For a 400㎡ dome space with a 9-metre ceiling height, aligning 19 projectors across a curved surface can involve complex adjustments and significant commissioning time.\u003Cbr>\u003Cbr>For the Wushang Longmen Immersive Experience Hall at Longmen Grottoes in Luoyang, hecoos supported the complete spherical mapping and playback workflow, providing the technical foundation for a large-scale immersive dome experience.\u003Cbr>\u003Cbr>\u003C\u002Fp>\u003Ch2>Technical Specifications\u003C\u002Fh2>\u003Cspan style=\"font-weight: bold;\">Display Space:\u003C\u002Fspan> 400㎡ dome\u003Cbr>\u003Cspan style=\"font-weight: bold;\">Ceiling Height: \u003C\u002Fspan>9 metres\u003Cbr>\u003Cspan style=\"font-weight: bold;\">Projection System:\u003C\u002Fspan> 19 projectors\u003Cbr>\u003Cspan style=\"font-weight: bold;\">System Configuration: \u003C\u002Fspan>3 hecoos servers in a one-to-two output setup\u003Cbr>\u003Cspan style=\"font-weight: bold;\">Content Output:\u003C\u002Fspan> 19 channels of 2K projection signals\u003Cbr>\u003Cbr>\u003Ch2>Previsualizing the Dome Experience Before Installation\u003C\u002Fh2>Large-scale dome projection requires careful planning before equipment deployment.
