Hi, about two years ago I asked you about the quality of 2D rendering when using hardware acceleration in the chart component(https://www.nevron.com/Forum/12855/Graphical-quality-when-using-RenderSurface-Window). I was then told that you were working on a new 2D renderer for the chart and that the new version would be released in early 2020. Now in early 2021 there has still not been a new release. Seeing the release of the new version of your Open Vision product, that includes hardware rendering, I was hoping that this would be the new 2D renderer and that the .Net Chart would be updated as well. 

What are your plans for the .Net Chart? Is a new version still in the making( including a new 2D renderer )?

Hi Jens,

We're sorry for the delay in the new NOV/.NET Vision releases, but they were caused by some technical difficulties we met with the implementation of the 2D engine in NOV. In particular, the path we chose initially for stroke rendering was using vertex/fragment shaders, but it did not yield the performance improvements we were hoping for in addition to the complexity in dashed lines with antialiasing, so we switched to a combination of CPU/GPU processing there.

Currently, the team is working on improving the 3D performance in the chart using features present in more recent versions of OpenGL (geometry shaders in particular) the primary goal being the surface series, bars, and point rendering in 3D. The performance improvements we see are 10x to 30x so dynamic surfaces with 30 million points will be no problem. If time allows we'll retrofit parts of the 2D engine of NOV in the .NET chart (Nevron Chart already uses text rendering from NOV in hardware-accelerated mode).

We hope this clarifies the current direction of development - if you have any questions or would like more information about specific features or implementation please let us know.

Best Regards,
