> Films don’t model in “polygons” I can promise you they do. They are treated as the same thing. Everyone uses polygons knowing they will be smoothed/subdivided/declared as subdivision surfaces. Sharp edges, cusps and bevels

I'm not advocating, I'm explaining why it already happened twenty years ago. Polygons can be trivially subdivided to a rounded surface or converted to a subdivision surface. This is something anyone who has used maya, houdini, l

The original thread was about nurbs not being used anymore over polygons. Displacement doesn't change the equation between polygons and nurbs of course because they both go in as high level primitives. Hair is a its own thing of cours

I'm guessing at this point you are purposely ignoring what I'm saying, but again, I'm explaining why it isn't used in production 3D very often. I know how to collide rays with csg, I'm trying to get you to think abo

I didn't say it was impossible, I'm talking about why these other geometry types aren't typically used instead of polygons. I asked 'how do you trace rays against it' because to do it directly is not fast, yet you

Multiple gigabytes of geometry is a lot. That ends up working out to potentially dozens of hundreds of polygons per pixel. Even so the person I was replying to seemed to wonder why everything converted to polygons, which is because of a mo

Right, but the rest of the questions remain, along with the usefulness of CSG in real scenarios. CSG can be interesting, but it does end up being very impractical for anything except for some specific effects that are then turned into poly

And what do you subdivide it to? How do you trace rays against it? How do you map textures on to it? How do you visualize it in real time? How do you work with it in a different program?

It isn't just tooling. > At render time, though, you need to use a bunch of extra tricks to get the right smoothing Nurbs or any smooth geometry needs to be subdivided too. You can set levels, max size of polygons, smoothness const

I'm not sure what you are trying to say here, constructive solid geometry does not solve any of the problems I mentioned and would have to be treated specially to be raytraced (while being likely being much slower). Converting it to po

Polygons can be smoother and subdivided efficiently at render time without artifacts, which is how they are used now. Nurbs and other curved surface representations end up with huge problems pragmatically when it comes to tools, workflow, v

tl;dr - a lot of mental energy going to avoiding making mistakes with indexed loops when iterators or macro that iterates but gives you an index inside the loop could be used.

It doesn't ignore that at all, the whole point is to move the heat from the tiny CPU to a big radiator with a lot of surface area. Air is a terrible conductor of heat compared to water, which pales in comparison to metal, but even met

Maybe there is a way to pull the raw image off before it gets bayer filtered. It would not be the same but might be closer to what you want since it would be higher res.

If you press your hand to the bottom of a heat sink and warm it up, then turn the water pump on, it feels like water just washed over your hand, the metal cools down as soon as the water passes over it. Some people seem to think air can be

It would be incredible if they could actually top what AMD has now and is planning in the future. I don't think there will be that same amount of room available to be able to blow away Zen 4 or whatever AMD will have by then. Jim Kell

gvim already handles this. If a file changes it prompts you to update or not. If you try to save an old file over a new one, it makes you confirm what you are doing.

A lot of times the problem actually comes down to not being able to find out what process is keeping a file open and/or not being able to close the process or file.
