Implementations§
source§impl Triangle
impl Triangle
pub fn as_ptr(&self) -> *mut graphene_triangle_t
sourcepub unsafe fn from_glib_ptr_borrow<'a>(
ptr: *const graphene_triangle_t
) -> &'a Self
pub unsafe fn from_glib_ptr_borrow<'a>( ptr: *const graphene_triangle_t ) -> &'a Self
Borrows the underlying C value.
sourcepub unsafe fn from_glib_ptr_borrow_mut<'a>(
ptr: *mut graphene_triangle_t
) -> &'a mut Self
pub unsafe fn from_glib_ptr_borrow_mut<'a>( ptr: *mut graphene_triangle_t ) -> &'a mut Self
Borrows the underlying C value mutably.

impl Triangle
sourcepub fn contains_point(&self, p: &Point3D) -> bool
pub fn contains_point(&self, p: &Point3D) -> bool
sourcepub fn barycoords(&self, p: Option<&Point3D>) -> Option<Vec2>
pub fn barycoords(&self, p: Option<&Point3D>) -> Option<Vec2>
Computes the barycentric coordinates
of the given point p
.
The point p
must lie on the same plane as the triangle self
; if the
point is not coplanar, the result of this function is undefined.
If we place the origin in the coordinates of the triangle’s A point,
the barycentric coordinates are u
, which is on the AC vector; and v
which is on the AB vector:
The returned Vec2
contains the following values, in order:
res.x = u
res.y = v
p
a Point3D
Returns
true
if the barycentric coordinates are valid
res
return location for the vector with the barycentric coordinates
sourcepub fn bounding_box(&self) -> Box
pub fn bounding_box(&self) -> Box
sourcepub fn uv(
&self,
p: Option<&Point3D>,
uv_a: &Vec2,
uv_b: &Vec2,
uv_c: &Vec2
) -> Option<Vec2>
pub fn uv( &self, p: Option<&Point3D>, uv_a: &Vec2, uv_b: &Vec2, uv_c: &Vec2 ) -> Option<Vec2>
Computes the UV coordinates of the given point p
.
The point p
must lie on the same plane as the triangle self
; if the point
is not coplanar, the result of this function is undefined. If p
is None
,
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
See also: barycoords()
p
a Point3D
uv_a
the UV coordinates of the first point
uv_b
the UV coordinates of the second point
uv_c
the UV coordinates of the third point
Returns
true
if the coordinates are valid
res
a vector containing the UV coordinates
of the given point p
