Game Engine Development: 2D Image Filtering, Speedup

Published by Bart on November 23rd, 2007 in Development

Iranian Blender developer Hamed Zaghaghi has been working on some rather cool new functionality for the Blender game engine. Not only did he add 2D image filtering capabilities (like motion blur), he also worked on a patch to speed up the OpenGL display of the game engine.

Hamed writes:

2D Filters are image filtering, that apply on final render of objects, I implemented some simple 2d filters for blender game engine. New implementation of 2D Filters has some features like enabling or disabling a filter on a specific pass, custom GLSL filters.

You can read all about his project on his website. I can only hope that his code will be integrated into the main trunk.

wow!
and what about his Volumetric Material?
2 Bart Nov 23rd, 2007 at 8:49 pm

There's not much more to tell about that other than the fact that he has a screenshot with a new button called 'Volumetric' ;-)

The title is 'Game Engine Branch…', is there actually a subversion branch that can be checked out?
4 Bart Nov 23rd, 2007 at 9:02 pm

@dreblen: no, I don't think there is.. I've updated the title.

Wonderful, any GE addition is always welcomed. Is this already in the SVN?

Hi Hamed congratulations! Don´t give up! :)

The site has been officially 'blendernationed'. Really wanting to download the examples. Guess I'll have to come back in a week or two! Still waiting to get back on to Antonio Gessi's fluida site to download the whole lot!

People should really learn how to make torrents. A whole lot of people can help increase the download speed. It's a no brainer.

WOW!

I cannot see any of the images at the site, but these are really great news! Adding those filters and the speedup of the engine is great for us GE lovers! It's been a while since the addition of the Bullet engine, and I was starting to miss news about the GE. (Anyone remember doogs's "bring back the game engine" song?)

Anyway, I hope that this calls the attention of the dev team so that they can add the chaneges to the official version.

I also hope that someone is brave enough as to spare some bandwith and upload the custom build, or at least become a torrent seeder!

Hamed, thank you for your excelent contribution!!!

thanks for the sweet work on the GE Hamid!! Apparantly right now he's working on a volumetric filter to help out project peach but after that he's going to improve the GE even more. Definitely good news.

"I can only hope that his code will be integrated into the main trunk."

There is so much awesome code running around still in development, and they ALL should be whumped into that Blender 2.5.

@dreblen: yes it's a subversion branch that you can checked it out here:https://svn.blender.org/svnroot/bf-blender/branches/game_engine/

sorry for my website, i didn't think that googlepages.com has bandwidh limit( :( ).
13 Oblenob Nov 25th, 2007 at 12:09 pm

I donthink that uploader.polorix.net has a bandwidth limit try there.
14 hamed zaghaghi Nov 25th, 2007 at 12:29 pm

@Oblenob: i registered a new domain and host, and will be available as soon as possible

Great work Hamed!

I look forward to seeing this make the next main release, especially the OS X version! ;)

torrent to the exe is up at http://www.mininova.org/tor/1011592

Why are we even developing the game engine anymore? It's feature bloat left over from the expansionistic NaN days, and is just slowing down Blender's progression overall. :/

@Kargath:
I personally would love to see Blender become a viable tool for creating games with no programming required. Being a programming autodidact is far more difficult than being a Blender and Blender GE autodidact.

Aside from that, it's nice to have rigid body physics as an animation tool. It would be best if that function were integrated, like the other physical simulators in Blender, but the current implementation is better than none, IMO.

Ok, since google is limiting teh bandwidth, i have a mirror for the exe here: http://mpan3.homeip.net/?blenderglsl
21 bmxican Dec 7th, 2007 at 4:27 am

is a glsl enabled graphics card required to show the filters?
22 hamed zaghaghi Dec 9th, 2007 at 11:34 pm

@bmxican: yes
23 bmxican Dec 12th, 2007 at 7:31 pm

aha! might be why they didn't work for me :)
