For working in transparent AR, especially with head-mounted devices like HoloLens, an intuitive UI is essential. This UI must differentiate itself from the 3D GUIs designed for VR.… Read more: Does it make sense to consider dual displays for augmented reality ?

Gaussian splats are emerging as a notable field in computer graphics. In this exploration of adapting Gaussian splat solutions for AR viewing on the MS HoloLens 2, I relied heavily on the Quaternar middleware to bring my vision to fruition. Starting with the open-source SIBR_Viewer, I faced challenges because of its anaglyph stereo base. But it was the integration of the Quaternar library that was pivotal in my efforts to adapt it for AR. Yet, this integration was not without its hurdles, such as mismatched coordinate systems and the specifics of the HoloLens 2 laser projection system. A particularly noteworthy finding was the absence of the Alpha channel in Holographic Remote Rendering, which has a profound impact on AR visualization and blending.
