This implementation has a flaw: editor displays curve (x(t), y(t)), but animation engine uses it as (t, y(t)). Essentially, during "animation" we assume that dx/dt = 1, but it is not the case for bezier curve we're drawing (one can note that projections of dots onto horizontal axis have different density).

@@Czeckie I did this: while (Math.abs(p_next.x - target_x) > threshold) { while ((p_next.x - target_x) > threshold) { t -= step p_next = c_bezier(t, p1, p2, p3, p4) } while ((p_next.x - target_x) < -threshold) { t += step p_next = c_bezier(t, p1, p2, p3, p4) } step *= 0.1 } Pretty sure that's neither "technically correct" nor fast, but it sure looks convincing enough! Assumes the x coordinates of the points are increasing though.

For Tsoding (If he still didn't find the answer himself) and others: About Inkscape being light: the setting is per document. Every time you open a new document, it creates a copy of the "default document", so to change the default background, edit the default document. About the const local variables being able to be used in static variables, apparently (Just learned this) it is because static variables that are LOCAL to the function, even though static, are initialized the first time the function is called (I have no idea how that's implemented, does it generate a flag and initializes when the value is not set or something?). You also should be able to do that at global level, but it didn't work because Tsoding trying to create an array of dynamic size, not dynamic initialization. Dynamically sized arrays are not allowed in statics, even local.
@hwstar94164 ай бұрын
I think it's a gcc extension. tried it with msvc and tcc and didn't work. I think static is initialized at startup not when function called for the first time.
@Daniikk10124 ай бұрын
@@hwstar9416my bad, the standard does specify that statics are initalized at startup, before main (I was confused because in C++, they are guaranteed to be initialized the first time the function is called), so it seems to be an extension. What's weird is that it works even with -ansi -Wall -Wextra -pedantic, which SHOULD turn all extensions off.

Theoretically telling, C is Turing Complete, so it can do. Practically telling, it's made in Quake 3 source code. Most of curved surfaces in game are based on Bezier curves (they're called "Patches"). These are used in many other games, including Doom 3 and Xonotic.

you can cast a function pointer to void* just fine in iso c (c99 onwards at least) but you have to do the cast explicitly like `(void*)func` as for static arrays requiering comptime initialization I have no idea why that doesn't work for array sizes (maybe the compiler is interpreting it as a variable size array based on passing an ident associated with a variable even tho it's comptime known?) also c23 introduces constexpr which should just work as expected
@ovi13264 ай бұрын
Also it's defined behaviour to take a typed pointer convert it into a void* and cast it back to the same type, vtables in wasm work the same way they do in x86. Now taking a function pointer casting it to void* and then casting it to char* to read the assembly is undefined behaviour.

@@thebatchicle3429That could be the case but usually the function pointers are either the same size or smaller than data pointers (like in the early days of wasm64, I did a quick search and wasn't able to find any other platform that did thay). And it's defined behaviour to cast UINT32_MAX to size_t and then back to uint32_t, there is no way overflow would happen.

You know, just reading the chat comments can be hilarious sometimes. Like the people arguing over compiler implementations and pushing to answer a question that's answered in the standard document by looking at implementations which may not be relevant to their own usage anyway. Compiler Explorer and speed up certain testing, but no compiler should be used as a replacement for reading what it says in the actual standard. I still don't get why so many people have problems with accidental assignments in conditionals because the majority of the time you're not testing for flat equality, but then I also don't make such mistakes when writing code even when using flat equality tests. Although, towards that end in my own language, I did make it so that simple assignment in a conditional isn't possible with just = and you'd need to use := to force an assignment. I definitely agree that mathematicians using complex formulae with "unreadable" symbols is gatekeeping. I haven't used much complex math in my career, but what I have used was much easier to understand when written as code than as a squiggly formula. One final thought I had regarding hot reloading and v-tables is that the method that most implementations aim for is an optimization technique and given when C++ was first developed it makes sense because even at millions of function calls on the older hardware that it would've been run on, it's possibly too much to ask of the hardware. However, in the current day, they probably should use the indexing method because even at billions of calls it's still relatively speedy and allows for hot reloading.

10:00 I respect you very much, but I have to disagree: the complexity of mathematical language is not due to gate keeping. That's like saying APL or C++ are gate-keeping languages. I think, if you had to reboot mathematics as a green-field project, starting from set-theory (or some other fundamental basis) and work your way to algebraic and differential geometry, combinatorics and statistics, you'd end up with something just as scary looking. I think every programmer has done that thing where we look at a solution, say 'that's way too complicated, I can do it better', then we dig into it, see all of the edge and corner cases and 6 months later we have almost identical code to the original and find ourselves saying "oh, now I see why it was done like that."
