24 bit depth format Feature request

[Mandelbrow]

Is it possible to change the format of the depth buffer from what I believe is 16 bit to 24, or 32 bit for the rendering in the Cardboard SDK? Or make it an option to choose the size of the buffer for a project?

As for now meshes have a tendency to look wobbly when viewed at some distance.

Thanks @Mandelbrow for reaching out to us!

To track the possibility of having a way to modify the size of the depth buffer, an internal ticket has been created and will be prioritized along with other tickets in the backlog.

In the meantime, if you want to try this on your side, here is where the depth buffer size is set:

glRenderbufferStorage(GL_RENDERBUFFER, GL_DEPTH_COMPONENT16,
                          screen_width / 2, screen_height);

You can change GL_DEPTH_COMPONENT16 with another value.

After that is done, will need to follow the instructions in generate_gfx_plugin_cardboard_aar.md to generate a new aar file and add it to your project.

Bear in mind that we haven’t tested the library with different depth buffer sizes and issues may appear.

Feel free to ask any other question you might have about this topic.
Thanks!
