~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.
void EnableClippingPlane(int i, double *planeEquation)
Enable/Disable the specified clipping plane.
vtkSmartPointer< vtkTransform > Transform
Definition: vtkContext3D.h:181
vtkTransform * GetTransform()
Compute the current transform applied to the context.
void SetTransform(vtkTransform *transform)
Set the transform for the context, the underlying device will use the matrix of the transform.
vtkContextDevice3D * GetDevice()
Get access to the underlying 3D context.
static vtkContext3D * New()
Creates a 3D context object.
void DisableClippingPlane(int i)
Enable/Disable the specified clipping plane.
void AppendTransform(vtkTransform *transform)
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...

void DrawTriangleMesh(const float *mesh, int n, const unsigned char *colors, int nc)
Draw triangles to generate the specified mesh.
void DrawPoints(const float *points, int n, unsigned char *colors, int nc_comps)
Draw a sequence of points at the specified locations.
bool End()
Ends painting on the device, you would not usually need to call this as it should be called by the de...
