Methods
_rebuildLists()
Rebuild lists for this drawable and notify any parent drawable to do so as well. This ensures each drawable contains an updated, flat list of all the drawables beneath them. This way we save performance by not recursing through each child during draw time, and instead, drawing from the flat list at the level we care about.

add(children)
Add a child drawable to this instance
Parameters:
| Name | Type | Description |
|---|---|---|
children |
Array.<Drawable> | Drawable | child drawables to add |
- Inherited From:
- Source:
addVertices(coords)
Add vertices to this geometry object
Parameters:
| Name | Type | Description |
|---|---|---|
coords |
Array.<Float> | Packed array of floating point coordinats. (e.g. [x1,y1,z1,x2,y2,z2,...xn,yn,zn]) |
- Inherited From:
- Source:
draw()
Base draw method, which should always be called by subclasses. This method will perform any updates to dirty geometry buffers, but does not actually perform any drawing itself.
- Inherited From:
- Source:
drawCircular()
Draws the circular buffer as a line strip,

remove(children)
Remove a child drawable from this instance
Parameters:

|---|---|---|
children |
Array.<Drawable> | Drawable | child drawables to remove |

setShaderPosition(gl, shader)
Set up a vertex shader's modelView and projection matrixes, and assign the position of the vertex buffer for this geometry.
Parameters:
