Abstract: Facilitating the fit of a head mounted device includes calculating a nominal interocular distance (IOD) using a nominal eye model. A device IOD is based on a distance between a first optical module and a second optical module of the headset. The device IOD is compared to the calculated nominal IOD. If a difference between the device IOD and the calculated nominal IOD satisfies a threshold, an adjustment process is initiated to modify the distance between the first optical module and the second optical module.

Abstract: Various implementations disclosed herein include devices, systems, and methods for providing a view of a three-dimensional (3D) environment by rasterizing vector graphics (e.g., text) on separated two-dimensional (2D) assets within the 3D environment. For example, a process may include obtaining drawing commands corresponding to a vector graphic to be displayed. The process may further include obtaining fall-off data corresponding to changes in perception of resolution for different portions of a display and obtaining viewer position data corresponding to a viewpoint position for the view. The process may further include determining a scale factor for the rasterizing the vector graphic and providing a texture (e.g., image) on a surface of the asset within the 3D environment by rasterizing the vector graphic using the drawing commands and the scale factor. The process may further include rendering a view of the 3D environment based on the viewpoint position.
