Techniques for performing thread local garbage collection are described herein. Techniques include automatic profiling and separation of private and shared objects, allowing for efficient recovery of thread local memory. In some embodiments, a speculative private heap is assigned for a thread within memory. The garbage collection system may assume and operate as such a distribution is private until proven not so unless there is a pre-indication that the distribution site generates a shared object. When reachable outside the thread, the allocation of objects in the private heap may violate the speculative state of the heap. When a violation of the speculative state is detected, an indication may be generated to inform a garbage collection system that may prevent thread local memory reclaim operations until the speculative state is repaired. The garbage collection system may learn from violations to reduce the allocation of invalid private objects and improve the efficiency of the garbage collection system.

This invention discloses a hologram calculation and occlusion processing method based on shared object point sampling. Multiple pixels are selected as sampling center points on the hologram plane to form a sampling grid. For each sampling center point, a cone-shaped beam composed of several rays is emitted to perform object point sampling, filtering out visible object points. For each pixel on the holographic plane, K sampling center points are selected based on its positional relationship with the sampling center points. The union of the visible object point sets is calculated to determine the object point set corresponding to the pixel. Each object point in this set is traversed, and its complex amplitude contribution to the target pixel is calculated. All contributions are accumulated to obtain the light field encoded data of the pixel. The hologram calculation method proposed in this invention can guarantee the coherence between pixels, restore the true occlusion relationship of the model, and reduce the number of samples.
