Implementations

impl GlGeometryBuffer

pub fn new( server: &GlGraphicsServer, desc: GeometryBufferDescriptor<'_>, ) -> Result<GlGeometryBuffer, FrameworkError>

pub fn mode(&self) -> u32

Trait Implementations

impl Drop for GlGeometryBuffer

fn drop(&mut self)

Executes the destructor for this type.

impl GeometryBuffer for GlGeometryBuffer

fn set_buffer_data(&self, buffer: usize, data: &[u8])

Write untyped data to a vertex buffer with the given index.

fn element_count(&self) -> usize

Returns total number of elements in the geometry buffer.

fn set_triangles(&self, triangles: &[TriangleDefinition])

Writes triangles to the buffer. Each triangle definition contains triangle indices, that forms the triangle.

fn set_lines(&self, lines: &[[u32; 2]])

Writes lines to the buffer. Each pair defines starting and ending vertex index of the line.

fn set_points(&self, points: &[u32])

Writes points to the buffer. Each index in the slice defines vertex index.
