我开始在 Qt 和着色器中使用 OpenGL(我有 OpenGL 经验，但还没有使用着色器)
I'm starting out on using OpenGL with Qt, and with Shaders (I have OpenGL experience, but not with shaders yet)
我正在学习本教程:http://releases.qt-project.org/learning/developerguides/qtopengltutorial/OpenGLTutorial.pdf(Qt5 OpenGL 官方教程).
I'm following this tutorial: http://releases.qt-project.org/learning/developerguides/qtopengltutorial/OpenGLTutorial.pdf (the official Qt5 OpenGL tutorial).
问题是，当我尝试运行我的程序时，出现黑屏并显示以下错误消息:
The problem is, that when I try to run my program, I get a black screen and the following error messages:
QGLShader::compile(Vertex): ERROR: 0:1: '' : version '130' is not supported
QGLShader::compile(Fragment): ERROR: 0:1: '' : version '130' is not supported
我的程序基于 QGLWidget
My program is based on a QGLWidget
通过在互联网上的一些浏览，我发现我需要使用 OpenGL 3.2 上下文，但 Qt 喜欢使用 OpenGL 2.x
With some browsing on the interwebs I found out that I need to use an OpenGL 3.2 context, but that Qt likes to use OpenGL 2.x
我的电脑:
那么，我怎样才能做到这一点?
So, how can I make this work?
我的版本是 3.2(通过 QGLFormat 设置)，没有指定格式它使用 2.0
My version is 3.2 (set through QGLFormat), without a specified format it uses 2.0
fragmentShader.frag:
fragmentShader.frag:
#version 130
uniform vec4 color;
out vec4 fragColor;
void main(void)
{
fragColor = color;
}
vertexShader.vert:
vertexShader.vert:
#version 130
uniform mat4 mvpMatrix;
in vec4 vertex;
void main(void)
{
gl_Position = mvpMatrix * vertex;
}
错误(格式，OpenGL 3.2):
Errors (with format, OpenGL 3.2):
QGLShaderProgram: shader programs are not supported
QGLShaderProgram::uniformLocation( mvpMatrix ): shader program is not linked
The program has unexpectedly finished.
错误(无格式，OpenGL 2.0):
Errors (without format, OpenGL 2.0):
QGLShader::compile(Vertex): ERROR: 0:1: '' : version '130' is not supported
QGLShader::compile(Fragment): ERROR: 0:1: '' : version '130' is not supported
较新的 QOpenGLWidget 不支持任何带有 QGLFormat 的构造函数.相反，在您的 main.cpp 中，为所有 QOpenGLWidget 和 QOpenGLContext 指定默认的 QSurfaceFormat 如下:
Newer QOpenGLWidget doesn't support any constructor with QGLFormat. Instead, in your main.cpp, specify the default QSurfaceFormat for all QOpenGLWidget and QOpenGLContext as following:
// main.cpp
QSurfaceFormat glFormat;
glFormat.setVersion(3, 3);
glFormat.setProfile(QSurfaceFormat::CoreProfile);
QSurfaceFormat::setDefaultFormat(glFormat);
现在你应该可以在你的着色器中使用类似 #version 330 core 的东西了.
Now you should be able to use something like #version 330 core in your shader.
