receive_display
receive_display -h
receive_display [-s] [-p portnum]
receive_display [-r resource] [-fwidth,height]
Description
receive_display is the output display program for the RIVA renderer.
It uses either socket or router connection to receive images from the renderer.
If receive_display runs without any arguments, it defaults to a
socket connection, port 7000, with border. receive_display quits
upon the keystroke 'q'. The connection specified by receive_display
must agree with that of hfb_host.
Options
-
-s
-
Use socket connection (default). Image size will be sent by the renderer
if using socket.
-
-p portnum
-
Specifies a socket port number. If not specified, port number 7000 is used.
Must agree with the port number used when running hfb_host (defined
using switch -t).
-
-r resource
-
Use router connection. Resource name must be specified with resource.
The resource name must agree with the resource name of the output destination
defined in flitrc.
-
-f width, height
-
When using router connection, buffer size must be specified with this parameter.
Must agree with what's defined in flitrc.
-
-h
-
Display usage message.
Usage
For receive_display with a socket connection,
% receive_display -s
connected to port 7000
Go for it
Be sure to wait for the "Go for it" message. The window for receive_display
will appear when hfb_host is started. Size for the receive_display
window will be determined by the renderer. If using a socket connection,
receive_display
must be started before hfb_host. The corresponding command to run
hfb_host
would look something like
hfb_host -c flit -p 8 -i earth.set -D socketlow -n RENDERER -o output/earth
For receive_display with a router connection,
% receive_display -r RenderTest -f 640,512
Using Router to communicate with RIVA.
Resource Name: RenderTest
Function Name: render_image
Image size: 640,512
Ready to read from hfb_host...
The window for receive_display will appear immediately, with the
specified size. The resource name for receive_display is the one
specified in flitrc. For the router connection, receive_display
can
be started at any time, and can be killed and restarted while the renderer
is running. The corresponding command for hfb_host would look something
like:
hfb_host -c flit -p 8 -i earthnew.set -D routerlow -n RENDERER -o output/earth
