🖌 spoly

A tiny Garry's Mod library that allows you to render different shapes without jagged edges.

Not only your shapes will look better, but the performance will increase, since basically you render an icon instead of rendering high polygon shapes.

Example

Smooth shapes for Circles.lua

spoly.DrawCircle = spoly.Generate('circle', function(w, h)
    local x0, y0 = w * .5, h * .5
    local radius = h * .5
    local circle = Circles.New(CIRCLE_FILLED, radius, x0, y0)

    circle()
end)

spoly.DrawOutlinedCircle = spoly.Generate('circle_outline_256', function(w, h)
    local x0, y0 = w * .5, h * .5
    local radius = h * .5
    local thickness = 256
    local circle = Circles.New(CIRCLE_OUTLINED, radius, x0, y0, thickness)

    circle()
end)

hook.Add('HUDPaint', 'Test', function()
    surface.SetDrawColor(color_white)

    local y = 512
    local x = 512
    local space = ScreenScale(1)

    local amount = 8
    local multiplier = 16
    local maxSize = multiplier * amount

    for i = 1, amount do
        local size = multiplier * i

        spoly.DrawOutlinedCircle(x, y + maxSize * .5 - size * .5, size, size)

        x = x + size + space
    end

    y = y + maxSize + (space * 10)
    x = 512

    for i = 1, amount do
        local size = multiplier * i

        spoly.DrawCircle(x, y + maxSize * .5 - size * .5, size, size)

        x = x + size + space
    end
end)

Demonstration

The white shapes are drawn using the library. The red ones are drawn by the default method surface.DrawPoly.
