Implementations

impl K3dengine

pub fn render_painters_algorithm<'a, MS, F>( &self, meshes: MS, triangles: &mut Vec<DepthSortedTriangle>, callback: F, ) -> usize

where MS: IntoIterator<Item = &'a K3dMesh<'a>>, F: FnMut(DrawPrimitive),

Render using Painter’s Algorithm (back-to-front sorting, no Z-buffer)

Collects all triangles, sorts them by depth, and renders back-to-front. This eliminates the need for a Z-buffer, saving significant memory.

Arguments

• meshes - Iterator of meshes to render
• triangles - Buffer to store sorted triangles (must be large enough!)
• callback - Drawing callback for each primitive

Returns

Number of triangles rendered

impl K3dengine

pub fn new(width: u16, height: u16) -> K3dengine

pub fn set_caps(&mut self, caps: ProfileCaps)

pub fn clear_caps(&mut self)

pub fn set_quality_tier(&mut self, tier: QualityTier)

pub fn set_material_profile(&mut self, profile: MaterialProfile)

pub fn apply_render_defaults(&mut self, defaults: RenderDefaults)

pub fn transform_points<const N: usize>( &self, indices: &[usize; N], vertices: &[[f32; 3]], model_matrix: Matrix4<f32>, ) -> Option<[Point3<i32>; N]>

pub fn transform_points_with_w<const N: usize>( &self, indices: &[usize; N], vertices: &[[f32; 3]], model_matrix: Matrix4<f32>, ) -> Option<([Point3<i32>; N], [f32; N])>

Like transform_points but also returns clip-space W values for perspective-correct UV.

pub fn execute<D, const MAX: usize>( &self, fb: &mut D, frame: &mut FrameCtx<'_>, commands: &CommandBuffer<MAX>, telemetry: Option<&mut ExecuteTelemetry>, ) -> Result<Option<DirtyRegion>, RenderError>

where D: DrawTarget<Color = Rgb565> + OriginDimensions, <D as DrawTarget>::Error: Debug,

pub fn execute_tiled<D, const MAX: usize, const BIN_CAP: usize>( &self, fb: &mut D, frame: &mut FrameCtx<'_>, commands: &CommandBuffer<MAX>, tile: TileConfig, ) -> Result<TileBinStats, RenderError>
