Lookat them weird trails, Lolz

Creating A LemonTrail

To create a new trail:

var myTrail = new LemonTrail(_age, _initial_force_vector, _initial_force_strength, _quad_interval);

Creating LemonTrail Shapes

Create trail spawning shapes such as squares, hexagons, and other radially symmetrical shapes using thecreateShape function inside of your trail. This allows you to define the radius, number of points, color, and the animation curve to use for the profile of your trail:

// Note: This method is not idea as it requires you to create a custom transformation matrix
// for these shapes in order to attach them to your meshes properly, which can be a very daunting task.
// Instead we recommend importing your LemonTrails from Blender!
var shape = myTrail.createShape(_radius, _num_points, _color, _animCurve);

Updating and Drawing LemonTrail

Update the positions of the shapes and draw them using the updateTrail and drawTrail functions respectively:

Updating the Trail

// Update the trail
myTrail.updateTrail();

Drawing the Trail

// Draw the trail, Call this after setting the transformation matrix for your mesh
myTrail.drawTrail(_tex, _shader);

Importing LemonTrail Data

Import LemonTrail data using the LemonTrail_import function. This parses a JSON file created by our Blender exporter:

// Import LemonTrail data from a file var shapes = LemonTrail_import(myTrail, _file_path, _color, _animCurve);

With Blender, you can attach several trails to a single mesh!
