Struct zaplib::GpuGeometry

pub struct GpuGeometry { /* private fields */ }

A pointer to a [CxGpuGeometry] (indexed in Cx::gpu_geometries using GpuGeometry::gpu_geometry_id),

Cloning a GpuGeometry doesn’t copy the underlying buffer; it just adds a reference count to the existing buffer.

The corresponding GPU buffer ([CxGpuGeometry]) gets marked for reuse when there are no more references to it.

TODO(JP): When creating a big GpuGeometry and then dropping it, we don’t clear out the data until we reuse it (which might be never). We might want to add a cleanup sweep at the end of the draw cycle. Also, in some renderers we might not shrink GPU buffers when we reuse a previous [CxGpuGeometry].

Implementations

impl GpuGeometry

pub fn new(cx: &mut Cx, geometry: Geometry) -> Self

Create a GpuGeometry from a Geometry.

Trait Implementations

impl Clone for GpuGeometry

fn clone(&self) -> GpuGeometry

Returns a copy of the value.

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

Performs copy-assignment from source.
