[英]openGL(pyglet) 3d scene not rendering properly on AMD Graphics card
[英]Pyglet not running properly on AMD HD4250
我正在使用pyglet构建python程序。 源代码可以在我的笔记本电脑以外的任何计算机上正常运行。 我的笔记本电脑也是唯一一款带有AMD显卡的笔记本电脑:HD4250。 它的Xubuntu 13.04 AMD64和图形驱动程序是X11开源的。 它是这样的:
在构造函数中添加一条清晰的语句时,屏幕会正确构建,但是速度却非常慢。 每30秒最多刷新2次,几乎不响应任何输入。 我怎样才能解决这个问题?
似乎OpenGL并不是问题所在:使用Qt OpenGL(也为C ++)时,根本没有这样的问题。
一些(希望是相关的)代码:
def draw(self):
pyglet.text.Label('Start Screen',
font_name='Arial',
font_size=16,
x=self.window.get_size()[0]/2, y=self.window.get_size()[1]-20,
anchor_x='center', anchor_y='center').draw()
pyglet.text.Label('This side is looking at the enemy',
font_name='Arial',
font_size=16,
x=self.window.get_size()[0]/2, y=self.window.get_size()[1]-60,
anchor_x='center', anchor_y='center').draw()
pyglet.text.Label(self.bottumText,
font_name='Arial',
font_size=16,
x=self.window.get_size()[0]/2, y=20,
anchor_x='center', anchor_y='center').draw()
for y in range(0, len(self.fields)):
for field in self.fields[y]:
if (field.selected):
glColor3f(self.color[0], self.color[1], self.color[2])
# glColor3f(1, 0, 1)
else:
glColor3f(1, 1, 1)
# Draw center
# self.drawCircle(field.x, field.y, 5, [1, 1, 1])
# # Draw top side
pyglet.graphics.draw(2, pyglet.gl.GL_LINES, ('v2i',
(field.x + field.size, field.y + field.size,
field.x - field.size, field.y + field.size)))
# Draw down side
pyglet.graphics.draw(2, pyglet.gl.GL_LINES, ('v2i',
(field.x + field.size, field.y - field.size,
field.x - field.size, field.y - field.size)))
# Draw left side
pyglet.graphics.draw(2, pyglet.gl.GL_LINES, ('v2i',
(field.x - field.size, field.y - field.size,
field.x - field.size, field.y + field.size)))
# Draw right side
pyglet.graphics.draw(2, pyglet.gl.GL_LINES, ('v2i',
(field.x + field.size, field.y - field.size,
field.x + field.size, field.y + field.size)))
以下代码产生什么:
(它本身不限于特定的帧缓冲区,因此可能会产生更好的输出)
#!/usr/bin/python
import pyglet
from time import time, sleep
class Window(pyglet.window.Window):
def __init__(self, refreshrate):
super(Window, self).__init__(vsync = False)
self.frames = 0
self.framerate = pyglet.text.Label(text='Unknown', font_name='Verdana', font_size=8, x=10, y=10, color=(255,255,255,255))
self.last = time()
self.alive = 1
self.refreshrate = refreshrate
self.click = None
self.drag = False
def on_draw(self):
self.render()
def on_mouse_press(self, x, y, button, modifiers):
self.click = x,y
def on_mouse_drag(self, x, y, dx, dy, buttons, modifiers):
if self.click:
self.drag = True
print 'Drag offset:',(dx,dy)
def on_mouse_release(self, x, y, button, modifiers):
if not self.drag and self.click:
print 'You clicked here', self.click, 'Relese point:',(x,y)
else:
print 'You draged from', self.click, 'to:',(x,y)
self.click = None
self.drag = False
def render(self):
self.clear()
if time() - self.last >= 1:
self.framerate.text = str(self.frames)
self.frames = 0
self.last = time()
else:
self.frames += 1
self.framerate.draw()
self.flip()
def on_close(self):
self.alive = 0
def run(self):
while self.alive:
self.render()
# ----> Note: <----
# Without self.dispatc_events() the screen will freeze
# due to the fact that i don't call pyglet.app.run(),
# because i like to have the control when and what locks
# the application, since pyglet.app.run() is a locking call.
event = self.dispatch_events()
sleep(1.0/self.refreshrate)
win = Window(23) # set the fps
win.run()
您可以尝试强制使用您正在使用的开放驱动程序的特定绘图方法,例如:
glEnable(GL_TEXTURE_2D)
和
glClear(GL_COLOR_BUFFER_BIT)
glLoadIdentity()
glBegin(GL_TRIANGLES)
glVertex2f(0, 0)
glVertex2f(window.width, 0)
glVertex2f(window.width, window.height)
glEnd()
