Description
Technical field
The present invention relates to a kind of graphical design field, deformed more particularly, to a kind of graphical design based on 3D softwares
Method.
Background technology
With the progress in epoch, the purchase crowd of case and bag gradually has the requirement of differentiation to case and bag, original average side
The case and bag product of side is difficult to obtain their favor, can only be absorbed in price competition, profit margin drops.
Therefore some case and bag manufacturer provides the case and bag of space pattern, and some patterns are devised on case and bag, and
According to by these pattern stereoscopics, but it is due to that mapping all carries out, now, image and case and bag mould in the planes
This part of type can there is a situation where inconsistent, can seriously cause the poor quality of product.
And when this inconsistent, experienced designer can only be passed through at present and draw satisfactory picture
To overcome, one is that cost can be caused high, and the design charges of veteran designer has with the design charges of conventional design teacher
There is a great gap, and design modification repeatedly also brings along great workload and extra-pay；Two are
Efficiency is low, in face of new model element, for example, original designer has been grasped for face's (eyes and nose)
Image Adjusting design tactics, but when there is new model element, such as palm, the experience of designer is also almost
Zero.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind is soft based on 3D
The graphical design deformation method of part.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of graphical design deformation method based on 3D softwares, including step：
1) virtual three-dimensional model of case and bag three-dimensional model is set up in 3D softwares, and obtains the virtual three-dimensional model
Grid chart per one side, and each grid is encoded；
2) irregular block on virtual three-dimensional model is determined, and extracts the coding of all irregular block correspondence grids；
3) case and bag image is imported, and the coding of grid is corresponded to case and bag figure according to the grid chart and irregular block
As carrying out drawing high deformation.
The step 3) specifically include step：
31) import case and bag image, and case and bag image and case and bag three-dimensional model corresponding relation, set up case and bag image
With the corresponding relation of virtual three-dimensional model, and the element conduct in the case and bag image corresponding to all irregular blocks is extracted
Deform element；
32) stretching change is carried out to all deformation elements according to the coding of grid chart and all irregular blocks correspondence grid
Shape；
33) by the case and bag image projection after stretcher strain into the grid chart.
The step 32) in each deformation element draw-texture process specifically include step：
321) size of deformation element is determined；
322) the corresponding irregular block of deformation element is determined, and is loaded into the coding of irregular block correspondence grid；
323) according to the size of the coding of the grid of loading and grid, the size of irregular block is calculated；
324) according to the size of irregular block and the Size calculation drawing deformation of modifying element, and to deformation element
It is draw textured.
The step 33) specifically include step：
331) the deformation element after stretcher strain is projected into the grid chart, and be modified；
332) remainder of case and bag image is projected into the grid chart, wherein, the case and bag image it is surplus
Remaining part is divided into the part in addition to element is deformed in case and bag image.
The irregular block is specially：The block raised or sunken relative to whole case and bag face.
The size of all grids is identical in the grid chart.
Compared with prior art, the present invention has advantages below：
1) it is designed based on 3D softwares, the success of design variations is ensure that when actual drawing goes out sample,
It need not repeat to test, reduce and waste, success rate is close to 100%.
2) the corresponding pictorial element of irregular block is targetedly deformed using grid chart, deformation can be improved
Precision and accuracy rate, the designer lacked experience even for irregular shape shell graphical design can also be real
Existing planar design is deformed to the conversion of three dimensional designs.
3) due to being encoded to all grids, accurate deformation can be accomplished, the success of deformation is substantially increased
Rate, shortens design man-hour.
4) size of size and corresponding deformation element of the stretcher strain based on irregular block is carried out, and is reduced and is done over again
Rate.
