From fafaebb051907a848a9406f9da19669c81a83a3b Mon Sep 17 00:00:00 2001 From: Elvis Claros Castro Date: Sat, 26 Sep 2026 20:50:41 -0300 Subject: Translate code, comments and logs to English; English README; configurable paths and env vars Identifiers, docstrings, comments and console messages are now in English. Narration, subtitles and on-screen text stay in Spanish (they are the video content). The Blender <-> Godot physics protocol uses English keys and body prefixes chosen to keep the original creation order, so cached simulations and renders stay bit-identical. The old Spanish environment variable names are still accepted. --- scenes/v10_buffon.py | 92 ++++++++++++++++++++++++++-------------------------- 1 file changed, 46 insertions(+), 46 deletions(-) (limited to 'scenes/v10_buffon.py') diff --git a/scenes/v10_buffon.py b/scenes/v10_buffon.py index 35ee4e0..557d927 100644 --- a/scenes/v10_buffon.py +++ b/scenes/v10_buffon.py @@ -4,13 +4,13 @@ sys.path.insert(0, os.path.dirname(os.path.abspath(__file__))) from manim import * from tiktok import * -D = 1.1 # separacion entre rayas = largo de la aguja -Y0 = 0.35 # raya mas baja +D = 1.1 # line spacing = needle length +Y0 = 0.35 # lowest line NLIN = 5 SEED, N1, N2 = 36, 60, 200 -def tirar(n): +def throw(n): rng = np.random.default_rng(SEED) x = rng.uniform(-3.9, 3.9, n) y = rng.uniform(Y0 + 0.1, Y0 + (NLIN -
