I m looking for a 3D component in order to plot in 3D :  points,
lines, polygones  and surfaces (TIN Surface) do you know if there is
such component avalaible in Lazarus ?

thank you for your help

As far as I know there are no 3D plotting capabilitities for Lazarus.
TAChart is 2D only with some extensions for contour plotting (search
this forum) or color maps (http://wiki.lazarus.freepascal.org/TAChart_
Tutorial:_ColorMapSeries,_Zooming). TeeChart from Delphi is being
adapted to Lazarus (http://forum.lazarus.freepascal.org/index.php/topi
c,21690.msg127525.html#msg127525), but this is a commercial product
and requires a separate installation because of the naming conflicts
with TAChart. Alternatively, you can call gnuplot from Lazarus, grab
its output and show it within a Lazarus window. I once did this for a
complex contour plot, but for 3D you'll miss the interactivity for
selecting the viewpoint etc.

support points, lines, polygones. surfaces not support.
There's no separate component, but there is an example to use in other
program

I once wrote a raytracing component for Delphi - I've been planning to
get around to releasing it for Lazarus (open source) but haven't done
so yet. Probably do so in a few months or so...
