Struct Mesh 

pub struct Mesh { /* private fields */ }

2D polygon mesh.

All of its creation methods are just shortcuts for doing the same operation via a MeshBuilder.

Implementations

impl Mesh

pub fn new_line<P>( ctx: &mut Context, quad_ctx: &mut GraphicsContext, points: &[P], width: f32, color: Color, ) -> GameResult<Mesh>

where P: Into<Point2<f32>> + Clone,

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

pub fn new_circle<P>( ctx: &mut Context, quad_ctx: &mut GraphicsContext, mode: DrawMode, point: P, radius: f32, tolerance: f32, color: Color, ) -> GameResult<Mesh>

where P: Into<Point2<f32>>,

Create a new mesh for a circle.

pub fn new_ellipse<P>( ctx: &mut Context, quad_ctx: &mut GraphicsContext, mode: DrawMode, point: P, radius1: f32, radius2: f32, tolerance: f32, color: Color, ) -> GameResult<Mesh>

where P: Into<Point2<f32>>,

Create a new mesh for an ellipse.

pub fn new_polyline<P>( ctx: &mut Context, quad_ctx: &mut GraphicsContext, mode: DrawMode, points: &[P], color: Color, ) -> GameResult<Mesh>

where P: Into<Point2<f32>> + Clone,

Create a new mesh for series of connected lines.

pub fn new_polygon<P>( ctx: &mut Context, quad_ctx: &mut GraphicsContext, mode: DrawMode, points: &[P], color: Color, ) -> GameResult<Mesh>

where P: Into<Point2<f32>> + Clone,

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( ctx: &mut Context, quad_ctx: &mut GraphicsContext, mode: DrawMode, bounds: Rect, color: Color, ) -> GameResult<Mesh>

Create a new mesh for a rectangle

pub fn new_rounded_rectangle( ctx: &mut Context, quad_ctx: &mut GraphicsContext, mode: DrawMode, bounds: Rect, radius: f32, color: Color, ) -> GameResult<Mesh>

Create a new mesh for a rounded rectangle

pub fn from_triangles<P>( ctx: &mut Context, quad_ctx: &mut GraphicsContext, triangles: &[P], color: Color, ) -> GameResult<Mesh>

where P: Into<Point2<f32>> + Clone,

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

pub fn from_raw<V>( ctx: &mut Context, quad_ctx: &mut GraphicsContext, verts: &[V], indices: &[u16], image: Option<Image>, ) -> GameResult<Mesh>

where V: Into<Vertex> + Clone,

Creates a Mesh from a raw list of triangles defined from points and indices, with the given UV texture coordinates. You may also supply an Image to use as a texture, if you pass None, it will just use a pure white texture.

This is the most primitive mesh-creation method, but allows you full control over the tesselation and texturing. As such it will panic or produce incorrect/invalid output (that may later cause drawing to panic), if:

• indices contains a value out of bounds of verts
• verts is longer than u16::MAX elements.

Trait Implementations

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, ctx: &mut Context, quad_ctx: &mut GraphicsContext, param: DrawParam, ) -> GameResult

Draws the drawable onto the rendering target.

fn set_blend_mode(&mut self, mode: Option<BlendMode>)

Sets the blend mode to be used when drawing this drawable. This overrides the general graphics::set_blend_mode(). If None is set, defers to the blend mode set by graphics::set_blend_mode().

fn blend_mode(&self) -> Option<BlendMode>

Gets the blend mode to be used when drawing this drawable.

fn dimensions(&self, _ctx: &mut Context) -> Option<Rect>

impl Drop for Mesh

fn drop(&mut self)

Executes the destructor for this type.
