houdini vex loop over points

To loop over points in Houdini VEX, you can use a for loop combined with the npoints() function to iterate through each point in a geometry. Here's an example of how you can do this:

int numPoints = npoints(geoself());
for (int i = 0; i < numPoints; i++)
{
    vector pointPosition = point(geoself(), "P", i);

    // Your code here...
    // Perform operations on each point

    // Example: Print the position of each point
    printf("Point %d position: %g %g %g\n", i, pointPosition.x, pointPosition.y, pointPosition.z);
}

In this example, we first obtain the total number of points in the current geometry using npoints(geoself()). We then use a for loop to iterate from 0 to numPoints - 1, accessing each point's position using the point() function.

You can perform any desired operations on each point within the loop. In the provided example, we simply print the position of each point using printf().

Remember to replace the placeholder code with your specific operations for each point.
