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. Can send between 1 and 4 values of InstanceBufferDataType to a shader program for each vertex. Bind this using the Program::use_attribute, Program::use_attribute_vec2, etc. functionality.

Implementations

impl VertexBuffer

pub fn new(context: &Context) -> ThreeDResult<VertexBuffer>

Creates a new empty vertex buffer.

pub fn new_with_static<T: VertexBufferDataType>(
    context: &Context,
    data: &[T]
) -> ThreeDResult<VertexBuffer>

Creates a new vertex buffer and fills it with the given data which must contain between 1 and 4 contiguous values for each vertex. Use this method instead of new_with_dynamic when you do not expect the data to change often.

pub fn fill_with_static<T: VertexBufferDataType>(&mut self, data: &[T])

Fills the vertex buffer with the given data which must contain between 1 and 4 contiguous values for each vertex. Use this method instead of fill_with_dynamic when you do not expect the data to change often.

pub fn new_with_dynamic<T: VertexBufferDataType>(
    context: &Context,
    data: &[T]
) -> ThreeDResult<VertexBuffer>

Creates a new vertex buffer and fills it with the given data which must contain between 1 and 4 contiguous values for each vertex. Use this method instead of new_with_static when you expect the data to change often.

pub fn fill_with_dynamic<T: VertexBufferDataType>(&mut self, data: &[T])

Fills the vertex buffer with the given data which must contain between 1 and 4 contiguous values for each vertex. Use this method instead of fill_with_static when you expect the data to change often.

pub fn count(&self) -> usize

The number of elements in the buffer.

Trait Implementations

impl Drop for VertexBuffer

fn drop(&mut self)

Executes the destructor for this type.
