Empower Dandara for combat and survival against enemies bent on oppression.Īwaken, Dandara, to bring freedom and balance to this directionless world.ĮNTER THE HIDDEN REALMS - The Trials of Fear Edition* adds 3 new areas to explore, a new big boss, new powers and mechanics, new music tracks, a new secret ending, as well as many quality of life updates and more! Discover the mysteries and secrets hidden throughout the world of Salt and its diverse array of characters. Defy gravity as you jump across floors, walls, and ceilings alike. Welcome to a unique 2D metroidvania platformer full of mystical creatures and boundless exploration. But not all is lost, for out of this aether of fear arises a heroine, a ray of hope. The citizens, once free spirits, now stand oppressed and isolated. Notably, on theĬhallenging ScanNet200 dataset, OctFormer outperforms sparse-voxel-based CNNsīy 7.3 in mIoU.The world of Salt hangs on the brink of collapse.

Transformers in terms of both efficiency and effectiveness. State-of-the-art performances on a series of 3D segmentation and detectionīenchmarks, surpassing previous sparse-voxel-based CNNs and point cloud Implemented in 10 lines of code with open-sourced libraries and runs 17 timesįaster than other point cloud attentions when the point number exceeds 200k.īuilt upon the octree attention, OctFormer can be easily scaled up and achieves

And we also introduce dilated octreeĪttention to expand the receptive field further. Observing thatĪttentions are robust to the shapes of local windows, we propose a novel octreeĪttention, which leverages sorted shuffled keys of octrees to partition pointĬlouds into local windows containing a fixed number of points while permitting Varies greatly, impeding the efficient execution on GPU. Several works divide point clouds into non-overlapping windows and constrainĪttentions in each local window.

Overwhelming, computation complexity of attentions. The key challenge inĪpplying transformers to point clouds is reducing the quadratic, thus OctFormer can not only serve as a general and effective backbone forģD point cloud segmentation and object detection but also have linearĬomplexity and is scalable for large-scale point clouds.
