Re: [Kicad-developers] How to make single-plane .cpp from .png?

[Johannes Sprigode]

Thanks Nick, that made the resulting cpp files even smaller thanks to
pngcrush!

[Kicad-developers] Coding style question

[Tomasz Wlostowski]

Hi Fellow Devs,

I'm fixing some memory management issues in the P by introducing smart
pointers here and there. Do we have any coding policy on typedefing
shared_ptrs/unique_ptrs?

Should I:
- always use std::shared_ptr explicitly?
- or am I allowed to typedef std::shared_ptr TYPE_SP (or something
alike)?

Cheers,
Tom

Hi Jeff,

IIRC selected items are never cached in GAL, at least in pcbnew (select
moves them to m_selection which is a non-cached VIEW_GROUP).

Re: [Kicad-developers] GAL layer question

[Jeff Young]

Hi Tom,

I don’t know a thing about them but it’s probably time I bone up on this whole 
OpenGL thing anyway, so I’ll look into it.

Cheers,
Jeff.

Hi Jeff,

How about using a shader for drawing selection highlights/overlays in
OpenGL (fallback has no distinction between cached/noncached anyway)?

Re: [Kicad-developers] Anyone know where the sources to the simulation cursors are?

[Jeff Young]

Hi Orson,

I needed to make a current-probe, so I created a new voltage-probe to match.

Try the SPICE probe out and see what you think.  (You should get a 
voltage-probe over wires and a current-probe over pins.)

Cheers,
Jeff.

Hi Orson,

I wanted to keep the selection highlight shadows uncached, but they need to go 
above the device backgrounds and sheet backgrounds.

I can go ahead and put them in cached.  (I just need to add some code to redraw 
them when the zoom level changes.)

Cheers,

Re: [Kicad-developers] 5.1.3 release

[Nick Østergaard]

Yes. There is an issue on the 5.1.3 of kicad-doc that and we need to
include the fix for that in 5.1.4 and test it.

Is there any reason why we haven't tagged the doc and i18n repos yet?
The 5.1.4 tag should be the same commit as 5.1.3.  I can do it if the
need be.

Still waiting for doc and i18n to be tagged.  Someone please tag them so I can

Re: [Kicad-developers] GAL layer question

[Maciej Suminski]

Hi Jeff,

I am afraid it is not possible. We use two framebuffers for rendering:
the cached one keeps in the video memory vertices that are not likely to
change in the near future, the non-cached is for vertices that are
modified (e.g. dragged tracks) and are send to the GPU every frame.

To boost the performance even further, the framebuffers take advantage
of composition. The framebuffers are rendered to textures, then they are
blitted on the screen: first cached, then non-cached. Thanks to that,
the cached framebuffer might be reused for many frames when only
non-cached items are updated, but the drawback is that one cannot
interleave the rendering order.

Is there a particular problem you are trying to solve? Perhaps it can be
implemented in another way.

Cheers,
Orson
