These pictures have been rendered on an MFD in-game. It uses a type of raytracing to find where the pixel will intersect the terrain and calculates its color and shading. It takes about 1 second to render a low res image of 32x32 pixels, but it takes about 10 minutes to render 1024x1024






@GoldenShadowGS Unity added ray casting, but it hasn’t been added to SR2, tho. They might put it into a Vizzy, thing, but I don’t know.
