Any improvments for my Sphere Collision Algorithm
|
Today i sat down in wrote me a function which checks if 2 moving Spheres collide or not because I need this for my Game projekt.
And I wondered if there are any improvments performance wise which can be done.
Ps: I tested it a bit but would be gl... |

No Java game developers on this forum...?
|
same thought as Jason Petrasko, all the more difficult questions go to the OpenGL/Graphics Theory forums or a more general questions. |

One big dynamic VBO, or multiple small static ones?
|
sure, if u want to rotate your spirits, then just calculating the 4 vertices on the CPU will be easier for you.(One could distinguish between rotating and not rotating ones ;-) )
@Erik Rufelt
I'm agreeing with you, using point spirits w... |

I can't really agree with Erik Rufelt here.
1. When I profiled my app once I found out that binding Textures was the function which took the longest time to process then any other function. I had a little game which had also some game logic... |

Bloated class and organization in JOGL
|
this is not that much of a JOGL relate problem then just a general problem you encounter.
You will always have some where a function/method which will start the rendering of a frame(not the window "JFrame").
Some basic Idea would be to have a... |

|
so when u don't use shaders u can't use a texture atlas(TA) with point spirits(PS), only one. In this case i would recommend to use a TA and create one VBO for each Texture so u will only have to change each Texture once.

So because you were talking about 2D, if u really meant cubes or quads?
If so you could use point spirits(u just have to provide 1 Vertex for each quad).
Also be sure if u really move every object per frame or just the camera.
In this case u c... |

Render point array into a 3D texture
|
yes I finally found out how to do this :-)
I was curious how others had done this(crytek) cause obviously copying 500 textures isn't quite efficient.
it seams as crytek stated it is only possible with DX10 capable hardware, because a geometr... |

Render point array into a 3D texture
|
in the specs it says:
"blit operations only read from the color buffer specified by glReadBuffer and will only write to the color buffers specified by glDrawBuffers."
so you can only read from one buffer, but can write to mult... |

Optimal alignment of vertex data
|
I think that u would only see some measurable difference if u used some strange vertex sizes like 23 or so. I think that I read somewhere that 32bit is the best value, because the memory registers(??) on the GPU are 32bit big. And to load t... |

Geometry shader, point sprites to spheres
|
ok lets see:
- i just assume that your look at function works
- point size stuff shouldn't matter, because you already got spheres to display with that code
viewmatrix:
you have a 3x3 matrix in your shader but are trying to send a 4x4 matrix.... |
