Re: [pygame] New way for drawing an arc
The presented code definitely has room for a lot of optimization. My solution for drawing arcs was to either render it with two circles to a surface, and then crop/cut it out, or to just use OpenGL. The idea would be to use many small subdivisions just as with the polygon drawing method for PyGame. I suppose the absolute fastest thing to do (short of just doing it in your favorite paint program and just drawing it as an image) would be to write a fragment program and run it on the GPU. 'Course, that's overkill . . . right? Ian
Re: [pygame] cx_Freeze and Pygame Font module
Ok so I want to create an executable but one of my files is basically import game and then game.play(). Can I execute the file that has like 2 lines or should I put everything into one file and build and execute that. Btw I'm on a Mac with python 2.7 do which 'compiler' should I use? The Build Applet tool that comes with it doesn't seem to work -Zack On Jan 5, 2012, at 7:31 PM, Lenard Lindstrom wrote: > Hi, > > On 05/01/12 02:16 PM, Nick Arnoeyts wrote: >> Hey everyone >> >> I'm trying to get to know cx_freeze as an alternative to py2exe but I've run >> into some problems.

Re: [pygame] New way for drawing an arc
Just worked on trying to use AA. turns out the way I'm checking locations, pixel-to-pixel, very few locations actually get caught by my secondary checks. The effect is pretty much invisible. Another way to do an arc would be to calculate the minimum outer circle width between points, using a combination of the pythagorean theorem and trigonometry, but I won't do it now. Maybe in the future.

This function in C should run at the speed the current rotation function runs :). Polygons.. Say, you could use an altered version of my function to calculate the exact accuracy of polygon you'd need to get full reproduction. Maybe you could use this idea?
Re: [pygame] New way for drawing an arc
Cool! When I needed to draw an arc more than a couple of pixels wide, I approximated it with a polygon. I think it gave pretty good results. I'm not sure how it would compare performance-wise, but it should involve a lot fewer trig function calls. Have you tried this method? -Christopher On Thu, Jan 5, 2012 at 6:36 PM, Silver wrote: > I recently figured out how to draw an arc in pygame without moire holes > and allowing stuff like antialiasing.

[pygame] New way for drawing an arc
I recently figured out how to draw an arc in pygame without moire holes and allowing stuff like antialiasing. Just if any of your are interested. The script is a little slow. Also: atan issues where the arc starts out from the left instead of top. I can't seem to fix it. --Rockachu2 import math def draw_arc_matrix(matrix, pos, radius, color, width, angle1, angle2): #print "Drawing arc at", pos, "with radius of ", radius for x in xrange(getmatrixwidth(matrix)): for y in xrange(getmatrixheight(matrix)): n = ((x-pos[0])**2 )+ ((y-pos[1])**2 ) if n > (radius-width)**2: if n < (radius)**2: ## now to check arc #print x,y #setpoint(matrix, [x,y], color) angle = math.atan2(y-pos[1], x-pos[0]) angle = math.degrees(angle)+180 #print angle, angle1, angle2 if angle1 > angle2: if angle < angle1: if angle > angle2: setpoint(matrix, [x,y], color) #print x,y else: if angle > angle1: if angle < angle2: #print x,y setpoint(matrix, [x,y], color) def setpoint(matrix, pos, color): matrix.set_at(pos, color) #matrix[pos[0]][pos[1]] = color #return matrix def getmatrixwidth(matrix): # reurn len(matrix) return matrix.get_rect().width def getmatrixheight(matrix): # return len(matrix[0]) return matrix.get_rect().height if __name__ == "__main__": import pygame pygame.init() screen = pygame.display.set_mode((200,200)) angle = 0 anglec = 1 while True: anglec += .1 anglec %= 360 screen.fill((0,0,0)) draw_arc_matrix(screen, (100,100), 80, (255,255,255), 10, angle, anglec) pygame.display.update() pygame.event.get()
[pygame] cx_Freeze and Pygame Font module
Hey everyone I'm trying to get to know cx_freeze as an alternative to py2exe but I've run into some problems. There don't seem to be any errors in creating the exe, however when running the exe there are complaints about missing modules and DLL Load Errors (see below for the error message). I am using Python 2.7 (32-bit) on Windows 7 SP1 (64-bit). Tell me if there is anything else I have to post and I will do my best.
