class opengl.GLPerspective(GLViewport)

GLPerspective provides an OpenGL drawing area with a perspective projection.

Using a GLPerspective widget is the same as using a GLViewport, except that you do not need to provide a setup_projection() method.

Constructor

GLPerspective(rect = None, fovy = 20, near = 0.1, far = 1000)
Creates a GLPerspective instance with the given initial values for its projection parameters.

Attributes

fovy, near, far
The projection parameters, as used by gluPerspective(). You can change these to dynamically modify the projection. The aspect ratio is calculated automatically from the widget dimensions.
