Detailed Description

This class represents the MILX Qt Model/Mesh Display object using VTK.

Author: Shekhar S. Chandra, 2013

The class displays models from polygonal values using OpenGL via the VTK library. The rendering is encapsulated within a QVTK widget. It is important to generateModel(), after setting the polydata or when loading the model in a different way. This ensures everything needed to display has been updated.

Controls:

Left Mouse (hold): adjust the colour level.
Wheel: zoom the camera.
Middle Mouse (hold): translate image.
Right Mouse: context menu and zoom toggle.
Keypress f: fly to the picked point.
Keypress Shift+r: reset the camera view along the current view direction. Centers the actors and moves the camera so that all actors are visible.
Keypress r: reset the colour level to defaults.

Usage Examples: Loading a model

const QString filename = "model.vtk";
QPointer<milxQtFile> reader = new milxQtFile;
QPointer<milxQtModel> model = new milxQtModel;
bool success = reader->openModel(filename, model);
//If loaded, set attributes and generate.
if(success)
{
    model->setName(filename);
    model->setConsole(console);
    model->setDefaultView(defaultViewBox->currentIndex());
    model->generateModel();
}

Displaying a sphere

vtkSmartPointer<vtkSphereSource> sphere = vtkSmartPointer<vtkSphereSource>::New();
    sphere->SetThetaResolution(32);
    sphere->SetPhiResolution(32);
    sphere->SetRadius(10.0);
    sphere->Update();
model->setName("Sphere");
    model->SetInput(sphere->GetOutput());
    model->generateModel(0.5, 0.5, 0.5); //Grey model
    model->show();

Delaunay Graph from points

QPointer< milxQtModel > model = new milxQtModel;
    model->setName("Original Model");
    model->SetPoints(modelPoints);
    model->generateDelaunayGraph();
    model->generateLabels();
    model->show();

Point Model from points

QPointer< milxQtModel > centroidModel = new milxQtModel;
    centroidModel->SetPoints(centroidPoints);
    centroidModel->generatePointModel(0.25, 0.5, 0.5, 1.0); //!< Graph in grey

Definition at line 2945 of file milxQtModel.cpp.

◆ centroid

coordinate & milxQtModel::centroid ( )

slot

Definition at line 294 of file milxQtModel.cpp.

◆ changeOpacity

void milxQtModel::changeOpacity ( float opacity = -1 )

slot

Changes the opacity/transparency of the model. You should use the changeColour() member and set its alpha channel.

Action for this member has been removed because changeColour() provides this functionality.

Definition at line 1872 of file milxQtModel.cpp.

◆ copyToContextMenu

void milxQtModel::copyToContextMenu ( QMenu * copyMenu )

virtualslot

Copies the menu, by duplicating the entries, to the context menu. Connections are assumed to be made before hand.

This virtual implementation accounts for menus with custom connections.

Definition at line 2567 of file milxQtModel.cpp.

◆ createMenu

void milxQtModel::createMenu ( QMenu * menu )

virtualslot

Create the menu for the data in this object. Used for context menu and file menus.

Todo:: contour init doesn't work. VTK bug?

Definition at line 2476 of file milxQtModel.cpp.

◆ enableScale

void milxQtModel::enableScale	(	QString	title = `""`,
		const bool	quiet = `false`,
		double	minRange = `0.0`,
		double	maxRange = `0.0`,

	)

virtualslot

Enable scale bar display with the title provided.

Quiet Boolean is to prevent possible popups to ask user parameters.

Ask if use default scalar LUT

Definition at line 2204 of file milxQtModel.cpp.

◆ generateCappedBoundaries

void milxQtModel::generateCappedBoundaries ( )

slot

Generates capped boundaries for meshes with boundaries (such as large holes or voids).

This is useful to cap holes in an open mesh so it can be voxelised among other things.

Definition at line 962 of file milxQtModel.cpp.

◆ generateDelaunayGraph

void milxQtModel::generateDelaunayGraph	(	float	red = `defaultColour`,
		float	green = `defaultColour`,
		float	blue = `defaultColour`
	)

slot

Generates the Delaunay 3D graph for the dataset. Arguments provided are for the colours of the edges of the graph.

Warning: Modifies the PolyData pipeline so that GetOutput() will return the graph.

Generate the model

Definition at line 343 of file milxQtModel.cpp.

◆ generateDelaunayTriangulation

void milxQtModel::generateDelaunayTriangulation	(	float	red = `defaultColour`,
		float	green = `defaultColour`,
		float	blue = `defaultColour`
	)

slot

Generates the Delaunay 3D Triangulation (resulting in tetrahdral cells) for the dataset. Arguments provided are for the colours of the cells of the model.

Generate Delaunay Graph

Definition at line 380 of file milxQtModel.cpp.

◆ generateEdges

milxQtModel::generateEdges	(	float	red = `defaultColour`,
		float	green = `defaultColour`,
		float	blue = `defaultColour`
	)

inlineslot

Generates the tubes for the dataset. Arguments provided are for the colours of the tubes. Same as generateTubes, alias for convenience.

Warning: Modifies the PolyData pipeline so that GetOutput() will return the graph.

Definition at line 800 of file milxQtModel.h.

◆ generateHedgehog

void milxQtModel::generateHedgehog	(	double	newScale = `0.0`,

		float	blue = `defaultColour`
	)

slot

Generates a hedgehog model, i.e. lines at each point for the dataset whose lengths are given by the vector magnitudes. Arguments provided are for the scale and colours of the lines.

Warning: Modifies the PolyData pipeline so that GetOutput() will return the vectors.

You should have set the points and vectors (using SetPoints() and SetVectors()) before call this member.

Definition at line 724 of file milxQtModel.cpp.

◆ generateNormals
