glsl pyOpenGL array passing

由 こ雲淡風輕ζ 提交于 2020-05-15 07:13:11
问题 I'm currently playing around with glsl. For that purpose i need to pass an array from the opengl code to the gsls, which then in return calculates a new color out of the array. But somehow this doesn't work for me. Instead of getting the whole array I'm always stuck with only the first entry. Could you help me by saying what I'm doing wrong? import numpy as np \\... array = np.array([1.2,2.5,3.8,4.3,5.6, #....]) location = glGetUniformLocation(program,"arrayInShader") glUniform1fv(location,1

【windows 安装Python】 因为在安装时，会提醒同步配置环境变量。因此按照步骤安装即可。 什么是Python？ Python是一种跨平台的计算机程序设计语言，是一个高层次的结合了解、编译、互动和面向对象的脚本语言。 最初是用于编写shell脚本，现在功能是越来越强大了。 Python是怎么执行的？ Python在执行时，首先会将.py文件中的源代码编译成Python的bytecode字节码，然后再由Python虚拟机来执行这些编译好的byte code。好像与Java呀，.NET类似哈。 Python虚拟机与他们不同的是，Python虚拟机是一种更高级的虚拟机，它是一种抽象层次更高的虚拟机。 Python可以以交互模式运行，比如主流操作系统Unix/Linux、Mac、Windows都可以通过交互模式运行。。 Python基本应用 1、图形处理：有PIL、Tkinter等图形库支持，能方便进行图形处理。 2、数学处理：NumPy扩展提供大量与许多标准数学库的接口。 3、文本处理：python提供的re模块能支持正则表达式，还提供SGML，XML分析模块，许多程序员利用python进行XML程序的开发。 4、数据库编程：程序员可通过遵循Python DB-API（数据库应用程序编程接口）规范的模块与Microsoft SQL Server，Oracle，Sybase，DB2

How to correctly add a light to make object get a better view with pygame and pyopengl

由 不打扰是莪最后的温柔 提交于 2020-04-14 07:38:12
问题 I am following the tutorial available in https://pythonprogramming.net/opengl-pyopengl-python-pygame-tutorial/ where he teachs how to render a cube with pyOpenGL an pygame. When rendering the cube, the tutorial set color to all the vertices of the cubes and then dispays it. However, im my project, i load object from a .obj file using the code provided in https://www.pygame.org/wiki/OBJFileLoader and most of my objects is fully white. Conclusion: when i render it on screen, i only see full

Need to Install PyOpenGL (Windows)

由 自古美人都是妖i 提交于 2020-03-16 08:42:09
问题 I am trying to install PyOpenGL using pip on Windows 10. I have tried to install it using pip install PyOpenGL and it tells me that it has installed it successfully but when I try to use PyOpenGL in python, it tells me that I do not have a module named PyOpenGL. Do you know what the problem is? 回答1: Go to Unofficial Windows Binaries for Python Extension Packages Download a 32 bit or 64 bit package for PyOpenGL provides bindings to OpenGL, GLUT, and GLE (e.g. PyOpenGL-3.1.5-cp38-cp38-win_amd64

How to rotate slices of a Rubik's Cube in python PyOpenGL?

由 房东的猫 提交于 2020-01-10 05:47:06
问题 I'm attempting to create a Rubik's Cube in Python, i have gotten as far as visually representing the cube. Struggling a bit with how to implement rotation. I guess i'm asking for feedback as to how to go about doing this. I thought at first of, rotating each cubes set of vertices's, without much luck. I basically want to select a slice from an array of cube objects (of varying size), perform a rotation and a translation on each object. import pygame import random from pygame.locals import *

.OFF files on Python

问题 I've been practicing with Python and PyOpenGL, but I can't seem to open .OFF files (Object File Format) with Python. If you're wondering, .OFF files are files that contain positions of a 3D object.

问题 Ok so I'm still struggling to get this to work. The important parts of my code are: def __init__(self, vertices, normals, triangles): self.bufferVertices = glGenBuffersARB(1) glBindBufferARB(GL_ARRAY_BUFFER_ARB, self.bufferVertices) glBufferDataARB(GL_ARRAY_BUFFER_ARB, ADT.arrayByteCount(vertices), ADT.voidDataPointer(vertices), GL_STATIC_DRAW_ARB) self.vertices = vertices self.bufferNormals = glGenBuffersARB(1) glBindBufferARB(GL_ARRAY_BUFFER_ARB, self.bufferNormals) glBufferDataARB(GL_ARRAY
