A question about the application of LVGL combined with opengl #2

Closed Yangyuanxin closed 2 years ago

Yangyuanxin commented 2 years ago

I have a requirement now that I hope lvgl and opengl can be used in combination with each other. Therefore, when using opengl, the device needs to have graphics card requirements. However, I saw the lv_tinygl demo you developed. Does it have to have a hardware GPU to run? ?

In the future, is it possible for lvgl to support opengl? Because 3D display can be carried on a lightweight GUI, in this case, I hope to use the advantages of LVGL to operate 3D models to achieve my product requirements, and at the same time, it can also greatly reduce my resources.

The experiments with TinyGL stopped here due to some issues in TinyGL or with it's integration. :slightly_frowning_face:

Anyway, the OpenGL support can be added independently of LVGL. The "bridge" can be a buffer in which the rendered image is stored and LVGL display's it as an lv_img.
