VR_Data_Visualization

VR_Data_Visualization is a tool for loading files with 3D data (with X, Y, and Z columns) and viewing them in VR.

Installation

The following details how to install the VR Data Visualization package.

1. Clone the VR_data_visualization repository to your local machine

2. Open this project using Unity version 2020

Quickstart

In the player script, go to the Update() method and then to the if statement that checks if the “Q” key has been pressed. There, you fill find the line:

string[] input_files = new[] { "" }

Inside the quotation marks, you can put the location of the file you want to load. Make sure the first line of the file starts with “# X Y Z”. It must include “X Y Z” in the first row.

Next, go to Unity and click the LoadDataPrefab. Here, you can set graph options for loading your data. For data sets under 20,000 points, I would recommend having the OBJECT_SCALE set to 0.3 and GRAPH_SCALE at 100.

Load large data sets

Loading data sets over 100,000 points is not recommended using this application, but it is possible.

To do so, use the following formula:

((X / (0.03182)) / (4/3 * pi)) ^ (1/3)

Where X is the number of data points to determine the ideal graph scale to visualize that data. Then, go to the LoadDataPrefab and set the GRAPH_SCALE to equal the value of the result times 2.
