requested variables
[in]	int	numVars Number of variables, i.e. size of sesVarnums
[out]	double*	regMin Minimum user coordinates, if this pointer is non-null
[out]	double*	regMax Maximum user coordinates, if this pointer is non-null

void VAPoR::RegionParams::getRegionVoxelCoords	(	int	reflevel,
		int	lod,
		size_t	min_dim[3],
		size_t	max_dim[3],
		int	timestep
	)

Method to obtain voxel coords of a region, but doesn't verify the existence of data in the region.

Parameters

[in]	int	reflevel Refinement level of requested coordinates
[in]	int	lod LOD of data for requested coordinates, needed for ELEVATION
[out]	size_t	min_dim[3] Minimum voxel coordinates of region
[out]	size_t	max_dim[3] Maximum voxel coordinates of region
[in]	int	timestep Time step at which the coordinates are being requested.

static int VAPoR::RegionParams::PrepareCoordsForRetrieval	(	int	numxforms,
		int	lod,
		size_t	timestep,
		const vector< string > &	varnames,
		double *	regMin,
		double *	regMax,
		size_t	min_dim[3],
		size_t	max_dim[3]
	)

static

Static method to prepare for retrieval of data arrays from DataMgr.

Parameters

[in]	int	numxforms Requested refinement level of data
[in]	int	lod Requested LOD of data
[in]	size_t	timestep Time for which data is requested.
[in]	vector<string>&	varnames Vector of 2D or 3D variable names being requested
[in,out]	double*	regMin Minimum user coordinate extents requested (in) and actual available (out)
[in,out]	double*	regMax Maximum user coordinate extents requested (in) and actual available (out)
[out]	size_t	min_dim[3] Minimum voxel coordinates of available region
[out]	size_t	max_dim[3] Maximum voxel coordinates of available region

Return values

int	Actual refinement level available or -1 if not all variables available.
