Computer graphics pioneer Ken Perlin invented Perlin noise, a foundational tool used in nearly every area of computer graphics. In this episode of CG Garage, Ken shares his unique journey, starting with a childhood love for both art and mathematics. He recounts how his early work on the film Tron inspired him to invent Perlin noise and the foundational concepts of shaders, a breakthrough that laid the groundwork for modern GPUs and the photorealistic visuals we see today. His presentation of this work at SIGGRAPH in 1984 directly influenced companies like Pixar and permanently altered the landscape of visual effects.

The conversation extends beyond historical innovation to a compelling discussion about the future. Perlin draws a sharp distinction between VR and XR, predicting that true mass adoption of immersive technology will only happen when devices become socially invisible, much like the iPhone's impact on personal communication. He posits that the future of technology is not about escaping reality but enhancing it, and that the ultimate "killer app" will be the ability to connect with others in a shared virtual space. We also dive into the role of AI as a creative tool, with Perlin arguing that while it's a powerful new medium, it remains a "recombinant" engine that lacks sentience and is ultimately a vehicle for human creativity and expression.
