Translucent Heart

Last year I’ve started drawing mathematical functions (relevant to physics), using traditional techniques of descriptive geometry.

The very first test was an attempt to capture the three-dimensional Lissajous figure built from sin(t)/sin(2t)/sin(3t).

Here is a blog post on the history of Lissajous in a Box!

I’ve returned to it several times, and I ran out of names. I called this version Lissajous Trilogy 123 – created on technical drawing paper which looks rather “cold” and grey.

I wanted to put more emphasis on the construction of the 2D projections from “first principles” – dividing circles to “calculate trigonometric functions geometrically”.

And I wanted to document the Making Of.

So, here is the next version of Lissajous 123, now I call it Translucent Heart!

In contrast to the first tests, I’ve drawn on – thick and textured – watercolor paper. This type of paper is so not suitable for technical drawing, but I wanted to rise to the challenge!

This is the scanned drawing color-corrected and made “warmer” by reducing the color temperature. This heart should not be too cold!

Edit – voice from the future, May 2025: I changed my mind about the coolness of the heart. The print shops listed below now have the original, “cool” version!)
