TriDef Ignition
In-Game Control
Ignition OSD
3-D Menu
The 3-D sub-menu controls rendering of the stereoscopic 3-D
effect. 3-D rendering can be turned off to render the game
without stereoscopic effects, in a pass-through mode.
The scene depth and percent behind screen
control the strength and positioning of the 3-D effect,
respectively.
TriDef Ignition has a unique method for optimising the 3-D
effect, called Auto Focus. Auto Focus essentially
detects the location of objects in the scene and modifies
the 3-D configuration accordingly. The Auto Focus
calculation needs to be repeated frequently to detect any
changes in the scene.
The "Focus Speed" parameter enables you to control
how quickly the configuration changes. Increase the speed
if you always want to maximise the best 3-D result,
decrease the speed if you prefer more gradual changes.
The three fixed modes: fixed1, fixed2 and fixed3
essentially turn Auto Focus off. In this configuration the
3-D configuration is fixed and does not adapt to objects in
the scene. Select one of the fixed modes if the Auto Focus
is not working optimally (such as fluctuations or a poor
3-D range). The three different fixed modes make different
assumptions about the location of objects in the scene.
The Custom focus mode is designed for advanced
users. In particular, care should be taken to ensure the
settings produce comfortable 3-D in different parts of the
game or application.
The "expand" mode falls is a compromise between Auto
Focus and fixed focus. The Expand mode cumulatively adjusts
the 3-D configuration over time as new objects are detected
in the scene.
TriDef Ignition optionally separates the scene into 3 main
zones: gun, scene, sky and it is possible to
configure auto focus parameters separately in each zone to
get the best possible 3-D effect.
When in Auto Focus mode, the Stability parameter
provides a more fine-grained control over the focus speed.
Between 0-9 the stability equates to "Instant", between
10-49 the stability value equates to "Fast"; values larger
than 50 are equivalent to "Medium". Stability values beyond
50 equate to the "expand" mode behaviour.
Additional constraints can be placed on the behaviour of
Auto Focus by controlling the minimum range and minimum
depth size. The minimum range determines the smallest 3-D
volume, regardless of the objects in the scene. The minimum
depth size enables objects to be excluded from the Auto
Focus calculation if they are too close to the observer.
When using multiple zones (gun, scene, sky) it is possible
to configure the contribution of each zone to the total 3-D
effect. For example, it is possible to set the gun zone to
occupy 20% and the sky zone to occupy 30% of the 3-D space
and therefore the scene occupies the remaining 50% of the
scene.
The Scale by Viewport option, when switched on, uses
the viewport's depth range to affect the 3-D configuration.
If the game or application has not set viewport depth range
to an appropriate range this can impact the 3-D quality.
When this option is turned off, the viewport's actual depth
range is ignored and a default value is chosen.
Performance Menu
Virtual 3-D is another innovative feature of TriDef
Ignition that is not available in other commercial
stereoscopic game drivers. By default TriDef Ignition is
configured to render the same scene twice, with a small
viewpoint shift (in the same way most other drivers
operate). This produces the best quality results but is
very resource intensive and quite inefficient.
The Virtual 3-D mode is faster method of approximating a
viewpoint shift based on the principles of image based
rendering. There is a trade-off in terms of 3-D image
quality, which may be noticable at the edges of objects but
it is likely that you will get a significant increase in
frame rate if you switch to Virtual 3-D mode.
The Quality parameter is also designed as a means of
trading image quality for speed. By reducing the quality
the frame rate can be increased.
The performance of TriDef Ignition is dependent on factors
such as the graphics card and graphics drivers. The "3-D
Texture Copy" allows the user to switch between
different methods of passing 3-D textures around the system
to assess the impact on performance. The "auto"
setting attempts to find the best setting for your system
automatically.

Performance Tips on our online forum.
Options Menu
3-D Object Detection: custom/mode 1/mode 2/mode 3
Select a combination of methods to detect whether a 3-D
object is drawn.
Custom is a method preset by DDD for that particular game
profile.
-
GUI Threshold Set a cut-off point in depth so that
everything placed in front of it is classified as 2-D
GUI.
-
GUI Offset Increase this to make 2-D GUI detected
by GUI Threshold poping out of the screen.
-
Matrix Names For advanced users to pick which
vertex shader matrices are used to draw 3-D objects. In
general, all matrices containing the word "projection" or
"proj" should be included, but the word "light" or
"shadow" should be excluded.
-
Row-Major Matrix Some games use row-major matrices
to draw 3-D objects. Switch this on if all the objects
look very wrongly transformed.
Gun Detection Detect the gun in some games. Only
effective when the gun focal zone is enabled in Custom Focus.
