class opengl.GLOrtho(GLViewport)

GLOrtho provides an OpenGL drawing area with an orthographic projection.

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

Constructor

GLOrtho(rect = None, xmin = -1, xmax = 1, ymin = -1, ymax = 1, near = -1, far = 1)
Creates a GLOrtho instance with the given initial values for its projection parameters.

Attributes

xmin, xmax, ymin, ymax, near, far
The projection parameters, as used by glOrtho(). You can change these to dynamically modify the projection.
