How should I manage my VAOs and VBOs?
I'm sure you've heard this question a lot, and I've read thoughts on other forums but I haven't found anything in my search here.
My question is, how should I separate objects among different VAOs and VBOs?
In learning how to use OpenGL, I have been working on modeling objects in 3DS Max, exporting them into the COLLADA format, and I am now working on rendering them in my OpenGL application.
If I have an object such as a car which is made of different parts that are their own geometries in the exported COLLADA file, how should I distribute them into VAOs and VBOs?
Should I make a VAO for each part? (The body, each door, each wheel, etc..) And a VBO for each part?
Should I put all the vertex data into one big VBO? Then use only one VAO?
Should I use only one VAO and then a VBO for each part?
In essence, what is best practice in organizing the separate parts of an object and then in organizing a collection of objects? (multiple cars?!)
Thanks for your help! =)
