Re: [PyOpenGL-Users] size limit of vertex array?

[Ian M. <geo...@gm...>]

My recommendation: use glDrawArrays(...).

#Init:
self.vertices = []
self.normals = []
self.nbrindices = 0
unit = 1.0
y = 0.0
rows = 2
columns = 8
z_center_delta = unit * (float(rows) / 2.0)
x_center_delta = unit * (float(columns) / 2.0)
for i in range(rows):
    delta_z = (unit * float(i)) - z_center_delta
    for j in range(columns):
        delta_x = (unit * float(j)) - x_center_delta
        self.vertices += [[0.0 + delta_x, y, 0.0 + delta_z],
                          [0.0 + delta_x, y, unit + delta_z],
                          [unit + delta_x, y, unit + delta_z],
                          [unit + delta_x, y, 0.0 + delta_z]]
        self.normals += [[0.0, +1.0, 0.0],
                         [0.0, +1.0, 0.0],
                         [0.0, +1.0, 0.0],
                         [0.0, +1.0, 0.0]]

#Draw:
glPolygonMode(GL_FRONT_AND_BACK,GL_LINE)

glEnableClientState(GL_VERTEX_ARRAY)
glEnableClientState(GL_NORMAL_ARRAY)

glVertexPointer(3, GL_FLOAT, 0, self.vertices) # Specify the vertex list to
be used to draw the object
glNormalPointer(GL_FLOAT, 0, self.normals) # Specify the normals list to be
used to draw the object

glDrawArrays(GL_QUADS,0,len(self.vertices))

glDisableClientState(GL_VERTEX_ARRAY)
glDisableClientState(GL_NORMAL_ARRAY)
