Awesome work on the rendering engine! I've been working on something similar and I'm curious, what were some of the biggest challenges you faced in the process?

The hardest part for me was definitely optimizing the shaders for real-time performance. I ended up using a proprietary library to handle some of the heavy lifting. What approach did you take?

I have to agree with dave_engineer. Optimization was definitely the most challenging part for me as well. I ended up using a few open-source libraries to help speed things up. Which libraries did you use?
code_master 6 months ago next
I used a mix of proprietary and open-source libraries. One of the open-source ones I liked the most was ObjExporter, which made it really easy to import 3D models. I highly recommend it!

This is so cool! I've always been fascinated by graphics and rendering engines. How long did it take you to build this all from scratch?
code_master 6 months ago next
It took me about 6 months to get to a point where I was happy with the performance and features. I've been continually iterating and adding new features since then. It's a never-ending process!

Really impressive work! I'm looking to improve my own rendering engine and would love to hear more about your experience with real-time rendering.

Glad to hear you're interested! Real-time rendering is all about achieving high frame rates and smooth animations. I found that the key to success was breaking the rendering pipeline down into smaller, more manageable pieces.

That makes a lot of sense. I'll definitely try breaking it down like you suggested. Thanks for the advice!

Wow, this is amazing. I'm trying to get into real-time rendering myself, but the learning curve is pretty steep. What resources would you recommend for someone just starting out?
code_master 6 months ago next
I definitely recommend starting with some online courses to get a feel for the basics. Check out some courses on Udemy or Coursera that cover shader programming,3D graphics, and game engines. That's where I started and I found it really helpful.

@programmin_pete I also second the recommendation for online courses. I found the Learning Cocos2D tutorials to be really helpful when I was first starting out. They're focused on game development, but they're great for learning the fundamentals of real-time rendering.

Incredibly impressive work with the engine! I'm working on a new game prototype and I'd love to use a rendering engine like this. Do you plan on releasing it as open-source or offering it as a commercial product?
code_master 6 months ago next
Thanks! I'm actually planning on releasing it as open-source within the next few months. I want to make sure it's stable and well-documented enough to be useful for other developers first. Stay tuned!

I'm blown away by the level of detail in your renderings. How did you manage to get such great results with real-time rendering? Do you have any tips for improving image quality?
code_master 6 months ago next
Thank you! I think the key to great results is to focus on the fundamentals. First, make sure you have a good understanding of lighting and shading. Then, spend a lot of time tweaking your textures and materials to get them just right. It's a lot of work, but it's definitely worth it!

Very impressive work! I'm curious, what was your approach to handling physics and animation in real-time? That's always been a pain point for me when working with 3D graphics.
code_master 6 months ago next
Thanks! I used a physics engine called Panda3D to handle most of the heavy lifting for physics. It has a lot of great built-in features for animating characters and objects, which made it a lot easier to work with. Highly recommend giving it a try!

This is incredible work. Real-time rendering is the future of graphics and I'm blown away by what you've accomplished. Can't wait to see what you do next!

Really interesting stuff. I'm curious how your rendering engine compares to popular game engines like Unity and Unreal. Do you think there's still a place for engines like yours in modern game development?
code_master 6 months ago next
Thanks! I think there's definitely still a place for engines like mine, especially for developers who want more control over the rendering pipeline and kernel functions. My engine is more lightweight and flexible than Unity or Unreal, so it's well-suited for smaller projects or custom applications. But, of course, there are trade-offs to be made in terms of features and ease of use. It all depends on what you need!
