Ai getting better and better

[obsidian]

Here’s a 3D scene rendered with ray tracing. Notice the lighting - the bike’s shadows falling on the first car, and the first car’s shadows cast onto the second. Also take a look at the reflections in the spheres. These are ray-traced reflections and shadows — something AI-generated “reflections” can only fake for now and can’t accurately reproduce anytime soon.

For these renderings, I used an infinite sphere without a ground texture. Because of that, the tire tracks shift between views. It’s possible to render with a finite sphere and a defined ground plane instead, which can then be scaled so the footprints appear correctly sized and remain consistent across views. However, that approach introduces visible distortion where the finite sphere meets the ground plane. To avoid that issue, I rendered this scene using just the infinite sphere.

Same scene with a different HDRI and zoomed out a bit more.

The tires are obviously too clean. With effort sand and debris can be added so it looks more integrated with the scenes. These were just quick studies to illustrate the ray traced shadows and reflections.

Thanks for estabilishing my greatness with that logo Obsie!

Amazing.

This is AI

3× slow motion. These GIFs look jumpy and are heavily downscaled — the original 4K animations at 120 FPS look much smoother.

Haha glad I could help!

The AI videos of chiropractors throwing old ladies through walls are fantastic.

Haha the AI you always wanted!

This looks interesting! Animating in 3D is hard. AI to the rescue?!

OOOOOO YEEEEEEAH

Kwon, check out the parts where the AI actors are standing in the rain — there are no raindrops bouncing off their bodies. It looks more like a rain filter or video layer composited over the footage in DaVinci or Premiere, rather than real interaction. I’m still waiting for AI to truly match real-world physics. The lighting, shadows, and reflections all look generic, based on whatever the model was trained on. I wonder if AI models will eventually be able to factor in ray tracing to make it look physically accurate.

Spot on

Duly noted, ai CAN handle rain physics today, it just takes so much longer time

I will show you some good rain physics and bodily interaction soon
