Enum glitter::types::DrawingMode

pub enum DrawingMode {
    Points,
    LineStrip,
    LineLoop,
    Lines,
    TriangleStrip,
    TriangleFan,
    Triangles,
}

The primitive drawing modes for drawing raw vertex data.

Variants

Points

Draw each vertex as a single point.

LineStrip

Draw a connected line segment, where each vertex is connected to the next. The first and last vertex are treated as the start and end points.

LineLoop

Draw a self-connected line segment, where each vertex is connected to the next, and the last vertex connects to the first.

Lines

Draw each pair of vertices as individual line segments.

TriangleStrip

Draw the vertices as a strip of triangles. The first three vertices form the first triangle, then the next vertex plus the previous two vertices form the next triangle, and so on. For example, vertices v1, v2, and v3 form the first triangle, then vertices v2, v3, and v4 form the next, and so on.

TriangleFan

Draw the vertices as a triangle fan. The first vertex, v1 is the fan's 'center'. Vertices v2 and v3 form the first triangle with the center, v1. Then vertices v3, v4, and v1 form the next triangle, then vertices v4, v5, and v1, and so on.

Triangles

Draw each group of three vertices as a triangle.

Methods

impl DrawingMode

pub fn from_gl(gl_enum: GLenum) -> Result<Self, ()>

Convert from a raw OpenGL integer value to an enum variant. Returns an error if the value is not a valid enum variant.

pub fn gl_enum(&self) -> GLenum

Return the OpenGL integer value for a given enum variant.

Trait Implementations

impl Debug for DrawingMode

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Clone for DrawingMode

fn clone(&self) -> DrawingMode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for DrawingMode

impl PartialEq for DrawingMode

fn eq(&self, __arg_0: &DrawingMode) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Eq for DrawingMode

impl Hash for DrawingMode

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].
