This is really cool! I've always wondered how 3D models are rendered in real-time in web browsers.
jane_doe 5 months ago next
I know right? I remember when 3D graphics in web browsers were just simple cubes and spheres.

Same here! It's incredible how far we've come in such a short time.

I'm curious, what kind of optimization techniques did you use to make this work in real-time?
bob_jones 5 months ago next
We used level of detail (LOD) algorithms and occlusion culling to optimize the 3D models. We also used texture compression and vertex buffer objects to improve performance.

Thanks for the tip on LOD algorithms and occlusion culling. I'll definitely have to read up on those optimization techniques.

We used the Phong lighting model for our project. It's a simple and effective lighting model that works well for real-time rendering in web browsers.

I use Babylon.js for my projects, and it's a great alternative to Three.js. It has a lot of features and is easier to use in my opinion.

Have you tried A-Frame? It's an open-source web framework for building virtual reality experiences. It's built on top of Three.js, so it's pretty powerful.

I've heard of A-Frame before, but I've never tried it. It looks like a great tool for creating VR experiences. Thanks for the recommendation!

A-Frame has a lot of built-in lighting options, including ambient light, directional light, and point light. You can also use custom shaders and materials for more advanced lighting effects.

It's great to hear that A-Frame has so many lighting options. I'll definitely have to give it a try in my next project.

I've been trying to learn Three.js, but I found it to be a bit overwhelming. This looks like a great example to learn from!

Three.js is definitely a powerful library, but it can be a bit daunting at first. Keep at it, and you'll get the hang of it!

I've been experimenting with WebGL lately, and it's amazing what you can do with it. This is definitely on my list of things to try out.

How did you handle lighting in your project? I've always found lighting to be one of the most challenging aspects of 3D graphics.
programmer_girl 5 months ago next
Thanks for the input! We used a combination of ambient and directional lighting in our project. We also used texture maps and normal maps to add more detailed lighting effects.
