pyopengl

问题 I am making a game using OpenGL with Pygame. So far I was able to make cubes appear and make a cross hair. When I tried to implement looking around, things got... weird. I would run it and without even moving my mouse it would start spinning the screen everywhere when I used the gluLookAt() function. When I took that out, it worked but I couldn't look around. I was doing some testing and I even put in set data values to the function just to make sure that they were not changing and it still

问题 I am following a tutorial series that is rather old on pyOpenGL and I am doing exactly as he does. However I am experiencing lag - I have AMD FX-6300 with 8gb ram, GTX-1050ti and files are stored on a flashdrive. I have read some places that using glBegin and glEnd cause issues? What should I use instead and how would I do it in this code: import pygame from pygame.locals import * from OpenGL.GL import * from OpenGL.GLU import * import random """ - A Cube has 8 Nodes/Verticies - 12 Lines

问题 I am using OpenGL to render a scene in python. My code works perfectly fine on windows but, for some reason, I'm having issues when importing opengl.gl on MacOS. The issue arises when calling from OpenGL.GL import ... in both python scripts and the python console. More specifically here is the exact call in my script: from OpenGL.GL import glGenBuffers, glBindBuffer, glBufferData, \ glGenVertexArrays, glBindVertexArray, glEnableVertexAttribArray, glVertexAttribPointer, \ glDrawArrays,

问题 I am making a game (RPG) in PyOpenGL which I have a crosshair. I want to check if a 3d object is in the crosshair (or detect if it is at a point), which is a 2d overlay. How can I do that? I tried to use screen.get_at() function, but it displays an error "Cannot call on OpenGL surfaces". Also, it is not good because it only detects a colour, not an object (although you can use the colour to determine an object, but what if there are several objects that have the same colour?). This is what I

问题 I decided to try using OpenGL VBO in Python to improve FPS. I found code, that worked perfectly fine in Linux OS (Ubuntu), but when I tried launching in Windows OS, the code resulted in a message: "GLUT Display callback with (),{} failed: returning None module 'numpy' has no attribute 'float128'" So, I can't run the code specifically on Windows, but because I want to create a cross-platform application, I really need to solve this. I've done a lot of research and only found that numpy

问题 I've written a code to draw a line. Here is the function: def drawLines(): r,g,b = 255,30,20 #drawing visible axis glClear(GL_COLOR_BUFFER_BIT) glColor3ub(r,g,b) glBegin(GL_LINES) #glRotate(10,500,-500,0) glVertex2f(0,500) glVertex2f(0,-500) glEnd() glFlush() Now I'm trying to rotate the line. I'm trying to follow this documentation but can't understand. According to the documentation the rotating function is defined as follows: def glRotate( angle , x , y , z ): I've no z-axis. So I'm
