This is a quick-and-dirty 3D vector field visualization, for viewing output of a NWP model such as NAM or WRF (file format may vary).

Requirements:

• Processing 2.x (www.processing.com)
• Java 7 JDK (www.java.com)
• Hardware-accelerated OpenGL (most modern computers)

UI:

• mouse drag: rotate X (tilt) and Z (lazy susan)
• +/- keys (actually + and = / - and _) select altitude

Expects file ./wind.csv to be of the form:
