User defined function to draw additional stuff in derived classes.

Parameters:

dsl	pointer to View2DSliceList passed to the internally overloaded View2DExtension::draw() method.
dSlice	pointer to View2DSlice passed to the internally overloaded View2DExtension::draw() method.
slice	slice number passed to the internally overloaded View2DExtension::draw() method.
drawTexts	is true if text shall be drawn because it seems to fit into the default string width.
numRowComps	The number of coordinate components to be shown in one row; 0 means automatic row size, which uses root of component numbers in case of matrices.
dType	is the data type id of the voxel.
v1Buf	Pointer to the voxel data.
numDTComps	Number of components of the voxel.
font	Font to be used for text drawing.
fSize	Size of font to be used for text drawing.

		XVImageSize &	pos,
		GLfloat	rgba[4],
		float	xPos,
		float	yPos,
		View2DFont &	font,
		float	fSize
	)		`[protected]`

If drawTexts is true then draw numComps coordinate components of position pos with the color rgba at the vertical device position (xPos, yPos).

numComps must be a value from [0,...,6]. Font and font size are given by font and fSize.

float SoView2DVoxelView::_drawStringVoxelValue	(	bool	drawTexts,
		MLDataType	dType,
		MLTypeData *	vBuf1,
		int	numDTComponents,
		GLfloat	rgba[4],
		float	xPos,
		float	yPos,
		View2DFont &	font,
		float	fSize
	)		`[protected]`

Still incomplete and unused.

If drawTexts is true, the default string fits into a voxel then draw the voxel value from voxel data buffer vBuf1 (if non NULL) of type dType with numDTComponents components with the color rgba at the vertical device position (xPos, yPos) as string. Font and font size are given by font and fSize. The return value is the optimal position for drawings of the coordinate position.

		int	numDTComponents,
		GLfloat	rgba[4],
		float	xPos,
		float	yPos,
		View2DFont &	font,
		float	fSize
	)		`[protected]`

If drawTexts is true, the default string fits into a voxel then draw the voxel value from voxel data buffer vBuf1 (if non NULL) of type dType with numDTComponents components with the color rgba at the vertical device position (xPos, yPos).

Font and font size are given by font and fSize. The return value is the optimal position for drawings of the coordinate position.

void SoView2DVoxelView::_getGLColor	(	double	dblVoxVal,
		GLfloat	rgba[4]
	)		`[protected]`

Set correct color value in rgba dependent on the current settings and the voxel value dblVoxVal.

void SoView2DVoxelView::_updateLutData ( SoSFMLImage & inImg ) [protected]

Update the look up table according to the image data.

On available LUT true is returned and shift and scale can be used to transform voxel values to non clamped LutData indices. If no LUT is available then false is returned and shift and scale are left unchanged.

virtual void SoView2DVoxelView::draw	(	View2DSliceList *	dsl,
		View2DSlice *	dslice,
		int	slice
	)		`[virtual]`

Virtual method called by the SoView2D node.

It is called for each slices drawn in each viewer. dsl is the View2DSliceList, the list containing all information of all slices handled by the viewer. dslice is the slice currently drawn and slice the the number of the currently drawn slice.

Reimplemented from SoView2DExtension.

static void SoView2DVoxelView::initClass ( void ) [static]

Initialization function of this class.

It implements the registration of this class in the runtime type system of open Inventor and other user stuff e.g. activation of other Inventor classes (events, actions, elements) needed in this class.

Reimplemented from SoView2DExtension.
