Opengl Get Error String


The error flag will be set to GL_INVALID_VALUE, and our call to glBufferSubData() will do nothing. Later, we’ll discuss OpenGL Hints, which allow you to instruct the rendering engine to make tradeoffs for the sake of speed, or image quality. If the last one occurs, the state is undefined, which is really scary and you don't want that. If it really is that they don't, is there any good reason for why that is so? his comment is here

Now we don’t want to turn this chapter into a course on software engineering and quality assurance, but if you want your programs to run smoothly, you need to account for In the following posts, I'll explain some smarter ways of debugging OpenGL, which does not clutter up your code with error checks. To support these requirements I have create a small function and a macro which let you check for OpenGL errors using a single command. When Bad Things Happen to Good Code Internally, OpenGL maintains a set of six error status flags.

Coleman 30.9k23063 That sounds absolutely great, but I see that extension doesn't seem to be available on any of the Intel GPU drivers I see around, which is, of OpenGL is a C-based API, which means that there is no support for exceptions. some opengl calls] /// glCheckError(); /// #define check_gl_error() _check_gl_error(__FILE__,__LINE__) #endif // GLERROR_H GLError.cpp #include "GLError.h" #include #ifdef WIN32 # include #elif __APPLE__ # include #else # include #endif Glgeterror Example Whenever you do something bad in OpenGL, an error flag is raised.

Gl Error 1280 It would seem as if the error occurred when we allocate data using the other buffer, when in fact it didn't.

OpenGL drivers are implemented for specific devices, after all. this content Every time an error is detected a flag is set and a numeric code is recorded. Our problem now, is that we no longer know exactly what function call caused the error, only that an error occurred somewhere. For example, tried to buffer more data than the allocated memory can hold, forgotten to upload data, forgotten to set correct uniforms, and so on. Gl Error 1281

The first seems like it will cause quite a bit of overhead, and lead to some bloated code. When this routine is called, and the error flag is set, it will display the error type and the source file name (useful when working with multiple files) and line number the function is silently ignored. http://xhpcreations.com/gl-error/gl-error-string.html Related Posted in C++, OpenGL | Tags: debugging « Cross-platform desktop OpenGL 3.2 using Qt4.8 Debugging OpenGL part 2 – using glDebugMessageCallback() » Leave a Reply Cancel reply Enter your comment
