matrix_4_4
: a pointer to a previously created perspective matrix, made up of 16 floats.data
: get filled with a number of useful values used to compute the perspective matrices.num_horizontal_views
and num_vertical_views
: give the library an idea of how many cameras will be used during rendering.system_disparity_in_pixels
: a value retrieved from the Leia System Service.baseline_scaling
: this is a scalar for how far beyond the system disparity you would like. For example, by setting baseline_scaling
to 2.0, you will double the amount of disparity compared to if you set baseline_scaling
to 1.0. The larger the value, the more objects will appear to pop out or into the screen, but larger values may cause you to lose the effect altogether.convergence_distance
: In world space, this is the location where an object looks exactly the same from all views. This value should fall between near
and far
. Objects between near
and convergence_distance
(but not AT convergence_distance
) will appear to pop out of the screen, while objects between convergence_distance and far will appear to fall into the screen.view_resolution_x_pixels
and view_resolution_y_pixels
: the size of each view the Leia Camera will render into. These values can be retrieved from Android using SimpleDisplayQuery, and are a value smaller than the resolution of the screen based on orientation.
