Alongside the royal

Fournier subsequently corrected these failings, using a larger point with greater compatibility with existing forms of type.[4]

Truchet points
used in their construction.

The commission also designed the

vector representations of letter shapes, tabulations of font metrics, and oblique font faces.[4]

In 1699, at the second public meeting of the French Academy, Truchet spoke on the motion of falling bodies,[5] and nearly 20 years later he was one of several scientists to confirm Newton's model of the separation of white light into colors.[6]

As a hydraulics expert, he designed most of the French canals.[4]

Inspired by decorations he had seen on the canals, Truchet studied decorative patterns on ceramic tiles.

Truchet tiling.[8]

He is also known for his expertise as a watchmaker,[9] and for his inventions concerning sundials, weapons and tools for transplanting large trees within the Versailles gardens.[citation needed]
