nice speed! ^^ MAybe you should zoom back a bit so when rotating the feet are still inside of the pictore (as triangles that are partially outside of the screen aren't displayed) ^^

If you reduced it to half or 1/3 the size (as it ould be needed for games) and also reduced teh quality of the model (noone notices at that resolution) it should run really smooth *-*

Yeah that was to show off that culling work at custom resolution

Anyway, a game could be doable even at 320x240, and that what game should aim for, cause halfscreen doesn't look *that* good. But anyway, those are way much bigger model than a game should contains

(1700 polygons is waaaaay too much)

EDIT : some nice debugging screen

Lol actually at first I thought it was some sort of shading changing effect XD. It actually looks cool

That looks AWESOME!!

But I guess that's at full rendering speed...? >.<
It would be really cool if you could make her appear like that and then start doing some fancy fight moves or something like that

Nah it is slowdown by a halt somewhere in the texturing setup, since this model render without halt at more than 2fps

Animation would be a cool addition, altough I am still figuring how to do that proprely

you have to make chewing cows *-* they look great

u/TheMachine02 October 20, 2016, 03:02:23 PM

So several update of the texture code. First it use exx, so don't expect perfect timed interrupts when you use it

Second, it is faster. Like x1.5 to x2 faster :

And third, it support texture up to 255x255 shamelessly :

Of course, 255x255 will be hardly usefull in pratice, but who know

(And anyway, it was a consequence of optimization and algorithm making)

Darn, so many details. :O

u/c4ooo October 20, 2016, 08:07:53 PM

As amazing as it looks, it would nice if you where to provide more practical demos that ran at better FPS

u/p2 October 20, 2016, 09:05:45 PM

or maybe also stick to one model and create a comparison post to directly see the imrpovements/changes you have made?

That would be nice

I'm definitively curious about how fast would 16 arwings rotate, in frames per second. And by arwing I mean the SNES ones, for less polygons and no texture.

u/TheMachine02 October 27, 2016, 08:18:54 PM

Well, I don't have the original snes model, but by lurking around on the net, I found an average polygon count of ~30 triangles. So, 16 times this model would be less triangle than the high poly (629 tri) chocobo posted earlier in the thread, and would run even faster (so >12 fps) (and with depthsorting). Of course this a bit speculation, but it should be fairly correct.

I don't think you are going to need 16 of those on-screen in a game situation though? So the performance might be better in reality.

That being said, if they are too close to the camera it could be a drain

.

Looks AWESOME btw @TheMachine02 !

u/TheMachine02 October 28, 2016, 03:05:26 PM

So just wanted to try that one day. Sure it is quite broken (ie, converter broke uv coordinate), no bfc cause broken too, and no cliping, but still cool

[spoiler]

[/spoiler]

And yeah, a strafox is more than doable. Just need to get on it one day

I said 16 in case someone made a Star Fox clone with an Area 6 style stage where there could easily be that many enemies at once on the screen actually
