Sampling from a texture in OpenGL is black

由 眉间皱痕 提交于 2021-02-18 18:12:15
问题 I'm trying out my hand at graphics, following a tutorial at http://en.wikibooks.org/wiki/OpenGL_Programming/Modern_OpenGL_Tutorial_06 Problem: When I try to texture my cube, my sample is black. Screenshot: http://puu.sh/2JP1H.jpg (note: I set blue = uv.x to test my UVs) I looked at the threads OpenGL textures appear just black, and Texture is all black, but it seemed they had different problems. First I load my texture using SOIL image loading library: int w, h; unsigned char* img = SOIL_load

CreateDC() causes glutInit() to fail?

问题 I wrote a code that creates a window and draws a shape into it: #include<glew.h> #include<iostream> #include<GL\freeglut.h> #include<Windows.h> #include<stdlib.h> #include<math.h> #pragma once void Render_All() { glClear(GL_COLOR_BUFFER_BIT); glBegin(GL_POLYGON); glColor3f(1, 0, 0); glVertex2f(0.5, 0.5); glColor3f(1, 0, 0); glVertex2f(0.5, -0.5); glColor3f(1, 0, 0); glVertex2f(-0.5, -0.5); glColor3f(1, 0, 0); glVertex2f(-0.5, 0.5); glEnd(); glFlush(); } int main(int argc, char** argv) {

VS2010/VS2012/VS2015下openGL环境配置（转）

按：按照下述博文，三个例子均成功。 https://blog.csdn.net/so_geili/article/details/51685005 请仔细阅读每一个字。 为了学习《OpenGL超级宝典（第五版）》必须配置OpenGL环境，正所谓工欲善其事必先利其器。翻阅了很多网上的配置教程，很多都有问题，但也有详细的精华教程，比如博客： http://www.zyh1690.org/build-opengl-super-bible-fifth-edition-development-environment/ 。尽管该教程很详细，但其中还是有些细节问题，博客中没有细说。配置OpenGL环境一定要细心、耐心。因为有一点疏忽都可能导致最终配置环境失败。本篇虽然是针对“ win7 X64 +VS2010”环境的配置过程，但是我 在VS2012/VS2015下也搭建成功 了，VS2012/VS2015下配置OpenGL的原理也很简单，就是其中的Microsoft Visual Studio 10.0下要添加的文件变成Microsoft Visual Studio 12.0或 Microsoft Visual Studio 15.0下添加相关的文件。 配置环境： win7 X64 + Visua Studio 2010 win7 X64 + Visua Studio 2012 win7 X64
