The Waveform, Vectorscope and Histogram panels were black when running on
the Vulkan / backend-neutral render path because ScopeBase::OnPaint()
returned early with a TODO. The viewer emits GPU textures that live in the
viewer's own renderer; on Vulkan each ManagedDisplayWidget has a separate
device, so those textures cannot be sampled directly.
Fix by:
- Adding a backend-neutral branch in ScopeBase::OnPaint() that downloads the
reference texture (cross-renderer if needed), color-manages it into a U8
offscreen texture, downloads it to a QImage, and draws via QPainter.
- Adding a pure virtual DrawScopeSoftware() to ScopeBase and implementing it
for WaveformScope, VectorscopeScope and HistogramScope.
- Fixing the managed_tex_up_to_date_ flag that was never set to true in the
OpenGL path, which caused the color-managed scope texture to be recreated
on every paint.
All gtest suites pass.
Yep, this is another one of my "famous" sweeping rewrites. Expect things to break.
Goals for this are:
- Greatly simplify node connections (particularly with arrays) so the code requires less maintenance/is more stable
- Redesign node structure to address issues where UI would stall for lengthy periods of time
- Less reliance on shared ptrs/greater reliance on QObject system for inheritance/memory management
- General code cleanup and improvements
The macro defined namespaces confused the hell out of lupdate and more or less broke translations permanently. Looks like the only way we can do it is to have a hardcoded namespace, which goes against my instinct, but honestly how likely is it that we'll change the namespace anyway (I guess forks might want to do it, but that's their problem ;) )
- Abstracts all OpenGL functionality including UI objects
- Cleans up several rendering codepaths
- Improves threading functionality
- Removes old code and problematic functions
Fixes:
* Values exceeding the encoded range.
Future may account for a certain range
above and below current values.
* Minor calculation problem that prevented
the above fix from working properly.
* Streamlined the shader code.
* Add a vertex shader to handle the scaling.
* Use the viewport resolution as the scaled
version to save performance.
