Yes, issue with perspective exist, i mean because screen aspect changed from 3/4.
See MYgluPerspective in SetupGL function or some like that.
I don't struggle with that.

About modes - also increase your maximum of modes to 90, i think that be enough for every case.

Good luck with development.

[Korax]

Cool. I'll give that a shot.

Where can I find good textures for testing Hexen2's internal lump (LMP) 2D graphics... stuff like console background, console chars, statusbar, menus, etc.

I'd like to add external support for the internal gfx LMP files.

I'm not sure at all how possible it'll be to load-up Quake/Hexen2 data within the idTech2 engine, but I'll give it a shot when the time comes.

FTEQW loads quake 1, quake 2 and Hexen2... i think it's possible =) idtech2 got inventary like hexen2 maybe it's more compatible than we expect.

[Korax]

Thats true.

I've got another update that's almost done..
The way UQE's 2D scaling works has been improved significantly.

The current UQE you can just turn scale on/off and it will scale the 2D renderings either at their original size, or "fullscreen".

Some resolutions have this scaling create bad graphical artefacts... which I'm thinking was being referred to earlier.

The new scaling code works different... it still works only with on/off, but the engine chooses the best possible scaling for any given resolution (letterbox or wide) and scales accordingly with ZERO graphical artefacts.


EDIT:
Improved 2D scaling implemented!!
It calculates the current aspect ratio and resolution and scales the 2D graphics according to that for the best results with ZERO graphical anomalies.
Heres a screenshot of it in action on the hiest resolution I can set: 1920x1080

I fixed a few minor issues with the scaling code... at some cases it was giving me "bad coordinates" issue, but that was because I forgot to set the scaling (if its on) at video initialization.

Without the fix, all thats needed is to turn off the scaling cvar or start-up the game at 640x480 GL and it will turn the cvar off automatically.

Next on my list is experimenting with the "bloom" code.

Good news... "GL_ARB_texture_non_power_of_two" is implemented in UQE HexenII 1.14

Heres the results: (pay attention to the statusbar)

Before:


After:


The only thing I'm not sure of is mipmapping of model skins. Textures that are npow2 can't be loaded as-is if its going to be mipmaps. This means if I want the model skins to be unscaled (looks better) I can't get mipmaps for the model skins.

I'd like some inputs from the other developers in this.
My view is it must be scaled to make it pow2 because it must have mipmaps.

[jeank]

"My view is it must be scaled to make it pow2 because it must have mipmaps" - my opinion is same.

About resampling to pow2 - also use Lord Havok's texture lerp code, it work fine (i don't remember but believe similar code already implemented in UQE 1.13).

[WhiteMagicRaven]

Find in code GL_NEAREST and replace to GL_LINEAR to make hud looking smoothed, not point sampled. I dont know exactly but mipmaping for models ignored. always texture mode GL_Linear_mipmap_nearest???
----- for example in gl_draw.c
// point sample status bar
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); //raven: GL_NEAREST
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); //raven: GL_NEAREST
-----
also hexen2 in opengl shift textures after apply GL_LINEAR to status bar. you spot that one last line in image starts drawing bottom.
for easy look this

GL_linear filtered image (has true position)

Look Pa3pyX source code he fixed it. Or he makes it look closer.
Look at picture

[WhiteMagicRaven]

Apply GL_NPOT for everything look at Sickle this shoult looks less lined look

P.S. don't forget to read previous post )))

[Spike]

regarding hexen17.png - try clamping the texture coords to the edge of the texture:
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);

Boys, you are great in coding, i know...
i'm very happy because i started this thread and i see great results, but...
i'm still searching some skilled people to enhance the lightmaps and to create RTLIGHTS files... i'm not skilled in this way, but somebody can do it.
I'm sure.

It's not a joke: if we'll have RTLIGHTS in hexen2, coders will be incited to develop a better and performant graphic compart. And normalmaps will used at best

P.S. i saw a great idtech3 engine, that is relly promising: Xreal. find it on google and see it: that sources can inspire the coders in this thread

@Korax
Try to fix the "video modes" so user can change resolution INGAME...

[WhiteMagicRaven]

@Spike, This does not help, its maybe texture positioning.
EDIT
Plus i found some functions called SCRAPS that alter graphic.
If i disable it, some textures looks better and their coords proper.
What is it need to learn more.
How you fix zbuffer flickering? if we have two brushes with the same coordinates but with various textures game engine cant draw it, and we see flickering/ zbuffer fight.
?

2 MONTHS toghether!

This thread is 2 months old! we reached new objectives, and our visibility is global!

in this month:
- all the Hexen2 coders visited and posted here
- we got releases of Hexen2 engines discussed in this thread!
- coders are exchanging ideas
- textures are growing (i know, very slowly)

We are still searching RTLIGHTS experts...

[jeank]

We just do little steps now

I relax in that week, but today i start do something.
I made little tunes for jsH2 engine, replace some effect textures, fix some bugs.

May be soon i see about lighting system in jsh2.
For now i was test engine on old systems, and jsH2 successfully run on Voodoo 2 and Win9x.
In future i add new features unsupported by Win9x and old videosystems, so next build be last one fully compatible with old systems.

Screenshot: jsH2 with Inkub0 texture pack run on Voodoo 2

[inkub0]

interesting, but... is voodoo2 standard opengl? i guess no
