DESCRIPTION

SUMMARY

vtkRayCaster()
Constructor for vtkRayCaster

~vtkRayCaster()
Destructor for vtkRayCaster

void SetImageScale( int level, float scale )
Set the scale factor for a given level. This is used during multi- resolution interactive rendering

float GetImageScale( int level )
Get the scale factor for a given level. This is used during multi- resolution interactive rendering

void AutomaticScaleAdjustmentOn( void )
Turn the automatic scale adjustment on

void AutomaticScaleAdjustmentOff( void )
Turn the automatic scale adjustment off

void GetViewRaysSize(int size[2])
Get the size in pixels of the view rays for the selected scale indexl

float GetViewportScaleFactor( vtkRenderer *ren )
This method returns the scale that should be applied to the viewport for geometric rendering, and for the image in volume rendering. It is either explicitly set (if AutomaticScaleAdjustment is off) or is adjusted automatically to get the desired frame rate.

Note: IMPORTANT!!!! This should only be called once per render!!!

int Render(vtkRenderer *ren)
Main routine to do the volume rendering.
