[osg-users] [3rdparty] ImGui integration

[Florian GOLESTIN]

Hi Everyone,

I was thinking to integrate ImGUI with the non FPP version but I'm not sure how to do it.

Itself, ImGUI render the ui inside a vector of (vector of ) struct containing the triplet Vertex Position, UV coordinates and Color value. As it's and "immediate GU", It refresh and refill the buffers every frames.

Here, I see two solution:
 - Non-OSG'ish: render the UI still using the GL function (glGen...) and shader
 - OSG version using geometries (created and destructed each frame)

What would be the recommended solution to integrate such library?


Thank you!
Florian
