The provided code v@N={1,0,0}; appears to be written in Houdini's VEX (Vector Expression Language), which is commonly used in Houdini for shader development, geometry manipulation, and other procedural operations.

What the code does:

1. v@N:

   • This sets the variable N, which in Houdini typically represents the surface normal vector.
   • The v@ prefix specifies that the type of N is a vector (a three-component float value, often representing x, y, and z).

2. ={1,0,0}:

   • This assigns the value {1,0,0} to the N vector.
   • {1,0,0} is a vector pointing in the positive X-direction in 3D space (x=1, y=0, z=0).

Summary:

The code sets the normal vector N to point along the positive X-axis for the geometry's points or primitives (depending on where the code is applied).
