grid

Draw a grid.

This function draws a grid with its corner and the origin (0,0,0) extending in the positive x and y-directions. The center of the grid is at the point (x/2, y/2).

To draw a grid centered at the origin use the batch rendering method at.

syntax

grid(x, y, nx, ny)

parameters

x	length of the grid in the x-direction
y	length of the grid in the y-direction
nx	number of cells in the x-direction
ny	number of cells in the y-direction

examples

draw a grid in the x-y plane

def display():
   lighting(False)
   grid(20, 20, 10, 10)

draw a grid in the x-z plane

def display():
   lighting(False)
   pushMatrix()
   rotateX(90)
   grid(20, 20, 10, 10)
   popMatrix()

draw a grid in the y-z plane

def display():
   lighting(False)
   pushMatrix()
   rotateY(90)
   grid(20, 20, 10, 10)
   popMatrix()

draw a grid centered at the origin

def display():
   lighting(False)
   size=20
   draw(grid, size, size, 10, 10).at([-size/2, -size/2, 0])
