Member Function Documentation

static int vtkOpenGLContextDevice3D::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 vtkContextDevice3D.

virtual int vtkOpenGLContextDevice3D::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 vtkContextDevice3D.

static vtkOpenGLContextDevice3D* vtkOpenGLContextDevice3D::SafeDownCast

(

vtkObjectBase *

o

)

[static]

Reimplemented from vtkContextDevice3D.

virtual vtkObjectBase* vtkOpenGLContextDevice3D::NewInstanceInternal

(

)

const [protected, virtual]

Reimplemented from vtkContextDevice3D.

vtkOpenGLContextDevice3D* vtkOpenGLContextDevice3D::NewInstance

(

)

const

Reimplemented from vtkContextDevice3D.

void vtkOpenGLContextDevice3D::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 vtkContextDevice3D.

static vtkOpenGLContextDevice3D* vtkOpenGLContextDevice3D::New

(

)

[static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

void vtkOpenGLContextDevice3D::DrawPoly	(	const float *	verts,
		int	n,
		const unsigned char *	colors,
		int	nc
	)		[virtual]

Draw a polyline between the specified points.

Implements vtkContextDevice3D.

void vtkOpenGLContextDevice3D::DrawPoints	(	const float *	verts,
		int	n,
		const unsigned char *	colors,
		int	nc
	)		[virtual]

Draw points at the vertex positions specified.

Implements vtkContextDevice3D.

void vtkOpenGLContextDevice3D::DrawTriangleMesh	(	const float *	mesh,
		int	n,
		const unsigned char *	colors,
		int	nc
	)		[virtual]

Draw triangles to generate the specified mesh.

Implements vtkContextDevice3D.

void vtkOpenGLContextDevice3D::ApplyPen

(

vtkPen *

pen

)

[virtual]

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.

Implements vtkContextDevice3D.

void vtkOpenGLContextDevice3D::ApplyBrush

(

vtkBrush *

brush

)

[virtual]

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.

Implements vtkContextDevice3D.

void vtkOpenGLContextDevice3D::SetMatrix

(

vtkMatrix4x4 *

m

)

[virtual]

Set the model view matrix for the display

Implements vtkContextDevice3D.

void vtkOpenGLContextDevice3D::GetMatrix

(

vtkMatrix4x4 *

m

)

[virtual]

Set the model view matrix for the display

Implements vtkContextDevice3D.

void vtkOpenGLContextDevice3D::MultiplyMatrix

(

vtkMatrix4x4 *

m

)

[virtual]

Multiply the current model view matrix by the supplied one

Implements vtkContextDevice3D.

void vtkOpenGLContextDevice3D::PushMatrix

(

)

[virtual]

Push the current matrix onto the stack.

Implements vtkContextDevice3D.

void vtkOpenGLContextDevice3D::PopMatrix

(

)

[virtual]

Pop the current matrix off of the stack.

Implements vtkContextDevice3D.

void vtkOpenGLContextDevice3D::SetClipping

(

const vtkRecti &

rect

)

[virtual]

Supply a float array of length 4 with x1, y1, width, height specifying clipping region for the device in pixels.

Implements vtkContextDevice3D.

void vtkOpenGLContextDevice3D::EnableClipping

(

bool

enable

)

[virtual]

Enable or disable the clipping of the scene.

Implements vtkContextDevice3D.

void vtkOpenGLContextDevice3D::EnableClippingPlane	(	int	i,
		double *	planeEquation
	)		[virtual]

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.

Implements vtkContextDevice3D.

void vtkOpenGLContextDevice3D::DisableClippingPlane

(

int

i

)

[virtual]

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.

Implements vtkContextDevice3D.

virtual void vtkOpenGLContextDevice3D::EnableDepthBuffer

(

)

[protected, virtual]

Begin drawing, turn on the depth buffer.

virtual void vtkOpenGLContextDevice3D::DisableDepthBuffer

(

)

[protected, virtual]

End drawing, turn off the depth buffer.
