OpenGL OpenGL 2d Hockey Rink

Recommended Posts

Looking for tips on how to draw a 2d hockey rink, for use later in a game. Something similar to the surface in NHL 96 (Sega Genesis). I was thinking drawing the flat ice first (square with textured bitmap) and then the lines, and then the boards, logos, etc... The problem is later on I''ll need to be able to easily calculate collisions. Unfortunately there is little documentation on hockey games on the WWW. Any advice appreciated.

Use OpenGL. Draw the lines and make the rink. For the boarders put in pictures and such. Also, instead of looking up hockey on the WWW, check out programming and 3D API''s such as opengl

Thanks, I''ve already found that project and looked
into it. None of the links to download on that
web page work, and the source code isn''t on the ftp.

If you have the source code to the mhockey project, or
know where to get it, that''d be appreciated. I emailed
all the addresses on that web page and they all come
back "user unknown". Maybe Electronic Arts bought them
out or something

I have drawn a rink with simple lines to scale of an actual
NHL rink. I think what I''m going to need are the following:
- Textured Ice Quad for Main Ice Surface
- Textured Red line and blue line quads to overlap the main ice surface (I hope once I get going I can modify the ice texture to look skated on)
- Faceoff Circles
- Red lines coming off these cirles (slot area)
- Textured goal net quads
- Textured plexi glass quads (transparent)
- Not sure how to handle the corners yet.

For an idea of what i''m kind of going for:
www.cs.dal.ca/~rodgers/NHL96_000.bmp and
www.cs.dal.ca/~rodgers/NHL96_001.bmp
I''ll post what I come up with (should be funny) in a couple
days.

Hey, tried to send you the source to mhockey 0.50 at the e-mail address specified in your profile but the mail borked with this (changed the address in this posting for yer privacy):

The original message was received at Thu, 24 Oct 2002 17:04:42 -0300 (ADT)


----- The following addresses had permanent fatal errors -----

(reason: 501 5.1.3 Path data: Perhaps this should have been a dot (.) instead of colon ( ?)


If you have another address to send it to post it in another message and I''ll send you the source (~400k), if you want the windows binaries/models/grafix/sounds I have them too (~1.4 meg) ...

draw a quad for the ice surface with a repeating texture that looks like ice (either smooth glassy ice like NHL94 or the snowy ice with shavings on it from NHL95... or if you''re badass transition from one to the other over the course of the period). After the quad draw the blue and red lines, the circles, face off dots, etc either using glLines and such or with textured polygons, but regardless of which you use blend it with the ice surface. For the boards, glass, and seats you might want to use a modeler if you want anything halfway decent.

I emailed you from an address to send the files.
It''s greatly appreciated!! mHockey is a 3d project
which might be a little out of my scope, but I think
it''ll show me a lot of useful things. If you didn''t get
the email, the address is rodgers AT cs.dal.ca

Thanks for the great advice! I am going to load up
NHL94 tonight and NHL96 and compare the ice textures.
NHL96, Damn you New Jersey devils! (Me == Wings Fan)
I found NeHe''s tutorial on blending:
http://nehe.gamedev.net/tutorials/lesson.asp?l=08
Hopefully that will help me with making the red line
look like part of the ice.

- There are tutorials out there on making glass in
OpenGL, might look at them later on. For now a
decent bitmap that I can texture at both ends will
suffice. Now if I could make something where you could
see the players reflection slightly when they are
in the corners, while still seeing the fans behind the
glass, now that would be sweet.

- As for transitioning the ice between glassy and snowy,
not sure how I''d do that. Knowing OpenGL, it''s probably
not too hard.

      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!

      I want to make professional java 3d game with server program and database,packet handling for multiplayer and client-server communicating,maps rendering,models,and stuffs Which aspect of java can I learn and where can I learn java Lwjgl OpenGL rendering Like minecraft and world of tanks

      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.
