Instead of defining each point along a curve or shape, curves in Genetica are defined by a small number of points that Genetica uses to construct smooth curves.
Curves are defined by control points and tangent points. |
Control points specify points that the curve must pass through. Drag control points to make a curve pass through a different area.
|
Tangent points control the angle a curve will take as it passed through the corresponding control point. Move a tangent point to modify a curve's slope. |
The distance between a tangent point and its corresponding control point determines the extent to which the curve will attempt to conform to it. |
Within the Canvas node, there are various ways to create curves that can be directly modified using the handles shown above, such as:
| • | Use the Draw tool to create a new curve. |
Such curves will also appear within the Texture Synthesis dialog.
