Struct three_d::core::buffer::VertexBuffer

pub struct VertexBuffer { /* private fields */ }

A buffer containing per vertex data, for example positions, normals, uv coordinates or colors. To send this data to a shader, use the Program::use_vertex_attribute method.

Implementations

impl VertexBuffer

pub fn new(context: &Context) -> Self

Creates a new empty vertex buffer.

pub fn new_with_data<T: BufferDataType>(context: &Context, data: &[T]) -> Self

Creates a new vertex buffer and fills it with the given data. The data should be in the same format as specified in the shader. As an example, if specified as vec3 in the shader it needs to be specified as an array of Vector3<T> where T is a primitive type that implements BufferDataType, for example can be f16 or f32.

pub fn fill<T: BufferDataType>(&mut self, data: &[T])

Fills the vertex buffer with the given data. The data should be in the same format as specified in the shader. As an example, if specified as vec3 in the shader it needs to be specified as an array of Vector3<T> where T is a primitive type that implements BufferDataType, for example can be f16 or f32.

pub fn count(&self) -> u32

The number of values in the buffer.

pub fn vertex_count(&self) -> u32

The number of vertex attributes in the buffer.
