Draw3D (Mibo.Raylib)

Draw3D Module

Namespace: Mibo.Elmish.Graphics3D
Assembly: Mibo.Raylib.dll

Pipe-friendly drawing DSL for 3D rendering. Each function takes a RenderBuffer3D as its last argument, adds the corresponding command, and returns the buffer for chaining.

Commands are built via Command3D and added to the buffer.

Usage:

 buffer
 |> Draw3D.beginCamera worldCamera
 |> Draw3D.drawModel model transform
 |> Draw3D.addPointLight { Position = pos; Color = Color.White; Intensity = 1f; Radius = 10f; CastsShadows = false; ShadowBias = ValueNone }
 |> Draw3D.endCamera
 |> Draw3D.drop

union case ValueOption.ValueNone: ValueOption<'T>
