Dodotree / throttle.js
Last active November 23, 2022 18:23
Minimalistic JS throttle function to limit calls to any callback function to "once per Nms", most useful with N between 100-300. Can be used on the back end too depending on time delay functions available.
const throttle = (delayFunc, cancelFunc) => (callback, delay) => {
let lastFunc
let lastExecTime
return function (...args) {
const context = this
const elapsed = Date.now() - lastExecTime
function execCallback () {
lastExecTime = Date.now()

Dodotree / vanilla_time_funcs.js
Created July 11, 2021 05:17
Js small time lapse printing and detection of saving time on top of time zone difference
//Example: timeLapseToString(new Date()-t0);
function timeLapseToString(lapse_int) {
let lapse = new Date(lapse_int);
return `${lapse.getUTCHours()}:${lapse.getUTCMinutes()}:${lapse.getUTCSeconds()}`;
}
function getSavingTimeMin() {
let mins = (new Date("Thu, 01 Jan 1970 00:00:00") - new Date("Thu, 01 Jan 1970 00:00:00 GMT"))/(60*1000);
let ofs = new Date().getTimezoneOffset();

Dodotree / bestFitAngle.py

Blender3D script to find best fit box angle

After rotation bounding box will have minimum volume

Dodotree / blender_bb_collision.py
Last active September 2, 2023 18:39
import bpy, bmesh
from mathutils import Vector
'''
For simple situations where boxes are not rotated and you only need to detect overlap in bounding boxes
'''
def boundingBoxCollide(c1, c2):
bb = [c1.matrix_world * Vector(corner) for corner in c1.bound_box]
bb2 = [c2.matrix_world * Vector(corner2) for corner2 in c2.bound_box]

Dodotree / blender_bounding_box.py
Created May 15, 2018 23:26
import bpy, bmesh
from mathutils import Vector
'''
Several problems solved:
1) no need to activate or select the object
2) no need to change origin after bpy.ops.object.transform_apply(location=True, rotation=True, scale=True)
3) only 2 walls to check inside
