I agree with you. That image makes me distrust the tutorial like maybe it's not actually using ray tracing. That image certainly does not look ray traced. There is no radiance what so ever. It looks forward rendered with standard phong shading and shadow maps.
- banachtarski 7y agoYou probably are not the target audience. As a graphics engineer, the more compelling use cases of ray tracing are things like visibility tests, which can be temporally stabilized by adding a low-discrepancy noise to each sample and used to perform leak-free global illumination. Samples can be used to feed other aspects of the pipeline like generating soft shadows, or atmospheric effects, etc. It's an API tutorial, for professionals in the field. Ray tracing is just one tool in the toolbox, not the alpha and omega of how the frame gets composed.
