Member Function Documentation

getNormal()

glm::vec3 Saga::Geometry::Triangle::getNormal

(

)

Get the normal of this triangle.

Returns

glm::vec3 the normal of this triangle in the direction of cross(b-a, c-a).

toBarycentric()

glm::vec3 Saga::Geometry::Triangle::toBarycentric

(

const glm::vec3

pos

)

Convert a point from cartesian to barycentric coordinate with respect to the current triangle.

Parameters

pos	the position in cartesian space.

Returns

glm::vec3 the barycentric coordinate (u,v,w) such that p projected onto the plane of a,b,c is = u * a + v * b + w * c.

toUV()

glm::vec2 Saga::Geometry::Triangle::toUV

(

const glm::vec3

pos

)

Convert a point from cartesian to UV coordinate.

Parameters

pos	the position in cartesian space.

Returns

glm::vec3 the barycentric coordinate (u,v,w) such that p = u * a + v * b + w * c.
