ENIGMA Development Environment

What screen resolution are you viewing this on ?
I think this has to do with scaling.

I have done tests using game room 1:1 with screen res, (no scaling) and they display fine,
also at monitor's native resolution, evenly spaced and fine.

Very confused here, Robert seems to suggest that everyone complains when offsets are present, and that I am the only one having issues with or without offsets, so by that I am to understand that nobody has any issues with fonts.  I find that really difficult to digest because I tried this shit on different systems and all behaved the same way.

My current system this shit was tested on:
Intel i5-3570k
16GB RAM Windows 7 64bit
EVGA GeForce GTX 660 Ti SC 2GB
Drivers 337.88 WHQL (NVIDIA)
----------------------------------------
My other older system I tried the same project on,
as you can see major differences between hardware
AMD Athlon X2 6400
2GB RAM Windows XP SP3
BFG GeForce 8800GTS 320 MB
Very old forceware drivers

2 completely different systems, same bloody display, same exact thing, identically displayed.

2 different chipsets, CPUs, grpahic cards, OS, so this rules out that anything is wrong with my system !!!

Robert, your latest suggestions didn't give me results, only worse:

float xoff = 0.5 / texture_get_width(fnt->texture),
        yoff = 0.5 / texture_get_height(fnt->texture);
draw_vertex_texture(xx + g->x,  yy + g->y, round((g->tx + xoff) * 100) / 100, round((g->ty + yoff) * 100) / 100);
draw_vertex_texture(xx + g->x2, yy + g->y, round((g->tx2 + xoff) * 100) / 100, round((g->ty + yoff) * 100) / 100);
draw_vertex_texture(xx + g->x,  yy + g->y2, round((g->tx + xoff) * 100) / 100,  round((g->ty2 + yoff) * 100) / 100);
draw_vertex_texture(xx + g->x2, yy + g->y2, round((g->tx2 + xoff) * 100) / 100, round((g->ty2 + yoff)* 100) / 100);

and


float xoff = 0.5 / texture_get_width(fnt->texture),
        yoff = 0.5 / texture_get_height(fnt->texture);
draw_vertex_texture(xx + g->x,  yy + g->y, g->tx + xoff, g->ty + yoff);
draw_vertex_texture(xx + g->x2, yy + g->y, g->tx2 + xoff, g->ty + yoff);
draw_vertex_texture(xx + g->x,  yy + g->y2, g->tx + xoff,  g->ty2 + yoff);
draw_vertex_texture(xx + g->x2, yy + g->y2, g->tx2 + xoff, g->ty2 + yoff);

Text is not rendered at all, nothing is shown.

float xoff = 0.5 / texture_get_width(fnt->texture),
        yoff = 0.5 / texture_get_height(fnt->texture);
draw_vertex_texture(xx + g->x,  yy + g->y, round((g->tx + xoff) * 100) / 100, round((g->ty + yoff) * 100) / 100);
draw_vertex_texture(xx + g->x2, yy + g->y, round((g->tx2 - xoff) * 100) / 100, round((g->ty + yoff) * 100) / 100);
draw_vertex_texture(xx + g->x,  yy + g->y2, round((g->tx + xoff) * 100) / 100,  round((g->ty2 - yoff) * 100) / 100);
draw_vertex_texture(xx + g->x2, yy + g->y2, round((g->tx2 - xoff) * 100) / 100, round((g->ty2 - yoff)* 100) / 100);

and

float xoff = 0.5 / texture_get_width(fnt->texture),
        yoff = 0.5 / texture_get_height(fnt->texture);
draw_vertex_texture(xx + g->x,  yy + g->y, g->tx + xoff, g->ty + yoff);
draw_vertex_texture(xx + g->x2, yy + g->y, g->tx2 - xoff, g->ty + yoff);
draw_vertex_texture(xx + g->x,  yy + g->y2, g->tx + xoff,  g->ty2 - yoff);
draw_vertex_texture(xx + g->x2, yy + g->y2, g->tx2 - xoff, g->ty2 - yoff);

Text completely distorted mess.  Here is an example, ignore blurriness again, the postimage hosting somehow
completely messes up the image quality.  The edges are razor sharp otherwise originally.

This seems to me be perfect Runes fonts ! What's the problem ?    

http://en.wikipedia.org/wiki/Runes

Right FUNNY.

Trust me, these are 11111111111's you should be seeing !
The same when compiled using DX9 displays fine.

lol, thanks, I've done all the first ones you suggested I will call it a night and work on the rest tomorrow.
BTW, this still is not a 100% fix, and a band aid, as there is something somewhere causing this, again this is just seems to shift things much like when I played with the projection ortho and GL MODEL VIEW offsets before

So anyhow,
1) if I understood your comment to me, you are telling me that with offsets 0.00/0.00 for BOTH projection ortho and GL VIEW your text displays fine and no scrolling glitch right ?

2) With round on all vertices with 1000, it solves the problem for window and full screen with default font and size so far across all screen resolutions I tested, from 320x200 ~ 1920x1080 (my native) hoping I did not miss anything.

However, when I tried different fonts and sizes I saw some vertical lines / dots on some letters / numbers, even when big.  Also there are other font glitches one might notice, if using too small fonts and certain screen resolutions, this is NOT an ENIGMA problem and so is up to the developer to use the appropriate size fonts for their game size.  but the lines, dots, etc those influenced by ENIGMA.

