Ancient artists used a technique called stippling – in which pictures are created by painting or carving a series of tiny dots – to produce drawings on cave walls and utensils thousands of years ago.
This image of a human cranium was created with a new kind of computer-imaging software that uses the ancient technique of stippling to convert complex medical data into 3-D images that can be quickly viewed by medical professionals. Data from CT scans were converted into dots to create the stippled image. Cave dwellers and artisans used stippling thousands of years ago to create figures by painting or carving a series of tiny dots. More recently, 19th century Parisian artist Georges Seurat used the method, also called pointillism, to draw colorful, intricately detailed works. Because dots are the most simple visual element in a picture, they also are ideal for computer visualizations. (Purdue University School of Electrical and Computer Engineering)

Now engineers at Purdue University have created a new kind of computer-imaging software that uses stippling to quickly produce complex pictures of internal organs and other renderings. The method is 10 times faster than some conventional methods and could provide a tool for medical professionals to quickly preview images in real time as a patient is being examined with imaging technologies such as CT scans and magnetic resonance imaging (MRI).
In stippling, also known as pointillism, the artist creates numerous dots with paint, ink or pencil to produce gradations of light and shade, forming an image. Georges Seurat, a 19th century Parisian artist, used the same technique to draw colorful, intricately detailed works.
