A surface-of-revolution shape generated by rotating a polyline about an axis.
These are all surface-of-revolution objects based on Lathe.
Replace the smelly diff and scale methods with a single new method dv_dt that handles all the use cases of the removed methods, also simplifying calling code.
Also fix primitive and vertex output stats.
The endpoint should be the end of the last row, not one-past-the-last. This caused a panic if the slice contained the last row of the parent. Made slice_mut() logic identical to slice() which was already correct.
Cannot use chunks_exact(stride) because the last row has length w<=stride. rows() was already correct.
The Index impls already do, so make the get methods consistent.
* new_default -> new * new -> new_from
* Reduce duplicated code * Catch more errors * Better panic messages
1. std 2. libm 3. mm
Add Utah teapot and Stanford bunny models to the set of objects displayed.
Allow lower precision with micromath and fallback.
* Change VecN type aliases to always be in Real<N, B>, generic over B. This better matches their intended semantics as specifically Cartesian vectors. For example, SphericalVec and Vec3 are now always distinct types. * Change vecN functions to be generic over B, matching their respective VecN. This removes the need of most uses of .to(), at the expense of sometimes being unable to infer B. * Turn generic Vec4 to ProjVec4 specifically, with little need for Cartesian 4-vectors at least for now. Remove vec4 functions as unneeded.
