Socracheese posted:i want to dabble with the nvidia parallel computing library but i dont have any big processing problems to solve there are two "popular" lovely wifi protocols. one is WEP, attacks on which are bottlenecked by how fast you can gather relevant packets. the other is WPA w/ WPS, and that's limited by how powerful/stupid the router you're trying break is. the only relevant-to-your-interests, computationally-limited attack is good ol' brute forcing the pw. for that, you've been beaten to the punch: pyrit does it on the gpu already, which for WPA tops out at 110k pw/sec on latest-gen AMD hardware. even then, you'll only get lucky if your neighbour's have picked a lovely dictionary-based password. don't let this put you off though, it'd still be hella instructive for you to write your own. coffeetable fucked around with this message at 17:25 on Sep 6, 2013 |

oqb don't bother with speed right now, doing what your doing is a v good way to learn how 3d rendering works and when you reach the point where you want it to be fast just switch to using opengl and shaders. with what you learned by doing it all by hand it shouldn't be hard

what i've learned today: -rotation is easy -subdividing a triangle is easy although i have to write some sort of "3d object" class with a list of vertices and triangles so that i can do it properly (i.e. subdividing every triangle into 4 instead of 3 - adjacent triangles need to share the new vertices so i can't do this as just a list of unrelated triangles) -z buffers are like black magic and i apparently have no idea how to code one (right now it's sorting by midpoint distance which kind of works a little bit but not really) https://www.youtube.com/watch?v=8AakDr0R7mI ol qwerty bastard fucked around with this message at 18:42 on Sep 10, 2013 |

ol qwerty bastard posted:what i've learned today: you can get the normal vector by picking two vectors along two edges of the triangle and doing a cross product. however it means that you need to mind the vertex order of your triangles so that their normals face outwards. you'll want to do that when you decide to do lighting anyway but triangle sorting is kinda messy and you need to avoid having too big triangles to limit the cases where they end up sorted badly zbuffer is simple: for each pixel of the screen, you store the nearest distance (ie Z) at which you have previously drawn a point from another triangle on it. you initialize it with a max distance value before rendering your frame. when you rasterize a triangle, for each pixel you calculate its distance (simply by interpolating the z coordinates of the vertices, assuming they are already transformed into camera space), and if the pixel you want to draw is closer to the camera than the one you drawn previously, you draw it and store its z value in the z buffer, otherwise you ignore that pixel. you also ignore that pixel if its z value is out of range for the z buffer (which means you need to pick some arbitrary min and max draw distances)

Zlodo posted:you can get better results with triangle sorting by doing backface culling: basically dont draw triangles whose normal vector is facing away from the camera (if your object is convex this will actually render it correctly without needing sorting or z buffering). ah yeah i'd forgotten to do the backface culling thing; i even already have the code set up so it automatically generates a unit normal vector when the triangle is instantiated. i was using it for lighting but it'd be straightforward to tell it to dot with the camera vector and then if it's negative don't render i was definitely finding that triangle sorting is messy; i dread the day when i try to write code that will allow two intersecting triangles to render correctly i guess i need to write my own draw_triangle() code to do proper zbuffering if i have to do a pixel-level thing on it though; currently i'm just using the pygame.draw.polygon thing. ah well, that shouldn't be too hard

Cold on a Cob posted:i thought it was not really racist at all b/c they basically said the white man "won" via right place, right time. but i guess diamond also doesn't really talk about china, etc. i could be mixing it up with other books though like 1491 here is guns, germs and steel in a paragraph 'eurasian peoples were much better positioned to develop advanced civilizations, not because of any kind of racial differences, but because their continent was oriented east-west, allowing long-range transmission of domesticated crops & animals within a similar climate band. why did europe end up controlling the world instead of china/india? gently caress if I know lol' (he added a half-assed afterword in one edition suggesting 'china was centralized, india was decentralized, maybe europe was just the right mix of centralization & disparate small states to make progress????' it's the dumbest thing and so of course 'business leaders' ate it up) anyway I get the feeling that a lot of the people who criticize guns germs & steel are basically jealous of its success/popularity and/or his dismissal of touchy-feely 'intellectual factors' (i.e. either 'great men' theory or 'THE ESSENTIAL WESTERN VALUES OF FREEDOM'). most of his theses seem pretty solid - there are some issues with grains (domesticatable grains were more widely available & more easily spread than diamond thought), but the theory as a whole seems to hold up pretty well anyway that's me replying to week-old posts current spare time project status: considering open-sourcing it so people can look and tell me how bad my code is. not like I'm planning to make any money off it anyway.
