The document discusses using 3D projection technology to study muscle anatomy. It provides background on the history of 3D projection, from the 1950s golden era to the modern 3D theater renaissance. CT scans were used to scan beef and pork carcasses in increments, and 3D modeling software was used to isolate individual muscles as 3D objects with texture maps based on photographs. This allowed for interactive 3D visualizations and animations of muscle structures to enhance anatomical education.
