A question about the ndc_derivation.pdf #104

Closed zhshi0816 closed 1 year ago

zhshi0816 commented 1 year ago

I have one question about the additional ndc_derivation.pdf. For my understanding, the ndc transformation matrix in the pdf file is used to transform eye coordinate to ndc coordination and the following derivations are all based on that. But according to your code, the inputs for the ndc_rays function are based on world coordinates. Does this affect? Can you explain it a little bit?
