vuo.point

These nodes are for doing calculations with 2D, 3D, and 4D points and vectors.

Example compositions:

• Is Mouse Within Rectangle: Displays a rectangle, and highlights it when the mouse is within it.
• Make Spiral: Animates a spiral using simple trigonometric expressions.
• Make Terrain: Calculates and displays a 3D terrain using simple trigonometric expressions.

Nodes:

• Add Points (vuo.point.add): Calculates the sum of the points.
• Measure Distance between Points (vuo.point.distance): Finds the distance between two points.
• Get 2D Point Values (vuo.point.get.VuoPoint2d): Gives the coordinates of a 2D point.
• Get 3D Point Values (vuo.point.get.VuoPoint3d): Gives the coordinates of a 3D point.
• Get 4D Point Values (vuo.point.get.VuoPoint4d): Gives the coordinates of a 4D point.
• Make 2D Point (vuo.point.make.VuoPoint2d): Creates a 2D point from coordinates.
• Make 3D Point (vuo.point.make.VuoPoint3d): Creates a 3D point from coordinates.
• Make 4D Point (vuo.point.make.VuoPoint4d): Creates a 4D point from coordinates.
• Make Points along Curve (vuo.point.make.curve): Calculates a list of points along an easing curve.
• Make Parametric Points (vuo.point.make.parametric): Creates points that form a shape defined by parametric math expressions.
• Make Parametric Grid (vuo.point.make.parametric.grid): Creates points that form a shape defined by parametric math expressions.
• Scale Point (vuo.point.multiply.scalar): Multiplies each coordinate of the point by a scale factor.
• Normalize Point (vuo.point.normalize): Outputs a unit vector (length of 1) in the same direction as the input vector.
• Sort Points by Distance (vuo.point.sort.distance): Puts a list of points in order of nearest to farthest from a target point.
• Sort Points by W Distance (vuo.point.sort.distance.w.VuoPoint4d): Puts a list of points in order of nearest to farthest from a target point, comparing only the difference in w-coordinates.
• Sort Points by X Distance (vuo.point.sort.distance.x): Puts a list of points in order of nearest to farthest from a target point, comparing only the distance along the x-axis.
• Sort Points by Y Distance (vuo.point.sort.distance.y): Puts a list of points in order of nearest to farthest from a target point, comparing only the distance along the y-axis.
• Sort Points by Z Distance (vuo.point.sort.distance.z): Puts a list of points in order of nearest to farthest from a target point, comparing only the distance along the z-axis.
• Subtract Points (vuo.point.subtract): Calculates a minus b (a-b).
• Is within Box (vuo.point.within.box): Outputs true if the point is within a given 3D bounding box.
• Is within Circle (vuo.point.within.circle): Outputs true if the point is within a given circle.
• Is within Rectangle (vuo.point.within.rectangle): Outputs true if the point is within a given rectangle (2D bounding box).
• Is within Sphere (vuo.point.within.sphere): Outputs true if the point is within a given sphere.
