VRLensMod
About
A client-side Fabric mod for Minecraft *.21.11 that forces a side-by-side stereoscopic view with circular barrel-distorted lenses. Injects via WorldRenderEvents on client startup using the ****-processing pipeline. The GLSL shader splits the viewport at midline, applies a 1mm center-*** shift, runs a radial barrel distortion coefficient loop, and masks pixels outside a 0.49-radius circle to solid black, creating two perfect circular VR-***** lenses on a flat screen.
