Overview ¶
Package xyz contains operations in 3d coordinate space. Each layout must have 3 ordinates (and thus each coordinate) it is assumed that x,y,z are ordinates with indexes 0,1,2 respectively
Index ¶
- func Distance(point1, point2 geom.Coord) float64
- func DistanceLineToLine(line1Start, line1End, line2Start, line2End geom.Coord) float64
- func DistancePointToLine(point, lineStart, lineEnd geom.Coord) float64
- func Equals(point1, other geom.Coord) bool
- func VectorDot(v1Start, v1End, v2Start, v2End geom.Coord) float64

Functions ¶
func Distance ¶
Distance calculates the distance between the two coordinates in 3d space.
Example ¶
p1 := geom.Coord{0, 0, 0} p2 := geom.Coord{10, 0, 0} distance := xyz.Distance(p1, p2) fmt.Println(distance)
Output: 10
func DistanceLineToLine ¶
DistanceLineToLine computes the distance between two 3D segments
Example ¶
line1Start := geom.Coord{10, 0, 10} line1End := geom.Coord{10, 0, -10} line2Start := geom.Coord{0, 0, 10} line2End := geom.Coord{0, 0, -10} distance := xyz.DistanceLineToLine(line1Start, line1End, line2Start, line2End) fmt.Println(distance)
Output: 10
func DistancePointToLine ¶
DistancePointToLine calculates the distance from point to a point on the line
Example ¶
p1 := geom.Coord{0, 0, 0} lineStart := geom.Coord{10, 0, 10} lineEnd := geom.Coord{10, 0, -10} distance := xyz.DistancePointToLine(p1, lineStart, lineEnd) fmt.Println(distance)
Output: 10
func Equals ¶
Equals determines if the two coordinates have equal in 3d space
Example ¶
p1 := geom.Coord{0, 0} p2 := geom.Coord{10, 0} distance := xyz.Equals(p1, p2) fmt.Println(distance)
Output: false
func VectorDot ¶
func VectorDot(v1Start, v1End, v2Start, v2End geom.Coord) float64
VectorDot calculates the dot product of two vectors
Example ¶
v1 := geom.Coord{0.44022007739138613, 0.833525569726002, 0.49302724302422873} v2 := geom.Coord{0.05162589254031058, 0.977176382882891, 0.8789402270478548} v3 := geom.Coord{0.7534455876162328, 0.6173555367190986, 0.27126435983727104} v4 := geom.Coord{0.8452219342333697, 0.5825792503932398, 0.4764854482064663} dot := xyz.VectorDot(v1, v2, v3, v4) fmt.Println(dot)
Output: 0.038538086185549936
func VectorLength ¶
func VectorLength(vector geom.Coord) float64
VectorLength calculates the length of the vector from 0,0,0 to vector
Example ¶
v1 := geom.Coord{0.050809870984833916, 0.31035561291492797, 0.001499306503938036} length := xyz.VectorLength(v1) fmt.Println(length)
Output: 0.3144908542029304
func VectorNormalize ¶
func VectorNormalize(vector geom.Coord) geom.Coord
VectorNormalize creates a coordinate that is the normalized vector from 0,0,0 to vector
Example ¶
v1 := geom.Coord{0.9807055460429551, 0.8643056316322373, 0.08720913878428183} normalized := xyz.VectorNormalize(v1) fmt.Println(normalized)
Output: [0.7485619198694545 0.6597151260937918 0.06656579094706616]
