Struct PyParticleRenderer 

pub struct PyParticleRenderer {
    pub positions: Vec<f64>,
    pub radii: Vec<f64>,
    pub colors: Vec<f64>,
    pub billboard: bool,
    pub use_instancing: bool,
    pub colormap: Option<PyColormap>,
}

Renderer for particle systems using billboard or instanced geometry.

Fields

positions: Vec<f64>

Flat array of particle positions: [x0, y0, z0, x1, y1, z1, …].

radii: Vec<f64>

Per-particle radii. If length is 1, all particles share that radius.

colors: Vec<f64>

Per-particle RGBA colors. Flat array: [r0, g0, b0, a0, r1, …].

billboard: bool

Whether to use billboard rendering (always face camera).

use_instancing: bool

Whether to use hardware instancing (more efficient for large counts).

colormap: Option<PyColormap>

Optional colormap applied over a scalar field.
