Building Lore

If you decide not to use the ready-to-go scripts in dist, you can (edit and) build the project by running:

npm install
gulp

Getting Started

A simple example can be found in the example folder. The example data file was downloaded from the website of the Berkeley Drosophila Transcription Network Project. It is a very small data set (N=6000) chosen because of the small file size (larger files can not be hosted on github).

{
    position: new Lore.Vector3f(),
    axis: {
        x: {
            length: 50.0,
            color: Lore.Color.fromHex('#222222')
        },
        y: {
            length: 50.0,
            color: Lore.Color.fromHex('#222222')
        },
        z: {
            length: 50.0,
            color: Lore.Color.fromHex('#222222')
        }
    },
    ticks: {
        enabled: true,
        x: {
            count: 10,
            length: 5.0,
            offset: new Lore.Vector3f(),
            color: Lore.Color.fromHex('#1f1f1f')
        },
        y: {
            count: 10,
            length: 5.0,
            offset: new Lore.Vector3f(),
            color: Lore.Color.fromHex('#1f1f1f')
        },
        z: {
            count: 10,
            length: 5.0,
            offset: new Lore.Vector3f(),
            color: Lore.Color.fromHex('#1f1f1f')
        }
    },
    box: {
        enabled: true,
        x: {
            color: Lore.Color.fromHex('#222222')
        },
        y: {
