pyglet

I have a problem that when playing a video with pyglet apparently the beginning and the end of the stream is not handled correctly. The player ignores the first keyframe and thus shows glitches images until the it finds the second keyframe. Likewise the on_eos-event is not fire but python chrashes because it apparently tries to load more frames. import pyglet vidPath = "test.mp4" window = pyglet.window.Window() player = pyglet.media.Player() source = pyglet.media.load(vidPath) player.queue(source) player.play() @player.event def on_eos(): print('video end') @window.event def on_draw(): window

continuing on from my explorations of the basics of OpenGL (see this question ), I'm trying to figure out the basic principles of drawing a scene with OpenGL. I am trying to render a simple cube repeated n times in every direction. My method appears to yield terrible performance : 1000 cubes brings performance below 50fps (on a QuadroFX 1800, roughly a GeForce 9600GT). My method for drawing these cubes is as follows: done once: set up a vertex buffer and array buffer containing my cube vertices in model space set up an array buffer indexing the cube for drawing as 12 triangles done for each

I'm trying to pick a 3d point. I read various sites but my code doesn't work. on right mouse click: glGetFloatv(GL_MODELVIEW_MATRIX,mv_mat) glGetFloatv(GL_PROJECTION_MATRIX,p_mat) ip_mat = np.linalg.inv(mat4(p_mat)) # clip = array[ # (2*x)/window_width-1 # 1-(y*2)/window.height # -1 # 1 camera_coord = np.dot(ip_mat,clip) camera_coord = np.array([camera_coord[0,0],camera_coord[0,1],-1,0]) imv_mat = np.linalg.inv(mat4(mv_mat)) ray_world = np.dot(imv_mat,camera_coord) ray_world = np.array([ray_world[0],ray_world[1],ray_world[2]]) ray_world = ray_world/np.linalg.norm(ray_world) Intersect_sphere

I have a label matrix with dimension (100*100), stored as a numpy array, and I would like to display the matrix with pyglet. My original idea is to use this matrix to form a new pyglet image using function pyglet.image.ImageData(). It requres a buffer of the imagedata as an input, however I have no idea how to get a right formated buffer from the numpy array. Any one have any idea? ps. my current solution: 3d_label = numpy.empty([100,100,3]) 3d_label[:,:,0] = label * 255 # value range of label is [0,1] 3d_label[:,:,1] = label * 255 3d_label[:,:,2] = label * 255 image_data = ctypes.string_at(id
