3D Extruded Buildings & Urban Footprints
Real-world 3D building extrusions with dynamic sunlight shadows, terrain DEM elevations, and pitch/bearing camera controls.
carouseluiHorizontal or vertical scroller with previous/next controls. Built on embla-carousel-react (the official shadcn carousel pattern) and wired through a React context. Drop in images, cards, or any custom slide content.

/**
* Carousel
*
* A flexible carousel / slider for cycling through content, built on
* embla-carousel-react (the official shadcn carousel pattern). All parts are
* consolidated into this single file and wired through a React context that
* holds the embla api.
*
* Tailwind class strings are kept 1:1 with the Vue registry's carousel so the
* two frameworks render identically.
*
* @example - Basic carousel with images
* <Carousel>
* <CarouselContent>
* {images.map((img) => (
* <CarouselItem key={img.id}>
* <img src={img.src} alt={img.alt} className="w-full h-full object-cover" />
* </CarouselItem>
* ))}
* </CarouselContent>
* </Carousel>
*
* @example - Carousel with navigation controls
* <Carousel opts={{ loop: true }}>
* <CarouselContent>
* {slides.map((slide) => (
* <CarouselItem key={slide.id}>
* <SlideContent content={slide} />
* </CarouselItem>
* ))}
* </CarouselContent>
* <CarouselPrevious />
* <CarouselNext />
* </Carousel>
*
* @example - Vertical carousel
* <Carousel orientation="vertical">
* <CarouselContent>
* {items.map((item) => (
* <CarouselItem key={item}>{item}</CarouselItem>
* ))}
* </CarouselContent>
* </Carousel>
