I am just starting to learn OpenGL today from this tutorial: http://openglbook.com/the-book/ I got to chapter 2, where I draw a triangle, and I understand everything except VAOs (is this acronym OK...

I'm trying to render multiple objects in OpenGL using multiple VAO's and VBO's. To render multiple objects using the same vertices I've done it, but what I want to do is to use different vertices f...

I need to create a grid like this: ---------------- | | | | | | ---------------- | | | | | | ---------------- | | | | | | ---------------- and rendering it just with lines. This is how I ...

I'm trying to draw two triangles in a window in OpenGL 3.3. I'm using the GLFW library for the windowing system. From what I understand, I should have two VBOs (one for each triangle) and one VAO ...

As far as I understand it: A VAO represents a certain state. If I bind a VAO, add some VBOs and element buffers for indicies and stuff I can save a certain state of the object(s) I want to draw and...

Suppose I set up two VAOs, using the new (as of OpenGL 4.3) glBindVertexBuffer mechanism: glGenVertexArrays(1, &vaoIndex0); glGenVertexArrays(1, &vaoIndex1); ... glBindVertexArray(vaoIn...

When created, do VAOs track just VBO indices (via glBindVertexBuffer), or also which VBO names are bound to those indices? If I specify a binding index of, say, 0 using glVertexAttribBinding during...

Im facing an issue which I believe to be VAO-dependant, but Im not sure.. I am not sure about the correct usage of a VAO, what I used to do during GL initialization was a simple glGenVertexArrays...

I currently do this to setup my vao: glBindVertexArray(vao); glBindBuffer(GL_ARRAY_BUFFER, vbo); ... glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, ibo); glBindVertexArray(0); My question is: do I need...

I'm trying to wrap my head around how to use VAOs appropriately for instanced rendering (specifically in Qt 5.2, using OpenGL 3.3). My understanding is that VAOs save the state of the VBOs and asso...

I am trying to understand these two, how to use them and how they are related. Let's say I want to create a simple terrain and a textured cube. For both objects I have the array of triangles vertic...

I am writing an OpenGL3+ application and have some confusion about the use of VAOs. Right now I just have one VAO, a normalised quad set around the origin. This single VAO contains 3 VBOs; one for ...

How can I get the name of the currently bound Vertex Array Object? I looked in the manual but couldn't find an enum to use with glGet().

I have the following code which should simply draw a green triangle to the screen. It is using Vertex Array Objects and index buffers to draw and has the simplest shader I could make. At first I w...

Question 1 Do vertex buffer objects created under a certain VAO deleted once that VAO is deleted? An example: glGenBuffers(1, &bufferObject); glGenVertexArrays(1, &VAO); glBindVertexArr...
