Wireframe / Texture hybrid option

Wireframes are very educational, but at the same time they can be very disorienting. Would it be possible to have wireframe enabled while textures are still enabled? For contrast the color of the wireframe could continuously cycle through the entire color wheel to ensure at least some of time it contrasts with the surrounding texture.

Alternatively the terrain could be plain colored instead of textured with constant colored contrasting wireframes. Perhaps the plain color could be the color average of the texture, assuming that’s easy to obtain.

It may not work perfectly (such as some dashed lines) https://www.opengl.org/discussion_boards/showthread.php/127465-Dash-line-in-wireframe-after-fill-polygon

However I think it would still be a great aid in making sense of the wireframe meshes which don’t hide meshes that are behind other meshes resulting in a jumbled mess from many vantage points. In the hybrid model the wireframe would be the first pass, then filled polygons on the second pass covering wireframes that are behind them.

The current wireframe still uses the texture color so I imagine you mean draw the regular terrain and overlay the wireframe. This is a feature we would have to add, but, yes, it could be done.

Somewhat related, you can see the imagery tiling by selecting “Grid” here: https://cesiumjs.org/Cesium/Apps/Sandcastle/index.html?src=Imagery%20Layers%20Manipulation.html&label=Showcases


I did notice that the wireframes did seem to have the terrain color, but the lines are so thin it’s difficult to notice. It would be nice if the polygon fill-in color were to use this color, if this feature were to ever be implemented.

The lat/lon grid lines feature would be great with numbers attached as well. I assume the latitude lines are spaced ‘geodetically’ rather than ‘geocentrically’.