So finally after trial and error I found that with the combination of round 1000 across the board and the default font, things work great.  If using declared fonts, it is recommended using no smaller than 14 px, and using aa 1.  I found that with min 14 font size and above + 1 aa worked fine for me across all resolutions, window / full screen and tried different fonts.

So here are the changes I have done :
GSFont.cpp
draw_vertex_texture(xx + g->x,  yy + g->y, round(g->tx * 1000) / 1000, round(g->ty * 1000) / 1000);
draw_vertex_texture(xx + g->x2, yy + g->y, round(g->tx2 * 1000) / 1000, round(g->ty * 1000) / 1000);
draw_vertex_texture(xx + g->x,  yy + g->y2, round(g->tx * 1000) / 1000,  round(g->ty2 * 1000) / 1000);
draw_vertex_texture(xx + g->x2, yy + g->y2, round(g->tx2 * 1000) / 1000, round(g->ty2 * 1000) / 1000);

Also, these changes apply for the default halign left and valign top.  Whatever is decided to be used, we'll have to change the other vertice for the others.

Will try the rest tomorrow.

See if you are ok with the changes above Robert and that they work for you.  I'm ok with this for now until we find a permanent fix.

Thanks.

My only complaint with ENIGMA is the fact that it is sexually confused.

Do elaborate !

Anyway I am thinking of keeping the object resource for my spinoff and allowing sources and headers to be added with a simplification of the instance system allowing it to be easily coded giving you more control.

I am not sure if any of my ideas will come to fruition or not.

How long do you think this could take you ?  I've mentioned minimum 2+ years and that is being generous.  How long do you expect to do this, alone........  If you can pull this off, then someone should sign you up right away and hire you !

I know of another project that was crowd funded, has an entire team and years later they still are working on it.  So how the bloody hell are you going to pull this off anyway, alone when you mentioned you barely have time to take care of ENIGMA ?

Either way, I am always willing to try something new and will be glad to take your new engine for a spin when it's done, assuming it's done on time before the end times

I know that, and I don't care, I want to know if the fonts do the same shit to you in windowed mode. If you have any sort of intuition as to whether Direct3D exhibits this, because it only had blurry text for me.

I will have to check again with DX9 will let you know.

The reason I mention is because when interpolation is on it does the same thing your fonts are doing now, because interpolation is on and all the characters are right next to each other on the texture, they interpolate into each other along their border, which causes similar artifacts to the ones you are describing. We also plan on fixing this by adding padding options to the font packer.

Ahh yes good point indeed, but I can assure you interpolation has always been off. BTW when I had this font issue that is the first thing I checked.

One thing to note, I use the 11111111111111 as example,
not all 1's have artifacts as I explained.  Wouldn't interpolation or vertex changing have an effect on all the 1's ? Why am I seeing those artifacts only on some 1's and not all ? I am using 1 as an example, but I tried with all the letters range and numbers, same, sometimes the lines are on top or bottom of letter or dots.

It was NEVER mentioned by me that my fonts are blurry in ENIGMA.
I had complained about that about GM and GMS, many have, they seem to use an alternate method of scaling.  I rather see stair stepped fonts (upscale) than ugly blurry fonts.  That has never been an issue for me in ENIGMA.  But I don't recall ever seeing the artifacts in GM:S either.    You are telling me that it is my hardware......  I would like for other people who have NVIDIA cards to test files I will upload soon, and more people with different cards.   BTW I will mention that no matter all offsets I have worked with none produced blurry fonts, only artifacts changed position
but fonts remained crisp throughout the entire ranges of offsets.

Which it has to be because the overdraw in your characters is obviously coming from the other characters on the texture.

But how would it explain that the artifacts are not unfirm on all characters?  Example if I were to use 1111111111111111111, not ALL the 1's would have the verticle line next to the 1, in fact most would be displayed ok but 1 in some offsets, in other offsets every 2nd 1 would have artifacts, etc.

Just to reaffirm, you have been having these vertical bar problems with fonts since you first used ENIGMA?

Good question.  I don't really recall seeing this when I first started using ENIGMA, but then again, I did not use text that much. and did not use full screen as much either.

The first time I ever noticed this glitch was with the image alpha project experiment where I was displaying text on the screen, this is the first time I accidentally stumbled on it. and reported the 1 being displayed weirdly.

Should I try downloading early revisions of ENIGMA and testing ?

No it was the same way on my old AMD card.

The real problem here Darkstar, there's very little information on fixing half pixel alignment. I'm still confused as to whether or not you even have blurry text or if these offsets are fixing the bars on font characters.

Everytime I open this topic I want to cry.

I submitted every info I have, please re-read the entire topic
I uploaded a couple of screen shots to show you exactly what I mean.  Blur is not and has never been a problem, I showed you exactly what I mean by text problem, they are artifacts (small lines / dots around text) look at the screenshots I posted in this topic and you will see.

The offsets are indeed shifting out of view the lines next to text.
That's why I kept telling you the problem is not pixel alignment in regards to blur, but just so happens the fixes work because it is offsetting the artifacts out of view, maybe the real problem is in the fonts system / renderer ? Maybe something else can fix it I don't know.
Go check my screenshots I magnified and made it so big you will understand what I mean if you had seen them
