Hello world, again! – Adventures with David Titarenco

New blog! After over a year of absence, I figured I’d spin this baby back up. In other news, here’s how to calculate v0‘s smooth normal in UE4:

FVector GetSmoothNormal(FVector v0, FVector v1, FVector v2, FVector v3, FVector v4) {
	FVector v12 = FVector();
	FVector v23 = FVector();
	FVector v34 = FVector();
	FVector v41 = FVector();
	FVector normal = FVector();
	v1 = v1 – v0;
	v2 = v2 – v0;
	v3 = v3 – v0;
	v4 = v4 – v0;
	v12 = v1 ^ v2;
	v12.Normalize();
	v23 = v2 ^ v3;
	v23.Normalize();
	v34 = v3 ^ v4;
	v34.Normalize();
	v41 = v4 ^ v1;
	v41.Normalize();
	normal = v12 + v23 + v34 + v41;
	normal.Normalize();
	return normal;
}

FVector GetSmoothNormal(FVector v0, FVector v1, FVector v2, FVector v3, FVector v4) {

FVector v12 = FVector();

FVector v23 = FVector();

FVector v34 = FVector();

FVector v41 = FVector();

FVector normal = FVector();

v1 = v1 – v0;

v2 = v2 – v0;

v3 = v3 – v0;

v4 = v4 – v0;

v12 = v1 ^ v2;

v12.Normalize();

v23 = v2 ^ v3;

v23.Normalize();

v34 = v3 ^ v4;

v34.Normalize();

v41 = v4 ^ v1;

v41.Normalize();

normal = v12 + v23 + v34 + v41;

normal.Normalize();

return normal;

}

And here’s the discrete radiosity equation:
$B_{i}=E_{i}+\rho_{i}\sum\limits _{i=1}^{n}F_{ij}B_{j}$

where $F_{ij}$ is the geometrical view factor for the radiation leaving $j$ and hitting patch $i$ . In truth, this has been a test. I just wanted to make sure that LaTeX and syntax highlighting work. Cheers!
