Abstract: In various implementations, methods and systems for drawing in a three-dimensional (3D) virtual reality environment are provided. An intersection between a user input and an object, associated with a three-dimensional (3D) virtual reality environment is identified. An anchor position is determined for a drawing surface based on the identified intersection. A gaze direction of a user in the 3D virtual reality environment is identified. A drawing surface configuration for the drawing surface with respect to the 3D virtual reality environment is determined based on the gaze direction, where the drawing surface configuration indicates how the drawing surface is defined in the 3D virtual reality environment. The drawing surface is defined in the 3D virtual reality environment at the determined anchor position with the determined drawing surface configuration. A drawing is generated on the drawing surface based on drawing input.

Abstract: Camera and sensor augmented reality techniques are described. In one or more implementations, sensor data is obtained from a sensor of a hardware device, the sensor data being associated with the hardware device that is located in an environment, such as in three-dimensional (3D) space. Images of the environment are captured with at least one camera of the hardware device. A position of the hardware device in the environment can then be determined based on at least one of the sensor data and the images of the environment. Further, an orientation of the hardware device in the environment can be determined based on at least one of the sensor data and the images of the environment.

Abstract: Augmented reality extrapolation techniques are described. In one or more implementations, a frame of an augmented-reality display is rendered based at least in part on an optical basis that describes a current orientation or position of at least a part of a computing device. While the frame is rendered, an extrapolation based on a previous basis and a sensor basis generates an updated optical basis that describes a likely orientation or position of the part of the computing device, and the extrapolation is effective to account for a lag time duration between rendering the frame and displaying the frame of the augmented-reality display. The rendered frame of the augmented-reality display is updated before the rendered frame is displayed based at least in part on the updated optical basis that describes the likely orientation or position of the part of the computing device.

Abstract: Camera and sensor augmented reality techniques are described. In one or more implementations, an optical basis is obtained that was generated from data obtained by a camera of a computing device and a sensor basis is obtained that was generated from data obtained from one or more sensors that are not a camera. The optical basis and the sensor basis describe a likely orientation or position of the camera and the one or more sensors, respectively, in a physical environment. The optical basis and the sensor basis are compared to verify the orientation or the position of the computing device in the physical environment.

In one or more implementations, a plurality of color channels obtained from a camera are examined, each of the color channels depicting an optical marker having a different scale than another optical maker depicted in another one of the color channels. At least one optical marker is identified in a respective one of the plurality of color channels and an optical basis is computed using the identified optical marker usable to describe at least a position or orientation of a part of the computing device.
