The title of the invention is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed.

Claim Rejections - 35 USC § 101
35 U.S.C. 101 reads as follows:
Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
Claims 1-14 are rejected under 35 U.S.C. 101 because the claimed invention is directed to non-statutory subject matter.
The claim(s) does/do not fall within at least one of the four categories of patent eligible subject matter because claim 1 is directed to a machine-implemented method of graphics processing, comprising the steps of tracing, updating and using which are nothing more than software instructions. Software instructions are non-statutory under 35 U.S.C. 101.
Claims 2-14 depend from claim 1 and comprise additional steps, for example claim 2 comprises the steps of transforming and combining, therefore claims 2-14 have the same problem as claim 1 and are rejected under the same rationale.
Double Patenting
The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.

The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used.

Claims 1-12 and 15-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-3, 5-16 and 18-20 of U.S. Patent No. 10,672,183 B2. Although the claims at issue are not identical, they are not patentably distinct from each other because the instant claims are a broader version of the patent claims.
Claims 1-9, 12-13, 15-17 and 20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-8, 11-15 and 20 of U.S. Patent No. 10,008,032 B2 in view of UNGER et. al., "Spatially varying image based lighting by light probe sequences: Capture, processing and rendering." The Visual Computer 23.7 (2007): 453-465 (from IDS of 1/15/25).
Regarding claims 1, 15 and 20 the patent teaches using the updated directional representation of lighting for the probe position for determine lighting indications but doesn’t teach, however the analogous prior art UNGER teaches the light probes are used for rendering (UNGER: abstract see col. 1 line 19-col. 2 line 15).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the light probes are used for rendering as shown in UNGER with the patent for the benefit of fulfilling a need in the prior art for equipment and methods for sampling of spatially and temporally varying lighting situations with detailed measurements of lighting that can be used to achieve a higher level of realism in rendered images, in order to address a shortcoming in the prior art in that existing methods of image based lighting techniques are still based on images of static lighting at a single point in space, whereas most real world lighting conditions vary over both time and space [pg. 1, right col., 2nd par. line 1 – pg. 2, left col. line 3].
