[Scilab-users] trouble with vectorial export

[Calixte Denizet]

Hi Adrien,

About vectorial export in 5.3: we used a thirdparty library (gl2ps) 
which used an opengl trick to make the export, so huge graphics could to 
lead to crash.
In 5.4, we completely rewrite the vectorial exporter (we removed gl2ps) 
and huge graphics are now ok (the export can be long in 3D since there 
is a lot of computation (intersecting triangle, intersecting segments, 
...)).
For the 2D, I found an easy solution to take into account the style 
(I'll implement it asap), but in 3D it is more complex, since a polyline 
can be behind and in front of a triangle the polyline need to be broken 
(even if it doens't meet the triangle). Actually a polyline is broken 
into segments and all the segments are drawn in a particular order 
(according to their positions) and the line style is broken... An idea, 
in 3D, could be to break the polyline into the segments corresponding to 
the line style, but the polyline entity is lost.
I hope to be able to propose a solution for 2D in the next week and for 
3D, I don't know.
