Systems and methods for adjusting a stereoscopic effect
The technology described herein presents systems and methods for adjusting the visual effect of the image, particularly with respect to the stereoscopic effect. In one example embodiment, the technology can determine if a “collision” is detected between the virtual camera position and then adjust a parameter of the virtual camera based on the point of intersection associated with the “collision.”
1. A system configured to adjust a stereoscopic image, comprising:
a processor; and
a memory operatively coupled to the processor and storing computer readable instructions that, when executed by the processor, cause the system to:
position at least one virtual camera in a virtual three-dimensional space;
set a reference virtual plane of the virtual camera based on a position of a virtual player character object;
based on a line between a viewing position of the virtual camera and the virtual player character object, determine if an intersection exists at a position along the line where the line intersects with an object in the virtual three-dimensional space;
adjust the reference virtual plane of the virtual camera based on the position along the line where the intersection exists, wherein a distance between the adjusted reference virtual plane and the position of the virtual camera in the virtual three dimensional space corresponds to a distance between the position along the line where the intersection exists and the position of the virtual camera in the virtual three-dimensional space; and
generate for display a stereoscopic image showing the virtual three-dimensional space from a perspective of the viewing position of the virtual camera.
2. The system of claim 1 , wherein the intersection exists when the position along the line intersects with level geometry of game terrain in the virtual three-dimensional space.

adjust a reference virtual plane of the first virtual camera based on the position along the first line where the intersection exists, wherein a distance between the adjusted reference virtual plane and the position of the first virtual camera in the virtual three dimensional space corresponds to a distance between the position along the first line where the intersection exists and the position of the first virtual camera in the virtual three-dimensional space; and
