UnrealVis: A Testing Laboratory of Optimization Techniques in Unreal Engine for Scientific Visualization
🤖 AI Summary
This work addresses the longstanding challenge in scientific visualization of balancing rendering performance with visual fidelity for large-scale 3D datasets, compounded by the high barrier to entry of conventional tools. The authors present an interactive benchmarking platform built on Unreal Engine that systematically implements and organizes 22 optimization techniques into six cohesive families. These techniques are integrated into the engine’s subsystems, enabling configurable combinations, real-time telemetry, and A/B comparisons. By leveraging mechanisms such as Nanite, multi-level level-of-detail (LOD), and culling algorithms—combined with integrated performance profiling and expert evaluation workflows—the platform demonstrates significant gains in optimization efficiency. Validation on ribosome structures and volumetric flow fields confirms its effectiveness in helping users maintain high visual fidelity under strict performance constraints.
📝 Abstract
Visualizing large 3D scientific datasets requires balancing performance and fidelity, but traditional tools often demand excessive technical expertise. We introduce UnrealVis, an Unreal Engine optimization laboratory for configuring and evaluating rendering techniques during interactive exploration. Following a review of 55 papers, we established a taxonomy of 22 optimization techniques across six families, implementing them through engine subsystems such as Nanite, Level of Detail(LOD) schemes, and culling. The system features an intuitive workflow with live telemetry and A/B comparisons for local and global performance analysis. Validated through case studies of ribosomal structures and volumetric flow fields, along with an expert evaluation, UnrealVis facilitates the selection of optimization combinations that meet performance goals while preserving structural fidelity.
