Scissor Rect in 3D2D

[Ziks]

Is there a way to set a scissor rect local to a 3D2D camera orientation?

Example: In the following case I would like the green circle to be clipped so it is only inside the grid rectangle area.

If it isn't possible I have an alternative, although it will require a lot of work and would be less efficient.

Stencil should do.

Awesome, thank you!

My solution:

function GUI:Draw()
    render.ClearStencil()
    render.SetStencilEnable(true)

    render.SetStencilFailOperation(STENCILOPERATION_KEEP)
    render.SetStencilZFailOperation(STENCILOPERATION_REPLACE)
    render.SetStencilPassOperation(STENCILOPERATION_REPLACE)
    render.SetStencilCompareFunction(STENCILCOMPARISONFUNCTION_ALWAYS)
    render.SetStencilReferenceValue(1)

    surface.SetDrawColor(Color(0, 0, 0, 255))
    surface.DrawRect(self:GetGlobalRect())

    render.SetStencilCompareFunction(STENCILCOMPARISONFUNCTION_EQUAL)
    render.SetStencilPassOperation(STENCILOPERATION_REPLACE)

    -- Drawing screen stuff 

    render.SetStencilEnable(false)

    self.Super[BASE].Draw(self)
end
