Loading 3D without Craft

ambientocclusion

Hello!

I would like to know if it’s possible to load and render 3D models from the built in assets library in my project without using the Craft library. I am using tiny-ecs and I constructed a little 2D game but I would like for my next project to continue to use tiny-ecs and be able to load models without having to call any Craft code. Any idea of how I’d do this?

@ambientocclusion Here’s an example of 3D without Craft.

displayMode(STANDARD)

function setup()
    print("Slide output window down")
    parameter.integer("R",-360,360, -170)
    parameter.number("x",0,1,.5)
    parameter.number("y",0,1,.5)
    parameter.number("z",0,1,.5)
    parameter.integer("sizex", 0, 50, 20)
    parameter.integer("sizey", 0, 50, 20)
    parameter.integer("sizez", 0, 50, 20)
    c = { color(255, 0, 0, 255), color(0, 255, 0, 255), 
          color(255, 243, 0, 255), color(0, 0, 255, 255), 
          color(255, 255, 255, 255), color(255, 0, 189, 255)}                    
    colors = {}
    for i = 1, 6 do
        for j = 1, 6 do
        table.insert(colors,c[i])
        end
    end    
end

function draw()
    background(0, 0, 0, 255)
    perspective(50)
    camera(-500,0,0,0,0,0,0,1,0)
    rotate(R,x,y,z)
    cube(0,0,0,sizex,sizey,sizez)
end

function cube(x,y,z,w,h,d)
    local cube = mesh()    
    local v = { vec3(x-w,y-h,z+d),vec3(x-w,y+h,z+d),
                vec3(x+w,y-h,z+d),vec3(x+w,y+h,z+d),
                vec3(x-w,y-h,z-d),vec3(x-w,y+h,z-d),
                vec3(x+w,y-h,z-d),vec3(x+w,y+h,z-d) 
              }       
    local faces = { v[1],v[2],v[3],v[2],v[3],v[4],v[2],v[4],v[6],v[4],v[6],v[8],
                    v[1],v[2],v[5],v[2],v[5],v[6],v[3],v[4],v[7],v[4],v[7],v[8],
                    v[1],v[3],v[5],v[3],v[5],v[7],v[5],v[6],v[7],v[6],v[7],v[8] 
                  }                     
    cube.vertices = faces
    cube.colors = colors
    cube:draw()
end

Right but my question is: is it possible to load one of the meshes from the assets and display that without Craft? I’d like to use one of the characters or environment models, or load my own.
