nn::ulcd::CTR::StereoCamera::GetParallax Member Function

#include <nn/ulcd.h>

f32 GetParallax(
     const f32 distance
) const;

	Name	Description
in	distance	Distance from the camera.

Amount of offset, both to the left and right, of an object at the specified location (as a ratio with 1.0f = 100%).

Gets the ratio of the parallax at a point located a specified distance away from the camera to the screen width.

This function calculates and returns a value indicating the screen ratio by which to shift an object for both the left and right cameras at a distance specified by distance, where 1.0f indicates 100% (in other words, the return value is half of the offset between the images for the left and right eyes).

If a negative value is specified for distance, it returns 0.0f. It returns a positive value for objects located beyond the base plane. It returns a negative value for objects located in front of the base plane.

The results from this function are calculated based on the results obtained during the last call to the CalculateMatrices* functions.
