Struct VolumeRenderParams 

pub struct VolumeRenderParams {
    pub color_tf: ColorTransferFunction,
    pub opacity_tf: OpacityTransferFunction,
    pub gradient_opacity_tf: Option<OpacityTransferFunction>,
    pub window_level: Option<WindowLevel>,
    pub blend_mode: BlendMode,
    pub interpolation: Interpolation,
    pub shading: Option<ShadingParams>,
    pub step_size_factor: f32,
    pub clip_planes: Vec<ClipPlane>,
    pub cropping_bounds: Option<Aabb>,
    pub background: [f32; 4],
}

All parameters that control how a volume is rendered.

Built using a fluent builder pattern. Start from VolumeRenderParams::builder or use VolumeRenderParams::default.

Fields

color_tf: ColorTransferFunction

Colour transfer function.

opacity_tf: OpacityTransferFunction

Opacity transfer function.

gradient_opacity_tf: Option<OpacityTransferFunction>

Optional gradient opacity modulation.

window_level: Option<WindowLevel>

Window/level mapping (applied before TF lookup).

blend_mode: BlendMode

Compositing algorithm.

interpolation: Interpolation

Texture interpolation quality.

shading: Option<ShadingParams>

Phong shading — only used in BlendMode::Composite and BlendMode::Isosurface.

step_size_factor: f32

Raycasting step size as a fraction of the smallest voxel spacing (default 0.5).

clip_planes: Vec<ClipPlane>

Up to 6 world-space clip planes.

cropping_bounds: Option<Aabb>

Optional axis-aligned cropping box in world coordinates.

background: [f32; 4]

Background colour RGBA in [0, 1].
