[Gate-users] [Gate-devel] [NEED TESTERS] View CT image with OpenGL within GATE

[David Sarrut]

Hello Jérôme,

this is a first feedback with all mailing lists in copy to let everybody
know, but we will then continue to discuss some technical points privately.

First, it works well and will be very useful to lot of users, thanks really
a lot ! As an example, here are a screenshots of a proton treatment plan
(with only 10 protons). With the QT interface, we can then easily rotate
all the scene and look what append. This feature will surely be included in
the next version as it will allow users to easily check the orientation of
their image in the scene.

Here are below a couple of technical details which should however be
addressed before, and we can work together on that :

- first it only works with G4 9.6 version ; not with 9.5. It also has some
trouble with version 10.0, but it is maybe not related to the
visualisation.

- I tested on Linux, work perfectly

- I only tried with the QT version ; a weak point is that it is not
possible to start the simulation from the command line. We need first to
start "Gate --qt" than type "/control/execute mymacro.mac" into the gui. It
should be more efficient if one only has to enter "Gate mymacro.mac" and
the gui+simulation start together.

- what does : "/gate/image/vis/forceWireframe" ? is it needed ?

- what does : "/vis/drawVolume" ?

thanks again Jérome,
David
