Struct PinholeCamera 

pub struct PinholeCamera {
    pub fx: f32,
    pub fy: f32,
    pub cx: f32,
    pub cy: f32,
    pub width: u32,
    pub height: u32,
}

Pinhole camera intrinsics.

Fields

fx: f32

Focal length in x (pixels).

fy: f32

Focal length in y (pixels).

cx: f32

Principal point x (pixels).

cy: f32

Principal point y (pixels).

width: u32

Image width in pixels.

height: u32

Image height in pixels.

Implementations

impl PinholeCamera

pub fn new( fx: f32, fy: f32, cx: f32, cy: f32, w: u32, h: u32, ) -> NerfResult<Self>

Create a new pinhole camera model.

Errors

Returns InvalidCameraIntrinsics for non-positive focal lengths or zero dimensions.

pub fn ray_through_pixel( &self, u: f32, v: f32, c2w: &[f32; 12], ) -> NerfResult<Ray>

Generate the ray through pixel (u, v) in camera coordinates.

c2w is a row-major 3×4 camera-to-world transform:

[ R[0,0] R[0,1] R[0,2] t[0]
  R[1,0] R[1,1] R[1,2] t[1]
  R[2,0] R[2,1] R[2,2] t[2] ]

Errors

Returns ZeroRayDirection if the transformed direction is near-zero.

pub fn generate_rays(&self, c2w: &[f32; 12]) -> NerfResult<Vec<Ray>>

Generate all W×H rays for the camera with given c2w matrix.

Output: width * height rays in row-major order (left-to-right, top-to-bottom).

Errors

Returns ZeroRayDirection if any pixel ray has near-zero direction.
