void eq::server::Segment::setChannel ( Channel * channel ) [inline]

Set the channel of this segment.

The channel defines the output area for this segment, typically a rendering area covering a graphics card output.

Parameters:

channel

the channel.

Canvas* eq::server::Segment::getCanvas ( ) [inline]

Return the parent canvas of this segment.

Definition at line 79 of file server/segment.h.

void eq::server::Segment::setViewport ( const eq::Viewport & vp )

Set the segment's viewport wrt its canvas.

The viewport defines which 2D area of the canvas is covered by this segment. Destination channels are created on the intersection of segment viewports and the views of the layout used by the canvas.

Parameters:

vp

the fractional viewport.
