render.RencerView cut to a filled circle

[poepel]

Hi :D
can i cut a rect to a circle
when i use

render.RenderView

i made a minimap with render.Renderview but i want it as a circle not a rect
how can i do this?

It's possible using stencils, but I'm too stupid to know how those work, so I can't really explain them here :/

Here's a tutorial on stencils:

If you can understand that, then you know that all you need to do is invisibly draw a circle as the render mask: [url]https://wiki.garrysmod.com/page/surface/DrawPoly[/url]

(by this means you can hide the part of the rectangular minimap that is outside of a circular region on screen)

you might also want to remove the 3D2D lines from the examples and also change the hook from PostDrawOpaqueRenderables to HUDPaint

yeah i know that i use stencil, but i cant understand it
where i put the render.Renderview :(

If you are having problems with render view, oh boy, you're too fresh to start with stencils :v

my render.renderview works
(minimap)

but i dont know how to add the stencil on render.renderview
nothing happen when i put it between the code :(

maybe because it is no draw. ... function?

local win = {}

	win.h = 300

	local CamData = {}
	CamData.angles = Angle(90,LocalPlayer():EyeAngles().yaw,0)

	CamData.x = (ScrW()/2)-(win.w/2)

	CamData.orthoright = 2000
	CamData.orthotop = -2000
	CamData.orthobottom = 2000

	render.ClearStencil()
	render.SetStencilEnable(true)
		render.SetStencilWriteMask(255)
		render.SetStencilTestMask(255)

		draw.RoundedBox(0,(ScrW()/2)-100,ScrH()-100,200,200,Color(255,255,255))

		render.SetStencilCompareFunction(STENCILCOMPARISONFUNCTION_EQUAL)
		
		draw.RoundedBox(0,(ScrW()/2)-200,ScrH()-200,400,200,Color(0,0,0))
		render.RenderView( CamData )

	render.SetStencilEnable(false)

this works only for draw.Roundedbox not render.renderview() :(

what is my mistake?

ok it only works with draw or surface but not with render.renderview() right?
