[Gmsh-announce] New Gmsh release: 1.62

[Christophe Geuzaine]

New in 1.62: new option to draw color gradients in the background;
enhanced perspective projection mode; new "lasso" selection mode (same
as "lasso" zoom, but in selection mode); new "invert selection" button
in the visibility browser; new snapping grid when adding points in the
GUI; nicer normal smoothing; new extrude syntax (old syntax still
available, but deprecated); various small bug fixes and enhancements.

A quick note on the new extrusion syntax:

The new syntax conforms with the syntax of all other transformations
(Translate, Symmetry, etc.). So instead of

Extrude Line {22, {0,0,1}};
Extrude Surface {6, {0,0,1},{0,1,0},Pi/2}{ Layers{10,1}; Recombine; };
...

now we have

Extrude {0,0,1} { Line{22}; }
Extrude {{0,0,1},{0,1,0},Pi/2}{ Surface{6}; Layers{10,1}; Recombine; }
...

Note the absence of a final semicolon. The return values are thus
available using "ret[] = Extrude{0,0,1}{ Surface{6}; };" and the old
"double semi-colon bug" is gone. Another advantage of the new syntax is
that several entities can be extruded at the same time, e.g.:

Extrude{Pi,0,0}{ Surface{6,8,22:45}; Point{4,3}; }
