|
Hello you!
As i'm slowly moving closer to a good understanding of Vertex Buffer Objects, i stumbled upon a question.
Consider this; You have many objects (minimum 10, and maximum 10000) in a 2D space. The objects are all just textured cubes, bu... |

Hello people!
In my game, i use one vector to store all my objects. At max, there might be around 100 objects contained within the vector, so it's not that crowded. But! I've noticed an issue while adding objects to my vector. Sometimes, when... |

Maybe it's time that i learn shaders then. Sadly, i have no idea what they or nor how to use them. But a few well spent hours on google should take care of that :) |

It doesn't work with a texture atlas unless you use shaders.
Okey. Hmm, then i guess the question is; Which is best?

Thanks for all your answers!

I had no idea there was such a performance gain from using a texture atlas. I'll keep this in mind... |

"You have to have a context created first" got me thinking. Turns out i constructed my VBO before i setup my context. Gah, stupid mistake. Thanks a million though for all your help!
I'd make you a cake if i could! |

It seems to me like you have not put enough data into your buffer. objectVertices has only 8 values, should this not be 9? Like {x,y,z,x,y,z,x,y,z}? I usually test these things by drawing GL_POINTS since its behavio... |

Calling glGetError after binding my VBO the first time, returns an invalid operation. This comes from somewhere previous in my code though, since if i call it before binding i get the same result. Just don't want to leave anything out.
