Non-contact three-dimensional graphical representation of measured data

Degrees, filled with realistic color and other aspects of the attempt, and have achieved good results. (1) to accelerate the speed of the painter algorithm blanking strategy of observation by the two adjacent cross-section data drawn in the \It is enclosed by a number of quadrilateral formed. Blanking in accordance with the painter algorithm strategy,[link widoczny dla zalogowanych], just follow the \However, when stacked up layer by layer zone,[link widoczny dla zalogowanych], the zone of the second half (that is,[link widoczny dla zalogowanych], the figure part a-c-e) in turn is covered (see 6), previously invisible in the field out and do this part of the polygon work is equivalent to waste a body of data based on the characteristics and the correlation between adjacent faults,[link widoczny dla zalogowanych], the rings of polygons do not have to \painted the first visible to the last quadrilateral quadrilateral can be seen. This will enable the hidden processing to shorten the time to ask nearly half. Algorithm to achieve this strategy are as follows: Supplement to Demin, etc.; non-contact three-dimensional measurement data, graphical representation 39a. I +1 fault and fault calculation in coordinates of each point as the see; b. T find the fault, as see in the direction of the largest point and the coordinates of the minimum point of their serial number is entered, the; c. On the fault. And faults. +1 Rearrange the data, to form \Will depend on the coordinate transformation to screen coordinates, see after the drawing and filling quadrilateral, when the ring belt after the last visible quadrilateral, t +1, turn. C language implementation of this strategy process is as follows: where Xfrm see the purpose of calculating the coordinates as a subroutine, PloyDrawFill drawing and filling quadrilateral subroutine. voidDrawFunction () {inti,】, k,[link widoczny dla zalogowanych], n, 1, Imin, Imax, xmin, xmax, irain, imax ~ float ★ xl. ★ yl; floatxt, yt, zt, wt; for (i 一 0; i (xmax)) {xmax = pvtl [13.x: Imax-1:} 40 Tianjin Institute of Light Industry in December 1993 Jff (Imax> l0) fimax ~ Imax ~ imin = hnin: fot (n-imax; n <= 35; n + +) {Tamp [0) [n - imax3. x = pvtl [n]. x; Tamp [0] [n - imax]. y ~ pvtl [n].
