The mixed rendering system includes a client device configured to perform: determining at least one user-interactable object of a virtual environment; rendering the at least one user-interactable object; receiving a background scene frame of the virtual environment; blending the at least one rendered user-interactable object with the background scene frame as a visual content of the virtual environment; and providing the visual content of the virtual environment.

Aspects of the subject technology relate to electronic devices having multiple renderers. The multiple renderers may include a system renderer that renders system content and application content generated by some applications at the electronic device, and one or more application renderers that render application content generated by one or more other corresponding applications.

A minimal volumetric 3D transmission implementation enables efficient transmission of a 3D model to a client device. A volumetric 3D model is generated using a camera rig to capture frames of a subject. A viewer is able to select a view of the subject. A system determines an optimal subset of cameras of the camera rig to utilize to capture frames to generate the volumetric 3D model based on the viewer's selected view. The volumetric 3D model is transmitted to the user device. If the user changes the view, the process repeats, and a new subset of cameras are selected to generate the volumetric 3D model at a different angle.

When an operation detection unit (31) (detection unit) of a mobile terminal (30a) (information processing apparatus) detects an operation instruction given when observing a 3D model (90M) (3D object), a texture information selection unit (33) (decision unit) selects which texture information (Ta or Tb) that expresses the texture of the 3D model (90M) in a plurality of different formats acquired by a 3D model acquisition unit (32) to use when drawing the 3D model (90M) according to the operation instruction detected by the operation detection unit (31). Then, a rendering processing unit (34) (drawing unit) renders the texture information (Ta or Tb) selected by the texture information selection unit (33) on the 3D model (90M) reconstructed on the basis of mesh information (M) (shape information) so as to draw the 3D model (90M).
