SPARK#43 – Killing the Horse

Dear Friends of Realtime 3D Graphics,

I guess, you all know the joke about how to ride a dead horse. Here’s one of the thousands of links that publish this old story, which has been happening in history all the time and again and again:

However, before we will have sold the dead horse to the new owner – who shall then perform the preparation of the dead horse for another owner – we must hide the fact that the horse is already dead (de facto).

Hence we shouldn’t talk too much about Web3D graphics and relativity, at the time being, because relativity will kill the current horse and replace it by the next horse, but the current horse is not yet sold and shall not be “eaten” by the next horse.

Hidden Hints about 3D Graphics and Relativity

However, I brought a few points about 3D graphics and relativity – as far as I can grasp and understand it – as easter eggs into my narration about “The third child”:

The narration can be found HERE.

The first and second part of the narration do not publish any idea about relativity, but a subtle hint: One of Walter’s children is named “Lieserl”, which was the first name of Albert Einstein’s first daughter (it’s a short form for “Elisabeth”).

More Clarity in Part Three of the Narration

In the third part of the narration, in a side story the siblings Lieserl and Conrad Peter work on a Software Project about relativistic software. It’s nowhere explicitly mentioned that it is about 3D Graphics, but the third part will not be actively pursued anyway, until “the horse will have been sold”.

Following chapters of the narration are relevant:

Lieserl is attending a lecture on general relativity.
The lecturer: “And at the end of this year’s lecture I would like to draw your attention, dear colleagues, to the fact that there will be a competition next year.
There are only a few years left until the 400th anniversary of the principle of relativity and so we would like to consciously set incentives to develop software programs and software concepts that are only based on the theory of relativity and no longer on the approximations of classical physics. So, ladies and gentlemen, if you have a good idea about the summer, get in touch with me. Prize money and recognition from the academic senate beckon. “[…]

Lieserl and Conrad Peter are sitting in an ice cream parlor, it’s a sunny summer day.
C.P .: “Thank you for inviting me”
Lieserl: “You don’t pass the technnical college diploma every day. Do you already know how to continue? Are you going to study too?”
C.P .: “No, I’m looking for a job now, my freedom is more important to me.”
Lieserl: “Say, Conrad, you know your way around computers.”
C.P .: “Well, let’s put it this way: everything that has a CPU usually obeys me.”
Lieserl: “Yes, that’s what I mean. We have a competition for relativistic approaches in computer technology at our university.”
C.P .: “I’m sorry, I don’t understand anything about the theory of relativity.”
Lieserl: “I can explain that to you. Differential geometry is about always describing small parts of the universe with equations and then putting the large universe together from small parts. <E Minori ad maiorem>“.
C.P .: “That reminds me of our good old ‘My Reality’ computer game. There we also put the scenes together from partial scenes”.
Lieserl: “But it is important that none of the parts have a special position
C.P. (pulls the air through between the teeth): “That will be difficult”
C.P. (thinks for a while): “But do you remember the railway line from Wiener Neustadt to Puchberg, which we had as children? It could represent part of the scene. If we now add the data for the main line from Wiener Neustadt to Mürzzuschlag then we could put the scene together from two parts and also program the handover “.
Lieserl: “Well, we’ll do that!”[…]

Conrad Peter started thinking about Lieserl’s project. Now they sit together and discuss the details.
C.P .: “Well, roughly speaking, our software will consist of three parts”
Lieserl: “Nice number” (giggles)
CP: “First of all there is the” telecommunications infrastructure “. This is the basis of the whole thing, so we should be flexible and support every possible type of transport layer: http, https, TCP, UDP, SCTP, TLS, RTP, SRTP, XMPP, SIP, 3GPP IMS, 3GPP MCx and whatever they are called.”
Lieserl: “Yes, I understand that. This is where we will have to communicate most of the time with other projects. Is it OK for you if I take on this part?”
CP: “Yes, of course! The second part is the protocol in the application layer, on the one hand to connect the scenes with one another via a broker, and on the other hand to connect special “blind scenes” to the real objects via brokers. I would do the part gladly take over. I already have some ideas for an <Event / State Description Protocol> ESDP “.
Lieserl: “Yes, that suits me very well. But you mentioned three parts, where is the third one?”
C.P .: “Exactly the third part is the problem. It’s about the download of geospatial data through a distributed database. So far I have no plan how we could approach it”.
Lieserl: “Well, but it’s a start.” (hesitates briefly, has a flash of inspiration) “but can you remember the dealer who got us the Semmering Railway? He surely knows a lot about downloads, uploads and the combination of geodata.”
C.P .: “Could be, but we don’t have his name”.
Lieserl: “No, not that. But maybe you can still find his phone number. You know, I know how to hack phones”.
C.P .: “OK”[…]

Lieserl and Conrad Peter have thought about their project and meet again in the ice cream parlor to forge further plans.
C.P .: “A few days ago I came across a good article about <Mixed Reality>”.
Lieserl: “Is that where you hide behind an avatar so you don’t have to come out?”
CP .: “No, that is <Virtual Reality>, but things have to do with each other. <Mixed Reality> is actually just the umbrella term for some very different technologies that are supposed to enable us to better cope with <real> reality come to <enlarge> them. “
Lieserl (looks uninterested): “Aha. And what does that have to do with our project?”
C.P .: “That has a lot to do with and with what you have achieved with our <dealer> of geodata” (says the word “dealer” in a disparaging tone)
Lieserl (ostentatiously rolls her eyes): “Oh, him! I’m not interested in him.”
C.P. looks a little confused, thinks: “Well, maybe the distributed database is not the most urgent of the three software components. So let’s start with the telecommunications infrastructure”
Lieserl: “Yes! Our project will require many services from the lower layers:
– Telephony (audio and video)
– telegraphy
– Position and status reports
– Geographic Infrastructure
So we will need a flexible hierarchy of networks in which all services are integrated – an <Integrated Services Digital Networks, Tree of> – ISDN / To, so to speak.[…]

Lieserl and Conrad Peter get together again to talk about their relativistic software project. You will see how multiuser scenes could “give the Virtual Globes a go” and why the Virtual Globes are dependent on a large number of users[…]

Lieserl and Conrad Peter are making progress with their project.
You find out what it has to do with the theory of relativity.
But unfortunately it is too late to compete.
Judgments are made[…]

After Thanksgiving – it’s raining and it’s “typically Irish autumnal” – Lieserl and her fellow student sit at the window for a long time and talk.
He asks her why she came to Ireland from Austria, but she gives an evasive answer. They talk – also – about astrophysics and the software project.
You have a realization: if the multiuser scenes and the virtual globes do not cooperate, nothing can come of the whole thing.[…]

Closing Remarks
