3D图像的卡通式渲染(国外英文资料) Cartoon rendering of 3D images Wu wenjie From GameRes Abstract: We give an algorithm for generating 3D images that resemble traditional cartoonish style (static or active images). This 3D rendering technique will be implemented: -- draw the outline and edges of the object in black, Uniformly, color the surface of the edge line, Render shadow parts (including shadow and cast shadows on the back of the object) according to the location of the light source. Key words: Computer graphics do not render the cartoon rendering cartoon A list, This paper proposes an algorithm for cartoonish 3D images generated by computer algorithms. The sort of trying to generate as much as possible with the traditional similar to the real world (also become reality) of different image rendering algorithm, the comical image rendering using a more formalized with suggestive way (which can be understood as a more abstract). For example, characters and objects depicted by cartoons are characterized by contours and more uniform coloring. (1) typical characteristics There are many variations and layers in the painting. The dimensions of the outline can be altered, and the colored areas may include gloss or a special atmosphere created by the effect of light and shadow. Here were not going to try and reproduce all the effects. Were only concerned with how to get a cartoonish image, including how to achieve a fixed size and uniform coloring. In addition, we add three special effects: the use of a material instead of a uniform coloring area, and the effect of a specific high light effect on an object, as well as the effect of the shadow. Here are a few things to add: (1) the material is not required, but the introduction of it can provide a shortcut for the performance of the rich picture, for example on a surface can be repeated using the same texture to reduce unnecessary workload. Reflected light can be made of material (flat, luminous, metal...) Provide a visual feedback. The
