Radius of Convergence of Infinite Series Why can't we use the toilet when the train isn't moving? If an error occurs, you need to be able to stop and say “Hey, an error occurred, and this is what it was.” This is the only way in code that This makes it easier to localize your program for use with another language. 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

This means that whenever you call a function with some illegal parameters, the function are capable of throwing a runtime exception telling the programmer what he did wrong. Gl Error 1280 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 When to use "bon appetit"? https://www.opengl.org/wiki/OpenGL_Error gluErrorString function The gluErrorString function produces an error string from an OpenGL or GLU error code.

Just look up the error values from the gl2.h and gl.h headers (they start with 0x05). Gl Error 1281 Started by Cacks, Mar 26 2006 06:21 AM Old topic! 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. You can look to a newer version here: https://github.com/HujiangTechnology/gradle_plugin_android_aspectjx.

Gl Error 1280

For example, the error flag GL_INVALID_ENUM returns the string invalid enumerant You can take some peace of mind from the assurance that if an error is caused by an invalid call https://blog.nobel-joergensen.com/2013/01/29/debugging-opengl-using-glgeterror/ share|improve this answer answered Jul 18 at 10:52 Gregory Stein 227 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign Gluerrorstring So when I faced this issue (tracing GL errors) it appeared as a classic problem for AOP. Opengl Error 1282 You will have the following output: 07-18 12:34:37.715 19167-19187/com.example.neutrino.maze D/GlEngine: GlState[]: no error 07-18 12:34:37.715 19167-19187/com.example.neutrino.maze D/GlEngine: GlState[draw]: no error 07-18 12:34:37.733 19167-19187/com.example.neutrino.maze D/GlEngine: GlState[]: no error 07-18 12:34:37.735 19167-19187/com.example.neutrino.maze D/GlEngine:

The programmer need to query the OpenGL error state when one or more OpenGL calls have been made - this is done using the glGetError function.

So obviously I made quite a few mistakes in my program. Join them; it only takes a minute: Sign up OpenGL ES Error to String up vote 3 down vote favorite Is there a standard for getting an error string from glGetError() You may have a good reason for using such optimization tricks; it’s certainly faster to use TextOut than to call wglUseFontBitmaps. (Of course, if you do have this fancy-dancy video card, Glgeterror Example Where are sudo's insults stored?

Each flag represents a different type of error. OpenGL is a C-based API, which means that there is no support for exceptions. Then you buy one of those fancy, warp drive accelerator cards, and the vendor throws in a new rendering engine. OpenGL provides you with two different methods of performing an occasional sanity check in your code.

I had some experience with it in C# in the past (some 7 years back) with SpringFramework and PostSharp. True or False? But wait … there is more This blog post explained the fundamentals of debugging OpenGL. The error check must be in a loop since many errors can be have happened since last error check.

Rebuild to find if you have any issues. 2) Add our annotation which we'll use later to mark methods we want our aspect to be applied to: package com.example.neutrino.maze; import java.lang.annotation.ElementType; Other than that you could also make some wrapper like template void checked(F fn) { fn(); auto error = glGetError(); if(error != GL_NO_ERROR) throw std::runtime_error("OpenGL error: "+std::to_string(error)); } ... void display() { glClearColor(1.,0.,0.,1.); glClear(GL_COLOR); // error - should be GL_COLOR_BUFFER_BIT check_gl_error(); glutSwapBuffers(); // Glut specific swap } The program now output the error enum name as well as the file asked 3 years ago viewed 2734 times active 3 years ago Related 0Render string to texture in Android and OpenGL ES1All OpenGL ES 2.0 functions return 792Loading 3D objects and textures

Best option is to encapsulate inside a logging class that disables glError unless an error was found in the previous frame. Debugging with glGetError() Most people are used to work with a programming language that supports exceptions.

When this error occurs, the state of OpenGL is undefined—indeed, the state of your program may be undefined!

It is certainly nice that the program now tells that an error occurred but what we really want is a more descriptive error message telling us the name of the OpenGL error For convenience, it's displayed below. Syntax C++ Copy const GLubyte* WINAPI gluErrorString(  GLenum errCode ); Parameters errCode An OpenGL or GLU error code. This value is then cleared when glGetError is called, and recalling glGetError will return either another error flag or GL_NO_ERROR.
