[Dev-C++] Dynamic aspect ratio

[FerretallicA <fer...@ho...>]

Is there a 'proper' way to make an OpenGL app scale properly when you resize
it's host window to a different Height:Width ratio? I would have imagined it
would be as simple as the following line-

gluPerspective(45.0f,(GLfloat)(App.Window.Width /
App.Window.Height),0.1f,100.0f);

Instead it results in the scene scaling when resized vertically, and only
showing more or less of the scene when resized horizontally.

Hello!

Here's a shot... try this:

gluPerspective(45.0f,
	(GLfloat)App.Window.Width / App.Window.Height,
	0.1f, 100.0f);

Note the missing braces. This has probably to do with the order of
type-casting.
