So, I’ve gotten most of the sprite functionality back into Gorgon 2.0. And of course, with the help of my stupid ball demo program I learned something neat… (click the “read the rest of this post…”, you know you want to)
Tag Archives: Gorgon – My 2D graphics library
So, here’s some more proof that I’ve been working on the next version of Gorgon:

As per the description on the youtubes:
An example showing the new version of Gorgon.
Currently this is just a simple sprite test using 1024 multi-textured sprites via shaders on Direct3D 11 hardware. It also shows a new feature that’s being planned (but not promising anything) to use the 3D stuff to allow perspective corrected sprites.
This video also shows depth for the sprites by walking a camera into the sprite cloud.
Currently getting about 1200 FPS with this (the selective multi-texturing really slows shit down).
Social networking.
I’ve decided to remove the social networking stuff. It’s only a fad anyway.
Seriously, Gorgon’s not big enough to warrant that stuff. It was a nice idea, but in the end futile.
Multi-monitor pain.
So, one of the shortcomings of the original Gorgon was that there was no support for multi-monitor. And I see now why I didn’t bother… what a pain in the ass.
Anyway, I finally figured it out. See, there are two ways to do multi-mon support in Direct 3D 9:

MSAA (Gorgon v2.x – Dorian)
So, to prove that I actually do work on stuff, I’ve uploaded a new video to the youtubes. This one shows off the ability to use MSAA in the new version of Gorgon.

To get this effect, in v1.x of Gorgon, you’d draw a series of fading sprites (Alpha of 0 from the start position to an Alpha of 255 for the current position). However, in this example I’ve used MSAA to simulate motion blur on a sprite. Nifty eh? On top of the nifty effect we also get full screen anti-aliasing, which is something the previous incarnation of Gorgon didn’t have.
Before you ask: no, motion blur will not be included as a function of the library, that’ll be up to the developer to implement.
The future.
I recently played around with my own library (see an earlier post about the sun effect) and I found it… well, lacking. In my day job I do a lot of framework/library code for re-use amongst my co-workers and I’ve learned a great deal over the last few years of doing that professionally. There’s a huge difference between writing a database/application framework and a graphics library, but, I’ve always been amazed how concepts from one architecture will map to another and as I developed Gorgon in my own time, I ported concepts to the framework code I write for my job and vice versa. One major difference is that our framework code at the office is always evolving from project to project (granted, the pace of evolution has slowed somewhat), while Gorgon was written, and aside from bug-fixes, it never evolved because I never really used it except to prototype small things from time to time. Until I wrote the Sun thingy….
Issue… where’s my tissue?
I became aware of an issue with the FromStream method on the Image object a few days after I posted the new installer. It’s been corrected and put in the SVN repository.
Please note that it is not included in the 1.1.4119.34319 installer, and won’t be until I release a new version. Sorry about that, but I’m a busy boy these days.
New version of Gorgon – 1.1.4119.34319
Yep, finally. I’ve rolled up all the updates/fixes that were in the subversion repository and put up a new version of Gorgon. Version 1.1.4119.34319 is the latest version and you can get it from here. You can view the change log in this forum post.
Enjoy.
Sun
So, I bet you’ve been wondering what I’ve been up to lately… You haven’t? You selfish bastard.
Anyhow, I’ve gotten around to playing with this library I wrote for a bit. I do so little programming on my own time these days and honestly, I never much cared for Gorgon (I felt it could have been better), that I haven’t bothered to try and write anything with it. That my users actually say it’s useful and well written comes as a complete shock to me. Anyway, this last week I mustered up some spare time and I created this abomination:
https://www.youtube.com/watch?v=PqPGa6P52LM
It’s not much, but it’s just a little thing I threw together to see if I could get a “bloom” type effect with a star. I did. And there it is. Note how the surface of the star moves around and all that. Neat hey? No? Shut up.
I’ve limited it to 60 FPS on purpose, but it is fairly swift. I think at one point I was getting > 1000 FPS. However, my vidja card is quite beefy, so take that with a grain of salt. So… yeah…. that’s all I have to say.
Enjoy.
Kids… take my advice… don’t grow up
I’m sure people think Gorgon is dead. Well, it’s not dead, but certainly not active either. I’m pretty much done with writing for it (bugs being an exception). If you’re interested in helping maintain it, please let me know via the forums. My day job and my social life (which I’d neglected for too long) are a priority right now and I have very little motivation (or time) to write anything related to Gorgon (or anything else).
That said, I do check the forums every day (at least twice a day). So if you have a bug, or need a question answered, I will try to help. Again, because of my “schedule” I may be a bit late in the replies (although ShadowDust702 has been doing a fine job of answering questions while I’m out drinki… er.. working).
Speaking of forums, forum member Cycor posted some code to convert GIF animations into Gorgon sprite animations. You can view the code here (sorry for the late acknowledgment).
Moar User Stuff
Well we have another user contribution from forum member domq. He’s doing a “sort-of” Ultima 6 MMO remake called Britannia On-Line. Frankly it looks awesome, and I can’t believe Gorgon can be used for stuff like that. Who knew? I sure didn’t.
Anyway, I’ve added screenshots of the project to the screenshots gallery under the user contribution gallery. You can check out more about the project in the forums.
Domq also found an issue with the TextSprite when the bounding rectangle is very small and WordWrap = true. This has been corrected (by domq) and I’ve put the fixed code into the Subversion repository.
User stuff
So I’ve been meaning to do this for a while, but laziness and real life gets in the way. Anyway, one of the forum members, Zeraan, has created a nifty little asteroids clone called Asteroids of Beyaan. You can check out the project (which includes a link to the game itself) in the forums. I’ve also added screenshots for the game in the screenshots section of the site under the user contributed screenshots section.
I’ve also added two new (well, not so new seeing as they’ve been there for a long time) screenshots for the RPC project by ShadowDust702. Those too can be found in the screenshots/user contributed section. Check the project description for a download (demo/test version) link.
New version: Gorgon v1.1.3638.20767
So I’ve finally gotten off of my lazy ass and uploaded a new version of Gorgon. This version contains all the bugfixes, and enhancements that have appeared in the Subversion repository over the last few months.
You can read about the changes here.
Then you’ll probably want to download it.
A tutorial? Now I is professional.
So ShadowDust702 was kind enough to create a basic getting started tutorial and put it on the wiki. This makes it look like Gorgon actually has some interest. Who knew? Anyway, the tutorial is here. If you would like to contribute to the cause, then by all means do so and let me know on the forums so I can tie it all together.
New version tiem! Gorgon v1.1.3436.39405
Yes, I know I spelled “time” wrong. Yes, it’s on purpose.
I’ve uploaded a new version of Gorgon today. That puts the current release at version 1.1.3436.39405. You can read what’s changed by heading on over to the forum and reading this announcment. After you’ve become completely brainwashed by reading that you can download it.
Clearly I’m still working on Gorgon. I probably will be until the day I expire, which given my healthy intake of McDonald’s, should be any day now. If someone wants to lend a hand, contact me via the forums.
Edit – May 29/2009
Because I’m very dumb, I released Gorgon with a nasty bug in the Batch sprite object. When you use the batch sprite it will complain that it can’t find the vertex declaration for PositionNormalDiffuseTexture1 or some such nonsense. This of course just totally breaks the Batch sprite. It’s been fixed and the new version (v1.1.3436.39405) is uploaded.
Sorry about that folks, sometimes Tape_Worm is stupid like ox.
