Struct Mesh

pub struct Mesh { /* private fields */ }

Mesh data stored on the GPU as a vertex and index buffer. Cheap to clone.

Implementations

impl Mesh

pub fn from_data(gfx: &impl Has<GraphicsContext>, raw: MeshData<'_>) -> Self

Create a new mesh from MeshData.

pub fn new_line( gfx: &impl Has<GraphicsContext>, points: &[impl Into<Point2<f32>> + Clone], width: f32, color: Color, ) -> GameResult<Self>

Create a new mesh for a line of one or more connected segments.

pub fn new_circle( gfx: &impl Has<GraphicsContext>, mode: DrawMode, point: impl Into<Point2<f32>>, radius: f32, tolerance: f32, color: Color, ) -> GameResult<Self>

Create a new mesh for a circle.

pub fn new_ellipse( gfx: &impl Has<GraphicsContext>, mode: DrawMode, point: impl Into<Point2<f32>>, radius1: f32, radius2: f32, tolerance: f32, color: Color, ) -> GameResult<Self>

Create a new mesh for an ellipse.

pub fn new_polyline( gfx: &impl Has<GraphicsContext>, mode: DrawMode, points: &[impl Into<Point2<f32>> + Clone], color: Color, ) -> GameResult<Self>

Create a new mesh for a series of connected lines.

pub fn new_polygon( gfx: &impl Has<GraphicsContext>, mode: DrawMode, points: &[impl Into<Point2<f32>> + Clone], color: Color, ) -> GameResult<Self>

Create a new mesh for closed polygon. The points given must be in clockwise order, otherwise at best the polygon will not draw.

pub fn new_rectangle( gfx: &impl Has<GraphicsContext>, mode: DrawMode, bounds: Rect, color: Color, ) -> GameResult<Self>

Create a new mesh for a rectangle.

pub fn new_rounded_rectangle( gfx: &impl Has<GraphicsContext>, mode: DrawMode, bounds: Rect, radius: f32, color: Color, ) -> GameResult<Self>

Create a new mesh for a rounded rectangle.

pub fn from_triangles( gfx: &impl Has<GraphicsContext>, triangles: &[impl Into<Point2<f32>> + Clone], color: Color, ) -> GameResult<Self>

Create a new Mesh from a raw list of triangle points.

pub fn wgpu(&self) -> (&Buffer, &Buffer)

Returns the WGPU vertex and index buffers of this mesh, in that order.

pub fn vertex_count(&self) -> usize

Returns the number of vertices in this mesh.

pub fn index_count(&self) -> usize

Returns the number of indices in this mesh.

Trait Implementations

impl Clone for Mesh

fn clone(&self) -> Mesh

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

Performs copy-assignment from source.

impl Debug for Mesh

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

Formats the value using the given formatter.

impl Drawable for Mesh

fn draw(&self, canvas: &mut Canvas, param: impl Into<DrawParam>)

Draws the drawable onto the canvas.

fn dimensions(&self, _gfx: &impl Has<GraphicsContext>) -> Option<Rect>

Returns a bounding box in the form of a Rect.
