Eve is a ROOT module based on experiment-independent part of the ALICE event display developed in cooperation between ALICE offline project and ROOT during the last two years. It has been used in ALICE for more than a year to perform high-level event visualization, debugging of simulation and reconstruction code as well as for raw-data visualization.

Papers describing Eve (older ones still using the old name - Reve):

• EVE - Event Visualization Environment of the ROOT framework, presented at ACAT 2008.
• Event Visualization Environment of the ALICE experiment, presented at ROOT Workshop 2007.
• Raw-data display and visual reconstruction validation in ALICE, presented at CHEP 2007.

Eve is built on top of ROOT's GUI, GL and GED infrastructure and delivers the following main features:

• Base-classes for representation of visual objects that can be presented in list-tree views, object-editors and rendered via OpenGL (TEveElement and sub-classes).
• Application manager class TEveManager for top-level management of elements, GUI components, geometries and events;
• Classes for presentation of full TGeo geometries (TEveGeoNode and TEveGeoTopNode) as well as of simplifed geometries via extraction of shape-data (TEveGeoShape).

  

• Classes for presentation of trajectories or tracks (TEveTrack, TEveTrackPropagator) and hits or clusters (TEvePointSet, TEvePointSetArray).

  

• Base-classes for presentation of raw-data or digits (TEveDigitSet, TEveQuadSet and TEveBoxSet). A collection of objects can be assigned common signal-to-color mapping (TEveRGBAPelette) and surrounding frame (TEveFrameBox).

  

• Base-classes for 2D projections with dynamically controllable fish-eye magnification of the vertex region (TEveProjectionManager and TEveProjection). Tracks, points and geometries can be projected automatically. R-phi and Rho-z projections are currently supported.

  

• TriangleSet class for presentation of generic triangle meshes.
