Struct frenderer::meshes::FlatRenderer

pub struct FlatRenderer { /* private fields */ }

Renders groups of 3D meshes with flat colors and no lighting.

Implementations

impl FlatRenderer

pub fn new( gpu: &WGPU, color_target: ColorTargetState, depth_format: TextureFormat ) -> Self

Creates a new FlatRenderer meant to draw into the given color target state with the given depth texture format.

pub fn set_camera(&mut self, gpu: &WGPU, camera: Camera3D)

Sets the given camera for all mesh groups.

pub fn add_mesh_group( &mut self, gpu: &WGPU, material_colors: &[[f32; 4]], vertices: Vec<FlatVertex>, indices: Vec<u32>, mesh_info: Vec<MeshEntry> ) -> MeshGroup

Add a mesh group with the given array of material colors. All meshes in the group pull from the same vertex buffer, and each submesh is defined in terms of a range of indices within that buffer. When loading your mesh resources from whatever format they’re stored in, fill out vertex and index vecs while tracking the beginning and end of each mesh and submesh (see MeshEntry for details).

pub fn resize_group_mesh( &mut self, gpu: &WGPU, which: MeshGroup, mesh_idx: usize, len: usize ) -> usize

Change the number of instances of the given mesh of the given mesh group.

pub fn mesh_group_count(&self) -> usize

Returns how many mesh groups there are.

pub fn mesh_count(&self, which: MeshGroup) -> usize

Returns how many meshes there are in the given mesh group.

pub fn mesh_instance_count(&self, which: MeshGroup, mesh_number: usize) -> usize

Returns how many mesh instances there are in the given mesh of the given mesh group.

pub fn get_meshes(&self, which: MeshGroup, mesh_number: usize) -> &[Transform3D]

Gets the transforms of every instance of the given mesh of a mesh group.

pub fn get_meshes_mut( &mut self, which: MeshGroup, mesh_number: usize ) -> &mut [Transform3D]

Gets the (mutable) transforms of every instance of the given mesh of a mesh group.

pub fn remove_mesh_group(&mut self, which: MeshGroup)

Deletes a mesh group, leaving its slot free to be reused.

pub fn upload_meshes( &mut self, gpu: &WGPU, which: MeshGroup, mesh_number: usize, range: impl RangeBounds<usize> )

Uploads a range of instance data for the given mesh of a given mesh group.

pub fn upload_meshes_group(&mut self, gpu: &WGPU, which: MeshGroup)

Uploads instance data for all the meshes of a given mesh group.

pub fn render<'s, 'pass>( &'s self, rpass: &mut RenderPass<'pass>, which: impl RangeBounds<usize> )

where 's: 'pass,

Renders the given range of mesh groups into the given wgpu::RenderPass.
