Why Does My glTF Model Look Different Depending on Where I Am?

I’ve been experimenting with a web tool that allows me to load and view glTF models, and I’ve noticed something fascinating—my models sometimes look slightly different depending on where I am. At first, I thought it was just my imagination, but after comparing the same glTF model in different locations, I started noticing subtle variations. The lighting, shadows, and sometimes even how the textures appear seem to shift, but I can’t figure out why.

I was inspired by this idea positively because it made me think about how much our environment affects the way we perceive 3D objects. Whether I’m in my home office with warm lighting or outside in natural daylight, the way I see colors and reflections changes. This made me wonder: could this effect be exaggerated when using a glTF viewer due to some unexpected interactions between ambient light settings and my display?

This brings me to the question: “Where is this?” (dimana ini?) —a phrase that defines more than just a physical location. It reflects how different environmental conditions, device settings, and even personal perception can alter how we see the same object. When we ask “Where is this?” in the context of 3D rendering, we aren’t just talking about geographical position but also about the virtual conditions that affect how a model appears. If my glTF model looks different, is it because of my surroundings, my screen, or something within the rendering engine itself? Understanding where we are—both physically and digitally—can play a huge role in how we interpret visual data.

Here’s what I’ve tried so far:

  • I’ve viewed the same glTF model in multiple browsers, but the difference persists.
  • I’ve checked my screen brightness and color calibration settings, but that doesn’t fully explain it.
  • I’ve tested on different devices, including a laptop and a phone, and the variations are still noticeable.
  • I’ve looked into the environment maps used in the viewer, but even with a neutral background, I see some differences.

Has anyone else experienced this? Could it be that the web tool automatically adjusts environmental lighting based on device sensors? Or is it possible that some glTF files react differently to ambient light settings based on how they were exported? I’d love to hear from others who have encountered something similar and found ways to manage these differences.
