r - RGL: multiple polygon3d that can go through -


i developping shiny application , looking way force polygons drawing. using rgl 3d scatterplot , want able draw polygons between points share same information.

my problem that, apparently, if polygon3d (p1) exists, new polygon3d (p2) can't drawn if p2 go through p1. can disable fill parameter, of course, , have segments, in thin lines, each polygons, want make polygons more highlighted, filling them if possible. how can fill or highlight polygons?

edit:

here 2 screenshots.

1) try in polygon3d option fill = f. here, can see segments delimitate polygons.

2) try in polygon3d option fill = t. here, can see few polygons. lost polygons generate followed error:

warning in max(-coeffs[dn, 2]/(coeffs[dn, 1] - coeffs[dn, 2])) :   aucun argument pour max ; -inf est renvoyé warning in max(-coeffs[up, 1]/(coeffs[up, 2] - coeffs[up, 1])) :   aucun argument pour max ; -inf est renvoyé warning in max(-coeffs[up, 1]/(coeffs[up, 2] - coeffs[up, 1])) :   aucun argument pour max ; -inf est renvoyé error in processoutside(i) : cannot triangulate polygon
