How to correctly approximate a sphere ( collisson sphere ) to an object, say cube?
|
Simple answers now. As the title asks, how is this done 'correctly' in openGL?
Give a generic answer that applies to any object, to save time. Give a specific exemplification if you can. |

Is there any way for extremely efficient collission detection.?
|
I would like to know if there is a relatively simple means to perform extremely efficient collision detection.
Tired of seeing 3d objects overlapping other 3d objects now.

Real Reflection Question

So, I and I just decided to learn reflection, via openGL's powerful stencil buffer functionality.
B4 u leave, check out the issue i have bottom the post, and download my little reflection test! controls are on screen:

Real Time Damage for non-mathematicians and mathematicians alike.....

An idea come to I... real time damage. Further more, the solution involved no math...( basic rotation and subtraction )
I decided to draft up this idea, don't know if it's valid...I think my writing is sufficiently legible:

What is the fastest method to tesselate terrain?
Uses 'stencil shade/blend technique' to simulate lighting per vertex ( my little hack )

FreeImage Issue

I fixed the image lading error, never mind.
What i realized, was that in my image loader, bpp, pr bit depth was wrong.
When I modified img loading code to a .png loader instead from .bmp loader,
forgot to change the GL_RGB bit in glTexImage2D ( )... |

I don't know why you post this in opengl, it's not really relevant.
OpenGL doesn't do these kinds of things for you, it just draws meshes that you give it.
Anyway, what I would do in your case is just pick a poi... |

One big dynamic VBO, or multiple small static ones?
|
One big VBO is better. According to Eskil Steenberg, standalone super programmer, single VBO implementation is sufficeint. I might be mistaken. |

FINAL SOLUTION!!!!!!!!!! CHECK IT OUT.
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT|GL_STENCIL_BUFFER_BIT);
glLoadIdentity();
glTranslatef(0.0f, 0.0f, zoom);
glRotatef(RotationX,1.0f,0.0f,0.0f);

They type of calculation will have to be geared towards two natures, direction and acceleration based. Direction would involve the 'rotative' behaviors that the face would adopt. Acceleration will be the speed or time in which this 'rotative' manner... |

I think I might have came up with an extremely simple solution.
This involves sphere bounded method though. Simple, but if moulded and ingeniously implemented, deep calculus II is avoided.
Lol, a simple thing like combined radii of two objects... |

The important thing is that you have set the 20'th value in your static pixel format descriptor function, to 1.
