Most VR apps suffer from the \u201eplastic effect\u201c. The environment feels sterile, artificial and unconvincing. At VR3D.cz we take a different path. Instead of imitating reality in a complicated way, we directly transfer it into digital space. See how the combination of cutting-edge 3D scanning and optimization for Unreal Engine 5 is changing the game.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

When a 3D graphic designer models a brick wall \u201efrom scratch\u201c, the result is often too perfect. The bricks are the same, the joints are straight. To make the wall look real, the graphic designer has to spend hours creating cracks, moss stains and chips. This is called \u201eenvironmental storytelling\u201c and is very time (and therefore money) consuming.<\/p>\n

Our approach? We just scan the wall.<\/b><\/p>\n\n

Case Study: dragon sculpture by Michal Ol\u0161iak<\/h3>\n

Let us imagine a concrete example from our practice - a monumental dragon sculpture. We have two ways to get it into your VR app:<\/p>\n\n

    \n \t
  1. \n

    Classic way (Hand modelling):<\/b> A senior 3D graphic designer would have to spend 40 hours or more<\/b> sculpting in ZBrush, modeling each scale, estimating proportions from photos, and then hand-painting the textures. Even the best graphic designer brings his \u201eartistic interpretation\u201c to the work. The result will be beautiful, but it will never be exactly the dragon<\/i>.<\/p>\n<\/li>\n \t

  2. \n

    VR3D.cz (3D Scanning & Photogrammetry):<\/b> We'll arrive on site with the equipment. During 2 hours<\/b> we'll collect the data. Then the software RealityCapture<\/b> within about 4 hours<\/b> machine time creates a digital twin with millimetre precision.<\/p>\n<\/li>\n<\/ol>\n

    The result?<\/b> We get a model that not only has perfect proportions, but contains every chisel indentation, every lichen stain, and the exact patina of the material. All this in a fraction of the time of human labour.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Challenge: How to get millions of polygons into glasses?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
    \n\t\t\t\t
    \n\t\t\t\t\t\t\t\t\tThis is where our core expertise comes in. Anyone can scan an object. But getting a raw scan (which often has tens of millions of polygons) into a standalone glasses Meta Quest 3<\/b>, that have the power of a cell phone, that's an engineering discipline.\n

    Unlike PC VR, where we can use technologies like Nanite, we have to do brutal optimization for Quest 3:<\/p>\n\n

      \n \t
    1. \n

      Retopology:<\/b> From a million triangles, we create an optimized network (Low-poly) that has only thousands of polygons but preserves the shape.<\/p>\n<\/li>\n \t

    2. \n

      Baking (Baking textures):<\/b> All details from the original scan (cracks, bumps) are \u201ebaked\u201c into special textures (Normal maps).<\/p>\n<\/li>\n \t

    3. \n

      Result:<\/b> In VR, you see a visually rich, photorealistic object, but the goggle system renders it completely smoothly at 72 frames per second.<\/p>\n<\/li>\n<\/ol>\n

      \n

      Why is this important to the client?<\/b> Because your app won't chop, it won't overheat, and users will be comfortable in it, even if the scene looks like a movie set.<\/p>\n<\/blockquote>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
