Quake 2 on Falcon030

[LaurentS]

That worked. 'tis faster.

Prove it.

Hi all,

I'm not that sure that Doug has anything to prove to us. His skill level is far behond what we have on falcon for now.

Maybe something like : "Hey Doug, when will we have a new video that shows the improvement" or "when do you plan to spread the final version" would be more relevant.

Best regards,

Laurent

Hi Laurent - thanks for the support (!), but it was a friendly nudge from him in good humour as always

(But he's also right in a way - comments like 'its faster' hardly makes for interesting viewing!)

Best to both,
D.

[dml]

BTW before I forget... a big shout out to Joy & PARCP/USB - it's fantastic!

Oufff

The worse would be that some "irrelevant" people start to flame or troll you and generate a lake of motivation (we've already seen that so many times on forums).
But I should remember that here, we're between Atarist fans
to you all

So, Doug, CAN YOU PROVE IT NOW ?

Regards

Eerr.. the subject change trick didn't work!

shoggoth made many great stuff for Atari

(there should be some central directory of all ppl; past and ongoing project in atari world )

Amen! PARCP v4.0 beta changed my life!

Hey, nothing personal here : shoggoth
I'll have a look.

This could be a huge work to do

To dhedberg :

Have you managed to make more work on Willies adventure ? That was a very promising game.

Cheers all

Laurent

Amen! PARCP v4.0 beta changed my life!

And I heard that your influence is making it even better

You won't need to look far - its the PeP!

So the last experiment I did was to retrofit the BadMooD colour quantizer into the Q2 engine and generate palettized versions of the 24bit colour lightmaps hiding in the BSP files. With some mods to the surface cache the Falcon can now render with coloured radiosity lighting!

There are at least two caveats though:

- lightmap bilinear filtering doesn't work with this approach, so the lighting gets quite blocky in places, especially where there are hard edges in the lightmaps
- dynamic lights would require at least one extra indirection to combine them so this would be a performance question mark (esp. since a mono version isn't even working yet)

I suspect by loading the quantized lightmap palette onto the DSP it will be possible to do some or all of this quickly with less lookup/translation and maybe also do filtering for free. But I'm not sure yet - and probably a lot of work. For now its just a basic experiment to see colour (hardware GL!) radiosity lighting on the Falcon

I'm quite busy today but will get some of last night's screenshots up when I get time for it.

These screenies were taken from the Falcon build using colour lighting. This demonstrates the most significant difference between Q1 and Q2 map formats, since Q1 maps only encoded mono lighting data.

Performance is much the same as with mono lighting (for now) but as mentioned above, filtering/softening of lightmaps doesn't work and I don't yet have a sensible way to combine dynamic coloured lights. It also uses a bit more ram.

As a test it looks nice on the old Falcon, at least for a software renderer Normally you only see this mode with OpenGL!

Amazing! Especially when it starts moving...

[EvilFranky]

Holy crap that looks great!

[Scarlettkitten]

Wowzers, nice.

I love the textures from the map with the eyes on the wall, I've not seen that level before, looks very aztec / egyptian style.

That one is a homebrew DM map - there are lots of really nice designs by experienced mapbuilders in the Quake community (although I can only load some of them currently - still problems to fix and wasting a bit too much ram).

It's partly the sheer number of available maps - and tools and guides to build them, as with Doom - that made this project a bit more interesting to try.

[dml]

Amazing! Especially when it starts moving...

I'll probably not make another video until:

- the sky starts working properly. still some annoying stuff to fix there.
- the special surfaces e.g. water, light panels start working properly.
- polygon rate is improved
- dreaded sparkles are cleaned up a bit

This will take some time, but stay tuned

Beauuutiiful!

[shoggoth]

Shat!

[calimero]

this is fornicating amazing!

I am not sure how you manage to get same speed as mono lighting but this screen shot are more than amazing!!

[dml]

Shat!

check one!
