Struct OpticastSettings 

pub struct OpticastSettings {
    pub xres: u32,
    pub yres: u32,
    pub y_start: u32,
    pub y_end: u32,
    pub hx: f32,
    pub hy: f32,
    pub hz: f32,
    pub anginc: f32,
    pub mip_levels: u32,
    pub mip_scan_dist: i32,
    pub max_scan_dist: i32,
}

Per-frame settings the renderer forwards through its passes. Most fields map onto a classic raycaster control: (hx, hy, hz) are the pinhole projection centre + focal length (the voxlap setcamera dahx/dahy/dahz), mip_* drive the distance-mip ladder, and max_scan_dist bounds the ray.

y_start..y_end is the strip-render iteration bound. Default is the full framebuffer (0..yres). Tile / strip callers set a sub-range to render only that horizontal strip; the projection centre stays in absolute screen coords, only the viewport edges shrink.

Fields

xres: u32

yres: u32

y_start: u32

First y-row this render call covers (inclusive). 0 for full-frame.

y_end: u32

One past the last y-row (exclusive). yres for full-frame.

hx: f32

hy: f32

hz: f32

anginc: f32

mip_levels: u32

mip_scan_dist: i32

max_scan_dist: i32

Implementations

impl OpticastSettings

pub fn for_oracle_framebuffer(width: u32, height: u32) -> Self

Default settings for a width × height framebuffer with the convention (hx, hy, hz) = (w/2, h/2, w/2) and anginc = 1. Renders the full frame (y_start = 0, y_end = height).

pub fn with_y_range(self, y_start: u32, y_end: u32) -> Self

Restrict this settings struct to the [y_start, y_end) horizontal strip. Used by the per-strip parallel dispatch — each strip clones the base settings and clamps the y-range. Caller is responsible for ensuring y_start < y_end <= yres.
