Anyway it looks VERY cool

I wouldn't mind adding a five-frame animation. I'll have to do that on Monday, though. Busy weekend, and this area of the world is in for a foot of snow.

how on earth did i manage to do a 5 frame animation and fit it into a power of 2 scale image? i think when i was working it out i just assumed that as each frame was 256 x 256 pixels i could just stack as many as i wanted on top of each other and the final image size would be a power of 2, what a twit. happily it seemed to work out in this case although each image works out at 204.8 poixels tall!

So in summary, Griff 1 OpenGl Programming Specification 0

If you want to make an animation of a different length, just modify the FrameCount value when you write out the ship data.plist entry for your new roof billboard object, here's the code for the drinking spaceman one, you just need to change the texture files to your new ones, the first texture listed (griff_no_shader_drinking_spaceman.png) is the static image version of your animation for use by players not using shaders, the second texture listed (griff_drinking_spaceman.png) is your animated texture (frames stacked vertically as usual).

Code: Select all

"griff_station_roof_billboard" = 
	{
	ai_type = "nullAI.plist";
	model = "griff_station_roof_billboard.dat"; 
	roles = "griff_station_subent";
	shaders = 
    { 
        "griff_no_shader_drinking_spaceman.png" = 
        { 
            vertex_shader = "griff_station_animated.vertex"; 
            fragment_shader = "griff_station_animated_billboard.fragment"; 
            
            textures = ("griff_drinking_spaceman.png"); 
            uniforms = 
            { 
				FrameCount = { type = "float"; value = 5.0; };
				TimePerFrame = { type = "float"; value = 1.0; };				
                uTime = "timeElapsedSinceSpawn"; 
            }; 
        }; 
	};	
	};

As I mentioned before, sort of, in my obtuse way, any frame count will work, but for non-power-of-two frame counts the height of each frame will be a non-integer which will result in misalignment effects if you have sharp vertical edges. (A one-pixel gaussian blur, where by “one pixel” I mean one pixel at the final texture resolution, will make this barely noticeable. Of course, the cost is that you get a blurry texture.)

Also note that if you stack five 256 px high frames into a texture, Oolite will scale it to 1024 px (5 × 204.8 px) when the texture is loaded and you might not notice. I made this mistake myself once (gasp!).

Ark, i've reworked the original shaders to add in some of the stuff from the griff_boa shaders (the bits to recolour the texture map)

I've uploaded it here http://www.box.net/shared/3inge0prh6

a while back someone posted a colourwheel picture, i've edited it a bit to add in floating point values for all the colours - the shaders i've used for the station need floating point values for R G B rather than the 0-255 scale the paint programs use, i don't know the way to convert between the 2 using a calculator but luckily rendermonkey can show floating point values for the current colour its colour picker window!
The station in the screen shot above has the top part of the station recoloured using the blue at the '7 o'clock position' on the colour wheel and the bottom bit is recoloured using the darker blue at the '8 o'clock position'

the changes from the original version uploaded ages ago are:

Code: Select all

Config Folder:
The following changes have been made to the original shipdata.plist

Line 205: smooth = "false"; key added, change to smooth = "true"; if you prefer
Line 240 now reads:  fragment_shader = "griff_station_bottom_section.fragment"; 
Line 241 now reads:  textures = ("griff_station_bottom.png", "griff_station_paint_mask.png");
Lines 242-248. New Uniforms to pass information to the new shader added.
    Line 246 MainhullColour - Floating Point R G B colour values to re-colour original texture map
    Line 247 DecalColour - Floating Point R G B colour values to re-colour the 'stripe' 
             painted roughly halfway down the cylindrical top section of the station


Line 257: smooth = "false"; key added, change to smooth = "true"; if you prefer
Line 263 now reads:                  fragment_shader = "griff_station_top_section.fragment";  
Line 241 now reads:  textures = ("griff_station_top.png", "griff_station_paint_mask.png");
Lines 265-271. New Uniforms to pass information to the new shader added.
    Line 269 MainhullColour - Floating Point R G B colour values to re-colour original texture map
    Line 270 DecalColour - Floating Point R G B colour values to re-colour the 'stripe' 
             painted along the top of the 'arms' sticking out of the bottom part of the station.

