Struct Mesh2D 

pub struct Mesh2D {
    pub visibility: bool,
    pub handle: MeshHandle,
    pub shader: Option<Shader>,
    pub transform: Transform2D,
    pub draw_mode: DrawMode,
}

High-level mesh with visibility, shader, transform, and draw mode.

Cloning is cheap — the handle shares the same GPU buffers.

Fields

visibility: bool

handle: MeshHandle

shader: Option<Shader>

transform: Transform2D

draw_mode: DrawMode

Implementations

impl Mesh2D

pub fn set_shader(&mut self, shader: Shader)

Attaches a shader to this mesh.

pub fn remove_shader(&mut self)

Detaches the current shader.

pub fn get_draw_mode(&self) -> DrawMode

Returns the current draw mode.

pub fn set_draw_mode(&mut self, draw_mode: DrawMode)

Sets the draw mode.

pub fn index_count(&self) -> u32

Returns the index count.

pub fn vertex_count(&self) -> u32

Returns the vertex count.

pub fn has_indices(&self) -> bool

Returns true if this mesh uses indexed drawing.

pub fn is_empty(&self) -> bool

Returns true when the mesh has no vertices.

pub fn is_visible(&self) -> bool

Returns true when the mesh is both visible and non-empty.

pub fn set_visibility(&mut self, enable: bool)

Shows or hides this mesh.

pub fn toggle_visibility(&mut self)

Toggles visibility.

pub fn update(&mut self)

Recomputes the transformation matrix.

pub fn delete(self)

Deletes the GPU resources for this mesh’s handle.

impl Mesh2D

pub fn log_info(&self)

Prints debug information about this mesh to stdout.

pub fn render(&self, proj: &Matrix4<f32>)

Renders this 2D mesh with an orthographic projection matrix.

Sets uProj, uTfm, uLayer uniforms, binds textures and storage buffers, then issues the draw call.

Trait Implementations

impl Clone for Mesh2D

fn clone(&self) -> Mesh2D

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Mesh2D

fn fmt(&self, f: &mut Formatter<'_>) -> Result
