Point (vuo.point)

Nodes for doing calculations with 2D, 3D, and 4D points and vectors.

See also the vuo.math node set, which has several nodes that work with points.

Replicating or animating an object along a path

Some of the nodes in this node set output a list of points:

• Make Points along Cube Edges
• Make Points along Line
• Make Points along Oval
• Make Points along Spline
• Make Points in 3D Grid
• Make Phyllotaxis Points
• Make Parametric Points
• Make Parametric Grid Points

You can connect the output of these nodes to the Copy Layer or Copy 3D Object node to create a series of objects along a path.

Alternatively, you can connect the output of these nodes to the Cycle through List node, then connect that to Transform Layer or Transform 3D Object to animate an object moving along a path.

Example compositions:

• Display Grid of Objects: Displays a 2D grid of cones with a little springiness.
• Draw Points along Curve: Plots the points along an easing curve. Click to change the type of curve.
• Draw Points along Spline: Plots points along a spline, varying the continuity, tension, and bias of the spline.
• Is Mouse within Rectangle: Displays a rectangle, and highlights it when the mouse is within it.
• Make Smooth Terrain: Calculates and displays a 3D terrain using simple trigonometric expressions.
• Make Spiral: Animates a spiral using simple trigonometric expressions.
• Travel through Infinite Grid: Moves a continually replenishing 3D grid past the camera.