Line 358: smooth = "true"; key added, change to smooth = "false"; if you prefer

Models Folder
-No Changes-

Shaders Folder

griff_station_adring.fragment - Updated with new code
griff_station_adring.vertex  - Updated with new code
griff_station_animated_billboard.fragment - Updated with new code
griff_station_animated_w_rollbars.fragment - Updated with new code
griff_station_animated_w_rollbars.vertex - Updated with new code
griff_station_bottom_section.fragment - New Shader
griff_station_hull.fragment - Updated with new code
griff_station_top_section.fragment - New Shader

Textures Folder:
griff_station_paint_mask.png - New texture map, used by the relevant shaders to limit the recolouring of the station hull to certain areas of the model

griff_station_top.png & griff_station_bottom.png - original textures modified slightly to work with the new shaders (lights are now painted into the RGB channel and 'illuminated using the Alpha channel rather than being in a seperate texture map)

That looks fantastic!
Minor suggestion, to make the top colour always be one of the three colours opposite the bottom one on the wheel, as in the rule of complementary colours.
Not important it would just avoid strange clashes.
By the way I really liked your cobra, good stuff as ever.
Ooh I nearly forgot, I wanted to ask you can I re-name your Boa and Kraits ingame? I was going to call them Griffin for the Boa, and Harpee for the Kraits? Would feel wrong doing it without your permission

Griff · Post by **Griff** » Sat Jan 10, 2009 2:06 pm

@zygoUgo
I don't mind at all if you want to rename the ships, those sound like really great names!

I've added a sort of crappy LED pixel effect to the scrolling ad-ring shader, i've bunged it all into an oxp here http://www.box.net/shared/l07ll8kmxq (just the updated shaders & texturemaps and a small script to spawn them outside the station when you launch)
there's 2 versions, with differing 'LED pixel sizes' - it looks quite neat the way the texture scrolls through the grip of pixels - the bigger one looks nicer but you loose a lot of the fine detail in your advert texture map as it falls in the gaps between the led pixels (as you can see in the pic, most of the text has become unreadable)
anyway, since they exist i thought i'd upload them but i'm not suggesting you have to include them in the oxp or anything

Big LED pixels:

Small LED Pixels

edit: Forgot to mention, i generated the grid texture that is being used as a mask for these shaders using the free 'halftone' plugin by Richard Rosenman
http://www.richardrosenman.com/software/downloads/
very cool stuff, the 'scanlines' one is really good too.
There seems to be a guide on installing photoshop plugins in Gimp here:
http://akvis.com/en/graphic-tips/gimp-add-plugins.php
and here for linux http://www.gimp.org/~tml/gimp/win32/pspi.html
I haven't tried this myself though (i'm a posh photoshop user)

no, i've done something wrong, i'll get that fixed - it loks like a error in the griff_station_bottom_section.fragment code, probably a missing ; or something

Griff · Post by **Griff** » Sat Jan 10, 2009 3:05 pm

Hmm, i can't see what i've done wrong, there was a line in the shader that shouldn't have been there, the #define Blink_on_off(1.0) one.
what if you replace all the text inside the griff_station_bottom_section.fragment with this, does it work then?

Griff what version of oolite are you using ? A trunk version?

yes, i am using an old trunk version with the tangent space normal mapping code in it, but i don't think this error is related - i know this may sound like the ravings of a madman but i think it's my graphics card drivers, they leap in and fix errors in my shaders that other peoples graphics cards complain about and i always end up posting shaders full of bugs that run ok on my pc!

in this bit of the shader

Code: Select all

   #define LIGHT(idx) \
        { \
           vec3 lightVector   = normalize(gl_LightSource[idx].position.xyz); \
           vec3 reflection   = normalize(-reflect(lightVector, v_normal)); \
           diffuse += gl_FrontMaterial.diffuse * gl_LightSource[idx].diffuse * max(dot(v_normal, lightVector), 0.0); \
           specular += gl_LightSource[idx].diffuse * pow(max(dot(reflection, eyeVector), 0.0), specExponent); \
        }

are there any blank lines? there musn't be any blank lines or characters (including spaces) after the \ at the end of every line

Nop!! no black lines
I am using a Gforce9600GT with 180.48 drivers
What Kind of card is this that fixes shader problems?
Fascinating!!

Edit:
It only works with full shaders!! I am wondering why?

yeak i know, it's totally weird! I don't think Ahruman believed me either when i tried to convince him i had a magic graphics card installed in my pc. I've got an nvidia 8800gts card and i think the same graphics drive, that's the latest November 19th one isn't it?
anyway, i've uploaded the oxp again
http://www.box.net/shared/3inge0prh6
maybe something went wrong with the old upload when i edited it to fix the glowing paint stripes?
i've looked in the oolite log and i can't see any errors reported in there about this oxp, so hopefully it will work ok *fingers crossed*

Yes we have the same drivers.
Even more Fascinating!!

When i have shader effects in full it works ok. That is odd
