Definition

BarycentricInterpolate(Vertex, Vertex, Vertex, float, float, float, Vertex)

Interpolates between three vertices using barycentric weights, writing into 
result
a vertex at an arbitrary point inside (or outside) the triangle they form.
public static void BarycentricInterpolate(in Vertex a, in Vertex b, in Vertex c, float u, float v, float w, out Vertex result)

Parameters

a

Vertex
The first triangle vertex, weighted by 
u
.

b

Vertex
The second triangle vertex, weighted by 
v
.

c

Vertex
The third triangle vertex, weighted by 
w
.

u

float
The barycentric weight of 
a
.

v

float
The barycentric weight of 
b
.

w

float
The barycentric weight of 
c
.

result

Vertex
Receives the interpolated vertex.

Remarks

Use this to place a vertex anywhere within a triangle — for example when re-meshing or clipping a fill. As with Vertex.Lerp, the continuous vertex data is blended and the discrete identifying data is taken from 
a
, so the three vertices must belong to the same fill. The weights are expected to sum to 1 for a point inside the triangle, but are not validated.

BarycentricInterpolate(Vertex, Vertex, Vertex, float, float, float)

Interpolates between three vertices using barycentric weights, returning the vertex at that point. Convenience overload that returns the result instead of writing to an out parameter.
public static Vertex BarycentricInterpolate(in Vertex a, in Vertex b, in Vertex c, float u, float v, float w)

Parameters

a

Vertex
The first triangle vertex, weighted by 
u
.

b

Vertex
The second triangle vertex, weighted by 
v
.

c

Vertex
The third triangle vertex, weighted by 
w
.

u

float
The barycentric weight of 
a
.

v

float
The barycentric weight of 
b
.

w

float
The barycentric weight of 
c
.
