ortho

Description:

public void ortho (float left, float right, float bottom, float top, float near, float far)

Replaces the current projection matrix with an orthographic projection matrix.

Note:

Use cogl_framebuffer_orthographic instead

See cogl-ortho-matrix to see how the matrix is calculated.

Note:

This function copies the arguments from OpenGL's glOrtho even though they are unnecessarily confusing due to the z near and z far arguments actually being a "distance" from the origin, where negative values are behind the viewer, instead of coordinates for the z clipping planes which would have been consistent with the left, right bottom and top arguments.

Parameters:

left	The coordinate for the left clipping plane
right	The coordinate for the right clipping plane
bottom	The coordinate for the bottom clipping plane
top	The coordinate for the top clipping plane
near	The `distance` to the near clipping plane (negative if the plane is behind the viewer)
far	The `distance` for the far clipping plane (negative if the plane is behind the viewer)
