Struct epaint::mesh::Mesh

source ·
pub struct Mesh {
    pub indices: Vec<u32>,
    pub vertices: Vec<Vertex>,
    pub texture_id: TextureId,
}
Expand description

Textured triangles in two dimensions.

Fields§

§indices: Vec<u32>

Draw as triangles (i.e. the length is always multiple of three).

If you only support 16-bit indices you can use Mesh::split_to_u16.

egui is NOT consistent with what winding order it uses, so turn off backface culling.

§vertices: Vec<Vertex>

The vertex data indexed by indices.

§texture_id: TextureId

The texture to use when drawing these triangles.

Implementations§

source§

impl Mesh

source

pub fn with_texture(texture_id: TextureId) -> Self

source

pub fn clear(&mut self)

Restore to default state, but without freeing memory.

source

pub fn bytes_used(&self) -> usize

source

pub fn is_valid(&self) -> bool

Are all indices within the bounds of the contained vertices?

source

pub fn is_empty(&self) -> bool

source

pub fn calc_bounds(&self) -> Rect

Calculate a bounding rectangle.

source

pub fn append(&mut self, other: Self)

Append all the indices and vertices of other to self.

source

pub fn append_ref(&mut self, other: &Self)

Append all the indices and vertices of other to self without taking ownership.

source

pub fn colored_vertex(&mut self, pos: Pos2, color: Color32)

source

pub fn add_triangle(&mut self, a: u32, b: u32, c: u32)

Add a triangle.

source

pub fn reserve_triangles(&mut self, additional_triangles: usize)

Make room for this many additional triangles (will reserve 3x as many indices). See also reserve_vertices.

source

pub fn reserve_vertices(&mut self, additional: usize)

Make room for this many additional vertices. See also reserve_triangles.

source

pub fn add_rect_with_uv(&mut self, rect: Rect, uv: Rect, color: Color32)

Rectangle with a texture and color.

source

pub fn add_colored_rect(&mut self, rect: Rect, color: Color32)

Uniformly colored rectangle.

source

pub fn split_to_u16(self) -> Vec<Mesh16>

This is for platforms that only support 16-bit index buffers.

Splits this mesh into many smaller meshes (if needed) where the smaller meshes have 16-bit indices.

source

pub fn translate(&mut self, delta: Vec2)

Translate location by this much, in-place

source

pub fn rotate(&mut self, rot: Rot2, origin: Pos2)

Rotate by some angle about an origin, in-place.

Origin is a position in screen space.
