Even Lightwave and Modo do not render in real time. They do continuously render a scene but you have to give them time to complete the render. If you rotate the camera they will re-render the scene (which starts out pixelated and gradually becomes clear). Like Dave says there are some very high end gpu's and systems that come close but there none that do real time rendering especially with ray tracing and other things like final gather and global illumination. Ok, I understand, thanks for the replies. I would really appreciate if you would tell me how this was made Photorealistic male model -- Ten24 - YouTube Because that's what made me wonder in the first place. It doesn't look like it takes time to re-render the scene as the camera rotates. I've been searching the whole day for an answer for this
