The Trace method in the BBox struct is used to determine if a ray intersects with the bounding box. It calculates the intersection point and returns whether the intersection occurs within a specified distance.
The Trace method in the BBox struct is used to determine if a ray intersects with the bounding box. It calculates the intersection point and returns whether the intersection occurs within a specified distance.
To use the Trace method, you need to provide a Ray object, a maximum distance for the trace, and an output parameter to store the distance to the intersection point if an intersection occurs.
The method returns a boolean value indicating whether the ray intersects the bounding box within the specified distance.
// Example usage of BBox.Trace method
BBox boundingBox = new BBox(new Vector3(0, 0, 0), new Vector3(1, 1, 1));
Ray ray = new Ray(new Vector3(-1, 0.5f, 0.5f), new Vector3(1, 0, 0));
float maxDistance = 10.0f;
float hitDistance;
bool intersects = boundingBox.Trace(ray, maxDistance, out hitDistance);
if (intersects)
{
// The ray intersects the bounding box
Console.WriteLine($"Intersection at distance: {hitDistance}");
}
else
{
// No intersection within the specified distance
Console.WriteLine("No intersection detected.");
}
