11 Modeling surfaces with boundary representations and triangle meshes
This chapter covers
- Understanding the pros and cons of boundary representation modeling
- Seeing the triangle mesh as a particular case of a boundary representation
- Understanding the downsides of triangle mesh modeling
- Confidently using contouring algorithms: Marching cubes and dual contouring
- Understanding the trade-off between the model precision and model size
With signed distance functions, we model a 2D shape or a 3D body by introducing a rule. The function is negative inside the shape, positive outside, and 0 on the border. Most of the time, we’re not interested in anything apart from the border, which alone is enough to model a shape. So why bother modeling anything ...
