OpenGL OGRE or just OpenGL?

Recommended Posts

I want to start learning how to code 3D graphics. I planned on using OGRE, because I have heard a lot of good things about it. However, after several hours of work trying to get it working with my IDE+compiler to no avail, I'm wondering if I would be better off just learning OpenGL myself and doing things that way. I really don't want to waste another afternoon trying to get compiler/environment crap working, I want to code. Is there any reason I should not just start learning OpenGL?

What problems are you having? Maybe if you post them here we can help you resolve them in minutes. Basically with Ogre, you'll be able to jump straight into game development, while if you start with OpelGl, it will be a while before you even contribute one line to the actual game.

I'm using Codeblocks and the MinGW compiler. As far as I can tell, I would need to replace my compiler with their own special version of it.

Additionally, all I can find about Codeblocks are several conflicting (and all very old) wiki articles on how to get it working. I spent a few hours the other day figuring out how to compile the OGRE source. I finally did it, sort of, but I had to install and use CMake and VC++ to do it. Today, I noticed an SDK for MinGW, and that looked a lot easier when I checked it out. The samples actually had source code. But as far as I can tell, that is not specifically for Codeblocks, and it actually requires a DIFFERENT different MinGW to work.

What problem are you running into exactly? You said you were able to compile Ogre, can you compile and run the sample apps?

Any reason you can't just use VC++ for your project?


Honestly, I'm just not willing to change my entire programming environment for one library. Plus I really like Codeblocks. Or did you just mean the compiler? Because I guess I could try that out and see if it's simpler.

As for compiling the sample apps, I don't even know where to begin. I don't know what to link with, etc. There is no singular up-to-date guide that I've been able to find. I've found a couple on the wiki, but they contradict on another and both seem to refer to ancient versions of OGRE.

EDIT: I have been trying for the past while to get it working in Codeblocks with the VC++ 2008 compiler. I've gotten close, but I can't get past the linking stage. I just now decided to at least see if it works in the VC++ 2008 IDE, and that failed, too. Both of these attempts are using the VC++ 2008 version of the OGRE SDK, of course. This is all too bad, I really think it I want to use a library like OGRE instead of learning OpenGL from the ground up. :-(

Also, I thought OGRE was supposed to be cross-platform? I tried searching their forums, and found some "just use VC++" answers. Seems kind of unhelpful for people who might not want to make a Windows only game.

NEW EDIT: Ok, I got it working with Codeblocks+MinGW! I found that Codeblocks has an OGRE project template, so I used that to figure out the stuff I needed to start out. It wouldn't work until I copied some files into the OGRE SDK's include directory, but I got that fixed. I also had to download a custom MinGW setup. I can now compile and run that template OGRE app though, so I think everything is working :)

      Hi all,
       
      I'm starting OpenGL using a tut on the Web. But at this point I would like to know the primitives needed for creating a window using OpenGL. So on Windows and using MS VS 2017, what is the simplest code required to render a window with the title of "First Rectangle", please?

      Hi, New here. 
      I need some help. My fiance and I like to play this mobile game online that goes by real time. Her and I are always working but when we have free time we like to play this game. We don't always got time throughout the day to Queue Buildings, troops, Upgrades....etc.... 
      I was told to look into DLL Injection and OpenGL/DirectX Hooking. Is this true? Is this what I need to learn? 
      How do I read the Android files, or modify the files, or get the in-game tags/variables for the game I want? 
      Any assistance on this would be most appreciated. I been everywhere and seems no one knows or is to lazy to help me out. It would be nice to have assistance for once. I don't know what I need to learn. 
      So links of topics I need to learn within the comment section would be SOOOOO.....Helpful. Anything to just get me started. 
      Thanks,

