heligun

3D helicopter shooter with raytraced terrain for Emscripten

Description

Heligun is a game based on the Comanche series by NovaLogic. The player takes control of an attack helicopter to complete missions and battle with other attack helicopters.

The terrain is generated using a similar technique found in Comanche where a ray is cast from the viewpoint to a heightmap as an alternative to vectorized graphics which were computationally expensive in 1992 (http://simulationcorner.net/index.php?page=comanche). Heligun uses raymarching to draw the terrain which is run on the GPU in parallel for each pixel.
