PureCAD - WIP

Posted: Tue Dec 31, 2024 4:11 pm

Hello :D

Ok I don't have advanced my project for PureCAD so much but I am happy to share you my current codes :mrgreen: (a bit old thought)

It is my WIP now, very rough and I hope in progress I will add some finished to features :shock:

Here my code so far :

Code: Select all

; Inspired from opengl swept surface - Phil James 11/2024 
; 'Lathe' function converted from: https://stackoverflow.com/questions/7904281/opengl-rotate-a-curve-about-the-y-axis

; It is different path and it look like to a simple CAD Modeling :)
; 
; Name of software : PureCAD
; Version of software : 0.1
; Date of starting to development : 06/11/2024
; Date of finishing to development : 07/11/2024

1st April is in 4 months.

The code shows only a rotating cube, like all 3GL demos.
What have this todo with CAD?

1st April ... xD

Yes it is a test for working in 3D GL :)

From now it is very rough and I will add it as step by step some feature very simple of CAD Modeling :shock:

Already it is a puzzle for me to create a 3D system in OpenGL :mrgreen: but it is coming soon for adding some function as vertex and face to create a m odel.

@threedslider,

This is a begin ...
Don't give up, there is still a very long way to go before you can call it 2D/3D CAD/CAM ...

@marc_256 : Thanks a lot ! :mrgreen:

@idle : yeah but for now it is difficult to make one maybe later.

@fsw : could you say me a bit more on what it is doing flash-flicker ? Any screenshot for that ?

This would only be seen in a video, as a screen shot only shows a light gray area.
(one would need several screen shots per second to catch different appearances)
The flicker is around several times a second, where the light gray area is switched with a lighter gray or white (hard to say).

I'm on an Apple laptop with Apple Silicon CPU.

Ok but I don't know how to fix that because I don't have Mac... :/

And in addition the OpenGL version on Macs is pretty old...

No worries mate.

@fsw : Ok but you mean the button is due of flash-flicker ? Or The cube itself but I don't think it?

Have you tested from pjay ? viewtopic.php?p=630326#p630326

I am based some on him, is it working for you ?

From the link you provided, both examples on that page work, from pjay and shadoko.

The buttons are constantly visible as they do not flicker, but the drawing area is light gray and flickers brighter.
No objects are seen in the drawing area.

Ok I think the recent Mac doesn't support it very well cause Apple depreciated OpenGL in favor to Metal. Now the OpenGL is legacy for new Mac...
