Matlab figures: print Vector graphic cointaining image data

Dear all, i need to figure out how to create vectorgraphics in a meaningfol way. for example, this snippet produces a nice vector graphic with a 50x50 image:

function VectorGraphicTest
    fig=figure(1);clf;
    set(fig,...
        'renderer','painter')
    k=50;
    data =rand(k);
    range=1:k;
    [xx,yy]=ndgrid(range,range);
    zz=zeros(size(xx));
    surf(xx,yy,zz,data,'EdgeColor','none')
    print('TestVecIMage.pdf','-dpdf')
    open('TestVecIMage.pdf')
end

however, tfor larger images (640*1024) the 'painters' flag takes minues to print the figure, and Adobe has a hard time showing the images.

now my question is, how can i still print a decen quality vector graph that looks like

but is a vector plot (the pdf print of that last figure is a bitmap) This is for volume data vizualisation, generated with the following code:

function VectorGraphicTest
    fig=figure(1);clf;
    set(fig,...
        'renderer','opengl')
    k=1000;
    data =rand(k);
    range=1:k;
    [xx,yy]=ndgrid(range,range);
    zz=zeros(size(xx));1
    surf(xx,yy,zz,data,'EdgeColor','none')
    hold on
    surf(xx,yy,zz+1000,data,'EdgeColor','none')
    surf(xx,yy,zz+500,data,'EdgeColor','none')
    print('TestVecIMage.pdf','-dpdf')
    print('TestVecIMage.png','-dpng')
    open('TestVecIMage.pdf')
end

Processing 650 thousand patch objects needs time. Creating and interpreting vector graphics with a huge number of elements stored in a PDF is expensive such that buying a faster computer is the best option to accelerate it.

There are better formats for such data. I'd expect e.g. a SVG to be faster, see e.g. https://www.mathworks.com/matlabcentral/fileexchange/7401-scalable-vector-graphics--svg--export-of-figures or print -dsvg in modern Matlab versions. But it is not clear if you do need a PDF file.
