This is possible with Bootstrap, but requires some configuration ...
See this example in Bootply: http://bootply.com/94444
You must adjust the position of the slides using CSS and jQuery ..
.carousel-inner .active.left { left: -33%; }
.carousel-inner .next { left: 33%; }
.carousel-inner .prev { left: -33%; }
. , carousel-inner..
.carousel-inner:before {
position:absolute;
top:0;
bottom: 0;
right: 82%;
left: 0;
content:"";
display:block;
background-color: #fff;
z-index: 2;
}
.carousel-inner:after {
position:absolute;
top:0;
bottom:0;
right: 0;
left: 82%;
content:"";
display:block;
background-color:#fff;
z-index: 2;
}
