I am not confident at all to find the connection between Monet and projection mapping. However, I am convinced that there are some similarities since these two forms of art are strongly related to light. When I read that they both ally light with canvas from an article of Projection Mapping Central, I feel like I should start with their respective connection with light and canvas. Projection mapping uses projectors(light) to display images onto a 3D shaped object(canvas), to create an optical illusion. Monet conveyed his fascination about light onto canvas directly.
“A fascination with natural light drove the technique of the impressionist painters, they explored new qualities of colour and the trail of time. Kimchi and Chips’ study of digital light discusses a new visual mechanic, their installation adding to the visual language of space and light. As the artist’s inquiry deepens, brush strokes become descriptive like code, detailing reality and allying light with canvas. “(Sodhi)
I’ve also found a site about the illustrated history of projection mapping.
