Thunder Carrot (My 3D Modeler!)
|
WHAT IS THUNDER CARROT?
Thunder Carrot is a simple 3D modeler I'm working on. My interest is in 3D games and I wanted to make a minimal tool that I could use to create characters, design maps, etc. Enjoy the screenshots - there's not much m... |

Sound Recording and Playback at the Same Time
|
I am running Windows 7, 64-bit, programming in C++.
I want to feed audio input from a microphone to the speakers in real time. I tried using the Win32 WaveIn and WaveOut APIs, but the latency was much to large (as in, > 800 ms).
What is the... |

Real-Time Digital Sculpting
|
I'm working on an application that will allow users to digitally sculpt into a triangle mesh. Rendering is done in OpenGL.
The basic concept is that users can sculpt into a mesh with a pillbox-shaped tool (a pillbox is a cylinder with half-s... |

Video Decoding
|
Hey everyone! I'm looking for a [free] C/C++ library that decodes video files in common formats (preferably at least MPEGs). And by "decode", I just mean I want the ability to get the bitmap data for each frame (so I can save each frame to a file a... |

Some Quaternion Functions - Enjoy
|
I recently implemented skeletal animations, and for smooth interpolations I used quaternions and the SLERP algorithm.
Quaternions are weird extensions of the complex number system. But you don't really need to know anything about them to use them... |

Skeletal Animation - Transitioning to a new animation?

What do games normally do, for example, when a character switches from a running animation to a jumping animation? I'm about to implement skeletal animation, and I'm unsure if I should even implement inter-animation interpolation at all.
Do games... |

Scaling Normals
|
I was thinking about this common scenario: You scale your geometry with a scaling matrix, but then your normals get scaled as well. This results in incorrect lighting.
To combat this, we could use D3DRENDERSTATE_NORMALIZENORMALS (idk what the Op... |

Anyone use Scintilla?
|
It's a code-editing control. It makes things like syntax highlighting really easy...almost.
My problem is that it seems to not apply syntax highlighting to a keyword if that keyword is the last part of a document.
Anyone else get this problem?... |

A Slight Variant of Modern Exception Handling

So I've been thinking about exception handling a lot lately, and I'm trying to make it just a little bit better (I'm working on a scripting language right now).
Here's what I've got so far in a C++ish syntax:
// there is an implicit try... |

Error while building in visual c++ express 2010

I always choose "Empty Project" in Visual Studio. Then it decides automatically whether to create a console window based on whether you have a main or a WinMain. Also it doesn't add any MFC, AFX, or any of that Microsoft weirdness to your proj... |

Merging 2 video files?
|
You could also write a simple C++ application to do this for you (shouldn't take more than a few minutes). Use OpenCV to read and write the videos. It's free and you might learn a little doing it. |

Drawing line wider than 1px with DirectX
|
I would suggest drawing polygons that are more than 1px wide.
A thick line is really just a rectangle. Plus, if you have anti-aliasing on in general, it should give you anti-aliased lines, too, when they are composed of polygons.
Addition... |

Small buffers - got it. But I'm also trying to do an FFT on the data - and from my knowledge of FFTs, larger buffers give more accurate fourier transforms. I'm trying to determine the fundamental pitch of the mic input in real time - I guess t... |

root engine - landscape

For image loading I suggest FreeImage. It's what I use in my projects. It's fast and loads all the popular formats.
Also, I can see the seams in your skybox. If you're using OpenGL, you can fix this with:

Wait, so DirectX 11 works on DirectX 9 level hardware, but DirectX 10 doesn't? |

make a matrix not modify a coordinate

I'm not sure what you mean. You mean like expanding it out to see all the dot products?
I have looked at an expansion of matrix multiplication before. I can't seem to figure it out.
I'm tempted to just write a vertex shader that sets the w co... |

make a matrix not modify a coordinate
|
Indeed, I know how matrix multiplication works. But I can't just make that row (0, 0, 0, 1). That would affect the other coordinates, wouldn't it? I'm pretty sure it would. |

surface normals

Another way to do it would be to cast a ray from the center (well, the center isn't particularly important, but it gives you a starting point) of every polygon out to infinity in any direction. Count the number of OTHER polygons it hits. If it hits... |
