In the process of progressively-variant texture synthesis,because of the change of texture scale and direction,it needs constant resampling.In order to avoid resampling and accelerate the speed of texture synthesis,this paper adopts linear function as the transition function of texture scale,first of all,progressively-variant texture is synthesized in two-dimensional space,then uses this new texture sample and the control of vector to synthesize a progressively-variant texture on a 3D mesh.In order to prevent texture elements break apart,it adopts gray-scale image to assist synthesizing.Experimental results show that the method can produce smooth texture in most nature texture synthesis and obtain satisfactory results in synthesis efficiency.
