Detailed Description

Class for drawing 3D primitives to a graphical context.

This defines the interface for drawing onto a 3D context. The context must be set up with a vtkContextDevice3D derived class that provides the functions to facilitate the low level calls to the context. Currently only an OpenGL based device is provided.

Member Function Documentation

static int vtkContext3D::IsTypeOf ( const char * name ) [static]

Return 1 if this class type 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 vtkObject.

virtual int vtkContext3D::IsA ( const char * name ) [virtual]

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 vtkObject.

static vtkContext3D* vtkContext3D::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkObject.

virtual vtkObjectBase* vtkContext3D::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkObject.

vtkContext3D* vtkContext3D::NewInstance ( ) const

Reimplemented from vtkObject.

virtual void vtkContext3D::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 vtkObject.

static vtkContext3D* vtkContext3D::New ( ) [static]

Creates a 3D context object.

Reimplemented from vtkObject.

bool vtkContext3D::Begin ( vtkContextDevice3D * device )

Begin painting on a vtkContextDevice3D, no painting can occur before this call has been made. Only one painter is allowed at a time on any given paint device. Returns true if successful, otherwise false.

vtkContextDevice3D* vtkContext3D::GetDevice ( )

Get access to the underlying 3D context.

bool vtkContext3D::End ( )

Ends painting on the device, you would not usually need to call this as it should be called by the destructor. Returns true if the painter is no longer active, otherwise false.

void vtkContext3D::DrawLine	(	const vtkVector3f &	start,
		const vtkVector3f &	end
	)

Draw a line between the specified points.

void vtkContext3D::DrawPoly	(	const float *	points,
		int	n
	)

Draw a poly line between the specified points.

void vtkContext3D::DrawPoint ( const vtkVector3f & point )

Draw a point at the point in 3D space.

void vtkContext3D::DrawPoints	(	const float *	points,
		int	n
	)

Draw a sequence of points at the specified locations.

void vtkContext3D::DrawPoints	(	const float *	points,
		int	n,
		unsigned char *	colors,
		int	nc_comps
	)

Draw a sequence of points at the specified locations. The points will be colored by the colors array, which must have nc_comps components (defining a single color).

void vtkContext3D::DrawTriangleMesh	(	const float *	mesh,
		int	n,
		const unsigned char *	colors,
		int	nc
	)

Draw triangles to generate the specified mesh.

void vtkContext3D::ApplyPen ( vtkPen * pen )

Apply the supplied pen which controls the outlines of shapes, as well as lines, points and related primitives. This makes a deep copy of the vtkPen object in the vtkContext2D, it does not hold a pointer to the supplied object.

void vtkContext3D::ApplyBrush ( vtkBrush * brush )

Apply the supplied brush which controls the outlines of shapes, as well as lines, points and related primitives. This makes a deep copy of the vtkBrush object in the vtkContext2D, it does not hold a pointer to the supplied object.

void vtkContext3D::SetTransform ( vtkTransform * transform )

Set the transform for the context, the underlying device will use the matrix of the transform. Note, this is set immediately, later changes to the matrix will have no effect until it is set again.

vtkTransform* vtkContext3D::GetTransform ( )

Compute the current transform applied to the context.

void vtkContext3D::AppendTransform ( vtkTransform * transform )

Append the transform for the context, the underlying device will use the matrix of the transform. Note, this is set immediately, later changes to the matrix will have no effect until it is set again. The matrix of the transform will multiply the current context transform.

void vtkContext3D::PushMatrix ( )

Push/pop the transformation matrix for the painter (sets the underlying matrix for the device when available).

void vtkContext3D::PopMatrix ( )

Push/pop the transformation matrix for the painter (sets the underlying matrix for the device when available).

void vtkContext3D::EnableClippingPlane	(	int	i,
		double *	planeEquation
	)

Enable/Disable the specified clipping plane. i is the index of the clipping plane being enabled or disabled (0 - 5). planeEquation points to the four coefficients of the equation for the clipping plane: Ax + By + Cz + D = 0. This is the equation format expected by glClipPlane.

void vtkContext3D::DisableClippingPlane ( int i )

Enable/Disable the specified clipping plane. i is the index of the clipping plane being enabled or disabled (0 - 5). planeEquation points to the four coefficients of the equation for the clipping plane: Ax + By + Cz + D = 0. This is the equation format expected by glClipPlane.
