Question about fisheye implementation #21

Closed yudai-kato-aisin closed 3 months ago

yudai-kato-aisin commented 3 months ago

I would like to ask a question about fisheye branch. I'm very interested in the fisheye projection for 3DGS.

Can I ask what fisheye model do you use? I have checked the Jacobian, but could not estimate the model due to lack of mathmatical knowledge. https://github.com/limacv/GaussianSplattingViewer/blob/647c0d415dcb58c636c237241fa7bf2a1b358e54/shaders/gau_vert.glsl#L107-L111

It's very helpful if you could answer my question. Thank you in advance.

I'm using equidistant projection as in https://wiki.panotools.org/Fisheye_Projection
