问题描述
我无法使用Derelict3和GLFW 3使OpenGL 3.2在Lion(osx 10.7.4)上运行.
I'm having trouble getting OpenGL 3.2 to run on Lion (osx 10.7.4) using Derelict3 and GLFW 3.
这是我的测试程序:
module glfw3Test;
import std.stdio, std.conv;
import derelict.glfw3.glfw3;
import derelict.opengl3.gl3;
string programName = "glfw3Test";
int width = 640;
int height = 480;
GLFWwindow window;
void main() {
// load opengl
DerelictGL3.load();
// load GLFW
DerelictGLFW3.load();
if(!glfwInit()) {
glfwTerminate();
throw new Exception("Failed to create glcontext");
}
writefln("GLFW: %s", to!string(glfwGetVersionString()));
window = glfwOpenWindow(width, height, GLFW_WINDOWED, programName.ptr, null);
if(!window) {
glfwTerminate();
throw new Exception("Failed to create window");
}
// Request opengl 3.2 context
// based off the GLFW FAQ: http://www.glfw.org/faq.html#4_2
glfwOpenWindowHint(GLFW_OPENGL_VERSION_MAJOR, 3);
glfwOpenWindowHint(GLFW_OPENGL_VERSION_MINOR, 2);
glfwOpenWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
glfwOpenWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
DerelictGL3.reload();
// Print OpenGL and GLSL version
writefln("Vendor: %s", to!string(glGetString(GL_VENDOR)));
writefln("Renderer: %s", to!string(glGetString(GL_RENDERER)));
writefln("Version: %s", to!string(glGetString(GL_VERSION)));
writefln("GLSL: %s\n", to!string(glGetString(GL_SHADING_LANGUAGE_VERSION)));
}
我得到以下输出:
GLFW: 3.0.0 dynamic
Vendor: NVIDIA Corporation
Renderer: NVIDIA GeForce 9400M OpenGL Engine
Version: 2.1 NVIDIA-7.18.18
GLSL: 1.20
我已经检查过,看来我的图形卡应该最多支持OpenGL 3.3 .
I've checked, and it seems my graphics card should support up to OpenGL 3.3.
推荐答案
我要做的就是在 调用glfwOpenWindow
之前指定一些窗口提示:
All I had to do was specify some window hints before calling glfwOpenWindow
:
...
glfwOpenWindowHint(GLFW_OPENGL_VERSION_MAJOR, 3);
glfwOpenWindowHint(GLFW_OPENGL_VERSION_MINOR, 2);
glfwOpenWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
glfwOpenWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
window = glfwOpenWindow(width, height, GLFW_WINDOWED, programName.ptr, null);
...
