i'm trying to draw a sphere (creating a jit.gl.sketc inside jit.gl.lua) but i'm stuck to not being able to erase correctly the jit.gl.render.

Here for example I can see the increment of the radius but I can't see a decrement cause the image is not erased!

sketch = jit.new("jit.gl.sketch", this.drawto)

Hello everybody,
i'm trying to draw a sphere (creating a jit.gl.sketc inside jit.gl.lua) but i'm stuck to not being able to erase correctly the jit.gl.render.
Here for example I can see the increment of the radius but I can't see a decrement cause the image is not erased!

function radius(x)
x = x
sketch = jit.new("jit.gl.sketch", this.drawto)
sketch.lighting_enable = 1
sketch:sphere(x)
end

dynamic drawing using jit.gl.lua controlling jit.gl.sketch
