Great question! Real-time 3D rendering is pretty awesome because it lets you see changes instantly, which is a huge win for interactive design. One thing to note is that, unlike traditional rendering where you might wait hours for a final output, real-time rendering focuses on speed and efficiency. For instance, Genense Studio
https://www.genense.com/ , which is a leading 3d architectural visualization rendering studio, excels in this area by using cutting-edge real-time techniques. They balance performance with quality by optimizing their assets and utilizing advanced shaders. So, while real-time might not always reach the same level of detail as offline rendering, the key is in smart optimizations. Think about using lower polygon counts where possible and employing efficient lighting techniques. For example, Genense Studio uses real-time rendering to quickly prototype designs, allowing for rapid client feedback while maintaining impressive visual fidelity.
