Abstract: Disclosed are a VR playing method, a VR playing device, and a VR playing system. When using a media playing device for playing, a 3D spherical object is first created in the development environment, and then a new texture material is built and shader options are created for the texture material. After selecting shading for the texture material, a multimedia panoramic material is acquired from the media playing device or an external storage device, and then the texture material and the multimedia panoramic material are loaded onto the surface of the 3D spherical object. Finally, a virtual camera module is arranged at the center of the 3D spherical object. The angle of the virtual camera is controlled to pick up content of the multimedia panoramic material to play on the media playing device.

Abstract: Disclosed are as represented by Formula (I) a quinazoline derivative and a pharmaceutical acceptable salt thereof, or, an enantiomer, a non-enantiomer, a tautomer, a racemate, a solvate, a metabolic precursor, or a prodrug of both. Also disclosed are a preparation method therefor, an intermediate, a pharmaceutical composition having the quinazoline derivative, and an application thereof. The quinazoline derivative of the present invention is provided with improved anti-tumor activity.
