Lake Pontchartrain And The Curvature Of The Earth

This video includes: • Photos of transmission lines over Lake Pontchartrain that show the curvature of the Earth. • Computer graphic recreations of the transmission lines. • A step by step guide to recreating the transmission lines in Blender. • An explanation of the math used. Table of contents Introduction 0:00 Introduction. 0:11 Here's what I mean. 0:21 Soundly and Walter Bislin. 0:41 Curious how to make such graphics yourself? 0:50 Preliminary concepts. Blender Tutorial 2:17 Blender time! 2:26 Initial “FlatCurve“. 3:57 “TransCurve“ (proportional editing). 5:36 Transmission tower (image texture, transparency). 7:59 Modifiers (multiple towers with a curve). 8:54 Water (curving a grid). 10:30 Camera positioning (based on Walter Bislin's page). 12:09 Colors (color processing). 12:52 Curved Earth vs. Flat Earth. 13:32 Rendering (creating ““). Conclusion 14:04 Curve compare (refraction comparison). 14:34 Conclusion (the Earth isn't flat).
