Embodiment Construction

[0046] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047] The present invention achieves the purpose of realizing real-time 3D rendering of interactive ink painting style on low-end graphics cards by rendering the model to the Backbuffer (back-end cache). At the same time, ink-style animation is realized by performing ink-style rendering on animation frames.

[0048] In the present invention, two key frames of the animation are saved as models, namely Model0 and Model1, which have the same number of vertices and the same order of vertices, but the positions of the vertices are slightly different. By preprocessing the two models, the edge lists edg...

Abstract

The invention suits for the fields of computer mapping, it provides an interactive ink and wash real-time 3D rendering and realizing cartoon method, said method includes steps as following: 1.1 common grid models is prophase preprocessed to generate a list of adjacent surface normal line information; 1.2 searching the top of configuration border, and judging the top of configuration border with chasing top of double normal line; 1.3 model is rendered to the Backbuffer of the display card to reject the top of visible object line; 1.4 the top of visible object line which is after the rejection is connected to strokes, the strokes are warped with painter pen touch; 1.5 the inner model is colored. The invention can realize the ink and wash style in low side display card, and integrate the computer artwork with ink and wash effect to game graph engine to generate needed cartoon effect.

Description

technical field [0001] The invention belongs to the field of computer graphics, and in particular relates to a method for realizing real-time 3D rendering of interactive ink wash style. Background technique [0002] In recent years, the development of computer graphics (Computer Graphics) field can be divided into two research directions: one is the research on the real physical light and shadow model, which is the closest to the real world effect seen by human eyes, which is called Photorealistic Rendering technology, we can see its vigorous development in computer games and movie special effects; the other is to study the effect of works created by painters who outline their imaginary creative space and abstract artistic conception with brushes , this research direction is called non-photorealistic rendering (Non-Photorealipstic Rendering) technology. [0003] As far as the research field of non-photorealistic drawing is concerned, the more developed and mature ones are p...
