Custom User Content
There are several considerations to keep in mind when creating custom content to
control with the DL.2 graphics engine software.
Read the following specifications and recommendations before creating custom content. If a file
is not DL2 compatible, it may load but not appear as output. The CMA thumbnail view of content
will note incompatible files with an X.
Creating Video Media Files
Cleaner on Mac and Expert HD or TMPGEncoder on PC for encoding solutions offer good
quality and the most reliable DL.2 playback.
Any encoder you use will need to provide options that achieve the following specifications:
• Size to 640x480 pixels
• All I-frames (an I frame every 1 frame) for optimal tracking
• Constant Bit Rate (CBR) data rates of 10 to 12 megabits/sec
• Closed Group of Picture (GOP)
• Sequence headers each GOP (every frame)
• Progressive frames (since it's a progressive display device, not interlaced)
• End of sequence “Sequence Style”
All the encoders have demos and will batch encode (ExpertHD need a small script and a settings
file to batch encode).
* TMPGEncoder includes filters that let you light optimize in the encoder.
Creating 3-D Objects
In general, any 3-D modeling program can be used to create objects. If the particular 3-D
modeler does not export in DirectX .x format, a translation program will be needed to translate
the object from the modeler's output format to the DirectX .x format. For example, you can use
Newtek's Lightwave 3-D
®
modeler to generate 3-D objects in .lwo format, and then convert the
object to .x format using Deep Exploration from Right Hemisphere.
The following list includes some general notes and tips for creating a custom 3-D object.
• With the control parameters (position, scaling and rotation) set at their default values, a
rectangle measuring (13.0m, 9.65m, 0m) will just fill the screen.
• Objects are stored in Microsoft's DirectX .x format. .x files may be stored in either text
form or binary form.
