Triangle.getUv

bool getUv(graphene.point3_d.Point3D p,  graphene.vec2.Vec2 uvA,  graphene.vec2.Vec2 uvB,  graphene.vec2.Vec2 uvC,  out  graphene.vec2.Vec2 res)

Computes the UV coordinates of the given point p.

The point p must lie on the same plane as the triangle t; if the point is not coplanar, the result of this function is undefined. If p is null, the point will be set in (0, 0, 0).

The UV coordinates will be placed in the res vector:

res.x = u
res.y = v

Parameters

`p`	a #graphene_point3d_t
`uvA`	the UV coordinates of the first point
`uvB`	the UV coordinates of the second point
`uvC`	the UV coordinates of the third point
`res`	a vector containing the UV coordinates of the given point `p`

Returns

true if the coordinates are valid
