Custom renderer: missing vertices

For help with anything that CEGUI doesn't offer straight out-of-the-box, e.g.:
- Implementation of new features, such as new Core classes, widgets, WindowRenderers, etc. ...
- Modification of any existing features for specific purposes
- Integration of CEGUI in new engines or frameworks and writing of new plugins (Renderer, Parser, ...) or modules

Custom renderer: missing vertices

Postby manhnt » Tue Jul 02, 2019 07:47

In my renderer (https://bitbucket.org/manhnt9/cegui/branch/saga), I notice that my geometry buffer filling is not complete.
The only correct geometry buffer is the CEGUI logo.

Here is what I see on the screen and the logo render call.

OpenGL3 render calls for reference.

The first draw call should have 108 vertices.
But mine only have 12.

Here is my Geometry Buffer code: https://bitbucket.org/manhnt9/cegui/src ... Buffer.cpp
Could you give me some suggestions for further investigation?

How do you know it is not complete?

Have you built a minimal repro case of just one image or text only widget and stepped through code to see what happens with the geom?

Here I wrote a custom renderer for my engine and it works. You may have a look and compare it with yours. I wrote mine with a DX11 renderer as a reference, but there must be a little difference.

I can see draw calls and buffer in RenderDoc and see that it doesn't have a complete geometry (less vertices than OpenGL's draw call).
And thanks for the great idea, I should and will write a minimal app. Was trying to fix a complex samples framework ever since.

Thank you, I'll take a look!
