vtkVolumeRayCastIsosurfaceFunction - An isosurface ray caster for volumes

Description:

vtkVolumeRayCastIsosurfaceFunction is a volume ray cast function that intersects a ray with an analytic isosurface in a scalar field. The color and shading parameters are defined in the vtkVolumeProperty of the vtkVolume, as well as the interpolation type to use when locating the surface (either a nearest neighbor approach or a trilinear interpolation approach)

Detailed Method Descriptions:

Construct a new vtkVolumeRayCastIsosurfaceFunction

static vtkVolumeRayCastIsosurfaceFunction *New ()

Given a ray type, cast a ray through the scalar data starting at ray_position and taking num_steps of ray_increment size. Return the final compositing value in pixel_value where pixel_value[0] = red, pixel_value[1] = green, pixel_value[2] = blue, pixel_value[3] = alpha pixel_value[4] = depth, and pixel_value[5] = number of steps

void CastARay (int ,void * ,float ,float ,int ,float )

Get the scalar value below which all scalar values have 0 opacity

float GetZeroOpacityThreshold (vtkVolume *)

Set/Get the value of IsoValue.
