As of 0.9.6, GLM uses radians instead of degrees. Change all calls to GLM that use degrees.

glm (at least version 0.9.9.8) is header-only library and you don't need to link it.

This line should be removed

The smoke example fails to work on Intel cards. Seems to be related to use of GL_PROGRAM_POINT_SIZE.

CMake Error in ingredients/CMakeLists.txt:

Hello

Hello does any one what this means.

genType glm::inversesqrt(const genType&) [with genType = float]: Assertion `x > genType(0)' failed.

Hi!

    gl_TessLevelOuter[0] = float(NumSegments);
    gl_TessLevelOuter[1] = float(NumStrips);

should be:

    gl_TessLevelOuter[0] = float(NumStrips);
    gl_TessLevelOuter[1] = float(NumSegments);

Best regards!

I own your book and don't get (or cannot find explanation in book) why glDeleteVertexArrays and glDeleteBuffers are not used in the source code?

Not sure if the git still being maintained. When I open GLSLCOOKBOOK.sln, and right click on ALL_BUILD and build, I keep receiving
LINK : fatal error LNK1104: cannot open file '..\ingredients\Debug\ingredients.lib'
and I didn't have this 'ingredients.lib' in the specified location. Any idea?
I am using visual studio 2015 with CMake 3.50

should Forward Compatible Context flag be really used?

I've found this answer at StackExchange and it says:

Never, ever, ever, EVER use FORWARD_COMPATIBLE for ANYTHING.

So maybe this line from main.cpp

    glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);

should be simply removed?

Hello I am stuck on step 10) of "Compiling for Windows with Visual Studio 2012". Specifically when I press configure on CMake, it can find the GLFW3_INCLUDE_DIR but cannot find GLFW3_LIBRARY. If it helps, cmake can find GLM_INCLUDE_DIR. I have placed all the files in "ProgramFiles(x86)" as stated in the instructions.

Hello, I encountered several errors after building the code. I used CodeBlocks 13.12 + GCC 4.8 on Linux for reference. The first error was that "stdio.h" or "cstdio" had not been declared in any of the main.cpp for all chapters -- so I just added the include and that resolved the error there. The second error I encountered involves Chapter 5 for both the 'blur' and 'oit' recipes. For 'oit' I receive a GLSL parser error, "syntax error", on line 74 concerning the 'frags' variable in oit.fs. Regarding the blur recipe, it says "line 63 in blur.fs -- built-in function parameter type check fail: offset must be a constant / literal in texture functions." The next error I encountered is more of a concern than an error in Chapter 7. The program runs fine, but I'm getting a 'Invalid operation' error message coming from GLUtils::checkForOpenGLError( ... ) method, but there doesn't appear to be any errors when the program runs (I just thought I should bring it up regardless). The next issue I came across is a Segmentation Fault in Chapter 10 for 'cloth' recipe and I think it might be the TGA loader. The program just opens and then seg faults. I didn't seem to have any issues with any of the other TGA loaded programs though. Lastly, I though I should mention that I had to make a minor adjustment for Chapters 9 and 10. When I clone the repository, the GL major / minor versions were 4.4 for chapters 9 and 10 (which kind of threw me off since all the others were 4.3). It's not really an issue since I can just change it, but it threw me off at first and it might be helpful to somebody that only has OpenGL 4.3 (especially since chapters 1-8 all use OpenGL 4.3).

When I saw that most examples can run MasOs from this github page I was so interested in trying that immediately on my MasOs Sierria with Xcode 9.2.

With the latest glfw snapshot I did build all the examples successfully. When I tried the chapter 6 point sprite example, I got the runtime error message saying that the pointsprite.vs can't be opened.

Here is the code line: prog.compileShader("shader/pointsprite.vs");

I found the root cause issue is in Xcode debug, the current working directory is <...>/chapter06/Debug. However, in fact "shader" directory is at the same level as "Debug" directory. Further, "media" directory is at the same level as "chapter06" directory.

So if we follow the instructions in the github only we are not able to run any examples.

Please suggest any solution on this. Is there any Xcode setting for changing the working directory?

