cubos::core::geom::Box struct
#include <core/geom/box.hpp>

Represents a box shape.

Public static functions

static void enclosingFaces(int vertexIndex, int faces[3]): Computes the enclosing faces of the corner.
static void edges(glm::ivec2 edges[12]): Computes the edges of a box. An edge is a pair of the corner indexes that compose it.
static void edgeAdjacentFaces(int edgeIndex, int faces[2]): Computes the faces adjacent to an edge.
static void faceEdges(int faceIndex, int edges[4]): Computes the edges of a face.
static void faces(glm::ivec4 faces[6]): Computes the faces with regards to the corner indexes that compose them. In conter-clock wise winding order.
static void faceNormals(glm::vec3 normals[6]): Computes the normal of each face. Same order as faces.

Public functions

void diag(glm::vec3 corners[2]) const: Computes two opposite corners of the box on the major diagonal.
void corners4(glm::vec3 corners[4]) const: Computes four corners of the box, one for each diagonal.
void corners(glm::vec3 corners[8]) const: Computes the eight corners of the box, opposite corners are adjacent in the array.

Public variables

glm::vec3 halfSize: Half size of the box.

Function documentation

static void cubos::core::geom::Box::enclosingFaces(int vertexIndex, int faces[3])

Computes the enclosing faces of the corner.

Parameters
vertexIndex	Index of the corner, according to the returned by corners.
faces	Array to store the three face indexes in, according to the returned by faces.

static void cubos::core::geom::Box::edges(glm::ivec2 edges[12])
