voxel-fakeao

Apply a naive ambient occlusion to geometry faces.

Currently this just gradients horizontal faces dark to light, top faces light and bottom faces dark. Could definitely be better but hey it's fake.

example

var fakeao = require('voxel-fakeao')(game);

// Apply fakeao to every chunk
game.on('renderChunk', function(chunk) {
  fakeao.onChunk(chunk);
});

// Or apply to a specify geometry
fakeao.onGeometry(mesh.geometry, '#ff0000');

// Or specific faces
for (var i = 0; i < geometry.faces.length; ++i) {
  fakeao(geometry.faces[i], '#dddddd', (Math.random() * 0xffffff)|0);
}

api

var fakeao = require('voxel-fakeao')(game)

fakeao(face, [light, dark])

Will apply gradient between light and dark onto the face. If light is omitted it will use the existing face color. If dark is omitted then it will be automatically calculated at 10% darker than light.

fakeao.onGeometry(geometry, [light, dark])

Apply to all the faces of a geometry.

fakeao.onChunk(chunk, [light, dark])

Apply to all the faces of a geometry on a chunk.

install
