    • 0:00 - Introdução
    • A equipe visionOS Safari apresenta novos recursos para a web espacial este ano, incluindo renderização de modelos 3D estereoscópicos, reprodução de mídia imersiva e recursos do Developer Preview, como ambientes de sites.

    • 0:55 - Incorporar modelos 3D
    • A evolução do desenvolvimento para web apresenta o elemento de modelo HTML, possibilitando a incorporação perfeita de modelos 3D em páginas web. Esse novo recurso, que já está disponível por padrão no Safari em visionOS, revoluciona a maneira como os usuários interagem com o conteúdo da web ao oferecer renderização estereoscópica, possibilitando que eles percebam a profundidade e explorem objetos 3D de vários ângulos.

    • 21:24 - Incluir mídias imersivas
    • O suporte a mídias imersivas em sites foi ampliado, possibilitando a incorporação de vários formatos, como vídeos espaciais, de 180°, 360° e de campo de visão amplo. Com o iPhone 15 Pro ou posterior, os usuários podem gravar vídeos espaciais no próprio app Câmera e assistir a eles no Apple Vision Pro.

    • 26:14 - Fornecer um ambiente personalizado
    • Há também um novo recurso do Developer Preview para Safari chamado de ambiente de site. Esse recurso permite a criação de ambientes virtuais nos sites usando arquivos USDZ, possibilitando que os visitantes vivenciem ambientes imersivos, como restaurantes, submarinos ou masmorras, mantendo o Safari e o site em exibição. Para implementar esse recurso, você pode usar uma marcação HTML específica, vincular a arquivos USDZ e personalizar os ambientes com IBLs. Esse recurso está em desenvolvimento, portanto, incentivamos todo e qualquer feedback a fim de moldar seu futuro.
