Luigi Thirty: Apr 30, 2006; Emergency confection port.

i'm so stupid i've been trying to figure out perspective-correct texture mapping forever. i can't figure out where the Z fits into the formula. who's smarter than me and knows how to go from this working affine mapping function to perspective mapping?

code:

if((screen_x >= 0 && screen_x < SCREEN_WIDTH && screen_y >= 0 && screen_y < SCREEN_HEIGHT)){
                float z = triangle.solve_plane_for_z(Point(screen_x, screen_y));

                //texture: X = U, Y = V, Z = W.
                Vector3f barycentric = barycentric_point(screenPoints[0], screenPoints[1], screenPoints[2], Point(screen_x, screen_y));
                float w_prime = barycentric.x + barycentric.y + barycentric.z;
                int u_prime = (int)(((barycentric.x * triangle.texturePoints[0].x + barycentric.y * triangle.texturePoints[1].x + barycentric.z * triangle.texturePoints[2].x) / w_prime) * 256);
                int v_prime = (int)(((barycentric.x * triangle.texturePoints[0].y + barycentric.y * triangle.texturePoints[1].y + barycentric.z * triangle.texturePoints[2].y) / w_prime) * 256);
                color = checkerboardTexture[u_prime + (v_prime*256)];

                if(z < zbuffer[PIXEL_OFFSET(screen_x, screen_y)]){
                    assert(screen_x <= 319 && screen_y <= 199);
                    zbuffer[PIXEL_OFFSET(screen_x, screen_y)] = z;
                    setPixel(pixels, screen_x, screen_y, color);
                }
            }

i don't "get" people griping about the gpl. like, what do you care how other people's code is licensed? you want to write some software that does a thing, go right ahead, no one is stopping you, open up notepad.exe and get started.

It's like complaining that you're not allowed to use microsoft's source code they wrote for edge. it's not yours, you have no right to it.

I have no idea but shouldn't w_prime be always 1 because that's the definition barycentric coordinates?

hypothetically, if $corporation likes your gpl library and wants to use it in a closed-source project, you can offer to grant them a separate commercial license to the library for a price

$corporation can USE AND MODIFY your GPL library all they want for their internal applications. it's if they want to DISTRIBUTE their applications that they have to either distribute them under the GPL or get a separate commercial license from you.

Barycentric just mean the coords are in relationship to the vertices of the triangle. It makes no assumptions about inside or outside. So w_prime could be anything depending on where the point is in relation to that triangle.

Also, due to floating point being an approximation, I doubt w_prime is actually 1.0 very often even for points that are definitely inside the triangle.

            }

according to the tinyrenderer thing, to account for the perspective transform, you need to calculate the triangle's barycentric coordinates in clip space and then use those barycentric coordinates to interpolate textures for your fragments/pixels

don't use the screen space barycentric coordinates

our internal SSO has been broken for 3 days and breaks at least once a week for a semi extended period of time in our dev environments.

the team that manages it doesnt seem to have any alerting or anything because every time it goes down i need to ping them in their channel and then they'll act like i'm stupid until someone realizes it's actually broken.

getting really goddamn frustrated.

internally everyone does use Kerberos, but externally you have to use SAML or ws-federation or, worst case, oauth2. and those are difficult for some types of people

yeah sorry I wasn't clear. by 'internal' i meant 'our development instance of sso.' we of course use kerb for our internal sso.

it's kind of a tricky thing because of course the SSO team needs to have a development instance that they can test against, but if it goes down my team basically cant work. i can work around the outage in my dev environment but it also breaks other internal services i depend on, and i cant work around that. not always, anyhow, of course it depends on what i'm doing.

i'm rallying for some sort of 'dev sso environment that is only updated after sso changes have been pushed to production' but there's also the issue that sso sometimes goes down because its own dependencies are breaking, so all those people need to get on board too.

my boss has been talking to their manager to figure out wtf is going on but nothing useful has come from that yet

theres no reason for a separate dev Kerberos environment. just use your existing domain everywhere.

i have no idea how everything works. the thing that's broken is the service we use to generate an sso ticket for a user. whether this is actually connecting to a different sso environment is unknown / irrelevant to me.
