From 91e9ad92f5f78dd1578df46205f028599f095357 Mon Sep 17 00:00:00 2001 From: Yaohua Xiong Date: Thu, 24 Nov 2022 20:43:34 +0800 Subject: Refactor baking code for Curve2D The main change is to caculate tangent directly from bezier curve, without going through discretized polyline, avoiding pitfalls of discretization. A similar refacor had been applied to Curve3D. The test cases for Curve2D is updated, comparing floating point with is_equal_approxmiate() instead of `==`, in order to avoid float precision problem. --- tests/scene/test_curve.h | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'tests/scene/test_curve.h') diff --git a/tests/scene/test_curve.h b/tests/scene/test_curve.h index 36ec0c0a4d..4afd5b293f 100644 --- a/tests/scene/test_curve.h +++ b/tests/scene/test_curve.h @@ -31,6 +31,7 @@ #ifndef TEST_CURVE_H #define TEST_CURVE_H +#include "core/math/math_funcs.h" #include "scene/resources/curve.h" #include "tests/test_macros.h" @@ -229,7 +230,7 @@ TEST_CASE("[Curve2D] Linear sampling should return exact value") { for (int i = 0; i < len; i++) { Vector2 pos = curve->sample_baked(i); - CHECK_MESSAGE(pos.x == i, "sample_baked should return exact value"); + CHECK_MESSAGE(Math::is_equal_approx(pos.x, i), "sample_baked should return exact value"); } } @@ -245,7 +246,7 @@ TEST_CASE("[Curve3D] Linear sampling should return exact value") { for (int i = 0; i < len; i++) { Vector3 pos = curve->sample_baked(i); - CHECK_MESSAGE(pos.x == i, "sample_baked should return exact value"); + CHECK_MESSAGE(Math::is_equal_approx(pos.x, i), "sample_baked should return exact value"); } } -- cgit v1.2.3
