Claim Text:
1. A computer-enabled method of shading a scene using a point in a point cloud, the point representing a sample location on a surface primitive of an object in the scene, the surface primitive lying at least partially within a camera viewing frustum of a virtual camera, the virtual camera having a focal point, the method comprising: determining a sample location distance, wherein the sample location distance is a near plane distance of the camera viewing frustum or the length of a line between the sample location on the surface primitive and the focal point of the virtual camera; obtaining a solid angle of the surface primitive subtended at the focal point of the virtual camera; determining a first desired point area of the point in the point cloud based on the sample location distance and the solid angle; and shading the scene using the first desired point area of the point in the point cloud.
