Abstract

The invention discloses a method for generating a normal map, and the method comprises the steps: loading a 3D model, and enabling the texture map coordinates of the 3D model to be unfolded and placedon a UV plane; determining the normal color corresponding to each vertex and each edge according to the tangent normal of each vertex and each edge of the 3D model; filling grids on the UV plane according to the vertexes and the edges; and generating a normal map according to the grid and the normal color. According to the method, the normal map can be automatically generated directly according to the 3D model, so that the high-modulus manufacturing and baking time is greatly saved, and the rendering efficiency of the object is greatly improved.

Description

Technical field[0001]The present invention relates to the technical field of image processing, in particular to a method and device for generating a normal map.Background technique[0002]With the continuous development of computer graphics, images, and video technologies, people's pursuit of image fidelity is getting higher and higher. Image processing technology can be used to describe more and more real images, in which the normal map method can improve the fidelity of the description of three-dimensional images. The normal is a kind of bump. The normal map can make the surface of the three-dimensional object have the rendering effect of light and shadow distribution, which can greatly reduce the number of faces and calculation content required for object rendering, so as to optimize the rendering effect of animation and games.[0003]In next-generation games, objects often need to be soft-edged, so that the game can render more refined effects with fewer model faces. Such asfigure 1...
