Struct RenderDataBundle 

pub struct RenderDataBundle {
    pub data: SurfaceResource,
    pub time_to_live: TimeToLive,
    pub instances: Vec<SurfaceInstanceData>,
    pub material: MaterialResource,
    pub render_path: RenderPath,
    /* private fields */
}

A set of surface instances that share the same vertex/index data and a material. Geometry instancing means rendering multiple copies of the same mesh in a scene at once, reusing the same vertex data but with a different world transform each time. This technique can be used for objects such as trees that may need to be repeated many times in a scene. See SurfaceInstanceData for the properties that can change between instances of the bundle.

Fields

data: SurfaceResource

A pointer to shared surface data, such as vertices, triangle indices, and blend shapes.

time_to_live: TimeToLive

Amount of time (in seconds) for GPU geometry buffer (vertex + index buffers) generated for the data.

instances: Vec<SurfaceInstanceData>

A set of instances, each with their own world transform and other properties.

material: MaterialResource

A material that is shared across all instances.

render_path: RenderPath

A render path of the bundle.

Implementations

impl RenderDataBundle

pub fn write_uniforms( &self, view_projection_matrix: &Matrix4<f32>, render_context: &mut BundleRenderContext<'_>, ) -> Option<BundleUniformData>

Writes all the required uniform data of the bundle to uniform memory allocator.

pub fn render_to_frame_buffer<F>( &self, server: &dyn GraphicsServer, geometry_cache: &mut GeometryCache, shader_cache: &mut ShaderCache, instance_filter: &mut F, render_context: &mut BundleRenderContext<'_>, bundle_uniform_data: BundleUniformData, global_uniform_data: &GlobalUniformData, ) -> Result<RenderPassStatistics, FrameworkError>

where F: FnMut(&SurfaceInstanceData) -> bool,

Draws the entire bundle to the specified frame buffer with the specified rendering environment.

Trait Implementations

impl Debug for RenderDataBundle

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
