Class: Gfx3BoundingBox

The `Gfx3BoundingBox` class represents a 3D bounding box and provides various methods for manipulating and calculating properties of the box.

Constructors

• new Gfx3BoundingBox(min: vec3, max: vec3): Gfx3BoundingBox
  The constructor.
  
  • min: The minimum point of the bounding box.
    
  • max: The maximum point of the bounding box.
    

Methods

• fromVertices(vertices, vertexStride: number): void
  The "fromVertices" function takes an array of vertices and calculates the new minimum and maximum values.
  
  • vertices: The `vertices` parameter is an array of numbers representing the coordinates of the points of a shape. Each triplets of numbers represents the x, y and z coordinates of a point.
    
  • vertexStride
    
    
• getCenter(): vec3
  The "getCenter" function calculates the center point of the box.
  
  
• getPerimeter(): number
  The "getPerimeter" function calculates and returns the perimeter of the box.
  
  
• getRadius(): number
  The "getRadius" function calculates the radius of a circumscribed circle to the box.
  
  
• getSize(): vec3
  The "getSize" function calculates and returns the width, height and depth of the box.
  
  
• getVolume(): number
  The "getVolume" function calculates the volume of a the box.
  
  
• intersectBoundingBox(aabb: Gfx3BoundingBox): boolean
  The "intersectBoundingBox" function checks if two bounding boxes intersect.
  
  • aabb: The parameter "aabb" is the box to check for intersection.
    
    
• isPointInside(x: number, y: number, z: number): boolean
  The "isPointInside" function checks if a given point is inside the box.
  
  • x: The x-coordinate of the point.
    
  • y: The y-coordinate of the point.
    
  • z: The z-coordinate of the point.
    
    
• merge(aabb: Gfx3BoundingBox): Gfx3BoundingBox
  The "merge" function takes a `Gfx3BoundingBox` object as input and returns a new `Gfx3BoundingBox` that represents the union of the two boxes.
  
  • aabb: The `aabb` parameter is the box to merge.
    
    
• reset(): void
  The "reset" function sets the "min" and "max" values to [0, 0, 0].
  
  
• setMax(max: vec3): void
  The "setMax" function sets the maximum value.
  
  • max: The `max`point of the box.
    
    
• setMin(min: vec3): void
  The "setMin" function sets the minimum value.
  
  • min: The `min` point of the box.
    
    
• transform(matrix: mat4): Gfx3BoundingBox
  The "transform" function takes a matrix and transforms the bounding box points, returning a new transformed bounding box.
  
  • matrix: The `matrix` parameter is a 4x4 transformation matrix. It is used to transform the points of a bounding box.
    
    
• createFromCenter(x: number, y: number, z: number, w: number, h: number, d: number): Gfx3BoundingBox
  The "createFromCenter" is a static method that creates a new instance of "Gfx3BoundingBox".
  
  • x: The x-coordinate of the center of the bounding box.
    
  • y: The y-coordinate of the center of the bounding box.
    
  • z: The z-coordinate of the center of the bounding box.
    
  • w: The width of the bounding box.
    
  • h: The height of the bounding box.
    
  • d: The depth of the bounding box.
    
    
• createFromCoord(x: number, y: number, z: number, w: number, h: number, d: number): Gfx3BoundingBox
  The "createFromCoord" is a static method that creates a new instance of "Gfx3BoundingBox".
  
  • x: The x-coordinate of the bottom-left-front corner of the bounding box.
    
  • y: The y-coordinate of the bottom-left-front corner of the bounding box.
    
  • z: The z-coordinate of the bottom-left-front corner of the bounding box.
    
  • w: The width of the bounding box.
    
  • h: The height of the bounding box.
    
  • d: The depth of the bounding box.
    
    
• merge(aabbs: Gfx3BoundingBox[]): Gfx3BoundingBox
  The "merge" function takes an array of `Gfx3BoundingBox` objects as input and returns a new `Gfx3BoundingBox` that represents the union of boxes.
  
  • aabbs: The `aabbs` parameter is an array of box to merge.
