Native VR Media Applications
Oculus Cinema uses the Android
MediaPlayer class to play videos, both conventional (from
Movies/ and
DCIM/) and side by side 3D (from
Movies/3D and
DCIM/3D), in a virtual movie theater scene (from
Oculus/Cinema/Theaters). See
Mobile VR Media Overview for more details on supported image and movie formats.
Before entering a theater, Oculus Cinema allows the user to select different movies and theaters.
A theater is typically one big mesh with two textures. One texture with baked static lighting for when the theater lights are one, and another texture that is modulated based on the movie when the theater lights are off. The lights are gradually turned on or off by blending between these two textures. To save battery, the theater is rendered with only one texture when the lights are completely on or completely off. The texture with baked static lighting is specified as the diffuse color texture. The texture that is modulated based on the movie is specified as the emissive color texture.
The two textures are typically 4096x4096 with 4-bits/texel in ETC2 format. Using larger textures may not work on all devices. Using multiple smaller textures results in more draw calls and may not allow all geometry to be statically sorted to reduce the cost of overdraw. The theater geometry is statically sorted to guarantee front-to-back rendering on a per triangle basis which can significantly reduce the cost of overdraw.
In addition to the mesh and textures, Oculus Cinema currently requires a 350x280 icon for the theater selection menu.
Oculus 360 Photos is a viewer for panoramic stills. The SDK version of the application presents a single category of panorama thumbnail panels which are loaded in from
Oculus/360Photos. See
Mobile VR Media Overview for details on creating custom attribution information for panoramas.
Oculus 360 Videos works similarly to 360 Photos as they share the same menu functionality. The application also presents a thumbnail panel of the movie read in from
Oculus/360Videos which can be selected to play. See
Mobile VR Media Overview for details on the supported image and movie formats.
