When running with the embree 2.16 a KeyNotFoundException occurs at the following line:
https://github.com/TomCrypto/Embree.NET/blob/master/Library/Embree.cs#L653
If the sample is run with a serial foreach loop the exception does not occur but the rendered image is black:
https://github.com/TomCrypto/Embree.NET/blob/master/Sample/Program.cs#L203
Using 4 RayPacket1 calls instead works as expected
The following files appear to be missing in the download zip:
embree.dll, tbb.dll, tbbmalloc.dll
It should be (Something like):
public static Matrix Invert(Matrix mat)
{
// Work out determinant of the 3x3 submatrix.
var det = mat.U.X * (mat.V.Y * mat.W.Z - mat.W.Y * mat.V.Z)
- mat.V.X * (mat.W.Z * mat.U.Y - mat.W.Y * mat.U.Z)
+ mat.W.X * (mat.U.Y * mat.V.Z - mat.V.Y * mat.U.Z);
if (Math.Abs(det) < 0)
throw new ArgumentException("Matrix is not invertible");
float ux = mat.V.Y * mat.W.Z - mat.V.Z * mat.W.Y;
float uy = mat.W.Y * mat.U.Z - mat.U.Y * mat.W.Z;
float uz = mat.U.Y * mat.V.Z - mat.U.Z * mat.V.Y;
float vx = mat.W.X * mat.V.Z - mat.V.X * mat.W.Z;
float vy = mat.U.X * mat.W.Z - mat.W.X * mat.U.Z;
float vz = mat.V.X * mat.U.Z - mat.U.X * mat.V.Z;
float wx = mat.V.X * mat.W.Y - mat.W.X * mat.V.Y;
float wy = mat.W.X * mat.U.Y - mat.U.X * mat.W.Y;
float wz = mat.U.X * mat.V.Y - mat.V.X * mat.U.Y;
Vector inv_u = new Vector(ux, uy, uz);
Vector inv_v = new Vector(vx, vy, vz);
Vector inv_w = new Vector(wx, wy, wz);
// Transform the translation column by this inverse matrix.
var inv_t = -(mat.T.X * inv_u + mat.T.Y * inv_v + mat.T.Z * inv_w);
return new Matrix(inv_u, inv_v, inv_w, inv_t);
}
Hi, this project is a great help for c# developers. I would like to use Embree in a c# project. However I am having some problems using the sample code.
[+] 64-bit mode.
[+] Building a test scene.
[!] Error: An invalid operation was attempted on an Embree object.

Could you help me to figure this out? Thank you.
