Converts shapes to WebGL entities and Set of missing texture filenames

import WebGL
import WebGL.Shape2d


main =
    WebGL.Shape2d.toEntities Dict.empty 100 100 [ rectangle red 30 30 ]
        |> Tuple.first
        |> Webgl.toHtml [ width 100, height 100 ]

Main building block

rectangle : Vec3 -> Float -> Float -> Shape2d
rectangle color width height =
    Shape2d
        { x = 0
        , y = 0
        , a = 0
        , sx = 1
        , sy = 1
        , o = 1
        , form = Form width height (Render.rect color)
        }

Render is part of Shape2d that converts Shape2d into Entity

rect : Vec3 -> Render
rect color uP uT opacity =
    WebGL.entity
        Shader.vertNone
        Shader.fragFill
        Shader.mesh
        { color = setAlpha color opacity
        , uP = uP
        , uT = uT
        }
