how one can write a nice vector parser, something that does pgfvecparse{A=B-C; D=E x F;}












2















I am often use coordinates of points to draw figure in geometry. I know that, we can add, minus coordinates of points, example



begin{tikzpicture}

tkzDefPoints{0/0/C',3/0/D',1/1/B'}

coordinate (A') at ($(B')+(D')-(C')$);

 end{tikzpicture}


If I have two points A(1,2,3) and B(4,5,6), how can I define vector AB as (B)-(A)?






tikz-pgf tikzmark

  • Among the existing proposals, to my knowledge this one might be the most promising one. The open problem, though, is that the transformation is to "recorded". Some advanced transformation recording can be found here. But it seems that you are looking for something else.

If you use the coordinates only for drawing, simply define each components of points as variable and then define coordinate points using them. For example:



documentclass[margin=3.14159mm]{standalone}

usepackage{tikz,tikz-3dplot}



begin{document}

tdplotsetmaincoords{60}{125}

begin{tikzpicture}

    [scale=0.9,

    tdplot_main_coords,

    axis/.style={-latex,thick},

    vector/.style={-stealth,red,very thick},

    vector guide/.style={dashed,thick}]



%standard tikz coordinate definition using x, y, z coords

% A(2,4,3), B(3,-1,4)

defAx{2}

defAy{4}

defAz{3}

defBx{-1}

defBy{3}

defBz{4}

coordinate (O) at (0,0,0);

coordinate (A) at (Ax,Ay,Az);

coordinate (B) at (Bx,By,Bz);

%draw axes

draw[axis] (0,0,0) -- (4,0,0) node[anchor=north east]{$x$};

draw[axis] (0,0,0) -- (0,4,0) node[anchor=north west]{$y$};

draw[axis] (0,0,0) -- (0,0,5) node[anchor=south]{$z$};

%Dot at point

fill [blue] (A) circle (2pt);

fill [blue] (B) circle (2pt);

%draw a vector from O to A and O to B

draw[vector guide] (O)node[left=1mm]{} -- (A)node[above=-1mm,right]{$P_1(Ax,Ay,Az)$};

draw[vector guide] (O) -- (B)node[above=-1mm,right]{$P_2(Bx,By,Bz)$};



%draw vector D=AB

draw[vector] (A) -- (B)node[midway,above,sloped]{$mathbf{D}$};

end{tikzpicture}

end{document}
