The normal of the intersection plane
Opened this issue · 7 comments
Really nice work.
I have a question about the normal. Is it similar to the concept defined in Eq. 7 of "DN-Splatter: Depth and Normal Priors for Gaussian Splatting and Meshing"?
Looking forward to your reply.
Hi, our definition of normal is different from DN-Splatter. We use the ray-gaussian intersection plane's normal as the Gaussian's normal. DN-Splatter uses the axis of minimal scale.
Could you give me more details about the definition of the ray-gaussian intersection plane? Thank you very much.
Hi, you could refer to our paper and here #38 (comment)
I noticed that you have written
Hi, it is not the inversion. The compound operation is n_i = R^T @ S^-1 @ S^-1 @ R @ r_ray
where r_ray is the ray direction.
Sorry, but I am still a little confused. How is the formula
I think you can refer to the above comment to do the transformation step by step.
