CED is a server client application for OpenGL drawing
CED is distributed under the GPLv3 License
For building CED from source you need to have CMake and CMakeModules for ilcsoft installed in your system. ( cmake homepage: www.cmake.org ) once cmake is in your $PATH, follow this steps:
mkdir build
cd build
cmake -DCMAKE_MODULE_PATH=/path/to/ilcsoft_CMakeModules [-DCED_SERVER=ON] ..
make install
NOTE: Only the CED client library is built per default!!
If you also need the display server (glced), you have to explicitly set the cmake option CED_SERVER to ON and you need GLUT installed on your system ( http://freeglut.sourceforge.net )
If cmake cannot find GLUT you can use the variables
CMAKE_LIBRARY_PATH and CMAKE_INCLUDE_PATH to find libraries
and header files in non-standard paths, e.g.:
export CMAKE_LIBRARY_PATH=/path/to/glut/lib
export CMAKE_INCLUDE_PATH=/path/to/glut/include
cmake ..
make install
The users manual can be found at ./doc/manual.pdf
glced -h # show help
glced # run event display server
The window has to be active and the mouse placed inside it.
ESC .......... quit
CTRL+s ....... save screenshot
keys [0-9] ... toggle visibility layers
key 'r' ...... redispaly in some initial projection
key 'f' ...... front projection
key 's' ...... side projection
key 'c' ...... move center of rotation to the nearest hit within current mouse position
key 'v' ...... fish-eye view
key 'b' ...... toggle background color
key 'h' ...... display help menu
L button + drag: rotate
R button + drag: pop-up menu
M button + drag: shift
M wheel + up : zoom-in
M wheel + down: zoom-out
Somewhere at the beginning of file ******Processor.cc
#include <ced_cli.h>
// Visibility layers types: should be included as:
#define PHOTON_LAYER (0<<CED_LAYER_SHIFT)
#define PHOTON_LAYER (1<<CED_LAYER_SHIFT)
#define NHADR_LAYER (2<<CED_LAYER_SHIFT)
#define CHADR_LAYER (3<<CED_LAYER_SHIFT)
#define TPC_LAYER (4<<CED_LAYER_SHIFT)
#define ECAL_LAYER (5<<CED_LAYER_SHIFT)
#define HCAL_LAYER (6<<CED_LAYER_SHIFT)
...........................
#define SOME_LAYER (19<<CED_LAYER_SHIFT)
Once per task in first init:
void *********Processor::init() {
// Initialize event display
ced_client_init("localhost",7286);
ced_register_elements();
In the first called Processor::processEvent( LCEvent * evt )
initialize the geometry:
//-----------------------------------------------------------------------
ced_new_event(); // Reset drawing buffer and START drawing collection
// The Simplest geometry has Z axis as beam axis
static CED_GeoCylinder geoCylinders[] = { // for TESLA Detector Geometry
{ 50.0, 6, 0.0, 5658.5, -5658.5, 0xff }, // beam tube
{ 380.0, 24, 0.0, 2658.5, -2658.5, 0xff }, // inner TPC
{ 1840.0, 8, 22.5, 2700.0, -2700.0, 0x7f7f1f }, // inner ECAL
{ 2045.7, 8, 22.5, 2700.0, -2700.0, 0x7f7f1f }, // outer ECAL
{ 2045.7, 8, 22.5, 101.00, 2820.0, 0x7f7f1f }, // endcap ECAL
{ 2045.7, 8, 22.5, 101.00, -3022.0, 0x7f7f1f }, // endcap ECAL
{ 3000.0, 16, 0.0, 2658.5, -2658.5, 0xcf00 }, // outer HCAL
{ 3000.0, 8, 22.5, 702.25, 2826.0, 0xcf00 }, // endcap HCAL
{ 3000.0, 8, 22.5, 702.25, -4230.5, 0xcf00 }, // endcap HCAL
// radius,poligon order,angle degree,1/2 length,shift in z, color
};
/*
static CED_GeoCylinder geoCylinders[] = { // for Prototype
{ 180.0, 4, 45.0, 110.0, 0.0, 0xff }, // ECAL
{ 500.0, 4, 45.0, 250.0, 220., 0xff } // HCAL

*/
ced_geocylinders(sizeof(geoCylinders)/sizeof(CED_GeoCylinder),geoCylinders);
//------------------------------------------------------------------
One can put here as many cylinders as one want.
In any Processor:
void ********Processor::processEvent( LCEvent * evt ) {
// hit/point types are predefined as
// CED_HIT_POINT=0,
// CED_HIT_CROSS=1,
// CED_HIT_STAR=2,
//in loop: one can call either hit drawing or line drawing with functions:
// void ced_hit(float x,float y,float z,unsigned type,unsigned size,unsigned color);
// void ced_line(float x0,float y0,float z0,
// float x1,float y1,float z1,
// unsigned type,unsigned width,unsigned color);
to define colors is better use gimp - it gives that crasy numbers easily
// Possible type combinations:
// real call
for (int i=0; i<nn,i++){ // along hit/point collection or so
kcol = 0xf2290e;
// ECAL_LAYER-- mean hit will be switch on/off by keyboad key number 5 and
// will draw as CED_POINT i.e. .
ced_hit(cc_red[kk][nn].x,cc_red[kk][nn].y,cc_red[kk][nn].z,ECAL_LAYER,3,kcol);
kcol = 0x25cb17;
// HCAL_LAYER|2 -- mean hit will be switch on/off by keyboad key number 6 and
// will draw as CED_HIT_STAR i.e. *
ced_hit(cc_blue[kk][nn].x,cc_blue[kk][nn].y,cc_blue[kk][nn].z,HCAL_LAYER|2,3,kcol);
//or:
ced_line(x1,y1,z1,x2,y2,z2, CHADR_LAYER , 1, 0x7af774);
}
// after loop
ced_send_event(); // Does not clean up screen
// at the end of event
ced_draw_event(); // Make clean up screen before drawing
