另一个OpenGL SuperBible第5版设置问题

Another OpenGL SuperBible 5th edition set-up problems

本文关键字:设置 问题 5版 OpenGL SuperBible 另一个      更新时间:2023-10-16

好吧,我刚刚买了这本opengl超级软件书(第5版)。不幸的是,我在第一章中偶然发现了如何设置opengl本身。这是我做的步骤。

(1) 首先,我安装了Microsoft Visual Studio 2010 C++学习版

(2) 我下载了所需的库,为此我直接从opengl superible的官方网站下载:http://www.starstonesoftware.com/files/SB5.zip.然后我将这些文件提取到本地文件夹中。

(3) 然后我创建了一个新的空项目
文件->新建->项目->Visual C++安装的模板->常规->空项目

(4) 为freeglut和gltools文件头添加额外的includedirectories路径
项目->属性->配置属性->(然后我设置配置=所有配置)->C/C++->常规->其他包含目录
在这里我添加了两个目录:
(a) freeglut:[我的本地路径]\SB5\freeglut-2.60\include
(b) gltools:[我的本地路径]\SB5\Src\gltools\include

(5) 为freeglut和gltools文件头添加额外的依赖项路径
项目->属性->配置属性->(然后我设置配置=所有配置)->链接器->输入->其他依赖项
(a) freeglut_static.lib
(b) GLTools.lib

(6) 正在添加库目录
项目->属性->配置属性->(然后我设置配置=所有配置)->VC++目录->库目录。在这里,我设置了freeglut_static.lib和GLTools.lib的目录位置
(a) freeglut_static.lib:[my local path]\SB5\freeglut-2.60\VisualStudio2008Static\Release
(b) GLTools.lib:[my local path]\SB5\VisualStudio2008\GLTools\Release

(7) 之后,我复制了源代码(Triangle.cpp),但我没有忘记在第一行包含windows.h

// Triangle.cpp
// Our first OpenGL program that will just draw a triangle on the screen.
#include <Windows.h>
#include <GLTools.h>            // OpenGL toolkit
#include <GLShaderManager.h>    // Shader Manager Class
#ifdef __APPLE__
#include <glut/glut.h>          // OS X version of GLUT
#else
#define FREEGLUT_STATIC
#include <GL/glut.h>            // Windows FreeGlut equivalent
#endif
GLBatch triangleBatch;  
GLShaderManager shaderManager;
///////////////////////////////////////////////////////////////////////////////
// Window has changed size, or has just been created. In either case, we need
// to use the window dimensions to set the viewport and the projection matrix.
void ChangeSize(int w, int h)
{
    glViewport(0, 0, w, h);
}

///////////////////////////////////////////////////////////////////////////////
// This function does any needed initialization on the rendering context. 
// This is the first opportunity to do any OpenGL related tasks.
void SetupRC()
{
    // Blue background
    glClearColor(0.0f, 0.0f, 1.0f, 1.0f );
    shaderManager.InitializeStockShaders();
    // Load up a triangle
    GLfloat vVerts[] = { -0.5f, 0.0f, 0.0f, 
                          0.5f, 0.0f, 0.0f,
                          0.0f, 0.5f, 0.0f };
    triangleBatch.Begin(GL_TRIANGLES, 3);
    triangleBatch.CopyVertexData3f(vVerts);
    triangleBatch.End();
}

///////////////////////////////////////////////////////////////////////////////
// Called to draw scene
void RenderScene(void)
{
    // Clear the window with current clearing color
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT | GL_STENCIL_BUFFER_BIT);
    GLfloat vRed[] = { 1.0f, 0.0f, 0.0f, 1.0f };
    shaderManager.UseStockShader(GLT_SHADER_IDENTITY, vRed);
    triangleBatch.Draw();
    // Perform the buffer swap to display back buffer
    glutSwapBuffers();
}

///////////////////////////////////////////////////////////////////////////////
// Main entry point for GLUT based programs
int main(int argc, char* argv[])
{
    gltSetWorkingDirectory(argv[0]);
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGBA | GLUT_DEPTH | GLUT_STENCIL);
    glutInitWindowSize(800, 600);
    glutCreateWindow("Triangle");
    glutReshapeFunc(ChangeSize);
    glutDisplayFunc(RenderScene);
    GLenum err = glewInit();
    if (GLEW_OK != err) {
        fprintf(stderr, "GLEW Error: %sn", glewGetErrorString(err));
        return 1;
    }
    SetupRC();
    glutMainLoop();
    return 0;
}

(8) 在第7步之后,我构建了这个项目,一切仍然顺利。以下是构建结果:

========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========

(9) 我运行程序时出现了问题。我得到运行时错误。有一个警报对话框,显示以下消息:

Unhandled exception at 0x00000000 in superbible1.exe: 0xC0000005: Access violation reading location 0x00000000.

当我选择中断程序时,光标停在这一行:

   GLfloat vVerts[] = { -0.5f, 0.0f, 0.0f, 
                          0.5f, 0.0f, 0.0f,
                          0.0f, 0.5f, 0.0f };

如果我用另一个简单的代码(来自opengl红皮书)来更改这个代码。例如:

#define FREEGLUT_STATIC
#include <Windows.h>
#include <GLglut.h>
void display(void)
{
    /* clear window */
     glClear(GL_COLOR_BUFFER_BIT); 

    /* draw unit square polygon */
    glBegin(GL_POLYGON);
        glVertex2f(-0.5, -0.5);
        glVertex2f(-0.5, 0.5);
        glVertex2f(0.5, 0.5);
        glVertex2f(0.5, -0.5);
    glEnd();
    /* flush GL buffers */
    glFlush(); 
}

void init()
{
    /* set clear color to black */
    /*  glClearColor (0.0, 0.0, 0.0, 0.0); */
    /* set fill  color to white */
    /*  glColor3f(1.0, 1.0, 1.0); */
    /* set up standard orthogonal view with clipping */
    /* box as cube of side 2 centered at origin */
    /* This is default view and these statement could be removed */
    /* glMatrixMode (GL_PROJECTION);
    glLoadIdentity ();
    glOrtho(-1.0, 1.0, -1.0, 1.0, -1.0, 1.0);  */
}
int main(int argc, char** argv)
{
    /* Initialize mode and open a window in upper left corner of screen */
    /* Window title is name of program (arg[0]) */
    /* You must call glutInit before any other OpenGL/GLUT calls */
    glutInit(&argc,argv); 
    glutInitDisplayMode (GLUT_SINGLE | GLUT_RGB);  
    glutInitWindowSize(500,500);
    glutInitWindowPosition(0,0); 
    glutCreateWindow("simple"); 
    glutDisplayFunc(display);
    init();
    glutMainLoop();
}

该应用程序可以运行良好。所以我想可能是代码出了问题,或者可能是我错过了什么。所以有人可以帮忙吗?

我也刚刚开始这方面的工作。

如果你要学习所有的例子,最好将所有的freeglut/GLTools.h.lib文件复制到VC++2010的相关目录中。

您仍然需要在源代码中包含windows.h,并且仍然需要特别告诉VC++2010使用GLTools.lib(Linker,Input,Additional Dependencies)。

这个显然解释了如果pdb错误困扰你,如何消除它们。

GLfloat vVerts[] = { -0.5f, 0.0f, 0.0f, ...不会成为问题。但是Visual的绿色调试光标显示了将要执行的NEXT行,所以我怀疑它是shaderManager.InitializeStockShaders();崩溃了。

我不知道这是怎么回事,但它可能会读取文件。。。确保它能找到它们。特别是,根据zip的内容,从一个似乎有意义的目录直接从资源管理器运行.exe。
