Doremi GENeration3D - Manual (Page 18)

4 Using Custom Patterns
The Generation 3D allows users to create their own custom test patterns. Simply create the ppm
files, name them accordingly, and place them in a folder on the SD card. The Generation 3D will
scan the SD card and determine whether the patterns are 3D or 2D and display them in the
Patterns menu.
Customer patterns can be used by manually adding them to the SD card or using the Doremi
Universal interface software. This section covers manually adding patterns to the SD card using a
PC , for instructions on creating ppm images and saving them to the SD card using the Doremi
Universal Interface software see Section 6.4.1.2.
4.1 Supported Image formats
• The Generation 3D supports only ppm images. Any other file type will not be recognized by
the Generation 3D.
• Image height and width should conform to one of the resolutions supported by the
Generation 3D. If the image size is different than one of the supported resolutions, it will be
padded to fit into the closest supported resolution (e.g., 800x600 will be padded to fit
1280x720).
• Supported resolutions are:
◦
1280x720
◦ 1920x1080
◦ 2048x1080
• Custom patterns must be 8 bit RGB at full range (0-255)
• Images larger than 2048x1080 are not supported.
4.2 File Naming
• 2D images must be named filename.ppm (e.g., pattern.ppm)
• 3D Images must have the same filename and be tagged with “_left” and “_right” to identify
which eye the image corresponds to (e.g., “pattern_left.ppm” for the left eye image &
“pattern_right.ppm” for the right eye image).
4.3 Manually Adding Files to the SD Card
1. Format the SD card as either FAT or FAT 32. NTFS is not supported.
2. Create a folder on the root directory of the SD card named “Patterns”. All the patterns will
be placed in this folder.
3. Create a folder inside the “Patterns” folder. The name of this folder will be the name
displayed on the front panel of the Generation 3D for the pattern contained within.
4. For 3D patterns, place the left and right eye ppm image files in the folder created in step
two.
• For 2D images, place the single ppm image file in the folder created in step two.
5. Insert the SD Card into the Generation 3D and your pattern will be available under the 2D
or 3D Patterns sub menu.
