Use ffmpeg to screencast in ubuntu. Here is a command to capture lossless mkv:
ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 30 -s 1024x768 -i :0.0+4,400 -acodec pcm_s16le -vcodec libx264 -vpre lossless_ultrafast -threads 0 output.mkv

Final with weapons and engines. And some thoughts on creating 2d/3d assets.

2010-09-15T12:17:00.001-07:00

Its amazing how easy it is to create 2d assets opposing to the 3d stuff. The steps from the "concept" to the thing you see on screen in 2d are really trivial compared to the 3d. Here's how i do it.

1. Do a nice sketch with a pen on paper

2. Cleanup the sketch a bit by copy it on the window :)

3. Shoot it with a webcam/camera

4. Trace it by hand in inkscape

5. Cleanup the traced splines and actually generate the final vector graphic.

6. Export to raster

7. Do diffuse

8. Do cel shading

9. Do Decals like text marks etc.

Here are some funny "concepts" :):

The final result:

Entirely done with a pen, paper and a mouse. Kudos to the people behind the amazing Inkscape program.

Some inkscape/gimp experience

2009-02-08T06:17:00.000-08:00

I have drawn this image using a pencil. Then I took a picture using a cheap webcam. I have imported the shot in Inkscape and traced it with splines:

Then I have stored the vector image as .svg file and reopened it in Gimp:

WHAT WE WANTED IT TO BE:
The game is a tactical shooter in a 2.5d isometric view. The game objectives vary on different maps and could be some of the well known from the rts and fps genres "capture the flag", "free for all", "destroy all enemy structures" or some custom modes like "take control of point X and remain in control for N minutes". A game continues about 20 minutes.

The maps are made of tiles and "brushes". Each tile is about 2 meters wide. A brush takes exactly one tile. There are only walls and passages but no bridges on top of the terrain and no high grounds a-la starcraft. The largest map is 256x256 tiles. The camera is with a fixed height and angle (less confusion for the players). All lighting and shadows in the game are dynamic.

Every player has 1 PC and up to 2 NPCs under his control. NPC can only take simple orders like "guard me", "guard X", "build structure X", etc. There are many "ambient" NPCs runing on the map, occasionally engaging in fights not controlled by the players. The structures placed on the map by the players are "turrets", "radars" etc. The PC (atleast for one of the fractions) is a cyborg. His body parts (legs, torso, left arm, right arm, head) are replaced during the game with visually different ones. The player starts with a completely "humanoid" body and gradually mutates into a machine with visually distinctive silhouette information about the PC stats are easily visible.

WHERE WE ARE:
Implemented are the structure of the world, the lighting, cel shaded animated models, static decors, a primitive editor, UI system, particle systems, a primitive art pipeline of exporters from blender to the game, a bit of network code and NO GAMEPLAY :). The demo runs on 32/64bit windows and linux. There is some minimal art assets done by me.

Im no longer working on this project. I just dont have the time anymore. Thanks to everyone involved! Im still checking this blog and I'll continue to post here. Any questions posted here will be answered.

The source code and the art is free for download atleast until assembla.com cuts me off of their service :).

Roboarm update

2008-07-21T01:17:00.000-07:00

I have decided to paint the AO this time, instead of bake it in blender. And im pleased with the result:

I paint the steel and modulate it with the "AO":

Some color:

Martyr video

2008-07-12T11:15:00.000-07:00

I have added some hack for demo recording. Here is a video of a demo.

Windows Binary (04.07.2008)

2008-07-04T06:50:00.000-07:00

Latest windows binary here

Tile decals

2008-07-02T13:39:00.001-07:00

I have added support for decal texture over the tiles. bumped up the FOV a bit:

Windows binary available

2008-06-24T03:13:00.000-07:00

I have uploaded the latest windows binary here

Screenshots, volume lights and more.

