  1. Like mightier folk before me, I have been trying to figure out how to put text into the 3-D Babylon world. Not unlike the thread at bottom. It would be best it was dynamic, not a fixed pre-setup, yeah? One can do this in SVG with a little help from OpenType.js . . . and Text-To-SVG, which uses it. If you look at a couple of glyphs (https://opentype.js.org/glyph-inspector.html) you may quickly conclude that one could put them in a BABYLON Path2, then into a polygon and we are off and running. Yay! One small wrinkle: The OpenType output makes extensive use of quadratic curves. (http://blogs.sitepointstatic.com/examples/tech/svg-curves/quadratic-curve.html) No such thing in a Path2; just an arc. When the OpenType is translated into SVG (using text-to-svg), the path looks a little like this: "M1.66 19.58L1.66 19.58L1.66 2.99L1.66 2.99Q1.66 1.80 2.50 0.99L2.50 0.99L2.50 0.99Q3.35 0.18 4.54 0.18L4.54 0.18L4.54 0.18Q5.72 0.18 6.53 0.99L6.53 0.99L6.53 0.99Q7.34 1.80 7.34 2.99L7.34 2.99L7.34 18.90L7.34 18.90Q7.34 20.16 8.44 21.02L8.44 21.02L8.44 21.02Q9.54 21.89 10.76 21.89L10.76 21.89L10.76 21.89Q12.02 21.89 13.00 21.04L13.00 21.04L13.00 21.04Q13.97 20.20 14.00 19.01L14.00 19.01L14.00 2.99L14.00 2.99Q14.00 1.80 14.83 0.99L14.83 0.99L14.83 0.99Q15.66 0.18 16.85 0.18L16.85 0.18L16.85 0.18Q18.04 0.18 18.86 0.99L18.86 0.99L18.86 0.99Q19.69 1.80 19.69 2.99L19.69 2.99L19.69 19.58L19.69 19.58Q19.69 23.00 17.01 25.27L17.01 25.27L17.01 25.27Q14.33 27.54 10.76 27.54L10.76 27.54L10.76 27.54Q7.16 27.54 4.41 25.25L4.41 25.25L4.41 25.25Q1.66 22.97 1.66 19.58Z" That's a letter. (Not sure which letter; that doesn't matter.) I could write a wee utility to turn this path into a BABYLON polygon except for those quadratic curves in the path. If there was a Path2.addCurveTo method, then there would be no technical barrier. At this point, I have stalled out a little. I would be pleased to write an add-on for BABYLON but I am trying to decide what definition would be most useful. I think emulating Text-To-SVG functionality might be the way to go. This was brought to you by the Letter G.
