Defining 3d-object orientation
|
Hi.
I would like to know how I can form orientation matrix for a 3d-object by defining a local up vector for the model and a rotation angle around that vector (represents heading).
This is seems by far the most intuitive way to define orientation... |

Null-pointer crash when using VBOs
|
I've ran into very strange problem with my OpenGL application. I get occasional null-pointer crashes when I'm trying to draw geometry stored as VBO.

I am also experiencing strange behaviour in my application when I don't use the VBO drawing. The GL_COLOR_ARRAY client state seems to set itself enabled and corrupt graphics. It's definitely not set enabled by glEna... |

Null-pointer crash when using VBOs
|
Putting the components into distinct VBOs seemed to fix the crash. Thanks a lot for your help!
But I'm still puzzled what was wrong with glInterleavedArrays? |

Played the game through. The success in the game is much more dependent on luck than actual skill or strategy. If you get right runes to summon archers and mages, you'll have no problem winning the game.
Some bugs:

Nightgate Defense

I barricaded the whole road and the game ended up in deadstill. The snakes weren't able to move through the barricades and I wasn't able to get new runes by killing them, as it seems that you can't move your soldiers when the enemies attack.

Got to finish the game first, and then possibly release ports for other OSes later.

The font used for your score blends in way to much with enemy bullets. It should stand out more.
The score font is actually pulsing fast like a neon lights using AC voltage, thus making them stand out from backg... |
