Calculando um Recurso com Algoritmo Diferente

To calculate a feature with different algorithm it is not necessary to re-measure the feature itself, but it is possible to re-fit using the existing points.
This functionality is typically used to build a feature from an existing point cloud or recalculate an element using a different fitting algorithm.
This statement is manually written without user interface.

$$Begin Example


MODE/PROG,MAN

F(CIR_61)=FEAT/CIRCLE,INNER,CART,0,0,0,0,0,1,250

MEAS/CIRCLE,F(CIR_61),100

ENDMES

$$FILTERING


F(CIR_62)=FEAT/CIRCLE,INNER,CART,0,0,0,0,0,1,250

GEOALG/CIRCLE,LSTSQR,FILTER,CIRCULAR,LOWPASS,6.0,GAUSS

CONST/CIRCLE,F(CIR_62),TR,FA(CIR_61)

$$getting point number for the feature


DECL/INTGR,pointNum

$$use this


pointNum=ASSIGN/PTDATA(FA(CIR_2111))

$$or this


pointNum=VALUE/FA(CIR_2111),PTDATA

$$refitting using MINCIR


GEOALG/CIRCLE,MINCIR

F(CIR_2F_MIN)=FEAT/CIRCLE,INNER,CART,0.0,0.0,16.0,0,0,1,32.0

CONST/CIRCLE,F(CIR_2F_MIN),BF,FA(CIR_2111)[1],FA(CIR_2111)[2,pointNum]

$$refitting using LEASTSQUARE


GEOALG/CIRCLE,LSTSQR

F(CIR_2F_least)=FEAT/CIRCLE,INNER,CART,0.0,0.0,16.0,0,0,1,32.0

CONST/CIRCLE,F(CIR_2F_least),BF,FA(CIR_2111)[1],FA(CIR_2111)[2,pointNum]

$$fitting plane using points from Circle


F(PLA_1)=FEAT/PLANE,CART,0.0,0.0,16.0,0,0,1

CONST/PLANE,F(PLA_1),BF,FA(CIR_2111)[1],FA(CIR_2111)[2,pointNum]
