Types ¶
type Line2D ¶
type Line2D struct {
// contains filtered or unexported fields
}
Line2D represents a line segment
func (Line2D) ClosestPointOnLine ¶
func (Line2D) GetEndPoint ¶
GetEndPoint returns the end point of the line segment
func (Line2D) GetStartPoint ¶
GetStartPoint returns the starting point of the line segment
func (Line2D) Intersection ¶
Intersection finds where two lines intersect https://stackoverflow.com/questions/563198/how-do-you-detect-where-two-line-segments-intersect
func (Line2D) Intersects ¶
Intersects determines whether two lines intersect eachother
func (Line2D) ScaleOutwards ¶
ScaleOutwards multiplies the current length of the line by extending it out further in the two different directions it's heading
type Line3D ¶
type Line3D struct {
// contains filtered or unexported fields
}
Line3D is a series of ordered points that make up a line segment through 3D space.
func (Line3D) ClosestPointOnLine ¶
func (Line3D) GetEndPoint ¶
GetEndPoint returns the end point of the line segment
func (Line3D) GetStartPoint ¶
GetStartPoint returns the starting point of the line segment
func (Line3D) ScaleOutwards ¶
ScaleOutwards assumes line segment 3d is only two points multiplies the current length of the line by extending it out further in the two different directions it's heading
type Orientation ¶
type Orientation int
const ( Colinear Orientation = iota Clockwise Counterclockwise )
type Plane ¶
type Plane struct {
// contains filtered or unexported fields
}
func NewPlaneFromPoints ¶
type Shape ¶
Shape is a flat (2D) arrangement of points.
func (Shape) GetBoundingBoxDimensions ¶
func (Shape) IsInside ¶
IsInside returns true if the point p lies inside the polygon[] with n vertices
func (Shape) Less ¶
Less determines which point is more oriented more clockwise from the center than the other
func (Shape) RandomPointInShape ¶
RandomPointInShape returns a random point inside of the shape
func (Shape) Rotate ¶
Rotate will rotate all points in the shape around the pivot by the passed in amount
func (Shape) Split ¶
Split figures out which points land on which side of the vertical line and builds new shapes from that
