PROBLEM TO BE SOLVED: To provide a three-dimensional CG image editing device, for efficiently setting a lighting condition. SOLUTION: The three-dimensional CG image editing method includes: a projection area setting step of drawing, in response to input of a projection area instruction, a projection area on a three-dimensional CG image of three-dimensional model data viewed from a point of view set in a three-dimensional space; a light source setting step of drawing, for all pixels constituting the projection area drawn on the three-dimensional CG image, a visual straight line from the point of view to pass through each pixel and calculating an incident light line regularly incident on the visual straight line at an intersection crossing the three-dimensional model to set a light source on the incident light line; and a rendering step of using the set light source to render a three-dimensional CG image with light projected to the three-dimensional model.
