SDF.R
Pioneering the Next Generation of Blender Modeling

SDF.R is a groundbreaking engine designed to bring the power of Signed Distance Fields (SDF) to Blender with unprecedented speed. As the first-ever add-on in its class to integrate a custom Rust-GPU backend, SDF.R sets a new standard for performance and topological quality.

STABLE & HIGH PERFORMANCE
Main Engine: Marching Cubes (MC) | Experimental Feature: Dual Contouring (DC)
SDF.R primarily features a Marching Cubes (MC) engine that combines stability with high performance.

Looking toward future development, it also includes an experimental GPU-accelerated Dual Contouring (DC) engine for users seeking cutting-edge sharpness. By utilizing a custom QEF (Quadratic Error Function) solver, this experimental DC mode preserves sharp corners and creases (such as box edges) that tend to be smoothed out in conventional SDF environments.

However, since the MC engine takes priority, please understand that DC is strictly an experimental implementation and may be unstable.

What’s New in V15.9.x
Local Pipeline Disk Cache & Driver Warm-up: No more mid-sculpt freezes! Compiled shader pipelines are cached locally, cutting subsequent startup times down to just 2-3 seconds.
Mathematical scale synchronization: Supports multiplicative scaling. Primitives scaled or stretched in Blender match the real-time viewport preview and final baked mesh 1:1.
Non-Destructive Deform Stack: Chain Twist, Bend, and Taper in any order. The mesh generation features stretch-distortion correction to prevent geometry tearing under high deformation.
Boolean Subtraction Material Painting: Carved surfaces automatically inherit the Color, Roughness, and Metallic properties of the cutting tool object, enabling interactive multi-material sculpting.
iGPU Low-VRAM Safeguard: The engine dynamically checks your hardware boundaries (such as max_storage_buffer_binding_size) on startup and adjusts block sizes to prevent GPU-related crashes.
Key Features
World’s First Rust-GPU Engine: Breaking new ground in Blender development. SDF.R utilizes a dedicated Rust backend for unparalleled calculation speeds.
Real-time GPU Previews: Instant, interactive feedback via Blender’s GPU module. What you see is what you get.
Advanced Topology Options: Choose between stable Marching Cubes (MC) for organic sculpting, or Dual Contouring (DC) for sharp mechanical features.
Seamless Dynamic Fusion: Effortlessly blend organic curves or sharp mechanical joins with adjustable smoothing.
Advanced Layout Stacking: Create complex patterns with Mirror, Radial, Spiral, Grid, and Jitter modifiers in one unified stack.
