The Future of Rendering

AI, Art from another World?

AI-powered tools are rapidly emerging and every day more of them are being developed. With these tools, you can create stunning 2D and 3D art using just text. The results are fast and impressive, making it a great time-saver. However, some AI tools scrape existing artwork from other artists, mix them together in a new context, and present the result as a “new” image.

AI can be a useful tool to enhance your renderings, but be aware that AI-generated content may not be original and could potentially infringe on copyright laws.
AI has the potential to become very dangerous. For example, it can be used to create a fake video by taking someone’s face and then matching it precisely with a new audio recording. This technology can be abused for harmful purposes by certain groups. In Switzerland and other countries, efforts are underway to create new laws that define what AI can and cannot do.

AI is transforming the way we render 3D art by providing faster and more efficient tools. However, it is important to note that AI cannot replace the entire rendering process. Also, images generated by AI cannot be easily controlled and specific changes are difficult to make. Any changes made to the image affect the whole image. Despite this, use AI into our creative processes can help us gain inspiration, speed up the workflow, and add depth to our 3D work. Therefore, there is no harm in using AI in our workflows..

Realtime Rendering

Rendering times are always too long. Even new PC setups can become slow very quickly, taking anywhere from 1 to 30 hours per frame or even more. Is this a sustainable practice for the future? especially with the rising cost of energy and increasing climate changes worldwide?
There are several software programs that use real-time rendering. Unreal Engine being one of the largest and most commonly used. Other options like Lumen, Chaos Vantage, G5 Renderer, and others that have jumped on the fast-moving train. Keep in mind
that Realtime Rendering is the future, but not the solution to everything yet.

What are the differences between these two rendering technologies? Here are some of the biggest:

Realtime RenderingOffline Rendering
the rendering process can be fast, but it requires strong system specificationscan be slow but it can also run on older systems, but it may take longer. Newer systems can speed up the rendering time.
the accuracy of the rendering may not be consistent in some partsit is of high quality and accurate.
the process is interactive and fast, which makes it suitable for collaboration, design workflows and on-the-fly changes.the process is not interactive and changes take a lot of effort and time.
the lighting quality of the rendered image may be less accuratelighting quality is accurate
users can view the image /product from all angles in real-timestick to on perspective per Image
more points can be added but the list will become way to long

Realtime Engine vs Offline Rendering

This Webinar covers a lot of that Topic very worth watching it.


When you use realtime and when offline Rendering?

Real-time engines use various technologies tricks to speed up the calculations for the final output. Some techniques may appear to be cheating, resulting in an output that looks good but is not entirely accurate. This is why real-time renderings often have a “game look.” While this may not a bad thing, it is necessary to maintain fast and interactive performance.

The choice between using real-time and/or offline rendering depends on the goals of you or your client. If the client wants to see a quick and comprehensive view of the product from all angles, or if it’s part of a collaborative work process with frequent changes, then real-time rendering is the way to go. This is also suitable for web and VR/AR applications where accuracy is not a top priority, but appearance is important.

However, if the client wants a highly accurate and high-quality visualization of the product, and is willing to give you time to produce it, then offline rendering is the best option. This is especially true when interactivity is not important.

It’s possible to mix these two technologies together if you have a well-prepared model for real-time rendering that can also be used for offline rendering, and vice versa.

Looking ahead, the development of real-time rendering is exciting. It’s possible that someday, no one will talk about offline rendering anymore. Nonetheless, it’s important to always keep creativity alive.
