The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. The free ebook is available through CRC Press by clicking here. The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

OpenGL
How many use OpenGL?

I think you missed a "not"
Generally, 3D games is not programmed by Direct3D...

Most 3D games sold are not for Windows. Another thing to remember is that over 90% of the commercial game projects that is using Direct3D is losing money.

To be honest do I think that a discussion like this is pointless. What you can do should be more important.

I think OpenGL is much better than Direct3D and we all should support it! M$ has enough money and we must stop them to control everything of the pc market!

The only thing which is better in D3D is D3DX and it''s helper functions for vertices,matrices and so on.... we should create such a thing for OpenGL..or is there something similar?? Don''t know...

...OpenGL 1.3...I think we all know why M$ stops releasing new OpenGL versions for Win.

I agree M$ is not the kind of firm I want to support, and I use OpenGL to release a game on many platforms at once.
(Linux, BeOS, Windows [money guys], maybe MacOS and freeBSD)

About D3DX I think it''s called glu in OpenGL :p

There''s also GLUT at a higher level.

I''m porting my engine to SDL+OpenGL right now (from the Win32 API and XLib). After I''m done it''ll be readilly compilable on Linux, Win32, BeOS, MacOS, Solaris, IRIX, and FreeBSD. All without changing a thing. The joys of OpenGL . The only annoying thing is dealing with the different directory structures in each OS, but that''s not too bad (I found a way around that).

The thing with SDL is by the license agreement you''re required to release your source code if you use it. If you''re making something open source that''s fine but if you want to release something commercial and don''t want to release your code, then I wouldn''t use SDL.

I don''t use OpenGL, not at all. Nope, not me.

Anyhoo, I sure hope this won''t turn into a Direct3D vs. OpenGL flame war, cuz I''d have to take out my big shiny sword on this thread (wink wink nudge nudge), so keep it civilized.

i believe the latest sales figures show less than 15% of games sold in 2000 were for pc''s.

... which is fine, except that this thread is about OGL vs. D3D ... and most consoles DON''T use OpenGL. So I fail to see what Obelix''s point is.

Let''s see : Sony PS2, Nintendo GameCube and (rumors)the Xbox have an OpenGL implementation...

Guess what, I think you can use OpenGL on consoles.
Also you can use it on windows if you wish and you can use it for your favorite OS probably.

Cross dev for console, PCs in a single API that''s good
(of course you''ll have to change things a bit, but not that much)


And to answer the first question :
Noone is using OpenGL, see there''s no questions about OpenGL in this board, and John Carmack isn''t coding DOOMIII using almost every GeForce3 capabilities.

Sorry, but that is a misconception. SDL is under the LGPL and not under the GPL. This means, you only have to release your sourcecode if you mix your sourcecode with theirs. Use their sourcecode for your own purposes, and link with SDL dynamically and you should be fine.

To qoute the license page, at their site (www.libsdl.org)

The most common way to comply with the license is to dynamically link with SDL, and then include the SDL source code and appropriate notices with your application

The Dreamcast and the XBox support D3D. So I guess it''s tied at two until the final verdict on the XBox is in . My point is, this isn''t exactly a commanding lead for OpenGL.

Xbox will support OpenGL. Nvidia made the graphics system in the X-Box and nvidia has been a leader in OpenGL performance and features over the past few years. I doubt they would shoot themselves in the foot now by NOT supporting OpenGL.

And yes.. using SDL doen NOT meant you have to release you game OpenSource, if you expand SDL source directly you have to release your modifications, but not if you are just using the API.

OpenGL is supported on almost every high end graphics device I know of ( including all consoles ). It''s a nice well rounded API that has the full possibility for hardware accelleration ( including t&l ) without any modifications.

OpenGL is one of the best example of a portable library there are, it can scale from CPU driven to almost completly hardware accelerated without a single code change. D3d as I understand it is only NOW w7 & 8 getting to the point where it can hope to compete with OpenGL in terms of ease of use and expandability.

To say that Dx & D3d are the only API for mainstream gaming would be sticking your head in the ground and not using some of the most popular games as examples.

