Introdução¶
Freestyle is an edge/line-based non-photorealistic (NPR) rendering engine. It relies on mesh data and Z-depth information to draw lines on selected edge types. Various line styles can be added to produce artistic («hand drawn», «painted», etc.) or technical (hard line) looks.
The two operating modes: Python Scripting and Parameter Editor – allow a powerful diversity of line styles and results. Line styles such as Japanese big brush, cartoon, blueprint, thickness-with-depth are already pre-scripted in Python. The Parameter Editor mode allows intuitive editing of features such as dotted lines and easy setup of multiple line types and edge definitions. On top of all of that, with line style modifiers, the sky is the limit!
A grande imagem¶
- Activate Freestyle by the checkbox.
- Freestyle settings are located in the View Layer properties.
- One view layer can only have one view map. A view map holds the edge detection settings (Crease Angle, Culling toggle, Face Smoothness toggle, Material Boundaries toggle, Sphere Radius, and Kr Derivative Epsilon advanced options).
- A view map can have multiple Line Sets.
- Um conjunto de linha controla quais os tipos de linhas e seleções serão renderizados, e a partir de quais linhas presentes em sua cena.
- Each line set uses one line style (which can be shared between multiple Line Sets).
- A line style tells Freestyle how to render the linked Line Sets in terms of color, alpha, thickness and other aspects.
Limitações conhecidas¶
- Highly memory demanding: All mesh objects in a view layer are loaded at once.
- Only faced mesh objects are supported.
- Nenhuma das arestas nas intersecções entre as faces é detectada até o presente momento.
- Freestyle rendering results do not have any Z depth information.
- Câmeras panorâmicas não são suportadas.
