Struct three_d::renderer::ForwardPipeline

pub struct ForwardPipeline { /* private fields */ }

Forward render pipeline which can render objects (implementing the Object trait). Forward rendering directly draws to the given render target (for example the screen) and is therefore the same as calling Object::render directly.

Implementations

impl ForwardPipeline

pub fn new(context: &Context) -> ThreeDResult<Self>

Constructor.

pub fn render_pass(
    &self,
    camera: &Camera,
    objects: &[&dyn Object],
    lights: &[&dyn Light]
) -> ThreeDResult<()>

Render the objects. Also avoids rendering objects outside the camera frustum and render the objects in the order given by cmp_render_order. Must be called in a render target render function, for example in the callback function of Screen::write.

pub fn depth_pass(
    &self,
    camera: &Camera,
    objects: &[&dyn Object]
) -> ThreeDResult<()>

Render the distance from the camera to the objects in each pixel into a depth texture. Also, do not render transparent objects and objects outside the camera frustum. Must be called in a render target render function, where a depth texture is bound, for example in the callback function of Screen::write or DepthTargetTexture2D::write.

pub fn depth_pass_texture(
    &self,
    camera: &Camera,
    objects: &[&dyn Object]
) -> ThreeDResult<DepthTargetTexture2D>

Creates a new DepthTargetTexture2D, applies a ForwardPipeline::depth_pass and returns the texture.
