Real-time Rendering: Is Ray Tracing Necessary?

  ## Speed vs. Perfection
  
  Visualization has bifurcated into two distinct paths: the ultra-fast real-time engines and the physically accurate ray tracers.

  ### The Rise of Real-Time
  Tools like Lumion, Enscape, and Twinmotion have democratized rendering. You no longer need a render farm to produce beautiful client presentations. The feedback loop is instant, allowing for live design sessions.

  ### When Ray Tracing Matters
  Despite the quality of rasterization, ray tracing (V-Ray, Corona) is still king for high-end marketing imagery where light behavior, caustics, and material depth must be 100% accurate.
