Struct Transform

pub struct Transform { /* private fields */ }

A Transform, when applied, modifies a mesh. When applied to a rule, it transforms all the meshes that rule eventually expands to. Transforms may be translations, scales, rotations, etc.

It may be helpful to think of transforms to rules as transforming the space in which the rule or mesh is evaluated. For example this rule will translate a cube 4.0 on the x axis in our root frame of reference:

let our_translated_cube = Rule::new().push(Tf::tx(4.0), cube());

This rule will translate a cube -4.0 on the x axis in our root frame of reference:

let containing_rule = Rule::new().push(Tf::ry(180.0), our_translated_cube);

This rule will translate a half-sized cube 2.0 on the x axis in our root frame of reference.

let containing_rule = Rule::new().push(Tf::s(0.5), our_translated_cube)

Implementations