GUI Detection Available in Virtual 3-D Mode. The
driver tries to detect the graphical user interface (GUI)
and draw it in 2-D. Increase the aggressive level if the
GUI is not 2-D. Decrease it if some 3-D objects are wrongly
rendered in 2-D.
Go 2-D on fullscreen effect Render everything in 2-D
after a fullscreen effect is applied.
Go 2-D on square texture Textures in square sizes
are rendered in 2-D.
Track 3-D Objects on Main Surface Objects drawn on
the screen are tracked so that the focus can be adjusted.
Only effective when the scene focal zone is set to Auto or
Expand.
Track 3-D Objects on Any surface Objects drawn on
any surface are tracked so that the focus can be adjusted.
Only effective when the scene focal zone is set to Auto or
Expand.
Disable Incompatible Shaders Do not draw the objects
if one of the shaders is not 3-D incompatible. Only
effective when 3-D Texture Copy is enabled.
Detect SkyBox Detect the sky in some games. Only
effective when the sky focal zone is enabled in Custom
Focus.
Window and Cursor
The controls in this sub-menu enable you to control the
bahviour of the cursor and the size of the rendered 3-D
image.
Image Stretch Enables you to change stretch the 3-D
image horizontally to fill the screen. When the stretch is
set to 0 the 3-D image is rendered at the resolution
determined by the game. By default the 3-D image is
stretched to cover the entire width of the screen (stretch
value 100). If the aspect ratio of the game resolution
differs significantly from the aspect ratio of the display
objects may appear distorted and your preference may be to
reduce the image stretch.
Image Overscan On some projection display systems,
such as the 3-D Ready DLPs, the position of the image may
overlap with the screen area. This is referred to as
overscan and leads to cropping. TriDef Ignition provides a
means of controlling overscan by expanding/or shrinking the
image to avoid undesirable cropping.
Remap Cursor In order to accurate locate the cursor
position in 3-D it is necessary to remap the cursor
position. There are several different modes of remapping.
If the game is not responding to mouse actions then try
changing the remapping mode.
Clip cursor Cursor clipping stops the mouse moving
to an offscreen area, which can then lead to the
application switching context. If the mouse is overly
constrained within the game, such that certain controls
cannot be access then try disabling mouse clipping. freely.
Force Fullscreen resolution Ensure that the 3-D
image is displayed at the native resolution of the display
system. For example, if you have a 1920x1200 3-D display
and the game resolution is set to 800x600 then the 3-D
driver will scale the final image to 1920x1200. Also refer
to the section on performance in the online forum.
Force Fullscreen Window Position This option can be
used to assist the positioning of the 3-D window when using
multiple monitors. If the position and/or appearance of the
3-D window is incorrect try enabling this option.
Force Windowed Mode to Fullscreen Certain DirectX9
applications do not render fullscreen but render into a
window. Enable this option to scale the window to the
fullscreen. Note that this option only takes effect when
restarting. Also note that certain applications may crash
with this option enabled (for example Google Earth). In
this instance, revert to the original profile or the
generic profile.
Force Repaint Every Frame Repainting controls how
the game's display is refreshed. If the game appears to
flash too often try turning this option to "never".
Webcam
The Webcam options allows you to control the view of the
game by moving your head side to side. Note: this option
does not currently work in virtual 3D mode, only true 3D
mode, and requires an installed Webcam to work.
Select the Mode option to change the mode to Head
Tracking. The Status field will then change to reflect
the state of your Webcam - if it working, then the status
should change to Tracking, otherwise and error will be
shown.
You can turn on the Show Preview to see the capture from
the Webcam. You may need to move the camera to ensure that
your head is reasonably centred in the frame.
Once you have turned on the Webcam, it is a good idea to
calibrate the system to ensure accurate tracking. First,
use the Calibrate Background option to capture the centre
location. Ideally, this would be a capture without your
head in shot - however if this is too difficult, then a
capture with your head in the central position will do.
Next, lean to the left as far as is comfortable and use the
Calibrate Left option, and then lean to the right and use
the Calibrate Right option.
Now when you move your head, the Position item should
change to show -1 when you are leaning left and change to
+1 when you are leaning right.
If you significantly adjust your position during game play,
then you should recalibrate the system.
When using the Webcam, you should be able to lean to look
around corners, (although you will not be able to shoot
around corners). The Scale option allows you scale the
change in view position to suit the game. Some games use
aggressive object culling and some objects may disappear if
you change the view too much - this can also affect
auto-focus. In such situations, we recommend that you
reduce the Scale setting.
3-D Screenshots
3-D screenshots are stored in My Pictures. They are created
in three different formats: TriDefPhoto, side-by-side,
and anaglyph. TriDefPhotos can be viewed using the free
version of TriDef
Media Player. Screenshots are available on the forum pages.
