Alexander Larsson, sviluppatore di Flatpak e attivo membro della comunit\u00e0 GNOME, ha pubblicato<\/a><\/noindex> seconda edizione del progetto Gthree<\/a><\/noindex>, che sviluppa un porting della libreria 3D three.js<\/a><\/noindex> per GObject e GTK, che pu\u00f2 essere utilizzato per aggiungere effetti 3D nelle applicazioni GNOME. L'API di Gthree \u00e8 praticamente identica a three.js, includendo un caricatore glTF<\/a><\/noindex> (GL Transmission Format) e la possibilit\u00e0 di utilizzare materiali basati su PBR (Physically Based Rendering) nei modelli. La resa supporta solo OpenGL.<\/p>\n

Nella nuova versione \u00e8 stata aggiunta la supporto della classe Raycaster<\/a><\/noindex> con l'implementazione dell'omonimo metodo di rendering<\/a><\/noindex>, che pu\u00f2 essere utilizzato per determinare su quali oggetti nello spazio 3D si trova il mouse (ad esempio, per selezionare oggetti 3D dalla scena con il mouse). Inoltre, \u00e8 stato aggiunto un nuovo tipo di illuminazione puntuale (GthreeSpotLight) e fornita supporto per le mappe delle ombre, che consentono agli oggetti posti davanti alla fonte di luce di proiettare ombre sull'oggetto target.<\/p>\n
