RenderHog: open source cross platform shader prototyping tool (RenderMonkey clone)
|
What?
I've released the first public version of RenderHog (version 10.10.09.2).
What's RenderHog?
RenderHog is a cross-platform GLSL shader development environment. RenderHog takes care of interacting with OpenGL 3 and allows the user to load as... |

Postprocessing with large kernels: what to do about the edge of screen
|
I'm applying a particularly large Gaussian blur kernel as a post-process effect. I'm encountering artifacts at the edges of the image, where part of the kernel reaches off of the screen. I tried doing wrap, clamp to edge, and mirror for the texture a... |

Baking Static Ambient Occlusion Maps on the GPU
|
Despite the trend toward screen-space ambient occlusion, static ambient occlusion maps are handy for improving the realism of non-deformable objects like cars or spaceships with no impact to framerate. However, baking them in Blender as I usually do... |

Allocate my main game object on the stack, on the heap, or in the data segment (C++)
|
All of my game subsystems are contained inside a GAME object that's the highest level object in my game's class hierarchy. The GAME class exposes a public "Start" function, which kicks off the main game loop and doesn't return until the user quits t... |

Tetrigami, an origami-themed tetromino game
|
Tetrigami is an origami-themed tetromino game. The game came to be largely due to this gamedev article about how to build up to making cool independent games. To summarize, the article recommends starting with simple, small projects. Tetrigami is tha... |

Which functional language, and why?

My background is in C++. I'd like to learn a functional language, and there are several options... as part of my decision making process I thought I'd poll others on which language they picked, and their reasoning. So: which functional languag... |

Sensor display for a space ship user interface

I've been brainstorming ideas for a sci-fi spaceship game for a while. My goal is for the gameplay to be similar to Privateer or Freelancer, but I want the interface to be mouse driven (ala EVE Online) with an emphasis on simplicity. O... |

Contracting out to a freelance artist

This is a hypothetical, but I could see myself being in this position in a year or two. Let's say I'm an independent developer working as the sole developer on an independent commercial game. I'm able to do all of the coding, the music, and so... |

Multithreading my game engine -- slower than expected performance
|
My game engine, vastly simplified, does two things: simulate the game world, then render the game world. Note that I'm including getting input and some other subsystems as part of the "simulate" step.
Based on this forum discussion, I decid... |

RenderHog: open source cross platform shader prototyping tool (RenderMonkey clone)

I realized I wasn't redistributing all of the .dll files needed to make this work out-of-the-box for someone without GTKmm installed. Version 10.10.16 fixes this so please give it a shot. The latest version will always be available at this link:

NFAA - A Post-Process Anti-Aliasing Filter (Results, Implementation Details).

I implemented this in OpenGL/GLSL and at first I was disappointed with the results... but after playing with it a bit I got pretty decent results. The most important thing I found was clamping Normal.xy before doing the texture lookups:
Normal.xy =... |

Smooth object on obj file format
|
Oh, I understand now. Your graphics API will interpolate vertex normals for you if you're using OpenGL or DirectX, but if you're writing your own software rendering, the method you used should work, as far as I know. |

Wheel blur shader?

In Portal, Valve used a camera motion blur that samples in an elliptical path:

Maybe you could do something similar, sampling around an elliptical path that c... |

Smooth object on obj file format
|
If your .obj exporter can export per-vertex normals, you have enough information to be able to render the object with the smooth areas smooth and the flat areas flat. Your 3d package's exporter should take care of getting the vertex normals correct f... |

Survey for shader writers

How often do you write shaders, and how much experience do you have with them?
At the moment I'd say an average of one shader a week. I've been writing shaders in my spare time for maybe 3 years.
What shader language do you use?
I use G... |

GPU particles collision detection with arbitrary mesh

It won't always provide correct results, but you could render depth from an ortho camera on each axis, then use that to bound your particles. |