      So it's been a while since I took a break from my whole creating a planet in DX11. Last time around I got stuck on fixing a nice LOD.
      A week back or so I got help to find this:
      https://github.com/sp4cerat/Planet-LOD
      In general this is what I'm trying to recreate in DX11, he that made that planet LOD uses OpenGL but that is a minor issue and something I can solve. But I have a question regarding the code
      He gets the position using this row
      vec4d pos = b.var.vec4d["position"]; Which is then used further down when he sends the variable "center" into the drawing function:
      if (pos.len() < 1) pos.norm(); world::draw(vec3d(pos.x, pos.y, pos.z));  
      Inside the draw function this happens:
      draw_recursive(p3[0], p3[1], p3[2], center); Basically the 3 vertices of the triangle and the center of details that he sent as a parameter earlier: vec3d(pos.x, pos.y, pos.z)
      Now onto my real question, he does vec3d edge_center[3] = { (p1 + p2) / 2, (p2 + p3) / 2, (p3 + p1) / 2 }; to get the edge center of each edge, nothing weird there.
      But this is used later on with:
      vec3d d = center + edge_center[i]; edge_test[i] = d.len() > ratio_size; edge_test is then used to evaluate if there should be a triangle drawn or if it should be split up into 3 new triangles instead. Why is it working for him? shouldn't it be like center - edge_center or something like that? Why adding them togheter? I asume here that the center is the center of details for the LOD. the position of the camera if stood on the ground of the planet and not up int he air like it is now.

      Full code can be seen here:
      https://github.com/sp4cerat/Planet-LOD/blob/master/src.simple/Main.cpp
      If anyone would like to take a look and try to help me understand this code I would love this person. I'm running out of ideas on how to solve this in my own head, most likely twisted it one time to many up in my head
      Thanks in advance

      I googled around but are unable to find source code or details of implementation.
      What keywords should I search for this topic?
      Things I would like to know:
      A. How to ensure that partially covered pixels are rasterized?
         Apparently by expanding each triangle by 1 pixel or so, rasterization problem is almost solved.
         But it will result in an unindexable triangle list without tons of overlaps. Will it incur a large performance penalty?
      B. A-buffer like bitmask needs a read-modiry-write operation.
         How to ensure proper synchronizations in GLSL?
         GLSL seems to only allow int32 atomics on image.
      C. Is there some simple ways to estimate coverage on-the-fly?
         In case I am to draw 2D shapes onto an exisitng target:
         1. A multi-pass whatever-buffer seems overkill.
         2. Multisampling could cost a lot memory though all I need is better coverage.
            Besides, I have to blit twice, if draw target is not multisampled.

      Hello

      I am working on a recent project and I have been learning how to code in C# using OpenGL libraries for some graphics. I have achieved some quite interesting things using TAO Framework writing in Console Applications, creating a GLUT Window. But my problem now is that I need to incorporate the Graphics in a Windows Form so I can relate the objects that I render with some .NET Controls.

      To deal with this problem, I have seen in some forums that it's better to use OpenTK instead of TAO Framework, so I can use the glControl that OpenTK libraries offer. However, I haven't found complete articles, tutorials or source codes that help using the glControl or that may insert me into de OpenTK functions. Would somebody please share in this forum some links or files where I can find good documentation about this topic? Or may I use another library different of OpenTK?

      Thanks!

      Hello, I have been working on SH Irradiance map rendering, and I have been using a GLSL pixel shader to render SH irradiance to 2D irradiance maps for my static objects. I already have it working with 9 3D textures so far for the first 9 SH functions.
      In my GLSL shader, I have to send in 9 SH Coefficient 3D Texures that use RGBA8 as a pixel format. RGB being used for the coefficients for red, green, and blue, and the A for checking if the voxel is in use (for the 3D texture solidification shader to prevent bleeding).
      My problem is, I want to knock this number of textures down to something like 4 or 5. Getting even lower would be a godsend. This is because I eventually plan on adding more SH Coefficient 3D Textures for other parts of the game map (such as inside rooms, as opposed to the outside), to circumvent irradiance probe bleeding between rooms separated by walls. I don't want to reach the 32 texture limit too soon. Also, I figure that it would be a LOT faster.
      Is there a way I could, say, store 2 sets of SH Coefficients for 2 SH functions inside a texture with RGBA16 pixels? If so, how would I extract them from inside GLSL? Let me know if you have any suggestions ^^.

      EDIT: I thought this was restricted to Attribute-Created GL contexts, but it isn't, so I rewrote the post.
      Hey guys, whenever I call SwapBuffers(hDC), I get a crash, and I get a "Too many posts were made to a semaphore." from Windows as I call SwapBuffers. What could be the cause of this?
      Update: No crash occurs if I don't draw, just clear and swap.
