Struct paddle::GpuMesh

pub struct GpuMesh {
    pub vertices: Vec<GpuVertex>,
    pub triangles: Vec<GpuTriangle>,
}

Buffer for GPU primitives ready to be drawn, after tesselation and all CPU-side transformations have finished

Fields

vertices: Vec<GpuVertex>

triangles: Vec<GpuTriangle>

Implementations

impl GpuMesh

pub fn new() -> GpuMesh

Create a new, empty mesh

This allocates, so hold on to meshes rather than creating and destroying them

pub fn clear(&mut self)

Clear the mesh, removing anything that has been drawn to it

pub fn add_positioned_vertices(
    &mut self,
    vertices: impl Iterator<Item = Vector>,
    z: f32,
    trans: Transform,
    tex_trans: Option<Transform>,
    bkg: Background<'_>
) -> u32

Add vertices from an iterator, some transforms, and a background

pub fn set_z(&mut self, z: i16)

Sets the z value for all vertices in the Mesh

pub fn scale(&mut self, r: f32)

Scales all vertices in the mesh by the given factor, taking (0,0) as origin
