Rendering Engine v0.2.9

Rendering Engine v0.2.9

This release focuses on resource-processing performance, memory efficiency, and application startup time, with significant improvements to image handling and font atlas generation.

Highlights

• Reworked ImageData storage to use contiguous std::vector-based memory.
• Optimized RGB and RGBA image loading paths.
• Replaced per-pixel image copying with row-wise contiguous memory operations.
• Significantly improved texture loading and font atlas generation performance.
• Reduced SceneManager and overall application initialization times.
• Added a dedicated TextureBenchmark application for Release-mode performance evaluation.
• Validated the improvements on both Windows and FreeBSD using representative PNG/JPG assets and multilingual font atlases.

Performance Improvements

Windows

• Texture loading: 343.54 ms → 113.88 ms
• Font atlas preload: 265.88 ms → 72.17 ms
• SceneManager initialization: 676.32 ms → 204.86 ms
• CoreApplication initialization: 1669 ms → 518 ms

FreeBSD

• Texture loading: 336.32 ms → 179.40 ms
• Font atlas preload: 170.88 ms → 140.67 ms
• SceneManager initialization: 550.15 ms → 244.95 ms
• CoreApplication initialization: 665 ms → 356 ms

The main performance gains come from eliminating per-pixel operations and improving memory locality in the image-processing pipeline. The resulting improvements reduce resource-loading overhead and application startup time across supported platforms.
