Is FilledPath rasterization still using CPU in OpenGL package

Question

Hello experts,

Background is I'm using 9.30 OpenGL package.

I made a demo of some high resolution up to 3K. A big portion of screen is for rendering a FilledPath.

Running on target board I find that CPU loading is high while fps is low.

Are we using CPU for rasteriztion vectors? Or is there any plan to take advantage of OpenGL to do the job?

Best Regards.

Hello,

your observation is correct. The vector rasterization is performed per CPU and the results are stored within an OpenGL texture. For the moment we don't plan to implement the vector rasterization in OpenGL. Due to the features supported in Embedded Wizard the adaption would require complex polygon calculations in advance. This will also have an impact on the CPU load.

Does it help you further?

Best regards
