If `true` only the edges forming the silhouette of an object will be rendered.

bool vl::EdgeUpdateCallback::showCreases | ( |  | ) | const`[inline]`

If `true` only the edges forming the silhouette of an object will be rendered.

virtual void vl::EdgeUpdateCallback::operator() | ( | const Camera * | cam,
|  | Actor * | actor,
|  | Renderable * | renderable,
|  | const Shader * | shader,
|  | int | pass |
| ) |  |  | `[inline, virtual]`

Called upon callback execution.

Parameters:

  | cam | The camera used for the current rendering.
