Struct RayMarchRenderer 

pub struct RayMarchRenderer {
    pub width: usize,
    pub height: usize,
    pub fov: f64,
    pub camera_pos: [f64; 3],
    pub camera_target: [f64; 3],
}

A simple camera/renderer that generates rays and produces image buffers via ray marching.

Fields

width: usize

Image width in pixels.

height: usize

Image height in pixels.

fov: f64

Vertical field of view in radians.

camera_pos: [f64; 3]

Camera position in world space.

camera_target: [f64; 3]

Point the camera looks at.

Implementations

impl RayMarchRenderer

pub fn new( width: usize, height: usize, fov: f64, camera_pos: [f64; 3], camera_target: [f64; 3], ) -> Self

Construct a new renderer.

pub fn generate_ray(&self, px: usize, py: usize) -> Ray

Generate the primary ray for pixel (px, py).

Pixel coordinates are measured from the top-left corner.

pub fn render_depth(&self, sdf: &dyn Sdf) -> Vec<f64>

Render the scene as a depth buffer.

Returns a flat width × height Vecf64where each element is thetvalue at the nearest surface hit, orf64::INFINITY` on a miss.

pub fn render_normals(&self, sdf: &dyn Sdf) -> Vec<[f64; 3]>

Render the scene as a normal buffer.

Returns a flat width × height Vec<\[f64; 3\]> where each element is the surface normal at the hit point, or \[0,0,0\] on a miss.

Trait Implementations

impl Clone for RayMarchRenderer

fn clone(&self) -> RayMarchRenderer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RayMarchRenderer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
