The FromCorners method is a static method of the Frustum struct in the Sandbox namespace. It constructs a Frustum object using four corner rays and two distance values representing the near and far planes. This method is useful for creating a frustum from specific corner rays, which can be used in various 3D rendering and collision detection scenarios.
To use the FromCorners method, you need to provide four corner rays and two float values representing the near and far distances. The corner rays should be passed by reference, and the near and far values should be positive floats indicating the distances from the origin to the respective planes.
Example usage:
Ray topLeftRay = new Ray(origin, direction);
Ray topRightRay = new Ray(origin, direction);
Ray bottomRightRay = new Ray(origin, direction);
Ray bottomLeftRay = new Ray(origin, direction);
float nearDistance = 0.1f;
float farDistance = 1000f;
Frustum frustum = Frustum.FromCorners(ref topLeftRay, ref topRightRay, ref bottomRightRay, ref bottomLeftRay, nearDistance, farDistance);
Ray topLeftRay = new Ray(new Vector3(0, 0, 0), new Vector3(1, 0, 0)); Ray topRightRay = new Ray(new Vector3(0, 0, 0), new Vector3(0, 1, 0)); Ray bottomRightRay = new Ray(new Vector3(0, 0, 0), new Vector3(0, 0, 1)); Ray bottomLeftRay = new Ray(new Vector3(0, 0, 0), new Vector3(1, 1, 0)); float nearDistance = 0.1f; float farDistance = 1000f; Frustum frustum = Frustum.FromCorners(ref topLeftRay, ref topRightRay, ref bottomRightRay, ref bottomLeftRay, nearDistance, farDistance);
