Voxler Features

Isosurface

A Voxler isosurface extends the concept of the contour line (a line of constant data value in two dimensions) to display a surface of constant data value in three dimensions. Combine multiple isosurfaces colour-coded by data value to show discrete values through a 3D grid.

Contours

Contours display lines of constant data value along a plane. For a 3D grid, the plane can be oriented at any angle. Image shows contours intersecting a semi-transparent isosurface.

Stream Lines

Stream lines are used to display the path of particles through a velocity field, the distribution of velocities of a medium in 3D space. Different colours indicate the magnitude of the velocities.

Scatter Plot

A scatter plot displays symbols at the XYZ location specified in the data file. If the data file has a value at each data point you can specify different colours for different data values.

Annotation and Text

Use annotation and text to add textual information to a plot. Annotation is used to display textual information positioned at the specified screen coordinates and anchored at data XYZ coordinates.

Bounding Box

The bounding box is a part of a plot that shows the limits of the XYZ data ranges. It is a good way to show the ranges when the settings produce a graphic that does not cover the entire range, as for some isosurfaces. It also provides a good reference system to orient the graphic output.

More Computation Options

Voxler provides a number of computational options including filters for eliminating duplicate data points, removing data points based on the X, Y, Z, or data values, calculating normal, distance-weighted, Gaussian averaging, data metrics, and image processing. Other computational modules calculate gradient, grid math with up to three 3D grid files, merge up to five 3D grid files, resample, subset, and transform operations.

Rendered Volume

A rendered volume assigns a colour and transparency value to every element in the 3D grid. Add a ClipPlane to display a slice through the volume at any angle.

 

Height Field

A height field displays data values as colours for a 2D grid, a 2D orthogonal slice of a uniform 3D grid, or along a 2D curvilinear lattice. The data magnitude is also depicted by the amount of displacement above or below the slice. The displacement is perpendicular to the plane or curvilinear lattice and is adjusted by the scale factor.

Vector Plot

A vector plot displays lines or arrows indicating the direction and magnitude indicated by the components of a 3D grid or point data set. The magnitude of the vectors is shown by length and colour.

Clip Plane

Add a clip plane to any graphic to remove the portion on one side of the clip plane. Add multiple clip planes at different angles to display the area of interest without obstruction.

Axes

Add axes to a plot to display the XYZ coordinate ranges. Axes are colour-coded to identify each direction. Change the plane of the axis labels the axis and rotate the labels around a point centered at each tick mark.

3D Gridding

Voxler can take scattered XYZC data (XYZ coordinates with a data value C) and produce a uniform 3D grid using Inverse Distance, and Local Polynomial gridding methods. It also can calculate a large number of Data Metrics within the specified search radii, including minimum, maximum, median, mean, quartiles, standard deviation, variance, count, density, and distance to nearest and farthest point.

Adding Light to a Scene

Lighting options include ambient light, camera headlight, directional, point, and spot lights with settings for colour, intensity and direction. Use the graphical Dragger tool to aim and position directional, point, and spot lights.

User Interface

Voxler implements a modern user interface with dockable and floating windows and toolbars. The Network window graphically displays the connections between data and output, and Properties window lists the settings specified for each module.

Printing

Voxler features an improved print dialog with a print preview that is especially helpful when printing graphics that cover several pages. Don't guess at how many pages a large plot will need! View the page requirements in the dialog preview. Print everything, or just the current view. Control image quality, add antialiasing to smooth a print out, and print the background colour as needed.

Properties Window

The Properties window lists the settings for the selected module with edit boxes, sliders, and buttons for changing the settings.

Network Window

The Voxler Network window graphically displays the modules (input data, computational, graphic output, info) and their connections. LED lights display green, yellow, or red to indicate the status of the module. Click on a module to select it and to display its settings in the Properties window.

Module Library

The Module Library shows a list of available modules and commands in an accessible format. The window is docked by default, and drag the title bar to float the window.

Reposition Toolbars and Windows

Toolbars and windows are docked to the Voxler application window by default, or drag the title bar to a new location to float the windows in any position.
