Cocoa/Objective-C memory leak when printing
|
Hi!
I have spend the last few days trying to find a memory leak in my code. Instruments (the Apple tool that detects memory leaks, among other things) reports leaked memory when printing from my app. I could not find the leaking code so I made a r... |

[DX10] Multiple viewports.
|
Hi!
I am trying to implement multiple viewports in my game engine. It kind of works, but I cannot seem to find any info on how to draw the graphics so that one viewport can be "on top" or "below" another. Eg. I might have one viewpo... |

Problem with adding pointer to std::map
|
I am implementing a resource pack system into my engine, where you can request resource packs from the resource manager, by giving it the name of the pack. For this I decided to use the std::map container since it makes it easy to get an element by k... |

Please comment on this memory chunk allocator
|
Hi!
I have started playing around with memory allocators for game engines after reading Jason Gregory's Game Engine Architecture book. One of the types of allocators he mentions is a chunk allocator, in which the allocator class maintains a li... |

C++ Stack allocators - data alignment and sizeof
|
Hey there!
I'm trying to write a simple stack allocator for my game engine. As I understand the objects that are allocated should be aligned according to how much memory they need. Integers are (usually) four bytes wide and so should only res... |

[DX10] Obj files and index/vertex buffers

Hi!
I have written a small obj file loader for DX10, which loads the data and creates an ID3DX10Mesh used for drawing. The loader works quite well, and I am able to load meshes with multiple groups and textures just fine. I do have a question abou... |

Strange SVN commit problem

Hi!
I am having problems committing a Google Ads library file to SVN. The filename is libGoogleAds.a and when adding it to a folder TortoiseSVN is automatically giving it the "ignore" icon. There are no ignore properties set for .a files in the wo... |

Hi!
I have followed Bobby Anguelov's tutorials at http://takinginitiative.wordpress.com/ for help creating a small graphics engine. The engine works great except that I get the message "Invalid parameter passed to C runtime function." in the outpu... |

Is this singleton thread safe?

I have searched the internet for some C++ singleton patterns, and have come across some that are mentioned as thread safe and some non thread safe, but I have not really understood what it is that makes a certain pattern thread safe. I have, in my pr... |

The Sketchy Project
|
Yo!
The Sketchy Project is a game prototype/tech demo I have been working on for a while now. The project was born when I bought a Wacom Bamboo pen tablet and wanted to draw game graphics. As a programmer I don't draw very well, so I had to c... |

Script language with C++ grammar
|
I'm not aware of any scripting language that would have C++ grammar, but if you like Lua you might want to try Squirrel:
http://www.squirrel-lang.org/
It is inspired by Lua but it looks a little bit more like a C-based language. Im curious, why... |

[DX10] Multiple viewports.

Phew, that's a lot of stuff. I cannot honestly say I know how to do all that, but at least now I know where to start. Thanks! |

[DX10] Multiple viewports.

Yeah well, I still cannot get it working. Since my render target view essentially is a resource view into the back buffer getting two views to that and then clearing them separately does not make any difference since the underlying buffer is the same... |

[DX10] Multiple viewports.

I guess this is a difference with D3D9 and D3D10. From the ID3D10Device::ClearRenderTargetView documentation:
"Differences between Direct3D 9 and Direct3D 10:
Unlike Direct3D 9, the full extent of the resource view is always cleared. Viewport a... |

[DX10] Multiple viewports.

That might very well be the case. I never thought that I would need separate depth buffers for every viewport, but that of course makes perfect sense. I'll try that later tonight. |

[DX10] Multiple viewports.

So, this is my render() method:
void Renderer::render()
{
// Clear scene.
mDevice->ClearRenderTargetView(mRenderTargetView, D3DXCOLOR(0, 0, 0, 0));
mDevice->ClearDepthStencilView(mDepthStencilView, D3D10_CLEAR_DEPTH, 1.0f, 0 );

Beginning DirectX 10: Why my test program uses up 50% dual-core CPU?

This is expected behavior, and you did not really do anything "wrong". As Hodgman already stated, you are telling the computer to fill your window with a single color as fast as it can, which effectively eats up all the power of a single core. This,... |
