# Objective - Add gizmos integration for the new `Curve` things in the math lib ## Solution - Add the following methods - `curve_2d(curve, sample_times, color)` - `curve_3d(curve, sample_times, color)` - `curve_gradient_2d(curve, sample_times_with_colors)` - `curve_gradient_3d(curve, sample_times_with_colors)` ## Testing - I added examples of the 2D and 3D variants of the gradient curve gizmos to the gizmos examples. ## Showcase ### 2D  ```rust let domain = Interval::EVERYWHERE; let curve = function_curve(domain, |t| Vec2::new(t, (t / 25.0).sin() * 100.0)); let resolution = ((time.elapsed_seconds().sin() + 1.0) * 50.0) as usize; let times_and_colors = (0..=resolution) .map(|n| n as f32 / resolution as f32) .map(|t| (t - 0.5) * 600.0) .map(|t| (t, TEAL.mix(&HOT_PINK, (t + 300.0) / 600.0))); gizmos.curve_gradient_2d(curve, times_and_colors); ``` ### 3D  ```rust let domain = Interval::EVERYWHERE; let curve = function_curve(domain, |t| { (Vec2::from((t * 10.0).sin_cos())).extend(t - 6.0) }); let resolution = ((time.elapsed_seconds().sin() + 1.0) * 100.0) as usize; let times_and_colors = (0..=resolution) .map(|n| n as f32 / resolution as f32) .map(|t| t * 5.0) .map(|t| (t, TEAL.mix(&HOT_PINK, t / 5.0))); gizmos.curve_gradient_3d(curve, times_and_colors); ``` |
