Transformation matrix for rendering

[mazhelearn]

Hi!
Thanks for your great work!
I am trying to use this function in your code to render a view that is the same with a img from dataset.
I am wondering if the parameter "camera_mv_bx4x4" is consistent with the transformation matrix (defined here) of the rendered texture image?

Hi @mazhelearn,

Unfortunately, they're different matrices. The transformation matrix defined here was only used to make it compatible with NGP.

To use the code you mentioned, you need to use this line to obtain the camera matrix.

Let me know if you have any other questions!

i want to render a img that is the same with inputed img using the NeuralRender, but this line only generate a random camera matrix.

And in this function i find the details about geting "camera_mv_bx4x4". I wander what parameters is useful to get the "camera_mv_bx4x4". thank u very much.
Happy new year!!!
