qtvismach, a axis toolpath

Thanks a lot Aciera, this code example and xyzac-trt-gui.py simulation file helped me a lot.
Now it works the way I wanted.
 

I would also like to achieve transparency.
After basing the axis, the cone is filled with color, without transparency.
Where would I use "BLEND"?

blend is the code that I added to primitives.py

I made a small modification to the code and now it works properly.
 

I was hoping that the toolpath would be visible inside the solid, but this is not the case...


 

Interesting, the tool seems to be cut off too.

May have something to do with 'depth testing' as seen in this image where some of the background scene is not visible through the red tinted glass:

 

The above image comes from this article which may be useful:

[edit]
Just noticed the spelling in the article is a tad strange.

I just used this article today.

I positioned the two pieces for the test behind the workpiece and only the actual head and countertop are visible.
I don't know much about opengl, I guess it can be configured somehow...
 

Maybe the order of the parts can do it.
I see you can see the base and chuck through the material but not the column or other chuck.

probably there is a opengl command to directly set Zdepth but like you i know just enough to get it to mostly work

I will leave the topic of transparency for later, I have an idea how to solve it differently.
Please tell me how to easily read the x and y movement values from the "setup/properties" tab? I need these values to automatically generate the dimensions of the workpiece in the A-axis holder.

The second problem is the disappearing tool path in qtvismach. The same thing happens as in the preview window in qtdragon. A longer toolpath history is needed, or it doesn't disappear at all.
 

You can get them from STATUS, as long as the preview window is in the same python context.
Meaning you would need to have the vismach window embedded in, or loaded from, qtdragon.
The normal qtvcp embedding should work, getting a separate window is custom work.

then:
STATUS.connect('graphics-gcode-properties', lambda w, d: self.update_gcode_properties(d))
would give you the raw information in the function update_gcode_properties().
You can see how it was done in qtdragon_handler.py, but something like this:
 

That's what you suggested, using STATUS.connect.. I can control the position of the A-axis tailstock.

After reloading the next file, the tailstock is positioned in the appropriate place depending on the dimension of the project in the X axis.

Another thing I want is to re-build the dimensions of the workpiece.

Qt_vismach can update the position of an already built object, but I can't do it to re-build a new workpiece.

I tried adding a new class in primitives.py, analogous to HalTranslate, but it doesn't work.

It would also be interesting to be able to change the colors of some elements, depending on the values ​​of different pins.

How to do it?
