From 3bafa9bd82dbcd125a75e796f8b78ab63a560422 Mon Sep 17 00:00:00 2001 From: Scott Worley Date: Wed, 21 May 2014 00:59:14 -0700 Subject: [PATCH] Use a params object rather than loose arguments Otherwise, making subroutines is tedious -- each function has to accept a bunch of loose args only to pass them along. Adding a parameter that in only used in a subroutine required changing all the callers all the way up the stack. --- box_by_extrude.html | 12 +++++------ box_by_faces.html | 20 +++++++++--------- box_by_quadstrip.html | 20 +++++++++--------- box_by_rotation.html | 12 +++++------ box_by_trianglefan.html | 20 +++++++++--------- cone_primitive.html | 10 ++++----- medusa.html | 36 ++++++++++++++++---------------- nt3d.js | 19 +++++++++++++---- rmm.html | 46 ++++++++++++++++++++--------------------- serrated.html | 42 ++++++++++++++++++------------------- sphere_primitive.html | 10 ++++----- torus_by_extrude.html | 18 ++++++++-------- wrap_sphere.html | 38 +++++++++++++++++----------------- 13 files changed, 156 insertions(+), 147 deletions(-) diff --git a/box_by_extrude.html b/box_by_extrude.html index fb1ca2c..62dca74 100644 --- a/box_by_extrude.html +++ b/box_by_extrude.html @@ -3,17 +3,17 @@ Box by extrude diff --git a/box_by_faces.html b/box_by_faces.html index b27d795..938c8e8 100644 --- a/box_by_faces.html +++ b/box_by_faces.html @@ -3,15 +3,15 @@ Box by faces diff --git a/box_by_quadstrip.html b/box_by_quadstrip.html index 83ad5ab..ede01d9 100644 --- a/box_by_quadstrip.html +++ b/box_by_quadstrip.html @@ -3,21 +3,21 @@ Box by quadstrip diff --git a/box_by_rotation.html b/box_by_rotation.html index d575a42..e39394e 100644 --- a/box_by_rotation.html +++ b/box_by_rotation.html @@ -3,11 +3,11 @@ Box by rotation diff --git a/box_by_trianglefan.html b/box_by_trianglefan.html index 7c0519c..3090d4a 100644 --- a/box_by_trianglefan.html +++ b/box_by_trianglefan.html @@ -3,20 +3,20 @@ Box by trianglefan diff --git a/cone_primitive.html b/cone_primitive.html index 19a7686..ef044fd 100644 --- a/cone_primitive.html +++ b/cone_primitive.html @@ -3,12 +3,12 @@ Cone primitive diff --git a/medusa.html b/medusa.html index e82d9e5..69ea3ba 100644 --- a/medusa.html +++ b/medusa.html @@ -3,19 +3,19 @@ Medusa diff --git a/nt3d.js b/nt3d.js index d4e62f6..80390b9 100644 --- a/nt3d.js +++ b/nt3d.js @@ -421,14 +421,14 @@ nt3d = { setTimeout(function() { // Get params from form - var params = []; + var params = {}; for (var i = 0; i < this.user_params.length; i++) { var as_string = this.form.elements["param"+i].value; var as_num = +as_string; - params[i] = isNaN(as_num) ?
