Systems and methods for procedural rendering of cinematic virtual reality content

A method being implemented by a computing system including one or more physical processors and storage media storing machine-readable instructions, the method comprising:

• obtaining interactive content, the interactive content including a stereoscopic equirectangular video frame;
• generating a UV coordinate screen space, the UV coordinate screen space corresponding to a physical screen of an interactive content player device;
• computing a first location of the UV coordinate screen space, the first location of the UV coordinate screen space comprising a first center of a first portion of the UV coordinate screen space;
• computing a second location of the UV coordinate screen space, the second location of the UV coordinate screen space comprising a second center of a second portion of the UV coordinate screen space;
• selecting a point of the UV coordinate screen space to procedurally render, the point to procedurally render being within the first portion of the UV coordinate screen space or the second portion of the UV coordinate screen space;
• computing virtual spherical coordinates using the point of the UV coordinate screen space to procedurally render, the computing the virtual spherical coordinates comprising projecting a line from an origin of a virtual sphere through a plane at the point of the UV coordinate screen space to procedurally render, the plane lying at a radius of the virtual sphere, and subsequently deriving an azimuth value and an altitude value based on the projected line;
• obtaining a rotation matrix;
• rotating the virtual spherical coordinates using the rotation matrix;
• determining equirectangular UV coordinate values within the stereoscopic equirectangular video frame using the rotated virtual spherical coordinates, the equirectangular UV coordinate values being based on a rotation of the azimuth and altitude values;
• identifying pixel values of the stereoscopic equirectangular video frame using the equirectangular UV coordinate values;
• and
• returning the pixel values of the stereoscopic equirectangular video frame for the UV coordinate screen space, thereby causing a corresponding presentation on the physical screen of the interactive content player device.
