Assessing the insertion of any object through an opening
with composite rotations and translations in 3D space


I hope that sounds impressive.


Back in 2017, A client husband & wife wanted to move their enormous and very heavy couch from their first-floor living room to their second-floor study.

They didn't want to assemble a crew to struggle with it going up the stairway only to find that it wouldn't fit through the door to their study.

They suggested I write a computer program to model "rotational insertion of 3D object through opening" (or something like that).

I told them it would be too much programming work. Hours later I changed my mind, sat down with some existing RogCAD code.. and had the new feature working in a matter of minutes!

The software is shown in the video box below, which I used to analyze the couch-moving back in 2017.

2023: I did a lousy job of "couch-moving" in the demo below. Of course I did a great job every single time back in 2017 -- when I didn't have the screen-recorder going. Just use your imagination. My program also allows for a side view. Only the overhead view and the variable 3D perspective view are utilized in the video below.

2023:

This past week, I've added the same
feature for general use in RogCAD.

Two other upgrades this past week are:

1__ Gradient lighting on curved surfaces now gets automatically adjusted as one's perspective changes. Previously, gradient lighting was automatic for just one perspective at a time.

2__ Real-time navigation can now be had in "surface-model" mode as opposed to mere "wire-frame" mode, with both the usual perspective-change navigation and the new rotation routine (which can be applied to selected portions of the database).
