Struct SliceMeshRenderData 

pub struct SliceMeshRenderData { /* private fields */ }

GPU resources for rendering a slice mesh (volume cross-section cap).

Uses the same shader as surface meshes but with simplified geometry.

Implementations

impl SliceMeshRenderData

pub fn new( device: &Device, bind_group_layout: &BindGroupLayout, camera_buffer: &Buffer, vertices: &[Vec3], normals: &[Vec3], colors: &[Vec4], ) -> Self

Creates new render data from slice mesh geometry.

Arguments

• device - The wgpu device
• bind_group_layout - The bind group layout for surface meshes
• camera_buffer - The camera uniform buffer
• vertices - Vertex positions (3 per triangle)
• normals - Vertex normals (3 per triangle)
• colors - Vertex colors (3 per triangle)

pub fn update( &mut self, device: &Device, queue: &Queue, bind_group_layout: &BindGroupLayout, camera_buffer: &Buffer, vertices: &[Vec3], normals: &[Vec3], colors: &[Vec4], )

Updates the slice mesh geometry.

This recreates the buffers if the geometry size has changed.

pub fn update_uniforms(&self, queue: &Queue, color: Vec3)

Updates the uniform buffer with new settings.

pub fn bind_group(&self) -> &BindGroup

Returns the bind group for rendering.

pub fn index_buffer(&self) -> &Buffer

Returns the index buffer for rendering.

pub fn num_indices(&self) -> u32

Returns the number of indices to draw.

pub fn is_empty(&self) -> bool

Returns true if the slice mesh is empty.