2008-06-21T15:29:00.000-07:00

the resources and code for the volume light fx are under version control now. added support for fx on each brush declaration. added support for screenshots inside the game. fixed a bunch of crashes in the console code. refactored the code for sprites/brushes/tiles. windows users have to wait until next week for a working source tree and binary. heres the disco screen for the day taken inside martyr for the first time

Volumetric light effect

2008-06-18T14:01:00.000-07:00

art:
- Im trying to implement volumetric light effects. Heres the result so far:

there is some problem in gnome when capturing opengl screenshots. the artifact on the leg of the character is gnome/glx fault. im going to implement screen capture support inside martyr anyway.

New tiles

2008-06-16T14:58:00.000-07:00

art:
- im trying a new method for creating tiles inspired by this game: http://www.rocksolidarcade.com/games/robokill/
here's how im doing it:
in blender: im making a contour, extrude/bevel it, render with an ortho camera and sun for a light
in gimp: fix the colors, make some detail/dirt, add some hilight and thats it. all made with the mouse. still look a bit sterile but it could pass for stylishness

2008-06-15T14:00:00.000-07:00

code:
- added support for self illumination on brushes
- the lights color can be scripted outside the renderer
- game split into client and server parts
- network code started

2008-05-11T13:21:00.000-07:00

Just created this explosion. The game engine supports sprites/billboards now. r_temp switches between blending modes for sprites.

2008-04-19T11:56:00.000-07:00

The code is officially GPL.
Fixed the crashes and artifacts in the lighting code on adding a brush on the map.
The contours and occluded silhouettes really work.
Any feedback is welcome.
Some keys and console vars/commands:

L - lights tab
B - brushes tab
T - tiles tab
arrow keys scroll the screen
'~' - console

printVars
printCommands
w_temp - how many characters to draw at the cursor
r_screenWidth
r_screrenHeight
r_fullscreen

2008-04-13T13:48:00.001-07:00

Ported to linux again. It was relatively painless this time around.

2008-04-12T05:41:00.000-07:00

Added support for silhouettes for occluded meshes. The brown guy runs. Blender exporters fixed.

2008-03-18T14:24:00.000-07:00

stress test made of 100 skinned, shaded, shadow casting guys with 1200 verts each, each lit by 7 shadow lights

2008-03-17T04:34:00.001-07:00

The brown guy exported ingame. Get the binary to mess around with it:

Okay this is the first update in a lot of time. Since there is some interest still in this blog I think its worth updating it. Ill start to upload images again as often as i can. I have put some here: http://www.gamedev-bg.net/phpBB3/viewtopic.php?f=13&t=1716

I'll fix the dead crimson force link.

Here are some images from martyr at picasa:

martyr progress:

Ported to SDL. No more ALT-TAB and windowed/fullscreen switch problems. No more restart for resolution change. Both under linux and windows.

2006-09-02T12:28:00.000-07:00

this isnt a progress update. today ive decided to have fun and run martyr on my old PII celeron 400mhz, 3dfx Voodoo3 machine. the shadows are turned off because the app segfaults when stencil buffer is set. env mapping, toon shader, contours and multiple passes on each lights are on. here is a screenie from my fluxbox desktop.

2006-08-27T12:59:00.000-07:00

martyr progress:

added environment mapping support.

2006-08-26T17:15:00.000-07:00

added shadows using shadow volumes and the stencil buffer.

2006-07-20T13:19:00.000-07:00

martyr progress:

optimized renderer
added light for cel shaded entities

2006-07-09T15:34:00.000-07:00

martyr progress:

old robot scrapped
new robot finished
light first attemts

some explanations on the contours: the contour of the pc/npc entities in the game is a mesh which is "fatten" and rendered with flipped normals and flat black color

some notes on the lights: the lights are applied as vertex colors. there is a separate pass for each shadow emitting light. there is a pass 0 which fills the z buffer and base light. tiles and brushes assigned to them with intensity 0 at each tile vert are culled out.

2006-03-19T11:37:00.000-08:00

martyr art progress:

robot revised. thanks goes to calader.

today i just draw this tile:
im starting to get the hang of tile painting. adding ovals of dirt inside the edge figures seems to do the job. i also played around with a screenshot in GIMP and i found that the game needs to be darker and more saturated. the shot was supposed to give me an idea about how the game will look with lights. the minimap is still broken. here are the original and the modded shot:
