Component Prototype
Description
Video3D Component
This component is used to show a filed video stream on a rectangular flat area that can be positioned anywhere in 3D space.
In-slots
Name
Type
Description
visible***
boolean
The component is shown when true and hidden when false.
transformation***
matrix
This transformation matrix is applied to the component geometry when shown
Out-slots
Name
Type
Description
visible***
boolean
The in-slot is propagated to the out-slot
transformation***
matrix
This transformation matrix corresponds to the output transformation, which combines input transformation with the offset.

Description
iconFileName*
string
The filename of the icon shown for the component in the authoring environment.
offset***
matrix
The offset transformation matrix between the transformation given by the in-slot and the geometry model
videoFileName
string
File name of the video to be shown, where the stream is stored. It must be a .avi file
relativeSize
float
This parameter represents the proportionality factor of video size (referred to the height) respect to the original video.
aspectRatio
float
This parameter represents the proportionality factor of the video ratio (height / width) respect to the original video. A 320x240 video has an aspect ratio of 0.75; so it can be stored in 128x128 (or 256x128) and the aspect ratio set to 0.75 to have it undistorted.
step
double
The step is the number of video photograms between two consecutive framework frames.
fixPosition
boolean
When true, the video is shown in the position (xPosition, yPosition, 1000)
xPosition
float
Used only when fixPosition is true. It corresponds to the x offset where the video is shown
yPosition
float
Used only when fixPosition is true. It corresponds to the y offset where the video is shown
