| Apple Catcher for iPhone is out | Hi! I posted about this in my developer journal... but I don't think all that many people read it ;) Nevertheless I like to present a newly released game called Apple Catcher developed by OddGames. The goal of the game seams trivial at first but as... |

| iPhone alpha testing | Has anyone tried to render a lot of graphics using opengl alpha test on the iPhone? I have read that alpha testing is SLOW on the iPhone. Is it out of the question to rely on alpha testing for the majority of the graphics in a game eng... |

| Rymdraket!! | My team and I (my two brothers and I) developed a game called Rymdraket during 2002-2003. It's a multiplayer game set in space, sort of like thrust but against other players. Because of a hard drive crash the game was partially lost and hence I could... |

| removing item in std::list | Hello! I am converting a data structure from linked list pointers to std::list. Previously I had two functions for removing items in a linked list. The first function deleted the item using delete myPointer; and redirected the neighboring pointers... |

| Copy depth texture | Hello! I am trying to copy a shadow map texture into another texture using glCopyTexSubImage2D but to no avail. Is it possible to copy depth data from an fbo using that function? If not, can I do it in another way? Any help appreciated. |

| Blurring shadow map | Hi! I am trying to blur a shadow map but am having some performance issues. The easy solution; sample the neighboring fragments (shadow2D()) as many times as desired and divide the result equally. This causes bad performance with just 4 samples. I ha... |

| ATI shadow map filtering | Hello! I am having issues with an ati card (radeon x1650 pro) when doing shadow mapping. Using an nvidia graphics card I can get nice bilinear filtered shadows. With ati I can only manage to get nearest filtered shadows using the same functions... |

| Blur artifact | Hi! I'm having trouble with my bloom shader. The shader blurs my scene in two passes, first a horizontal pass then a vertical pass. When I render my screen aligned quad I get a seam that stretches from corner to corner of my screen: The s... |

| glUseProgram | I've made a lighting shader system which uses one shader for each number of lights. Let's say I've got two lights then I would use: glUseProgram(two_lights_prg) ...and for one light i would use: glUseProgram(one_light_prg) I was... |

| npot textures | How do OpenGL deal with textures which are in npot-format when the graphic card lacks support for it? Does the texture become all corrupt or does it rely on some sort of mip-maps instead? |

| SDL Isometric | It's not much different from doing it in any other framework. I am using win32 for my map editor and sdl for a game I'm creating which relies upon maps created in the editor. Tile selection is more dependent on your isometric setup than on... |

| Using 3D boxes for isometric view | I sent you a PM :-) it's great to see more people interested in isometric games! :-) |

| Apple Catcher for iPhone is out | Thanks! I have painted it with standard graphics tools. Gimp is free and sufficient. The animations are created with Pro Motion 6, a cheap painting program. |

| Simulating water | Draw a texture that has some repeating ripples and bind it to a quad. Adjust the UV coordinates over time to make the ripples move. Then set slight transparency so that the ground can be seen through the water and voila, you got some tacky water. |

| Directx vs Opengl | DirectX is not an equivalent of OpenGL. They are both good however. Write a small app and find out for yourself. If you are on Linux or OS X you have no choice but to go with OpenGL. |

| Shadow Mapping Slight Problem | You should only apply the shadow map on the diffuse and specular components of a fragment not the ambient. In glsl this is quite easy. With fixed function you need to render the scene in two passes (I think, I could be wrong). One pass... |

| My Isometric Engine | Wow, very nice! But how come you are using low resolution graphics for the backgrounds when the character and objects are in high resolution? It’d also be interesting to hear about how you calculate and render your penumbras. |
