Overview

Bildeform is a powerful Blender addon designed to automatically generate bas-relief sculptures from 3D models. It employs advanced algorithms to create sophisticated bas-relief representations, enabling artists to quickly transform their 3D models into beautiful, low-relief sculptures.

Getting Started

1. Set Up Your Scene
   • Import or create your 3D model
   • Position your model as desired
   • Click "Set Camera" in the BilDeform panel (located in the N-panel)
   • Select your target object in the "Target" field
2. Configure Settings
   • Adjust Resolution X and Y (default: 2048x2048)
   • Set camera Focal Length
   • Choose Falloff Method
   • Select Mode Generation algorithm
3. Generate Bas Relief
   • Click "Generate Bas Relief"
   • Wait for the process to complete
   • A preview will appear in the panel
   • Adjust settings as needed

Features and Settings

Camera Settings

• Resolution X/Y: Define output resolution (1-16384 pixels)
• Focal Length: Adjust camera perspective
• Target: Select the object to track and generate relief from

Generation Options

• Falloff Method:
  • Method 1: Generates less precise and more rustic transitions
  • Method 2: Produces smoother, finer, and more elegant transitions
• Mode Generation:
  1. Frankot-Chellappa
     • Best for simpler models
     • Faster processing
     • Smoother results
  2. Kernel Approach
     • Better for complex models
     • Preserves more detail
     • Handles discontinuities better

Limitations and Recommendations

Algorithm Selection

• Frankot-Chellappa Algorithm:
  • Optimized for simpler models with continuous surfaces
  • Performs best when processing objects with minimal surface discontinuities
  • Faster processing time but less robust for complex geometry
• Kernel Approach Algorithm:
  • Specifically designed to handle complex surface geometry
  • Better preservation of fine details and sharp transitions
  • More computationally intensive but handles discontinuities effectively

Best Practices

• Parent multiple objects to Empty or main object for unified control
• Set camera target to parent object for consistent tracking
• Frequent saving prevents loss of work during complex operations
• Apply all modifiers before generation to ensure accurate geometry
