can someone help me out with my rasterization routine?

code:

        //screenCoords[i] = vector between <(-1,1),(-1,1),(-1,1)>

        //Perform scaling. The screen is (-1,1) along the X and Y axes.
        float scaleFactor = 50.0f;
        screenCoords[i].x = screenCoords[i].x * scaleFactor + SCREEN_WIDTH/2;
        screenCoords[i].y = screenCoords[i].y * scaleFactor + SCREEN_HEIGHT/2;
    }

this obviously is the equivalent of a super-tight FOV. how i calculate 90-degree fov :saddowns:

e: oh wait that's a plus, so i'm wrong

e2: how far is the camera from the vector? Also what is this <(-1,1),(-1,1),(-1,1)>? three points in a plane?

e3: you mean a line segment from (-1, -1, -1) to (1, 1, 1) and the camera is at (-1, 1, 0) where points are (x, y, z)?

e4: regardless i'm p sure your scaleFactor needs to be multiplied by SCREEN_WIDTH and SCREEN_HEIGHT respectively (also be made like .2 or some poo poo in that case)

the screen is 320x200 so SCREEN_WIDTH and SCREEN_HEIGHT are 320 and 200 respectively

screenCoordinates is a vector containing an X and Y each between -1 and 1 which right now gets multiplied by a scale factor to produce pixel coordinates. the Z coordinate is for the Z-buffer.

the center of the screen is (0,0,0), this is well after we've done the camera transforms and everything

i might be doing this wrong

oh yeah at 3 am i figured out what i needed to do with that queue thing to maintain order without having some other thread read from the queue. everything in the queue gets a semaphore initialized to 0. everybody who wants to do the thing waits on the semaphore for their thing in the queue. whenever something's dequeued, it signals the next thing. and if the queue is empty, the next thing enqueued is immediately signaled. the end

this already exists, doesn't it

this is easier if you put the readers in a queue too

while next = blocking_list_of_stuff.pop {

worker = blocking_list_of_workers.pop
worker.process(next)

i'm doing a similar thing and the only class that looks related that i found so far is ConcurrentQueue

this really does seem like a class that would exist though so if anyone know what it is that would be very helpful

i don't even have any readers, even though i should. i think. idk. i just want multiple calls to this api from different threads or tasks maybe? to be executed in order

iirc (probably not) posix semaphores will make threads wait their turn but not .net

now this freaking httpclient is throwing 404s without even trying. i'm using mitmproxy to watch the traffic and it's just not happening. wtffffff

i must be holding onto some resource cuz the first request succeeds and then every request after that fails. hmm

# ? Jul 12, 2016 17:06

404 means it's not there, when i was debugging an API earlier it always meant the service was not running

ok so i'm benchmarking parallelizing this thing but the parallel version seems no faster (some runs were slower even)

it can definitely be slower depending on what you're parallelizing

lol i know what 404 means. i'm intercepting the traffic with mitmproxy (very good and cool) and the request isn't even going out! wtf!!

and i know the service is running because i am running it, on my computer. freaking microshafted again. it is impossible that my code is wrong.

fiddler required me to set a registry key and restart the app in order to do reverse proxy. lomarf. anyway i did already try that since mitmproxy's console ui only works (and poorly) in cygwin if you're on windows... but the same freakin thing! what gives!!

I heard they're researching whether git or mercurial will integrate better with our existing tools.

the answer is that mercurial is waaay easier for svn users to pick up and some of the third party tooling is similar

all the cool people use git though

really cool people have a special git config and workflow tools and they will talk about them

i'm going to be replacing a windows 2003 server that hosts nothing but an old version of visualsvn for a bunch of .net 4.0 programmers who use visual studio 2005/2008. as a computers janitor, do i want to suggest replacements to the developers for this product, or do i just want to drop in a newer version of visualsvn and have them take it from there?

# ? Jul 13, 2016 05:05

tef: May 30, 2004; -> some l-system crap ->

tbh, if you're moving olds from svn, hg is pretty ok and not a huge jump, the interface is very similar (you commit, but now you push and pull) and there's usually 1-1 mapping from one command to another

with git, well what you did in svn can be done in 20 different and arcane ways, but it does the job and ~everyone~ uses github or so i'm told

i've heard that to understand git, you should read some book "git from the ground up" or something like that.

to understand mercurial, i just had to read the manual.

of course everything everywhere uses git, so you need to learn it anyway.

a partner complained to me about using mercurial instead of git about 6 months ago in our company's projects. i told him that before i came to the company, there was no version control at all and the development and production server code had already started to drift apart quite significantly and mercurial was the one i could understand at the time. this happened in 2010
