In its current state, the Polymost renderer in ZDoom can only render world geometry, either in wireframe or in solid colors. It can be tested by setting r_polymost to 1 (wireframe), 2 (solid colors with wireframe) or 3 (solid colors without wireframe) in the console.
- It is overlaid on the software renderer output. In wireframe mode, it is still playable; but in solid colors mode, the polygons mask the normal view entirely, rendering actors invisible.
- Since it is part of the software renderer, if you use the OpenGL renderer from GZDoom or Skulltag, this will have no effect.
The two screenshots illustrate the difference between Doom's horizontal projection and the true 3D perspective of polymost.gtang. It corresponds to the global tilt angle, in . Positive values tilt the angle clockwise, negative values tilt it counter-clockwise. With an approximation of π (positive or negative), the projection is upside-down.
