Struct Mesh3D 

pub struct Mesh3D { /* private fields */ }

A triangle mesh with solid (per-vertex or uniform) vertex colours.

Port of silx plot3d.items.Mesh (a DataItem3D wrapping a scene.primitives.Mesh3D). Vertices carry positions, colours and optional normals; when no normals are supplied the geometric flat face normal is used per triangle (via flat_normal), so the headlight still shades the surface. Strips and fans are expanded to a triangle list on the CPU since the GPU path is TriangleList only.

Implementations

impl Mesh3D

pub fn new() -> Self

An empty mesh (white, Triangles mode).

pub fn set_data( &mut self, positions: &[[f32; 3]], colors: MeshColor, normals: Option<&[[f32; 3]]>, mode: MeshDrawMode, indices: Option<&[u32]>, ) -> bool

Set the mesh geometry (silx Mesh.setData). Returns false (leaving the mesh unchanged) when the attributes are inconsistent: per-vertex colours or normals not matching the vertex count, or an out-of-range index. An empty positions clears the mesh and returns true (silx treats it as no mesh).

pub fn with_data( self, positions: &[[f32; 3]], colors: MeshColor, normals: Option<&[[f32; 3]]>, mode: MeshDrawMode, indices: Option<&[u32]>, ) -> Self

Builder form of set_data; inconsistent attributes leave the mesh empty.

pub fn mode(&self) -> MeshDrawMode

The drawing mode.

pub fn len(&self) -> usize

Number of vertices.

pub fn is_empty(&self) -> bool

True when there are no vertices.

pub fn bounds(&self) -> Option<(Vec3, Vec3)>

Axis-aligned data bounds (min, max), or None when empty.

pub fn append_to(&self, geometry: &mut Scene3dGeometry)

Append this mesh’s triangles to geometry for upload via crate::render::gpu_scene3d::set_scene3d.
