Polynomial Fisheye model and space conversion

Hi guys,

We want to extract 3d world position coordinate
And convert to its final 2d image space coordinate.

Unfortunately we not sure which model is used for the fish eye camera and what are the needed steps to get the conversion right.

Question in stack exchange:

Thank you,
Keep up the great work

Hi guys “thank you” for your answer,
as it seem from this link
the the function that might help is :

`ccl_device float2 direction_to_fisheye_lens_polynomial(float3 dir, float coeff0, float4 coeffs,`

`                                                       float width, float height)`
