GPU resources for gridcube visualization.

Fields

position_buffer: Buffer

Combined buffer: first 36 entries are unit cube template vertices (vec4), followed by per-instance data (vec4: xyz=center, w=half_size).

normal_buffer: Buffer

Cube template normals (36 entries, vec4).

scalar_buffer: Buffer

Per-instance scalar values.

uniform_buffer: Buffer

Uniform buffer.

colormap_texture: Texture

Colormap texture (1D, RGBA).

colormap_view: TextureView

Colormap texture view.

colormap_sampler: Sampler

Colormap sampler.

bind_group: BindGroup

Bind group (Group 0).

num_instances: u32

Number of instances (grid nodes/cells).

shadow_bind_group: Option<BindGroup>

Shadow pass bind group.

shadow_model_buffer: Option<Buffer>

Shadow model uniform buffer.

Implementations

impl GridcubeRenderData

pub fn new( device: &Device, queue: &Queue, bind_group_layout: &BindGroupLayout, camera_buffer: &Buffer, centers: &[Vec3], half_size: f32, scalars: &[f32], colormap_colors: &[Vec3], ) -> Self

Creates new gridcube render data.

Arguments

• centers - Per-instance cube center positions
• half_size - Half the cube side length (grid spacing / 2)
• scalars - Per-instance scalar values
• colormap_colors - Color samples for the colormap

pub fn update_uniforms(&self, queue: &Queue, uniforms: &GridcubeUniforms)

Updates the uniform buffer.

pub fn update_colormap(&self, queue: &Queue, colors: &[Vec3])

Updates the colormap texture with new colors.

pub fn total_vertices(&self) -> u32

Returns the total number of vertices to draw (36 per instance).

pub fn init_shadow_resources( &mut self, device: &Device, shadow_bind_group_layout: &BindGroupLayout, light_buffer: &Buffer, )

Initializes shadow rendering resources.

pub fn has_shadow_resources(&self) -> bool

Returns whether shadow resources have been initialized.

pub fn update_shadow_model(&self, queue: &Queue, model_matrix: [[f32; 4]; 4])

Updates the shadow model uniform buffer.
