What does major and minor mean in OpenGL with GLFW?

由 为君一笑 提交于 2021-02-19 06:05:26
问题 I was creating an OpenGL window with GLFW on some Dell PC that used integrated graphics. I thought that major means maximum and minor means minimum. However having a restricted version range of (3,3) works but a range that contains it such as (4,2) fails. Example: //fails glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 4); glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3); //fails glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 4); glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 2); //success glfwWindowHint

glGenFramebuffers() access violation when using GLFW + GLEW

问题 I am getting this error: "Access violation executing location 0x00000000." when I use GLFW + GLEW on Windows. I am using Windows 7. I also have my own implementation (from scratch) that that creates a window, initializes OpenGL context, initializes GLEW, etc... and everything works fine. So of course my video card has the Frame Buffer capability and everything is pretty fine with the drivers... the problem only happens when I try to use GLFW. Any suggestion? The code: void start() { if(

Instancing cubes next to each other OpenGL

由 自古美人都是妖i 提交于 2021-02-11 07:59:12
问题 I tried to instance many cubes side by side each other. My understanding is that I need to create a MVP matrix for each cube and bind this then somehow change the position. then run this in a for loop for how many cubes you'd want. This is what I've tried: while (!glfwWindowShouldClose(window)) { glClearColor(0.0f / 255.0f, 170.0f / 255.0f, 204.0f / 255.0f, 0.0f); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glUseProgram(programID); glEnableVertexAttribArray(0); glBindBuffer(GL_ARRAY

Syntaxerror 'varying' in GLSL

由 馋奶兔 提交于 2021-02-07 19:02:55
问题 I'm using GLFW 3 and OpenGL 4 + GLSL 4 on a MacBook Pro. I get the following syntax error, when starting my program: ERROR: 0:5: 'varying' : syntax error syntax error The shader code: #version 410 varying vec3 vertex; void main() { } Why am I not allowed to use varying variables? 回答1: Why am I not allowed to use varying variables? Because they have been replaced by the more generic in / out variable concept since GLSL 1.30. That became necessary because with GL3, the geometry shader was

Looking for a simple OpenGL (3.2+) Python example that uses GLFW [closed]

问题 Closed. This question does not meet Stack Overflow guidelines. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 7 years ago . Improve this question I am looking for a simple modern OpenGL (3.2+)example in Python. I tried with GLUT and freeGLUT, but I am not able to get a 3.2 context on OS X (Mavericks). (This seems to be a known issue with GLUT/freeGLUT). GLFW seems to be a modern lightweight alternative to

Passing in C++ Method as a Function Pointer?

由 て烟熏妆下的殇ゞ 提交于 2021-02-05 11:14:33
问题 I've created a class called InputControl. I am using a library called GLFW, and a function glfwSetKeyCallback. The function is defined as: GLFWkeyfun glfwSetKeyCallback ( GLFWwindow * window, GLFWkeyfun cbfun ) Typedef is as follows: typedef void(* GLFWkeyfun) (GLFWwindow *, int, int, int, int) The issue is that I can not convert my method to a function pointer. I feel like I've tried to cast it in every way possible. I'm not sure how else I need to cast this method. Is there something that

Display 2D text with freeglut, using OpenGL

由 懵懂的女人 提交于 2021-02-05 09:24:42
问题 I'm pretty new into this and I'd like to display fixed location 2D texts (like level, life, score etc.) on my game's screen which is basically a 3D game. I have found a few similar questions but still could not figure out the solution for me. I mainly use GLFW for everything but I'd like to use glut for displaying texts. I have a funcion (based on a few other questions I've found here) to try out how it works but I'm not sure how exactly can I make it to actually display because now
