GQLink vs. Geant4 comparison plots - with crossing planes¶

General settings¶

• stepMax: 20 mm
• deltaIntersection: 1e-5 mm
• deltaChord: 0.25 mm (not relevant for GQLink)
• deltaOneStep: 0.01 mm (overriden by epsilon)
• trackMaxLen: 1 km

epsilon = 1e-6¶

epsilon = 1e-7¶

epsilon = 1e-8¶

Callgraphs¶

General settings¶

• epsilon: 1e-5
• stepMax: 20 mm
• deltaIntersection: 1e-5 mm
• deltaChord: 0.25 mm (not relevant for GQLink)
• deltaOneStep: 0.01 mm (overriden by epsilon)
• trackMaxLen: 100 m

• GQLink callgraph - 150 planes - Raw profiler output
• Geant4 callgraph - 150 planes - Raw profiler output

• GQLink callgraph - 2 planes - Raw profiler output
• Geant4 callgraph - 2 planes - Raw profiler output

Replacement of AccurateAdvance inside EstimateIntersectionPoint¶

General settings¶

• stepMax: 20 mm
• epsilon: 1e-6
• deltaIntersection: 1e-5 mm
• deltaChord: 0.25 mm (not relevant for GQLink)
• deltaOneStep: 0.01 mm (overriden by epsilon)
• trackMaxLen: 1 km
