Viewer and UI integration (Geant4.9.3)

Viewer and UI integration

This was before Big change in Geant4 Qt Driver

• Integration of viewers into UI
• 

Viewer and UI integration (History)

What's new ?

• History/Cout/Help are now integrate into UI
• Viewers can be view as Tab's
• We can filter Cout messages
• Easy help tree to find a command and its help
• Still old things... : Make videos...

Rotations

Two rotation mode are available : Theta/Phi rotation and 'google earth' like

• Theta/Phi rotation : The default mode
  • Ensure the up vector to be vertical direction
  • Impossible to reach some points
  • 'Not intuitive' behaviour on some angles
• 'google earth like' rotation
  • Up vector is NOT vertical
  • Could reach all volume angles
  • More 'intuitive' rotation mode

Keyboard Shortcuts

All move/rotate/zoom commands are available with Keyboard shortcuts. Ex :

• ALT + Click and move mouse : rotate volume (google like)
• Click and move mouse : rotate volume
• CTRL + Click and mouse move : zoom in/out
• SHIFT + Click and mouse move : move camera point of view
• Arrow : move volume
• '+'/'-' : move volume toward/forward
• SHIFT + Arrows : rotate volume in phi/theta
• SHIFT + Arrows : rotate volume in vertical/horizontal
• CTRL + '+'/'-' : zoom into volume
• H : reset view to initial position
• SPACE : Start/Pause video recording
• RETURN : Stop video recording

Speed improvments in OpenGL drivers

Loose time when moving a component is in visualization part. Thank to Shark (mac OSX), I identify two bootle neck : glBegin (47% of OGL time) and glFlush (44%). After some code optimisations :

Mac OSX 10.5 : Immediate Mode

	First draw time (sec)	Rotation (fps)
Geant 4.9.3	5	0,46
Geant 4.9.4	6	0,53

Mac OSX 10.6 : Immediate Mode

Geant 4.9.3	5	0,6
Geant 4.9.4	6	0,6

Mac OSX 10.5 : Stored Mode

Geant 4.9.3	94	1,2
Geant 4.9.4	72 (x1,3)	2,66 (x2,2)

Mac OSX 10.6 : Stored Mode

Geant 4.9.3	13	3,73
Geant 4.9.4	11 (x1,2)	5,3 (x1,43)

Speed improvments in OpenGL drivers

Make posters

• Olders Geant4 version can only export up to screen size pictures
• How could we export bigger file in order to print/exchange screenshots/publish/make poster ?
• Thanks to gl2ps we could now export up to maximum graphic card capacity size (Ex: Up to 8192 x 8192 on MacBook Pro)
• How does it work ?

Make posters

Some G4 new commands :

• /vis/ogl/set/printMode (vectored or pixmap)
• /vis/ogl/set/printFilename (default G4OpenGL_XX)
• /vis/ogl/set/printSize (< maximum graphic card capacity)
• /vis/ogl/printEPS
