affine texture mapping, basically there's no floating point values, so if you want to set the vertx at a point between 1.0 and 2.0, it's gonna end up in 1.0 or 2.0 and never in between

It's called "perspective correct texture mapping" which apparently Saturn and playstation lack because it requires a division instruction per pixel, though some renderers would cheat a bit and only do a division every 8 pixels and then interpolate from there. This is why the SGI designed n64 was better.

nobody mentioned the n64.. but yeah, it wasn't better. they made up for it with poor draw distance and anti-aliasing hell using tiny little textures with fuck all colours. some perspective distortion is awful on the n64. have you ever played it before? it was released in the mid 90s, way before you were born. ;)

Kind of the same reason textures get bent along triangle edges on PS1.

The system doesn't really have the processing power to calculate texture alignments accurately, so it does some more simplistic calculations that will produce the right answer (or close to it) in most situations.

The saturn's solution to this is arguably better than the Playstation's was as the warping occurs less frequently and is even across the whole surface.

Saturn distorts across the quad

I'm still fairly sure this is because of the absence of floating point calculations, probably deliberately because they slow down the Saturn or because it doesn't support it in VDP2.

The Saturn version is an absolute abortion that never should have been made. Retarded control scheme, awful graphics, doesn't even run on the real Quake engine. The only port worth playing is the N64 version.

you what? Quake 64 is an awful, bland version of the game. N64 version somehow has less complex geometry then saturn version. at least saturn version has atmosphere. Controlwise the saturn works pretty well all things considered, can even use saturns 3d controller.

because textures are transformed without perspective. Only the cornerpoints of the triangle are moved on a 2d plane according to their 3d position relative to the camera. There is never real 3d like voxels would have. Even in modern games all 3d models are 2d sprites placed in a position relative to their 3d position on the flat camera 2d plane...

The difference to what modern graphic cards do is in modern "3d" transformations the pixels of the texture are distorted relative to the perspective making it look more 3d. Again this draws again a 2d sprite because monitors are 2d anyways.

But still voxels are still more 3d because every pixel on screen is rendered as a 3d position to the 2d position of the screen. And dont get me started on the possibilities for awesome physics if we had voxels and no shit polygons. Fuck nvidia, fuck radeon...

PS: If you dont understand do the following. Open a program like flash or photoshit. Place a rectangular photo on the stage. Cut it into two triangles (diagonal cut). Convert each triangle into a movieclip (flash). Set the transformation point for each triangle into one of the corners.
Now is where this starts what psx/saturn does:
You can now align this photo into any perspective grid. If you align it, ONLY USE SKEW, SCALE AND ROTATE, no other transform tool like perspective transform!. ONLY SKEW, SCALE and ROTATE.

If you now align the photo with some perspective lines you will see where the weird effect comes from.

Because flash is the best program, before adobe got it into its dirty claws, I made a quick video of what I just wrote.

Without getting into a Saturn vs. N64 pissing contest, the N64 version of quake is fantastic. I'd argue the more genuine level geometry and the fantastic Aubrey Hodges soundtrack mean Quake 64 has tons of atmosphere.

More importantly, the controls and physics run as smoothly as the PC version. I'm not saying the N64 version hasn't got downsides, but it's an excellent version of Quake.

The Saturn version is most impressive for pushing the limits of the Saturn. But, the ememy and player physics are all different which modifies the feel and the challenge. I'd love to play them side by side one day to get a real sense for it.

It's not just affine mapping. It's that despite talk of quads vs. tris the Saturn hardware really is deforming sprites, not texture mapped quads.

First, information. Most hardware when drawing polygons can't draw outside the framebuffer or it can but you don't want it to. Long story short you want to make sure that all your pixels will land inside of the display buffer. Let's talk about triangles on the PS1 first so you understand the normal case. So what happens when you've got a triangle with 1 of the 3 points outside the display? You have to clip it at the edge boundary. This results in a quad. You calculate the two new points that intersect with the display edge, then split the resulting quad into 2 triangles, however you also need to calculate new UV coords for the texture map because you aren't drawing from the same point. This is easy, trust me, it's easy. So you pass the two new triangles to the display hardware, it draws "in the lines" and everything is cool.

So what's the problem with the Saturn?

The first problem is quads. When 1 point of 4 is off screen you will clip to the edge and get a 5 sided polygon. The saturn can't render that but you also can't trivially turn it into 2 quads. It's 1 quad and a tri, so you can either force another cut to get 6 points which you can render as two quads or you can try and render a degenerate quad where 2 points overlap. This gets compounded when multiple points go outside different edges of the screen, you get lots of degenerate quads to deal with.

Second problem is you aren't really rendering texture mapped quads, you are distorting sprites from a reasonably flexible sprite buffer. You don't really have UV coords, you've got tile offsets. So if your clipped points need a UV of (2,3) you can't actually translate that to a valid value. The easy fix is to just round to the nearest, this means the texture will appear to slide around the clipped area frame to frame.

>> No.4631956

>>4631950
As with all hardware limitations, they can be mitigated somewhat. All games will exhibit this flaw to some degree, but just as good PS1 programmers implemented dynamic tessellation to minimise affine mapping errors, good Saturn developers implemented clever polygons clipping to ensure that the UV coord errors were only contained in the smallest possible degenerate cases that should stay away from the action as much as possible.

the advantage of 3d was new ways to play games most people had not until then. Kinda like the wii and the new weird nintendo handheld I cant remember the name of...

Overall, the amount of good games goes don't to the amount of games because making games gets harder with each generation. So less people can make games of that caliber and less care can taken care of gameplay because of all the other new additional factors...

Ammount of good games is the same today.
The technical aspect of the gamemaking eased up a lot, so we get a lot of low-effort shit, and the corporations fell into the trap of safe reiteration. However all other aspects of gamemaking like design, sound etc. remained mostly the same, so while ammount of shit increased, ammount of good stuff did not, but now you have to search a bit harder to find the good stuff.

I am sorry dude, but superprobotector is on an equal level like witcher3 for me. People just don't make superprobotectors anymore. Undertale, risk of rain all games I would not recommend less than witcher3.
TripleA games are easier for marketing. But the amount of work to quality ratio never can keep up if you ask me.
As I said the only feature of new tech is that it spawns new ways to play games. But devs run into a dead end, by raising graphics instead of staying at a comfortable level and instead making the gameplay better.