On Windows in visual studio express 2012 i get the error message:

Error 1 error LNK1107: invalid or corrupt file: cannot read at 0x1C196

and on Linux:

Hi David,

Nice book and nice recipes! Unfortunately I could not wait for the new edition.

I had some problems to compile the code in VS 2010 because of glDebugMessageCallback(GLUtils::debugCallback, NULL).

I had to change "void GLUtils::debugCallback" to void APIENTRY debugCallback.

Thanks,
Eduardo

I know I've gotten this to build on linux before (Ubuntu I think), but I'm currently on Manjaro w/kernel 4.9.142-1-MANJARO. I've tried both clang (v:7.0.0) and gcc (v:8.2.1)., and my build command is

cmake -DCMAKE_CXX_COMPILER=clang -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_CXX_STANDARD_LIBRARIES="-lm" ../

and I got these linker errors.

The problem when you compile as correct ??!

How to fix this?

hi,

I got this error when compiling the teapot object:
error C2719: 'lidTransform': formal parameter with __declspec(align('16')) won't be aligned

I'm using Visual Studio 2013. It can be fixed by changing the type from 'mat4' to 'mat4&', but I'm not sure if it is the best way to do it.

Projected texture example doesnt show a working projected texture, just a teapot. It is loading the flower.png texture without errors... I'm not sure why I can't see it working.

Compiled in VS2015

The last line tells that there was a segfault.

Compilation failed due to using glm/gtx/transform without proper enabling of the glm experimental extensions.

To fix this I added this macro to the cookbookgl.h file (which seems to be included by all other main files)

#define GLM_ENABLE_EXPERIMENTAL

My system configuration:
OS: Ubuntu 14.04 64 bit
GLM: v0.9.9.0
GLFW3: v3.2.1

I know this basically says "redo all of chapter 9", but this is a pretty real issue actually.

Apparently this method uses point sprites.

There are two big issues with using point sprites, as I took a week of debugging to finally find out :(

Apparently, (a) a lot of hardware has a point size limit of 64.0. This tutorial goes up to 200, and setting it to 64 is just really small.

The other big issue is that when the center of a point sprite goes off-screen, the whole thing is clipped.

It'd be really cool if you could make another version of this same approach using something like geometry shaders or whatever. I really want to have a "particles like smoke, fully on the gpu"

mat4() should be mat(1.0f). The original generates a zero matrix.

It should be possible to support OpenGL 4.1 core for many of the examples (excluding Chapter 10). This would enable MacOS users to run the examples.

• Chapter 1
• Chapter 2
• Chapter 3
• Chapter 4
• Chapter 5
• Chapter 6
• Chapter 7
• Chapter 8
• Chapter 9

The GLM transform2.hpp header is no longer appropriate for this code, we should be using transform.hpp.

cmake is fine

hi

wondering if the code in scenebasic.cpp at line 134 is correct?

// Create and populate the buffer objects
GLuint vboHandles[2];
glGenBuffers(2, vboHandles);

here vboHandles is a local variable, while the variable with same type and name is member of scenebasic in header:

class SceneBasic : public Scene
{
private:
int width, height;
GLuint vboHandles[2];
GLuint vaoHandle;

although these are never referred directly afterwards.

On some displays, the viewport is too small. We need to use the framebuffer size, not the window size when setting the viewport.

For some reason, I need to #include <stdio.h> to all main.cpp files in every chapter.
Compiled under Ubuntu 12.04 LTS.

When executing ./chapter01 basic (on linux), I get the following error message:
Error opening file: shader/basic.vert

A solution is to copy the directory from source path to build path. I suppose there is a more elegant solution using cmake...

The noise examples don't look quite right since the transition to GLM. They need to be tweaked to make the images look better.

How to solve this problem?

What license is this code available under? (I grepped the files here and the book itself but couldn't find any mention of a license.)

I have an original copy of the OpenGL 4.0 Shading Language Cookbook and noticed there is a second edition and was wondering what has it changed between the editions?

I try to compile "sceneoit", but the compiler not found setupFBO function in cpp file.

CMake Error at CMakeLists.txt:6 (find_package):