      Hi all,
      First time poster here, although I've been reading posts here for quite a while. This place has been invaluable for learning graphics programming -- thanks for a great resource!
      Right now, I'm working on a graphics abstraction layer for .NET which supports D3D11, Vulkan, and OpenGL at the moment. I have implemented most of my planned features already, and things are working well. Some remaining features that I am planning are Compute Shaders, and some flavor of read-write shader resources. At the moment, my shaders can just get simple read-only access to a uniform (or constant) buffer, a texture, or a sampler. Unfortunately, I'm having a tough time grasping the distinctions between all of the different kinds of read-write resources that are available. In D3D alone, there seem to be 5 or 6 different kinds of resources with similar but different characteristics. On top of that, I get the impression that some of them are more or less "obsoleted" by the newer kinds, and don't have much of a place in modern code. There seem to be a few pivots:
      The data source/destination (buffer or texture) Read-write or read-only Structured or unstructured (?) Ordered vs unordered (?) These are just my observations based on a lot of MSDN and OpenGL doc reading. For my library, I'm not interested in exposing every possibility to the user -- just trying to find a good "middle-ground" that can be represented cleanly across API's which is good enough for common scenarios.
      Can anyone give a sort of "overview" of the different options, and perhaps compare/contrast the concepts between Direct3D, OpenGL, and Vulkan? I'd also be very interested in hearing how other folks have abstracted these concepts in their libraries.

      I recently started getting into graphics programming (2nd try, first try was many years ago) and I'm working on a 3d rendering engine which I hope to be able to make a 3D game with sooner or later. I have plenty of C++ experience, but not a lot when it comes to graphics, and while it's definitely going much better this time, I'm having trouble figuring out how assets are usually handled by engines.
      I'm not having trouble with handling the GPU resources, but more so with how the resources should be defined and used in the system (materials, models, etc).
      This is my plan now, I've implemented most of it except for the XML parts and factories and those are the ones I'm not sure of at all:
      I have these classes:
      For GPU resources:
      Geometry: holds and manages everything needed to render a geometry: VAO, VBO, EBO. Texture: holds and manages a texture which is loaded into the GPU. Shader: holds and manages a shader which is loaded into the GPU. For assets relying on GPU resources:
      Material: holds a shader resource, multiple texture resources, as well as uniform settings. Mesh: holds a geometry and a material. Model: holds multiple meshes, possibly in a tree structure to more easily support skinning later on? For handling GPU resources:
      ResourceCache<T>: T can be any resource loaded into the GPU. It owns these resources and only hands out handles to them on request (currently string identifiers are used when requesting handles, but all resources are stored in a vector and each handle only contains resource's index in that vector) Resource<T>: The handles given out from ResourceCache. The handles are reference counted and to get the underlying resource you simply deference like with pointers (*handle).  
      And my plan is to define everything into these XML documents to abstract away files:
      Resources.xml for ref-counted GPU resources (geometry, shaders, textures) Resources are assigned names/ids and resource files, and possibly some attributes (what vertex attributes does this geometry have? what vertex attributes does this shader expect? what uniforms does this shader use? and so on) Are reference counted using ResourceCache<T> Assets.xml for assets using the GPU resources (materials, meshes, models) Assets are not reference counted, but they hold handles to ref-counted resources. References the resources defined in Resources.xml by names/ids. The XMLs are loaded into some structure in memory which is then used for loading the resources/assets using factory classes:
      Factory classes for resources:
      For example, a texture factory could contain the texture definitions from the XML containing data about textures in the game, as well as a cache containing all loaded textures. This means it has mappings from each name/id to a file and when asked to load a texture with a name/id, it can look up its path and use a "BinaryLoader" to either load the file and create the resource directly, or asynchronously load the file's data into a queue which then can be read from later to create the resources synchronously in the GL context. These factories only return handles.
      Factory classes for assets:
      Much like for resources, these classes contain the definitions for the assets they can load. For example, with the definition the MaterialFactory will know which shader, textures and possibly uniform a certain material has, and with the help of TextureFactory and ShaderFactory, it can retrieve handles to the resources it needs (Shader + Textures), setup itself from XML data (uniform values), and return a created instance of requested material. These factories return actual instances, not handles (but the instances contain handles).
       
       
      Is this a good or commonly used approach? Is this going to bite me in the ass later on? Are there other more preferable approaches? Is this outside of the scope of a 3d renderer and should be on the engine side? I'd love to receive and kind of advice or suggestions!
      Thanks!

      I 'm learning how to create game by using opengl with c/c++ coding, so here is my fist game. In video description also have game contain in Dropbox. May be I will make it better in future.
      Thanks.
