An exploration of acceleration modules in Instant-angelo

[xsl316]

Dear Dr. Chongjie,
I am a master at Chongqing Jiaotong University, and my research direction is Novel View Synthesis and 3D Reconstruction.
Your Instant-angelo is a great work and I'm very interested in it.
Here, I would like to ask some questions about the methodology. Could you explain more about, what modules have your implementation added compared to NeuralAngelo? and why is your method so much faster than the original NeuralAngelo?
I can see that your implementation is not based on the framework of NeuralAngelo, so it is difficult for me to compare their differences.
If you could provide some further explanation on this aspect, I would be truly grateful!

Best regards,
Ms. Suling
