    Efficiency of VAO with VBO for every Model

    So, I've been trying to find out the best way to render ~1000 models on screen. I see two general approaches to this. Some people pack their entire scene into a single giant VBO and load that in. I...

    Thanks for the input. I decided to go with a VBO per object. They are just small quads and there will only be ~150 on screen during the most hectic of times. Unfortunately, now im having other...

    My question is what would be the best way to debug and possibly see what the issue is? Is there a way to see exactly what the MVP looks like in the shader? Is there a way to verify what vertices...

    Well, even though my first tests are small, it may likely get much larger. I am just trying to learn the best-practices. From what I have seen, it seems like storing everything in a single VBO, then...

    Multiple objects in a VBO or Multiple VBOs?

    So, I am trying to figure out the best way to draw all of my objects. Should I have multiple objects in a single VBO, or should I have a VBO per object? It seems like having a VBO per object is the...

    So, I did a little research, and I guess I should be using a translation Matrix. The issue I have is that I don't want to move a set amount, I want to be able to hand OpenGL it's new coordinates. So...

    Moving vertices in Programmable Pipeline

    Hey guys,
    So I have a simple OpenGL program up and running that draws a square using the programmable pipeline. How do I actually tell the vertices to change their location? Do I edit the vertices...

    Cirenkual, once again thanks for the help.


    So then textures with 100% transparent areas would work fine?

    Thanks for the info Cireneikual.



    Are you saying that for each object I should just call glUseProgram (desiredShader); every time I draw an object?


    For Deferred Shading, I have looked at a...
  12. Using different shaders on objects, and multiple shaders on one object

    I couldn't decide if this belonged in the GLSL section or not, but I kept if here because I assume this is less related to GLSL than to the way OpenGL handles shaders.
