If you're familiar with our 3D data visualization software, Voxler, you're probably aware that it is a 1:1:1 modeller. This means that each dimension (X, Y, and Z) and each dataset in the project is treated as if it uses the same units. If your X and Y data use a different unit than the Z data, or if your datasets use different units, then this could result in an undesirable display. In the past, you would need to use Transform modules to correct the positioning or reproject the data in a different program, such as Surfer mapping software. Don't worry about manually transforming data or switching between programs any longer! With Voxler 4's new worksheet feature, you can quickly and easily convert your point data to use a different unit by reprojecting the data.
In this example, most of my data is in feet, but I have XY point locations measured in meters. Let's take a look at a quick and easy way to remedy this with Voxler's new worksheet!
Project created using measurements in feet, before adding point data.
The image above shows my project, which contains a HeightField module with a vector overlay (also new in Voxler 4) and a Contours module. The DXF file and both 2D lattices use feet for the X, Y, and Z values. The HeightField shows the topography of the state of Tennessee, and the contours show the average daily temperature for the month of October. I also have a data file containing points for city locations, but the point locations are defined by UTM meters, rather than State Plane feet, which is used by the rest of my data. The image below shows what happens when I import the point data in meters into the existing project and display it with a ScatterPlot module.

As you can see, all of the points are jumbled up in the upper left corner and are very far away from the other data. To rectify this, I can reproject my point data in Voxler's worksheet so the points locate in the correct position, using the steps below. This workflow also takes advantage of Voxler's new hot editing feature!
The image below shows the points reprojected to use the same units as the rest of the project. The points locate in their correct positions, relative to the rest of the data.

These powerful new features can streamline your workflow and minimize the number of applications necessary to complete your project. Reprojecting your point data is only one of many great features available with Voxler's new worksheet support!
