The recent optimization of the sculpt mode in Blender has significantly improved the software's performance, allowing for smoother interaction between brushes and the mesh. With reduced latency and greater processing efficiency, artists can now work with greater precision and without interruptions.
Problems in Brush Evaluation in Previous Versions
Before the optimization, brush evaluation in Blender was performed sequentially and by processing each individual vertex. This approach had several drawbacks:
- Inefficient memory access, which slowed down the process.
- Limitations in code optimization due to mixed data structures.
- Low processing speed on high-density models.
"Improving brush evaluation means reducing wait times and enhancing creativity in digital sculpting."
Restructuring of the Evaluation Process
To improve efficiency, a new system has been implemented in which brushes process multiple vertices in organized blocks within BVH nodes. This change has enabled:
- Faster and more precise deformations.
- Memory structure optimization for better GPU performance.
- Reduction of computational load in unnecessary calculations.
Fewer Redundant Calculations, More Speed
One of the main problems in previous versions was the amount of unnecessary calculations performed with each brush application. Now, with segmented evaluation in optimized blocks, redundant processes have been eliminated, achieving:
- Greater response speed in brush application.
- Lower resource consumption on CPU and GPU.
- A more intuitive and efficient workflow.
Use of SIMD and Improvement in Cache Memory
The optimization in Blender has also included the use of SIMD (Single Instruction, Multiple Data), a technique that allows multiple calculations in parallel across several vertices. Additionally, access to cache memory has been reorganized to:
- Avoid cache misses and improve data loading speed.
- Reduce latency in brush application.
- Optimize memory distribution for better performance on complex models.
Impact on User Experience
Thanks to these optimizations, brushes in Blender now respond more fluidly, eliminating perceptible delays even on models with millions of polygons. This allows digital artists to focus on their creativity without technical interruptions.
A Key Advancement for Digital Sculpting in Blender
The optimization in brush evaluation not only improves performance in the current version but also establishes a solid foundation for future advanced tools. With more efficient and precise processing, Blender continues to solidify itself as one of the most powerful options for digital creation.
