122 | // | |
123 | // A QUICK Overview of the Event Display functions | |
124 | // =============================================== | |
125 | // | |
126 | // The event display can ve invoked by executing the macro "display.C" | |
127 | // A canvas like in the picture below will appear. | |
128 | // | |
129 | // On the left side of the canvas, the following buttons appear: | |
130 | // *Next* to move to the next event | |
131 | // *Previous* to move to the previous event | |
132 | // *Top View* to display a top view of the current event | |
133 | // *Side View* to display a side view of the current event | |
134 | // *Front View* to display a front view of the current event | |
135 | // *All Views* to display front/side/top/30-30 views of the current event | |
136 | // *OpenGL* to use OpenGl to view the current event. | |
137 | // Note that OpenGL cannot be used across the network. | |
138 | // Before using OpenGL, load the GL libraries | |
139 | // by executing the macro GL.C (in $ROOTSYS/macros/GL.C. | |
140 | // Once in GL, click the HELP button of the GL canvas. | |
141 | // *X3D* to use X3D to view the current event (Unix only). | |
142 | // Once in X3D, type M to see the list of all possible options. | |
143 | // for example type J to zoom, K to unzoom | |
144 | // use the mouse to rotate. | |
145 | // *Pick* Select this option to be able to point on a track with the | |
146 | // mouse. Once on the track, use the right button to select | |
147 | // an action. For example, select SetMarkerAttributes to | |
148 | // change the marker type/color/size for the track. | |
149 | // *Zoom* Select this option (default) if you want to zoom. | |
150 | // To zoom, simply select the selected area with the left button. | |
151 | // *UnZoom* To revert to the previous picture size. | |
152 | // | |
153 | // slider R On the left side, the vertical slider can be used to | |
154 | // set the default picture size. | |
155 | // slider pcut At the top of the canvas, a slider can be used to change | |
156 | // the momentum cut (or range) to display tracks. | |
157 | // slider eta On the right side of the canvas, a vertical slider can be used | |
158 | // to specify a rapidity range for the tracks. | |
159 | // | |
160 | // When you are in Zoom mode, you can click on the black part of the canvas | |
161 | // to select special options with the right mouse button. | |
162 | // This will display a pop-up menu with items like: | |
163 | // *Disable detector* | |
164 | // *Enable detector*, etc. | |
165 | // For example select "Disable detector". You get a dialog box. | |
166 | // Diable detector TRD for example. | |
167 | // | |
168 | // When you are in pick mode, you can "Inspect" the object pointed by the mouse. | |
169 | // When you are on a track, select the menu item "InspectParticle" | |
170 | // to display the current particle attributes. | |
171 | // | |
172 | // You can activate the Root browser by selecting the Inspect menu | |
173 | // in the canvas tool bar menu. Then select "Start Browser" | |
174 | // This will open a new canvas with the browser. At this point, you may want | |
175 | // to display some histograms (from the Trees). Go to the "File" menu | |
176 | // of the browser and click on "New canvas". | |
177 | // In the browser, click on item "ROOT files" in the left pane. | |
178 | // Click on galice.root. | |
179 | // Click on TH | |
180 | // Click on TPC for example | |
181 | // Click on any variable (eg TPC.fX) to histogram the variable. | |
182 | // | |
183 | // If you are lost, you can click on HELP in any Root canvas or browser. | |
