How to model a radarscreen

Hi,

i would like to compose a ‘beam’ like u can see below within the blender render compositor. With the help of the screw modifier i came up with the beginning but i have no idea how to properly compose the fade effect on it.




any help would be appreciated.

managed to get in done in cycles, saved it als png with alpha and imported it in blender render by image on plane. Still like to know how to appropriate accomplish this in de composer.

so this is a OLD analog green CRT radar screen from the mid 40’s to 80’s

you are looking at the current radar screen right now - a lcd

i wan’t to create something similar in Blender Render like I created in Cycles. Please have a look at the file below;

Hey there’s a blend texture type that is exactly this shape. Just map it to a plane and rotate the plane (or the texture if you prefer)
