futracer

Race through breathtaking 3-D graphics with Futhark through OpenCL (not OpenGL)!

Run make to build the library, and then run ./futcubes.py, ./futfly.py, or ./futdoom.py to run the example programs. Use the --help argument to see which settings exist.

There are three rendering approaches: segmented (the default) chunked, and scatter_bbox. The segmented approach is a rasterizer, while chunked and scatter_bbox are raycasters.

Dependencies

futracer depends on the programming language Futhark; see http://futhark-lang.org/ and https://github.com/HIPERFIT/futhark.

futracer also depends on PyGame, PyPNG (only futcubes.py and futdoom.py), and NumPy.

Keyboard controls

Use the arrow keys for now. Use Page Down and Page Up to decrease and increase the view distance for rendering (fun!). Use 1 and 2 to decrease and increase the draw distance.

Use R to switch rendering approaches.

For the chunked rendering approach, use A and D to decrease and increase the number of draw rectangles on the X axis, and W and S on the Y axis. Sometime in the future this should be chosen automatically. Warning: This might slow down the program to a crawl for some reason.

Scripts

futdoom.py supports custom maps. For an example of a (poorly) randomly generated map, run:

./futdoomlib/scripts/generate_random_map.py | ./futdoom.py --auto-fps --level -
