Ruining the classics (screenshot heavy thread)

Ahruman, I'm having a bit of a problem with the shader bindings, specifically a heat glow effect tied to engine_level, you mentioned in this thread https://bb.oolite.space/viewtopic.ph ... c&start=15 that you were removing the old way of accessing engine_level for the new bindings, so i've been browsing the wiki and decided to use "flightSpeed" instead, but i'm not seeing the effect in game. i've tested out the shader in rendermonkey and it seems to be ok:-

and if i change the enginepower binding in the shipdata.plist to "timeElapsedSinceSpawn" i'm seeing the shader effect ingame:-

is the flightSpeed property not providing high enough values to drive the shader effect? is there another bindable property reference i should be using instead?

edit: sorry, all the stuff about enginepower wasn't very clear, what i mean is, in the shaders part of the ship data.plist i have:-

Code: Select all

uniforms = 
  { 
     time = "universalTime"; 
     enginepower = "flightSpeed";
   };

and in the fragment shader, i have

Code: Select all


uniform float         time;
uniform float         enginepower;

have i got that right?

speedFactor. flightSpeed should be giving too-high values. (The lists on the wiki page could probably do with a bit of reorganizing…)

Looks right.

Cheers for the help Ahruman, it's still not working though even with the speedFactor binding.
i've tried giving the "boa" fuel injectors and various values of max_flight_speed in it's shipdata.plist but then effect never appears even with it whizzing along faster than my supercobra! it's like the value being passed from oolite to the shader always stays at 0.00000 except for when using the timeElapsedSinceSpawn binding, it works OK when that is used, although in the fragment shader i had to multiply the value by 0.01 so that in-game it gave me enough time to launch and get to the ship to check the shader was increasing the glow effect over time as otherwise it would get to it's maxium glow level of 1.0 in about a second!

as an experiment, i've also tried the following bindings energy, maxEnergy, mass, flightPitch, flightRoll and even though i've been chasing it all around the system none of these bindings have got the shader working either although it did attract a lot of vipers!

Almost exactly a second, in fact. :-)

Set $shaderDebug to on in logcontrol.plist and check the log. If this doesn’t tell you anything, e-mail me what you’ve got.

Edit: sorry, first time i posted the log i had the glowing_alloy oxp installed which had it's own shaders appearing in the debug report, i've removed them nowq and reposted the debug log with only the problematic griff_boa.oxp installed.

It tells me two things:
1) The uniforms you’re setting up (engine_power = speedFactor, time = universalTime) are being bound properly. They ought to be working. :-/
2) The support for legacy non-bound uniforms that was supposed to be in 1.69/1.69.1 isn’t actually working, because the syntax in material-defaults.plist is wrong. Oh, well.

I've uploaded the griff_boa.oxp here:-
http://www.box.net/shared/eipirjmmp8 (4.1MB)
blimey! 4.1MB for 1 ship.

Edit: here's a more optimised version created following ahrumans advice (a few posts below)
http://www.box.net/shared/4rm3dqsclr 1.3MB

If you're on windows and have directx9.0 and a shader supporting graphics card installed I've included a resources folder in the zip file with all the files needed and a quick quide on how to load in the models & shaders from this oxp into rendermonkey and how to swap out the textures and models for your own designs.

No worries about the shader bindings Ahruman. although i did notice that if the shipdata.plist is in OpenStep format the ship's turrets didn't work properly in that they were often pointing in odd directions and firing off the occasional potshot at nothing at all, having the shipdata.plist in xml made them much more aggressive and accurate, i've put both format .plists in a folder in the download if you want to check - possible somethingi've done wrong with the initialiseTurret setup_action in the openstep format .plist?

Edit: forgot to mention it's a non-player ship ship, plus it's stupidly sized at the moment, the plan is to have it park outside stations and use smaller ships to ferry cargo onboard them.

The title of this thread is misleading!

Don’t say silly things like that. :-) These things won’t fix themselves. Turns out that shader uniforms in subentities weren’t being bound to the parent entity as intended (now fixed).

It appears to be because no thrust is specified in the OpenStep version. Thrustless objects can’t turn, so the turrets can’t track. (They maintain an absolute orientation; really ought to be parent-relative, but that could be complicated.)

BTW, I like the skull. :-)

A problem with this ship is load time. This is what happens when you use a dozen textures for one ship.

An easyish fix to this is, well, use fewer textures. (This will also save on texture memory.) This can be done by using channels that are currently unused. For example, you could put the specular intensity for griff_boa_illuminated_subents.fragment into the alpha channel of griff_boa_illuminated_subents_diffuse.png, hard-code the specular exponent (which is constant), chuck out one texture and still have a channel to spare:

Code: Select all

   vec4 colorMap = texture2D(tex0, texCoord);
   vec4 glowMapFullOn = texture2D(tex1, texCoord);

   float specExponent = 2.12; // pow(2, (39/255) * 8) = 21.2235
   float specIntensity = colorMap.a * 1.5;
   colorMap.a = 1.0; // no transparency

This would also increase efficiency – the pow() calculation, texture lookup, and binding of a third texture unit all cost.

Similarly, you could merge griff_boa_subents_specular.png and griff_boa_turrets_specular.png by using the b and a channels for one of the shaders.

I don't want to ruin a perfectly good model, but unless you are actually going to put working turrets on the ship, shouldn't these be removed? Unless they are nonfunctional on a rusty ship or such.

Griff · Post by **Griff** » Fri Aug 10, 2007 10:14 am

that's odd, the turrets should be working, they're not in the screen shot i posted a few posts back (the quaternions were giving me problems) but they should be in the version i put up for download... there was a problem with me not giving the turrets a 'thrust' value in their shipdata.plist, ahruman pointed out that this stopped them from being able to track targets but i thought i'd fixed that. there's no turrets on the front and underside of the ship so it can't get you if you hide there, try popping around the back and fire a few lasers into it's engines.

i seriously need to scale down the 1024x1024 texture and merge some of the effects maps together, i totally didn't realise we could use the alpha channel as well *studies photoshop help files to find out how to use the alphachanel* i think i might remove the specular exponent maps and just give it a fixed value in the shader, i'm not really using it much and it's taking up space.
i'll change the pow calculation to the other example you posted in the shaders outpost thread ahruman, the quadratic curve, you did warn that the pow one was expensive to use, i forgot to change it when saving out the final fragment shaders from rendermonkey.
