Hi all! I think my first OXP is finally ready for release. I hope you enjoy it!

In high orbit on the dark side of Tionisla, the famed Tionsila Chronicle broadcasts the latest news across the galaxy.

Sixty hexagonal high-intensity FTL transmitter panels - each one fully half a kilometer across on opposite points - adorn a trio of arms each nearly two kilometers long that protrude from the central hub of the broadcast array. The incredible amount of energy fed to the panels means that the TCA is visible from the planets surface, despite it being constantly shrouded from the sun.

The Tionisla Chronicle Array is home to a huge staff of maintenance engineers, holocam crews and of course reporters, delivering to you up-to-the-minute breaking news no matter where you travel.

The Tionisla Chronicle Array is by no means the only Broadcast Array across the eight charts, although it is the most famous.

The Tionisla Chronicle Array - Tionisla, Chart 1
The Views of the Worlds Array - Xeabiti, Chart 2
The GNN Array - Geusdi, Chart 3
The Daily Wail Array - Quonzo, Chart 4
The G5TVN Array - Maeser, Chart 5
The Rooters Array - Tiregees, Chart 6
The StarSports Array - Zarausxe, Chart 7
The Snoopers Array - Maabile, Chart 8

The TCA oxp can be downloaded at: http://www.box.com/s/jcbh1c7qryhn0pui2ndg

I hope to add missions and appropriate station traffic in future versions.

My thanks to Drew, DaddyHoggy, Svengali, and Disembodied for use of the Snoopers OXP channels.
Credits to Smivs for the G5TVN Channel.
Thanks to DaddyHoggy again for Views of the World and the Daily Wail channels.
StarSports is my own channel addition.
Thanks to Okti and Cim for scripting help.

Looking magnificent storm, will try it now.

A marvelous ambience oxp, Storm!

Downloading.

I think with the TOG and now the new station in it the Tionisla system in my personal ooniverse is rather densely populated. I hope this will not result in a price explosion on the property market in the Tionisla system. Even more I hope this will not result in a framerate drop in the imac system.

Best regards

C.B.

V1.0.1... hopefully fixed the lighting issues for older OpenGL machines that were getting rather dull looking broadcast arrays. For non-shaders, I still am having issues getting the billboard display screen inside the dock to change emission maps via javascript to the correct galactic chart channel. Hopefully this won't foxoid me for long (or someone else points out a glaring error that I've missed so far!)

... and thanks to Thargoid for pointing out that glaring error for me.

v 1.01 still gives errors, but less of them:

Code: Select all

Also, it has only a small 'b' instead of the nice beacon symbol.

In case of broadcast_array_display.fragment I see one possible source of the problem at the end of the three lines

Code: Select all

	float ScrollingDisplayR = texture2D(uEffectsMap, vec2(vTexCoord.s + counter - flipCounter - flipCounter2, vTexCoord.t + (0.125 * uGalaxy))).r;
	float ScrollingDisplayG = texture2D(uEffectsMap, vec2(vTexCoord.s + counter - flipCounter - flipCounter2, vTexCoord.t + (0.125 * uGalaxy))).g;
	float ScrollingDisplayB = texture2D(uEffectsMap, vec2(vTexCoord.s + counter - flipCounter - flipCounter2, vTexCoord.t + (0.125 * uGalaxy))).b;

because of

Code: Select all

uniform int		uGalaxy;

I don't see something similar in broadcast_array_dock.fragment, though.

If I'm right, how can it be fixed?

Stunning work, Storm. Huge appreciation from me. Great to see the Chronicle 'come alive'

Bravo.

Cheers,

Drew.

Fantastic work! Fiction becomes Ooreality!

. I like it!

Wow, that is a lovely piece of work!

Well done.

I just downloaded version 1.02 and still get above error. The reason is that uGalaxy is bounded to the float 'fuel' but defined as a int in the shader. Changing above line into:

Code: Select all

uniform float		uGalaxy;

fixes all errors with me. That just leaves one discrepancy: in the JS script, the fuel is set to galaxyNumber/10, but in the shader it looks like you try to convert it to a galaxyNumber by multiplying with 0.125. Should that not be multiply by 10?

Anyhow, the array looks amazing now, compared with the 1.0 version were no shaders were visible on my system. And because the station is placed outside of direct sunlight, it needs shaders to get some light, as it has now with working shaders.

The Fuel shader uniform is in one-tenths (0-70) so assigning each station the galaxyNumber/10 of fuel in javascrtipt meant a value of 0-7 when passing to uGalaxy. The *0.125 is the offset of the texture's total height as a percentage on the Y-coordinate - so for example galaxy 3 would offset the texture by 37.5% of the .png's height. Of course I could have left out the /10 and just have multiplied by 0.0125 instead inside the shader.

Anyway thanks to cim I've got the issue with the scrolling billboards fixed for the older OpenGL issues and v1.03 is now uploaded.

This is most cool. In this version the shaders on the hexagons and the ticker are looking on my (not-so-old, less than one year old actually) Thinkpad E520 with Intel HD Graphics 3000 & Xubuntu as they should.

Before (up to v.1.02):

After (v.1.03):

This OXP is very "polished", great job.

Nice work, looks sharp. The first thing I did was check out The Views of the Worlds Array (Xeabiti, Chart 2), which was just one jump away from my homeworld of Esceso.

I think that someone needs to do an updated Tionisla video, featuring the pulsar and the array....

Posted: **Fri Mar 23, 2012 7:15 pm**

The pulsar's Tianve, nor Tionisla.

Whoops!
