Need help developing a routine to map a 3D sphere out of blocks
|
Hey all. I want to draw a 3D Sphere out of a bunch of blocks. What I’m looking for is a function that will return me a list of 3D coordinates where if I placed a block at each coordinate it’ll create the shape of a 3D sphere. I’m assuming I’d pass... |

dds vs. jpeg, which is better
|
I've always believed .DDS files were supposed to be better because they're compressed and provide HW support with the compression, right? Therefore, when loaded they don't expand to native size and therefore save space, right?
I noticed on d... |

Hey guys, hoping you can help out. I’m developing in XNA, and using a normal mapping shader on an object I’m getting different results on windows and xbox. I don’t think either is right, but want other opinions.

Object alignment (aka billboard)

Hey guys,
I’m not sure if this requires a billboard or if I’m overcomplicating it.
I have a Matrix as follows:
Right/X axis
UP/Y axis
Forward/Z axis
I want to align the UP/Y to 0,1,0 and adjust the Forward/Z to whatever it s... |

3D Camera rotation on a fixed origin help

Hoping you can help. I think the math is pretty basic 3D math, but that's never been my forte. I haven't been heads down programming for a while and just getting back into it I'm pretty rusty with the 3D details.
I'm trying to create a camera wh... |

Need help developing a routine to map a 3D sphere out of blocks

I think the brute force will give me what I want. I was originally thinking of that but didn't want it to return a cube, but a sphere instead. I think the addition of:
int sum = i * i + j * j + k * k;
if (sum <= radius) {

I got my issue resolved, I needed tangent data, and I wasn't using a tangent pipline function I had. I've since merged the tangent function and a bounding box function (the pipeline I was using) into a single pipeline, and now everything works perfe... |

I went a simpilar route and it seems to work, tell me what you think?
// perform initial rotation
newMat = newMat * Matrix.CreateRotationX(rotationY);
// Calculate the DOT and Cross relative to 0,1,0
-- left out code for this

Thanks Sirob, this is just what I was looking for. However, glsensor is right, is there a c++ version of this anywhere? If not, I'll try and convert this, but I'm not really familiar with C#, so I don't know if this is easy or hard. I guess I'll f... |

It looks like they specifically create the stencil buffer as part of the device using:
