Struct three_d::PhongDeferredPipeline

pub struct PhongDeferredPipeline {
    pub debug_type: DebugType,
    // some fields omitted
}

Deferred pipeline based on the Phong reflection model supporting a performance-limited amount of directional, point and spot lights with shadows. Supports colored, textured and instanced meshes.

Fields

debug_type: DebugType

Set this to visualize the positions, normals etc. for debug purposes.

Implementations

impl PhongDeferredPipeline

pub fn new(context: &Context) -> Result<Self, Error>

Constructor.

pub fn geometry_pass<F: FnOnce() -> Result<(), Error>>(
    &mut self,
    width: usize,
    height: usize,
    render: F
) -> Result<(), Error>

Render the geometry and surface material parameters of Phong deferred meshes or instanced meshes by calling the render_geometry on either type of mesh inside the render closure. This function must not be called in a render target render function, but needs to be followed by a call to light_pass which must be inside a render target render function.

pub fn light_pass(
    &mut self,
    viewport: Viewport,
    camera: &Camera,
    ambient_light: Option<&AmbientLight>,
    directional_lights: &[&DirectionalLight],
    spot_lights: &[&SpotLight],
    point_lights: &[&PointLight]
) -> Result<(), Error>

Uses the geometry and surface material parameters written in the last geometry_pass call and all of the given lights to shade the Phong deferred meshes or instanced meshes. Must be called in a render target render function, for example in the callback function of Screen::write.
