glOrtho

multiply the current matrix with an orthographic matrix

Signature

glOrtho( GLdouble ( left ) , GLdouble ( right ) , GLdouble ( bottom ) , GLdouble ( top ) , GLdouble ( nearVal ) , GLdouble ( farVal ) )-> void
glOrtho( left , right , bottom , top , zNear , zFar )

Parameters

VariablesDescription
left, right
Specify the coordinates for the left and right vertical clipping planes.
bottom, top
Specify the coordinates for the bottom and top horizontal clipping planes.
nearVal, farVal
Specify the distances to the nearer and farther depth clipping planes. These values are negative if the plane is to be behind the viewer.
