Research And Realization Of Simplification Generating Technology Based On Discrete Points

This paper has carried on deep research to the generating course of realistic image simplification and has analyzed its shortcoming and insufficient. Then a kind of new method of simplification on the basis of discrete points and dot domain is proposed. The thought of this method is very novel and it can avoid a large amount of operation of calculating points of intersect. Because of its simple data construction, the operation of a large amount of reconstruction topological structure . And because of the simple procedure of modeling, this method is suitable for showing the cartoon. Work on this text make include: Simplify and lose shape technology,etc. instead on the basis of the a bit more dispersed curved surfaces, all make the good result in a lot of different scenes. In these parts make a large amount of work, propose the new algorithm this text, And has been verified in practice.This text was carried on on the foundation based on a bit more dispersed modelling , each that this method has changed traditionally is stored, But at scene curved surfaces have try to achieve dispersed to store a bit. We cut open the curved surface to divide into several small polygons by way of even parameter ization at first, Then reach each little polygon projection to get the corresponding projection area on the screen, And then to each one and alike plain some space curved surface one that had corresponding to find it in the projection area, Arrange into several arrays according to these some dispersed projection on the screen at last, Ones of the each a piece of arrays watch the Z values of coordinate arrange in an order from childhood according to them. The first color value clicked or luminance value in it was each array that showed on the curved surface finally, Very natural realization disappear latent, but other to use for and calculate shade, transparent,etc. a bit.The curved surface is simplified: The basic thought lies in dispersed curved surface or output result of the modelling software after rebuilding from the three-dimension get rid of the redundant information and degree of accuracy of guaranteeing model , What the real-time quality, data of inning order to benefit the graphical display are stored is economic with the fast native of data transmission. The method that this literary grace fetches is to fetch and sample in the distance regularly . Sample distance is 4 namely at every eaches original to sample and collect one a piece of values of arrayses a bit. But during the practical application, the surface camber of the figure is different. So on the relatively smooth curved surface, it is law vectorial curveds surface with relatively small angle that are become that is had, Sample and click the enough expression. But if at geometry detail a abundant one increase and sample in order to preventing figure from lose shape one soon on the surface. At the method who literary grace draw if every eaches collect law vectorial angle becomes that order that come out exceed one worth often. These points add the ones of one. Then pass and belong to judging . We can solicit and add the corresponding inspiration information according to the outside thing of the object for this reason. In order to sampling in the distance of suitable size that is chosen. Sample the algorithm on the basis of law vectorial dispersed self-adaptations a bitsLose shape instead : Because figure in succession, and ones that we adopt are as follows. It loses shape to be through raising and sample frequency or to regard picture element as one a piece of limited areases instead, But not click and deal with and solve and draw the distortion problem in the course one.A question of producing the picture is along the losing shape of outline line. Losing shape in order to lighten this kind, we have carried on algorithm of losing shape insteads of a piece of border. When and z value difference of picture element is remarkable around for the z value of picture element, will be measured out as the picture element on the line of outline, And set the...
