Graphics / VertexArray Question

« on: March 02, 2012, 06:44:53 pm »

I do have a question after all.

I'm new to graphics and OpenGL so forgive my ignorance. Say I have a VertexArray with 100 quads in it. Is it guaranteed that it will be drawn in the order 0 to 99? Is there any occasion that would make it drawn backwards or in a random order?

Graphics / VertexArray Question

« on: March 02, 2012, 06:15:56 pm »

I've been going through the new graphics API and I'm confused about something.

I'm trying to figure out why we can't modify the vertices in a VertexArray. I see we can read them just fine but what if we want to move the texture coordinates or transform them?

Am I just missing something or is this really not possible?

EDIT: Nevermind, I just found the answer in another thread. Sorry about that.  :oops:

Graphics / Graphical glicth: horizontal lines in SFML2

« on: October 31, 2011, 06:47:37 pm »

Hello everyone, this is my first post. I've been using SFML for a while now and I love it. Thanks for your hard work, Laurent.

I have this unwanted line problem also. I'm confused as to what I need to do. Using easy's advice to convert the view to integer coordinates doesn't work for me. And Haikarainen, I don't understand what you have suggested. Could you clarify please?

My view never moves. I render my game at 1280x720 and use the view to scale it up or down, depending on the resolution. Here is where I set my view:

Code: [Select]

MainView->Reset(sf::FloatRect(0, 0, 1280, 720));
MainView->SetViewport(sf::FloatRect(0.0f, 0.0f, 1.0f, 1.0f));
MainWindow->SetView(*MainView);

That never changes. I get the lines when I'm not rendering to a native 1280x720 resolution or window size. Does that mean I'm out of luck? Is there any hack I can apply? Am I doing this completely wrong and should I be using another technique instead of using the view to scale my game?

Edit: I just looked into RenderTexture. Would this be the correct way? I could render the entire scene into a texture and then scale that to the window? Would there be a performance hit for that?

Edit again: I just tried the RenderTexture. It was so easy to change over. It works perfect now. I can scale my game to any resolution without the lines showing up. I'd still like to know if I have the right idea though.
