Hey,
it is not against you but it is funny if somebody write about a problem and get answers like
"why would you do this" or "can you do it a different way"? Belive me that i have my reasons.
I never wrote that i code a game
I want to interactively place positions on the groundview.
This also means that i have to place corners of a polygon that will be tesselated afterwards.
In perspective projection a high geometry (a building) would be an obstacle to parts of the
ground. Only in orthographic Projection i do not have this.
It could be an alternative to use a small fov and a far distance. This would be a compromise
not a solution. I do not see the reason why it should be forbidden to the the projection matrix.
This would be a basic feature to create modelling tolls and authoring systems as well. Show me
a 3D Modelling Application that does not support orthographic rendering and let me consider a
Gameeditor as some kind of modelling App.
