Triangle

Class representing a geometric triangle. A triangle is defined by three Vector3 points (a, b, c) representing its vertices.

Methods

Triangle(const Vector3& a, const Vector3& b, const Vector3& c)

Constructor to create new triangle

a	first corner of the triangle	Vector3()
b	second corner of the triangle	Vector3()
c	third corner of the triangle	Vector3()

Triangle& set(const Vector3& a, const Vector3& b, const Vector3& c)

Sets the triangle's vertices by copying the given values

a	first corner of the triangle
b	second corner of the triangle
c	third corner of the triangle

Triangle& setFromPointsAndIndices(const vector<Vector3>& points, u32 i0, u32 i1, u32 i2)

Sets the triangle's vertices by copying the given array values

points	array with 3D points
i0	array index representing the first corner
i1	array index representing the second corner
i2	array index representing the third corner

Triangle& setFromAttributeAndIndices(const BufferAttribute& attribute, u32 i0, u32 i1, u32 i2)

Sets the triangle's vertices by copying the given attribute values

attribute	buffer attribute with 3D points data
i0	attribute index representing the first corner
i1	attribute index representing the second corner
i2	attribute index representing the third corner

Triangle clone() const

Returns a new triangle with copied values from this instance

Triangle& copy(const Triangle& triangle)

Copies the values of the given triangle to this instance
