Hi everyone, I'm working on a game engine using OSG in which I can load very large game worlds and have it run at a high framerate.
My game world is made up of cubes, and I am building vertex arrays for each "cell" in the level - each cell is 64x64x64 blocks in size. Now I would like to be able to add and remove blocks in-game with minimal impact on my framerate. At the moment I am doing this by destroying the cell's geometry and recreating it again - adding it back into the scenegraph using setVertexArray() (and setNormalArray, setNormalIndices, etc.) This is quite a horrendous operation but remarkably it only takes about 100ms or so. Still, my framerate takes a very noticeable hit when this occurs. How would I best modify my vertex/face/etc. arrays on the fly without the dip in framerate? Should I be looking to farm this operation out to another thread? Is there a way to add and remove vertex data from my arrays so that I do not have to push such a large chunk of data to the video card each time this happens? Apologies if my terminology isn't correct - I'm still learning how OSG (and graphics rendering in general) works! And thanks to all who have put so much work into OSG, I hope to make an F1 racer of a game engine with it someday!
