2D overly example #63

Closed shujaatak closed 4 years ago

shujaatak commented 4 years ago

Is there any 2D overly example? I want to draw menus over a 3D scene.

We don't have one yet.

I haven't tried this usage case yet. First thought is to take a similar approach to the vsgrendertexture example and utilize a CommanGraph+RenderGraph for the 3D scene and a CommandGraph+RenderGraph for the 2D scene. I guess one would also need to look at using a custom RenderPass to have the two passes work together.

I will try the suggested approaches although, for me, it would be difficult to implement as I am new to VSG. However, it would be highly useful to have one such example in vsgExamples.

By the way, I love VSG!

I got amazed when I saw your this VulkanSceneGraph Database Pager developments demo, I wonder from where I can download the test database so that I may run that demo on my machine.

The database isn't publicly available.

It would be nice to collect together high res DEM and Imagery that is published under a fully open license so we can generate a paged database that could be freely shared. My focus isn't on this side, it's on developing the software rather than creating demo databases etc.
