OpenGL DirectX / C++ Programming?

Recommended Posts

Well I have VERY basic knowledge of C++, but I was wondering if there is anyway to learn how to create workable graphics in DirectX without knowing how to program? Or do they go hand in hand? Also, I have some more questions that some of my searches did not turn up: -Does DirectX require any prerequisite knowledge? -What programs are required? -Are there any good online sites to learn from? -Are there any good books to learn from? -Does a game that runs DirectX, automatically run DirectX graphics? -What are the pros/cons of DirectX vs. OpenGL? And some topics a bit farther off, but I'm hoping some may answer: -What are some graphics jobs other than modeler, texture-izer(?), landscaper? -Are these doable in DirectX? -I have mediocre art skills, what would be the best area to head into, as they all interest me? -How did you learn your profession, how long did it take, and what do you recommend doing/differently? Thanks, if anyone answers one of these questions, I will consider it a success. I'd love to learn graphic art, and I am willing to spend 2-3 hours per day doing it to achieve my goals.

Just to follow up...I just saw below that there is a more relevant section to what I feel this post is about.

Up to the mods though, as I am sure both forums will be very helpful.

Or do they go hand in hand?

Yes they do, acctually i think you should really learn programming first and the jump to game developmemt

yes, you have to know how to programm

-What programs are required?

A text editor and a compiler, but you will help yourself alot if you use a IDE like Visual Studio, to do the art, well you use blender, maya, 3D Studio max, photoshop, paintshop pro, ms paint or many many others

-Are there any good online sites to learn from?

yes, in fact you are in the best one.
also check The Zbuffer, and many more, just to a search in google for "DirectX Tutorials"

yes. you should have a look to Frank Luna's Introduction to 3D Game Programming with DirectX 9.0 it s great

nop, directX is a set of libraries, but a game can choose to use other thing ( like OpenGL) to do the graphics stuff

the only one i really understand is that, you can program for OpenGL and use it on several plataforms ( Linux, windows, mac,... ) but directX only on Windows
And some topics a bit farther off, but I'm hoping some may answer:

you should look in gamedev.net game jobs section to see if there is something you like

i dont undertand what you are asking.

that really deppends on you.. you should look close to see what is about each one of the areas, and then make a informed desition.

im in college, i recommend you do the same.

Edit: fixed some things, an realized this is my biggest post :D

I think you misunderstand what DirectX is. DirectX is an API; a collection of (programming) interfaces designed to aid in the development of various game-related "things" (such as audio, input and graphics). Direct3D is the subset of the DirectX API that is concerned with graphics.

Direct3D is not a "tool" in the traditional sense of a program like Maya or 3DS Max. You must write programs to be able to use it, and you must do a lot more than just make calls to the Direct3D API to yeild a workable game or other application.

To answer some of your specific questions:

No. If you mean "graphics" like "3D models," there are tools (actual applications) like Maya, or 3DS Max (both expensive) or Milkshape (much more affordable).
Quote:
Does DirectX require any prerequisite knowledge?

Yes. You should be pretty comfortable writing C++ (or C#) code. Familiarity with the mathematics and theory going on under the hood of the API (geometry, linear algebra, the graphics pipeline, et cetera) is required in some way shape or form once you move beyond trivial demos.
Quote:

Does a game that runs DirectX, automatically run DirectX graphics?

This is pretty much a nonsensical question regardless of what you are defining "graphics" to be. A game using Direct3D to render images can use geometry data (models) defined in any format. A game can use other aspects of DirectX (viz., DirectInput) without using Direct3D.
Quote:
What are the pros/cons of DirectX vs. OpenGL?

DirectX effectively limits you to a single platform. Other than that, it depends on which API's interface style you prefer.

Consider applying to an art school; practice and improve your skills. It sounds like you want to be the guy creating textures/models for a game (the artist) rather than doing programming (the programmer) and dealing with DirectX.

Would you like my life's story while I'm at it? :)
Stay in school, study hard. You get out of education what you put into it, and your education and how you apply it (viz., demos or a portfolio) is your best springboard into the industry.

Thank you for the very well written and informative answers!

I think you are right in assuming that I understood DirectX wrong. What I'd like to do is create the art for games. Character models, buildings and the like.

