YES I've been waiting for the better part of 20 years ever since the like of games such as gmod (half life 2 physics engine) featured object interactions where they just phase through each other if you push on them hard enough. I'm so happy that finally we're getting proper collision calculations. it's taken way too long to get here.

@naidoelcam1215 3 года назад

There are other fixes already. CS:GO used a method where if a part of a model is cut by a plane of another object, the object is set to invisible past that point. In this way collision and getting stuck due to where you are looking does not occur while no one else will see your gun poking through the other side of the door. Using this method is more for realism in collisions which you wouldn't want. Another common fix is to just have an animation where the character raises their weapon up to avoid hitting into the object. Some older games use similar strategies and people get frustrated with the collisions and what feels like clunkiness in the controls and design of map.

This is game changing, literally. One of the biggest immersion breakers for me when in a game be it VR or regular is the fact that objects can sometimes not collide properly. It makes the world feel fake. With this new technique even just looking at stuff like the dragon and cloth it just feels incredibly real and its faster to boot!

I'm kind of weird because when collisions don't work I expect it because it's game logic and I kind of don't think about it because I'm already immersed in the alternate reality

It probably wont run in video games, the 5 milisecond result is when all of the computers resources are dedicated to running the single task, in a game a lot of things need to happen parallel to each other, so in a video game this new method will need to ise only minimal resources and it won't be as fast

SDF representation is super useful for a lot of things, because it makes your effective resolution for stuff like rendering and intersection calculation several orders of magnitude higher (which then means you can decrease the actual resolution while still having higher effective resolution).

@Evandroworks 3 года назад

I can see some kind of bulbous deformation or invisible "force field" in the cloth present at the dragon's horn, or at the rope collision area with the pillar corner. At the horn you can see that the cloth is rounder than how the horn was pointier. And at the rope you can see it bent right on top of the pillar as if there was some invisible cushion between it and the pillar. Still, its a dozen times better than the previous method, and with such a short computation time it could probably be finetuned to achieve more precision at the cost of some milliseconds per frame.
