~vtkContext3D() override
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
bool Begin(vtkContextDevice3D *device)
Begin painting on a vtkContextDevice3D, no painting can occur before this call has been made.
void DrawLine(const vtkVector3f &start, const vtkVector3f &end)
Draw a line between the specified points.
void DrawPoly(const float *points, int n)
Draw a poly line between the specified points.
vtkContextDevice3D * GetDevice()
Get access to the underlying 3D context.
vtkTransform * GetTransform()
Compute the current transform applied to the context.
void EnableClippingPlane(int i, double *planeEquation)
Enable/Disable the specified clipping plane.
vtkSmartPointer< vtkTransform > Transform
Definition: vtkContext3D.h:181
void SetTransform(vtkTransform *transform)
Set the transform for the context, the underlying device will use the matrix of the transform.
void DisableClippingPlane(int i)

Append the transform for the context, the underlying device will use the matrix of the transform.
void DrawPoints(const float *points, int n)
Draw a sequence of points at the specified locations.
void PopMatrix()
Push/pop the transformation matrix for the painter (sets the underlying matrix for the device when av...
