Abstract
Devices and methods for rendering objects using ray tracing are provided which include generating a low resolution version of a high resolution mesh representing objects in the scene, determining points on curved surfaces of curved surface patches defined for one of triangles and bi-linear quadrangles of the low resolution version of the high resolution mesh, performing ray intersection testing by casting rays toward surfaces of the high resolution mesh which are approximated from new points calculated by offset values along interpolated normals from the points on the curved surfaces of the curved surface patches and rendering the objects in the scene based on the ray intersection testing.
