Pyramid

The py and py2 shaders add a layer of voxel on top of voxels matching the selected colour. A voxel is only added when the voxel beneath has adjacent voxels, creating the effect of a pyramid.

• py will only add voxels when the adjacent voxels match the selected color. Whereas, py2 will add voxels if there are adjacent voxels of any color.

Parameters

• If provided, index will be the color index of the added voxels. This parameter is optional; if set to 0, the selected color index is used instead.

Each time the shader is executed, a single layer is added. To add multiple layers at once, use -n to set a number of iterations:

xs -n 50 py
xs -n 50 py2

Axis Modes

When no axis modes are set, the shader will form a square pyramid. However, if either X or Y axis modes are set, the shader will form a pyramid with the slope facing the X or Y axis, respectively. Setting the Z-axis mode has no effect.