Would I use 3DSMAX for this? Or this this not so much a field, as programming DirectX is?

That is the case. Functionally, they are equivalent at this point. Outside the core, however, is D3D's standard library D3DX. It has quite a few things that aren't included in OpenGL (or GLUT), like mesh loading / manipulation, animation, global illumination (PRT), etc.

      Hello! As an exercise for delving into modern OpenGL, I'm creating a simple .obj renderer. I want to support things like varying degrees of specularity, geometry opacity, things like that, on a per-material basis. Different materials can also have different textures. Basic .obj necessities. I've done this in old school OpenGL, but modern OpenGL has its own thing going on, and I'd like to conform as closely to the standards as possible so as to keep the program running correctly, and I'm hoping to avoid picking up bad habits this early on.
      Reading around on the OpenGL Wiki, one tip in particular really stands out to me on this page:
      For something like a renderer for .obj files, this sort of thing seems almost ideal, but according to the wiki, it's a bad idea. Interesting to note!
      So, here's what the plan is so far as far as loading goes:
      Set up a type for materials so that materials can be created and destroyed. They will contain things like diffuse color, diffuse texture, geometry opacity, and so on, for each material in the .mtl file. Since .obj files are conveniently split up by material, I can load different groups of vertices/normals/UVs and triangles into different blocks of data for different models. When it comes to the rendering, I get a bit lost. I can either:
      Between drawing triangle groups, call glUseProgram to use a different shader for that particular geometry (so a unique shader just for the material that is shared by this triangle group). or
      Between drawing triangle groups, call glUniform a few times to adjust different parameters within the "master shader", such as specularity, diffuse color, and geometry opacity. In both cases, I still have to call glBindTexture between drawing triangle groups in order to bind the diffuse texture used by the material, so there doesn't seem to be a way around having the CPU do *something* during the rendering process instead of letting the GPU do everything all at once.
      The second option here seems less cluttered, however. There are less shaders to keep up with while one "master shader" handles it all. I don't have to duplicate any code or compile multiple shaders. Arguably, I could always have the shader program for each material be embedded in the material itself, and be auto-generated upon loading the material from the .mtl file. But this still leads to constantly calling glUseProgram, much more than is probably necessary in order to properly render the .obj. There seem to be a number of differing opinions on if it's okay to use hundreds of shaders or if it's best to just use tens of shaders.
      So, ultimately, what is the "right" way to do this? Does using a "master shader" (or a few variants of one) bog down the system compared to using hundreds of shader programs each dedicated to their own corresponding materials? Keeping in mind that the "master shaders" would have to track these additional uniforms and potentially have numerous branches of ifs, it may be possible that the ifs will lead to additional and unnecessary processing. But would that more expensive than constantly calling glUseProgram to switch shaders, or storing the shaders to begin with?
      With all these angles to consider, it's difficult to come to a conclusion. Both possible methods work, and both seem rather convenient for their own reasons, but which is the most performant? Please help this beginner/dummy understand. Thank you!

      A friend of mine and I are making a 2D game engine as a learning experience and to hopefully build upon the experience in the long run.

      -What I'm using:
          C++;. Since im learning this language while in college and its one of the popular language to make games with why not.     Visual Studios; Im using a windows so yea.     SDL or GLFW; was thinking about SDL since i do some research on it where it is catching my interest but i hear SDL is a huge package compared to GLFW, so i may do GLFW to start with as learning since i may get overwhelmed with SDL.  
      -Questions
      Knowing what we want in the engine what should our main focus be in terms of learning. File managements, with headers, functions ect. How can i properly manage files with out confusing myself and my friend when sharing code. Alternative to Visual studios: My friend has a mac and cant properly use Vis studios, is there another alternative to it?

      Both functions are available since 3.0, and I'm currently using `glMapBuffer()`, which works fine.
      But, I was wondering if anyone has experienced advantage in using `glMapBufferRange()`, which allows to specify the range of the mapped buffer. Could this be only a safety measure or does it improve performance?
      Note: I'm not asking about glBufferSubData()/glBufferData. Those two are irrelevant in this case.

      Before using void glBindImageTexture(    GLuint unit, GLuint texture, GLint level, GLboolean layered, GLint layer, GLenum access, GLenum format), does need to make sure that texture is completeness.
