Config.TextureUpdateMode

Page Summary

Config.TextureUpdateMode describes how ARCore updates the camera texture.
The default mode is BIND_TO_TEXTURE_EXTERNAL_OES, which provides the camera image through a GL_TEXTURE_EXTERNAL_OES texture.
EXPOSE_HARDWARE_BUFFER mode provides the camera image through a HardwareBuffer, which is accessible via Frame.getHardwareBuffer().
EXPOSE_HARDWARE_BUFFER mode is only available on Android API levels 27 and above.

public static final   enum Config.TextureUpdateMode

Describes how ARCore will update the camera texture. See Vulkan Rendering developer guide for more information.

 BIND_TO_TEXTURE_EXTERNAL_OES

ARCore provides the camera image through the GL_TEXTURE_EXTERNAL_OES texture provided to Session.setCameraTextureName(int) or Session.setCameraTextureNames(int[]) .

This is the default mode.

 EXPOSE_HARDWARE_BUFFER

ARCore provides the camera image through a HardwareBuffer . The hardware buffer for a Frame is accessible via Frame.getHardwareBuffer() . See documentation on Native Hardware Buffer in the Android NDK.

The client app is responsible for binding it to a GL_TEXTURE_EXTERNAL_OES (OpenGL ES) or VkImage (Vulkan).

This is only available on Android API levels 27 and above. Using Session.configure(Config) to set EXPOSE_HARDWARE_BUFFER on an incompatible device will throw UnsupportedConfigurationException .
