Freestyle

Panel:

Propiedades ‣ Capa de visualización ‣ Freestyle

There is only one view map per view layer. It controls the edge detection parameters. Freestyle can be enabled/disabled per View Layer by toggling the checkbox in the panel header.

Capa de visualización: El panel Freestyle.

Modo de control

Which detected edges are actually rendered, and how, can be controlled either through:

Modo Editor de parámetros:

Lines are rendered via parameters defined in a user-friendly interface to define and control Line Sets and line styles.

A view map (hence a view layer) can have multiple Line Sets, and each line set is linked to one line style.

Modo Scripts de Python:

Lines are rendered via Python scripting, powerful but complex.

Caché de mapa de vista

An option to reuse a previously computed view map for subsequent rendering. The cache is automatically updated when the mesh geometry of the input 3D scene has been changed.

This functionality offers a major performance boost for Freestyle animation rendering when the camera-space mesh geometry is static, as well as for repeated still renders with updates of line stylization options.

Although the View Map Cache checkbox is a view layer option, the cache memory is shared by all view layers and scenes. This means that if Freestyle is used for two or more view layers (possibly in different scenes through the Compositor), then the cached view map for one view layer is replaced by a new view map for another view layer and hence no performance gain is expected.

Como pasada de procesamiento

Cuando esta opción esté activa, las líneas de Freestyle no aparecerán inmediatamente visibles sobre la imagen procesada. En cambio, serán procesadas como una Pasada de procesamiento independiente, que podrá ser luego compuesta con la imagen procesada mediante el uso de un nodo Superponer con alfa.

Detección de bordes

Ángulo de plegado

If two adjacent faces form an angle less than the defined Crease Angle, the edge between them will be rendered when using Crease edge type selection in a line set. The value also affects Silhouette edge type selection.

Descartar

Ignore the edges that are out of view. (Saves some processing time and memory, but may reduce the quality of the result in some cases.)

Suavizado de caras

Takes Smooth Shading into account for edges calculation.

Radio de esfera

Affects the calculation of curvatures for Ridge, Valley and Suggestive Contour edge type selection in a line set. The curvature at each vertex is computed by averaging the shape of the surface within the specified radius. Increasing the value reduces noise and detail.

Épsilon de derivada de Kr

Controls the threshold on the minimum rate of change of curvature used to filter the output of the Suggestive Contour edge type selection. Increasing the value reduces the amount of rendered lines, starting from smoother areas of the object (further information in this pdf).
