I am trying to batch draw a bunch of circles using their vertices (using
below function to generate many circles) instead of using glVertex2f in a
loop to draw a circle.
class Snowflake(object):
def __init__(self, x, y, radius, d, batch):
self.x = x
self.y = y
self.r = radius
self.d = d
circle = self.create_vertices(x, y, self.r)
self.vertex_list = batch.add(len(circle[1])//2,
pyglet.gl.GL_POLYGON, None,
circle,('c4f',(1, 1, 1, 0.8)*(len(circle[1])//2)))
def create_vertices(self, x, y, radius, sides=24):
vertices = []
for i in range(sides):
angle = math.radians(float(i)/sides * 360.0)
x1 = radius*math.cos(angle) + x
y1 = radius*math.sin(angle) + y
vertices += [x1,y1]
return ('v2f', vertices)
However, upon doing this and running batch.draw(), it links each polygon
together from where the last vertice is in each vertex list to the start of
the next. Is it not possible to batch polygons and separate them like this
or is there something I am missing? Sorry if this is a stupid question.
Thanks for any help.
