The GPU pair evaluator reported false-positive overlaps for all candidates because the bitmap coordinate system didn't account for Part.CreateAtOrigin's Location offset. When rotation produced negative coordinates, CreateAtOrigin sets Location = -bbox.Location (non-zero), but the offset formula assumed Location was always (0,0). Two fixes: - Rasterize bitmaps from Part.CreateAtOrigin directly (new FromPart method) instead of separately rotating polygons and computing bbox, eliminating any Polygon.Rotate vs Program.Rotate mismatch - Correct offset formula to include the Location shift: (Part2Offset - partB.Location) instead of raw Part2Offset Also optimized post-kernel bounding computation: pre-compute vertices once per rotation group and process results with Parallel.For, matching the CPU evaluator's concurrency.
