Description
Technical field
The present invention relates to water knife parquets technical fields, specially a kind of to be discussed and curvilinear figure Boolean calculation based on computer graphic
Water knife parquets technology.
Background technique
Water knife has a wide range of application, and the market demand is big, in the design scheme of tile work customization software, has complexity more than 80%
Water knife moulding.Common tile work designer is relatively difficult using the Software Creates water cutting die type such as CAD or 3Dmax.Because learning
It is big to practise these software costs high time long difficulty, and structure is complicated for water knife, data volume is big.For the model of these Software Creates,
Also lack certain flexibility, secondary editor can not be carried out and dynamic brickwork joint is cut.Therefore, water is used for response designer
The demand of knife proposes that automatically generating water knife 3d solution to model based on CAD data determines scheme.
Summary of the invention
The purpose of the present invention is to provide a kind of water knife parquets skills discussed based on computer graphic with curvilinear figure Boolean calculation
Art should be discussed based on computer graphic and the water knife parquets technical step of curvilinear figure Boolean calculation is as follows:
S1: the material (such as cad file) of water knife figure is converted into the multi-section-line data being made of straight line and circular arc, therefore
The first step first uses the circle of curvature scheduling algorithm in calculus that will usually contain non-circular curve such as spline curve in cad file, oval
Arc etc. is converted to straight line or circular arc, and using CAD original starting point+terminal+convexity mode, the equation of straight line and circular arc is united
One, ease for use is effectively improved；
S2: finding out all intersection points of lines and lines interrupted, and lays the foundation for search closed figure；
S3: finding out all closed figures (supporting curl) using Euler's table algorithm, using the intersection point generated in S2, and it is every
A intersection point the information such as uses by which lines, we can establish Euler's relation table, is then sorted, can be looked for by angle
All closed figures out；
S4: the input customized brick information of user, water knife figure can be spliced by multiple bricks on final product and
At, therefore computer will simulate this effect, must just cut to water knife figure, be abstracted into mathematics level, then be brick
The intersection of figure and water knife figure is can be obtained with Boolean calculation as a result, being carried out using Boolean calculation to the figure that S3 is generated
It cuts；
S5: it is misplaced according to the customized bricklayer's spacing rule little progress line displacement of user, water knife figure often carries internal slope brick
Seam, but CAD producer tends not to a brickwork joint part to drawing out, and program is just needed to carry out automatic identification at this time, and
And the offset of stepping type is carried out along the normal direction of figure, to realize the automatic generation function of slope brickwork joint；
S6: curl figure is carried out trigonometric ratio using pure mathematics algorithm and submits to the rendering of video card progress effect picture, mesh
Preceding video card rendering is all based on triangular facet, does not support polygon directly, especially with curl, therefore before submitting rendering, I
Also need the figure that calculates to carry out trigonometric ratio, to realize the rendering of 3D effect figure.
Compared with prior art, as a result quasi- the beneficial effects of the present invention are: technology used in the present invention is versatile
Really, it has excellent performance, data volume is small, supports secondary editor, facilitates replacement texture and material and adjustment size, can apply to a variety of
Design scheme.
Detailed description of the invention
Fig. 1 is display renderings of the cad file of the present invention in AutoCAD；
Fig. 2 is that curl figure of the present invention carries out trigonometric ratio and submits to the effect rendering figure of video card progress.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, to this
Invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, not
For limiting the present invention.
Embodiment 1
Referring to Fig. 1, the present invention provides a kind of technical solution: one kind is discussed based on computer graphic and curvilinear figure Boolean calculation
Water knife parquets technology, should based on computer graphic discuss and curvilinear figure Boolean calculation water knife parquets technical step it is as follows:
S1: the material (such as cad file) of water knife figure is converted into the multi-section-line data being made of straight line and circular arc, therefore
The first step first uses the circle of curvature scheduling algorithm in calculus that will usually contain non-circular curve such as spline curve in cad file, oval
Arc etc. is converted to straight line or circular arc, and using CAD original starting point+terminal+convexity mode, the equation of straight line and circular arc is united
One, ease for use is effectively improved；
S2: finding out all intersection points of lines and lines interrupted, and lays the foundation for search closed figure；
S3: finding out all closed figures (supporting curl) using Euler's table algorithm, using the intersection point generated in S2, and it is every
A intersection point the information such as uses by which lines, we can establish Euler's relation table, is then sorted, can be looked for by angle
All closed figures out；
S4: the input customized brick information of user, water knife figure can be spliced by multiple bricks on final product and
At, therefore computer will simulate this effect, must just cut to water knife figure, be abstracted into mathematics level, then be brick
