    Arkadiusz Szadkowski : Splats vs Points vs Mesh


    🔸 Gaussian Splats: imagine throwing thousands of tiny ellipsoidal paint drops. They overlap, blend, and create a smooth, photorealistic look. Fast, great for visualization, but less structured for measurements.

    🔸 Point Clouds: every dot is a measured hit. LiDAR or photogrammetry gives us millions of them forming a constellation of reality. Amazing for accuracy, but they don’t connect the dots out of the box.

    🔸 Meshes: take those points, connect them into triangles, and you get very realistic surfaces. Strong for 3D analysis, simulation as continues watertight models.

  • Space bodies’ components and light spectroscopy

    This help’s us understand the composition of components in/on solar system bodies.

    Dips in the observed light spectrum, also known as, lines of absorption occur as gasses absorb energy from light at specific points along the light spectrum.

    These dips or darkened zones (lines of absorption) leave a finger print which identify elements and compounds.

    In this image the dark absorption bands appear as lines of emission which occur as the result of emitted not reflected (absorbed) light.
