This extension can significantly decrease rendering overhead when producing 3d content for displays with multiple viewpoints, including Virtual Reality, Augmented Reality and Holographic systems. AlphaPixel originally developed this code for a client using the VARJO VR/AR headsets and then funded Robert and OpenSceneGraph Professional Services to adapt and integrate the code into mainline OpenSceneGraph to make it available for all users.</span></p><br><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-size:11pt;font-family:Arial;color:rgb(0,0,0);background-color:transparent;font-variant-numeric:normal;font-variant-east-asian:normal;vertical-align:baseline;white-space:pre-wrap">MultiView2 allows an OpenGL program to render a scene once while the GPU rasterizes it multiple times from slightly different viewpoints, making production of stereo parallax views substantially faster where the CPU-side cull and draw operations are expensive. This optimization can reduce the time penalty of drawing additional related views by up to 90%, which can nearly double stereo framerate, or make scenes with more than two views many times faster. This is especially effective on 4-channel displays like foveated xR headsets such as VARJO ( </span><a href="https://developer.varjo.com/docs/native/foveated-rendering-api" style="text-decoration-line:none"><span style="font-size:11pt;font-family:Arial;background-color:transparent;font-variant-numeric:normal;font-variant-east-asian:normal;text-decoration-line:underline;vertical-align:baseline;white-space:pre-wrap">https://developer.varjo.com/docs/native/foveated-rendering-api</span></a><span style="font-size:11pt;font-family:Arial;color:rgb(0,0,0);background-color:transparent;font-variant-numeric:normal;font-variant-east-asian:normal;vertical-align:baseline;white-space:pre-wrap"> ).</span></p><br><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-size:11pt;font-family:Arial;color:rgb(0,0,0);background-color:transparent;font-variant-numeric:normal;font-variant-east-asian:normal;vertical-align:baseline;white-space:pre-wrap">Prototype support is also included for plenoptic/holographic/lightfield displays such as the Leia Inc Lume Pad lightfield Android tablet ( </span><a href="https://www.lume-pad.com/" style="text-decoration-line:none"><span style="font-size:11pt;font-family:Arial;background-color:transparent;font-variant-numeric:normal;font-variant-east-asian:normal;text-decoration-line:underline;vertical-align:baseline;white-space:pre-wrap">https://www.lume-pad.com/</span></a><span style="font-size:11pt;font-family:Arial;color:rgb(0,0,0);background-color:transparent;font-variant-numeric:normal;font-variant-east-asian:normal;vertical-align:baseline;white-space:pre-wrap"> ), and the architecture is also well-suited for driving displays such as the Avalon Holographics 29” Holographic Display ( <a href="https://www.avalonholographics.com/products">https://www.avalonholographics.com/products</a> ).
