This command is a Tcl wrapper of some OpenGL functions. It allows to use OpenGL commands directly from GiD-Tcl.
For example, for C/C++ is used:
...
- doscrzoffset <boolean> Special trick to avoid the lines on surfaces hidden by the surfaces.
- pgfont pgffont pushfont|popfont|print|dimensions|foreground|background
Command for PG fonts
- pgfont pgffont pushfont <font_type>
Push sets the current OpenGL font and add to stack.
font types: DefaultFont, AxisFont, LegendFont, LabelFont, GraphFont, AsianFont, TkdrawoglFont, PmFont - pgfont pgffont popfont
Restores the previous font and remove from stack. Commands push/pop must be called always paired
- pgfont pgffont print <text>
To draw a <text> in the current 3D location (set by GiD_OpenGL draw -rasterpos [list $x $y $z]). It is similar to GiD_OpenGL drawtext
- pgfont pgffont dimensions <text>
Return the width of <text> and <height> of current font. Sizes in pixels, but result are float, not int as could be expected.
