22 thg 11, 2016 · With that out of the way, unless your objects share vertex data you are generally going to need a unique set of VBOs for each. You can use a single VAO for your entire software if you want, or you can take advantage of the fact that changing the bound VAO changes nearly the entire set of states necessary to draw different objects. Thus, drawing your terrain and cube …
22 thg 10, 2020 · A VAO is an object that stores vertex bindings. This means that when you call glVertexAttribPointer and friends to describe your vertex format that format information gets stored into the currently bound VAO. And when you draw it will use the vertex bindings in the currently bound VAO. Pretending it replays the binding calls is misleading.

24 thg 10, 2014 · 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...
6 thg 8, 2012 · VAO is an object that represents the vertex fetch stage of the OpenGL pipeline and is used to supply input to the vertex shader. You can create vertex array object like this
20 thg 11, 2014 · If you free a VBO bound to a VAO, the VBO isn't actually 'freed' until it's no longer bound to the VAO (but you can't bind it anymore). Dumping the whole state machine is also fairly impractical; OpenGL is quite a huge state machine.
2 thg 2, 2015 · Unbind the VAO Creating a VAO is very simple: GLuint vao_name; glGenVertexArrays(1, &vao_name); This will generate one vertex array, and store it's name in vao_name. Once your VAO is created you need to bind it: glBindVertexArray(vao_name); Now, any changes you make to the attribute pointers or bindings to the element array buffer will be …
7 thg 2, 2019 · 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 for each object, for example to draw a square and a circle.
23 thg 11, 2015 · Not the VAO, but the buffer you want to modify. Since your bindings are saved in you VAO, in your case binding the VAO or binding your GL_ELEMENT_ARRAY_BUFFER is the same for glBufferData. However sometimes it's not the case.
