Detailed Description

A direction encoder based on spherical coordinates.

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkDirectionEncoder.

◆ NewInstanceInternal()

◆ PrintSelf()

void vtkSphericalDirectionEncoder::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkDirectionEncoder.

◆ New()

static vtkSphericalDirectionEncoder* vtkSphericalDirectionEncoder::New ( )

static

Construct the object. Initialize the index table which will be used to map the normal into a patch on the recursively subdivided sphere.

◆ GetEncodedDirection()

int vtkSphericalDirectionEncoder::GetEncodedDirection ( float n[3] )

virtual

Given a normal vector n, return the encoded direction

Implements vtkDirectionEncoder.

◆ GetDecodedGradient()

float* vtkSphericalDirectionEncoder::GetDecodedGradient ( int value )

virtual

/ Given an encoded value, return a pointer to the normal vector

Implements vtkDirectionEncoder.

◆ GetNumberOfEncodedDirections()

int vtkSphericalDirectionEncoder::GetNumberOfEncodedDirections ( void )

inlinevirtual

Return the number of encoded directions

Implements vtkDirectionEncoder.

Definition at line 49 of file vtkSphericalDirectionEncoder.h.

◆ GetDecodedGradientTable()

float* vtkSphericalDirectionEncoder::GetDecodedGradientTable ( void )

inlinevirtual

Get the decoded gradient table. There are this->GetNumberOfEncodedDirections() entries in the table, each containing a normal (direction) vector. This is a flat structure - 3 times the number of directions floats in an array.

Implements vtkDirectionEncoder.

Definition at line 56 of file vtkSphericalDirectionEncoder.h.
