Eagle::Renderer3D
Reference
Object

Overview

The forward renderer: shadow pass, sky, opaque meshes, then transparent meshes.

The scene tree drives it through Scene3D.render. Call #render directly to draw meshes without nodes, for tools and special effects.

Defined in:

eagle/graphics3d/renderer3d.cr

Constructors

.new(environment : Environment = Environment.new)
Creates a renderer.

Instance Method Summary

#dispose : Nil
Frees GPU resources.
#draw_calls : Int32
Same as #stats_draw_calls.
#environment : Environment
The settings used when rendering.
#environment=(environment : Environment)
The settings used when rendering.
#light_matrix : Mat4
The light-space matrix used for shadows.
#render(camera : CameraView, items : Array(DrawItem), lights : Array(LightData), target_size : Vec2, flip_y : Bool = false, clear : Bool = true) : Nil
Renders items lit by lights from camera into the current target.
#shadow_texture : Texture | Nil
The shadow map from the last render, for debugging.
#stats_draw_calls : Int32
Draw calls in the last render.

Constructor Detail

def self.new(environment : Environment = Environment.new) #

Creates a renderer.

Instance Method Detail

def dispose : Nil #

Frees GPU resources.

def draw_calls : Int32 #

Same as #stats_draw_calls.

def environment : Environment #

The settings used when rendering.

def environment=(environment : Environment) #

The settings used when rendering.

def light_matrix : Mat4 #

The light-space matrix used for shadows.

def render(camera : CameraView, items : Array(DrawItem), lights : Array(LightData), target_size : Vec2, flip_y : Bool = false, clear : Bool = true) : Nil #

Renders items lit by lights from camera into the current target. Set flip_y when rendering into a Canvas, and clear to clear color and depth first.

def shadow_texture : Texture | Nil #

The shadow map from the last render, for debugging.

def stats_draw_calls : Int32 #

Draw calls in the last render.
