Synchronous Redraw?

[Fodderine]

It's me again

I can't figure out how to perform a synchronous redraw (i.e. finish opengl render before proceeding) inside a plugin.

Is it also possible to perform a openGL "grabScreen()" at a custom resolution?

self.app.redrawNow()

self.app.scene3d.grabScreen(x, y, width, height, os.path.join(grabPath, 'grab.bmp'))

Thanks Marc. redrawNow(); works great

The intent of the grab screen was to get a higher resolution output from openGL.
Say my window was running at 800x600, I want to obtain an output around 2400x1800 px.
I have worked around this before by specifying in C code to launch at a huge resolution, but this seemed like a dumb way of doing it .
Could I send a "resize event" programmatically so that makeHuman is only enlarged when I need to capture the output? Or is there an even easier way of doing this.

I guess in windows you can just call SetWindowPos with the hwnd of the makehuman window. You can get the hwnd by caption ("MakeHuman - [Untitled]" if not loaded or saved) or class ("SDL_app") or just take the first (and only) hwnd of the process.

Rendering to frame buffer (fbo) is planned, though not supported yet, so you can only get what's on the screen.
