pub struct Mesh { /* private fields */ }
Expand description
A 3D object made out of vertices representing triangles, lines, or points, with “attribute” values for each vertex.
Meshes can be automatically generated by a bevy AssetLoader
(generally by loading a Gltf
file),
or by converting a primitive shape
using into
.
It is also possible to create one manually.
They can be edited after creation.
Meshes can be rendered with a Material
, like StandardMaterial
in PbrBundle
or ColorMaterial
in ColorMesh2dBundle
.
A Mesh
in Bevy is equivalent to a “primitive” in the glTF format, for a
glTF Mesh representation, see GltfMesh
.
Manual creation
The following function will construct a flat mesh, to be rendered with a
StandardMaterial
or ColorMaterial
:
fn create_simple_parallelogram() -> Mesh {
// Create a new mesh using a triangle list topology, where each set of 3 vertices composes a triangle.
Mesh::new(PrimitiveTopology::TriangleList)
// Add 4 vertices, each with its own position attribute (coordinate in
// 3D space), for each of the corners of the parallelogram.
.with_inserted_attribute(
Mesh::ATTRIBUTE_POSITION,
vec![[0.0, 0.0, 0.0], [1.0, 2.0, 0.0], [2.0, 2.0, 0.0], [1.0, 0.0, 0.0]]
)
// Assign a UV coordinate to each vertex.
.with_inserted_attribute(
Mesh::ATTRIBUTE_UV_0,
vec![[0.0, 1.0], [0.5, 0.0], [1.0, 0.0], [0.5, 1.0]]
)
// Assign normals (everything points outwards)
.with_inserted_attribute(
Mesh::ATTRIBUTE_NORMAL,
vec![[0.0, 0.0, 1.0], [0.0, 0.0, 1.0], [0.0, 0.0, 1.0], [0.0, 0.0, 1.0]]
)
// After defining all the vertices and their attributes, build each triangle using the
// indices of the vertices that make it up in a counter-clockwise order.
.with_indices(Some(Indices::U32(vec![
// First triangle
0, 3, 1,
// Second triangle
1, 3, 2
])))
}
You can see how it looks like here,
used in a PbrBundle
with a square bevy logo texture, with added axis, points,
lines and text for clarity.
Other examples
For further visualization, explanation, and examples, see the built-in Bevy examples, and the implementation of the built-in shapes. In particular, generate_custom_mesh teaches you to access modify a Mesh’s attributes after creating it.
Common points of confusion
- UV maps in Bevy start at the top-left, see
ATTRIBUTE_UV_0
, other APIs can have other conventions,OpenGL
starts at bottom-left. - It is possible and sometimes useful for multiple vertices to have the same position attribute value, it’s a common technique in 3D modelling for complex UV mapping or other calculations.
Use with StandardMaterial
To render correctly with StandardMaterial
, a mesh needs to have properly defined:
UVs
: Bevy needs to know how to map a texture onto the mesh (also true forColorMaterial
).Normals
: Bevy needs to know how light interacts with your mesh. [0.0, 0.0, 1.0] is very common for simple flat meshes on the XY plane, because simple meshes are smooth and they don’t require complex light calculations.- Vertex winding order: by default,
StandardMaterial.cull_mode
isSome(Face::Back)
, which means that Bevy would only render the “front” of each triangle, which is the side of the triangle from where the vertices appear in a counter-clockwise order.
Implementations§
§impl Mesh
impl Mesh
pub const ATTRIBUTE_POSITION: MeshVertexAttribute = _
pub const ATTRIBUTE_POSITION: MeshVertexAttribute = _
Where the vertex is located in space. Use in conjunction with Mesh::insert_attribute
or Mesh::with_inserted_attribute
.
pub const ATTRIBUTE_NORMAL: MeshVertexAttribute = _
pub const ATTRIBUTE_NORMAL: MeshVertexAttribute = _
The direction the vertex normal is facing in.
Use in conjunction with Mesh::insert_attribute
or Mesh::with_inserted_attribute
.
pub const ATTRIBUTE_UV_0: MeshVertexAttribute = _
pub const ATTRIBUTE_UV_0: MeshVertexAttribute = _
Texture coordinates for the vertex. Use in conjunction with Mesh::insert_attribute
or Mesh::with_inserted_attribute
.
Values are generally between 0. and 1., with StandardMaterial
and ColorMaterial
[0.,0.]
is the top left of the texture, and [1.,1.] the bottom-right.
You usually want to only use values in that range, values outside will be
clamped per pixel not for the vertex, “stretching” the borders of the texture.
This behavior can be useful in some cases, usually when the borders have only
one color, for example a logo, and you want to “extend” those borders.
pub const ATTRIBUTE_UV_1: MeshVertexAttribute = _
pub const ATTRIBUTE_UV_1: MeshVertexAttribute = _
Alternate texture coordinates for the vertex. Use in conjunction with
Mesh::insert_attribute
or Mesh::with_inserted_attribute
.
Typically, these are used for lightmaps, textures that provide precomputed illumination.
pub const ATTRIBUTE_TANGENT: MeshVertexAttribute = _
pub const ATTRIBUTE_TANGENT: MeshVertexAttribute = _
The direction of the vertex tangent. Used for normal mapping.
Usually generated with generate_tangents
or
with_generated_tangents
.
pub const ATTRIBUTE_COLOR: MeshVertexAttribute = _
pub const ATTRIBUTE_COLOR: MeshVertexAttribute = _
Per vertex coloring. Use in conjunction with Mesh::insert_attribute
or Mesh::with_inserted_attribute
.
pub const ATTRIBUTE_JOINT_WEIGHT: MeshVertexAttribute = _
pub const ATTRIBUTE_JOINT_WEIGHT: MeshVertexAttribute = _
Per vertex joint transform matrix weight. Use in conjunction with Mesh::insert_attribute
or Mesh::with_inserted_attribute
.
pub const ATTRIBUTE_JOINT_INDEX: MeshVertexAttribute = _
pub const ATTRIBUTE_JOINT_INDEX: MeshVertexAttribute = _
Per vertex joint transform matrix index. Use in conjunction with Mesh::insert_attribute
or Mesh::with_inserted_attribute
.
pub fn new(primitive_topology: PrimitiveTopology) -> Mesh
