object always visible
|
Hey!
So i have a 3D scene with some 3D objects scattered around. On the scene, there is a "special" object which i'd like to make "always visible". Meaning, even if some other object(s) partialy and fully obstruct(s) it and it normally wouldn'... |

edges on 3d mesh
|
Hey!
Before i start developing my own technique i'd like to ask you if you know any existing methods for determining "sharp" edges on 3d mesh. For example if i have a simple 3d cube model the result of this method would be a list of 12 edges.... |

Hey!
I'm drawing some objects on the screen in perspective projection. Now i'd like to transform perspective projection to ortho projection in few steps so it would look like a smooth transition from one projection to the other. How woul... |

This is the problem i have:
I draw a 3D line in glOrtho. Now i click with the mouse on that line. How do i know which exact point on that line did i click? (object coordinates, not screen or window coordinates)

Hey all. I'm looking for an algorithm which will solve this problem:
Input into algorihtm is a list of 2D points. As seen here:
Now i'd like to calculate a curve (as a list of points) which would look something like this:

unknown matrix

Hey all. Another question.
Lets say i have a model A and model B. I know that model B is just a copy of model A, but transformed by some matrix (this matrix 4x4 contains rotation about custom axis and translation).
Now i'd like to calculate th... |

matrix interpolation

Hey all,
this is the problem i have:
I have 2 matrices3x3. One was created by multiplying several X,Y,Z rotational matrices. The second matrix is generated from angle and axis (rotation about custom axis).
Now i'd like to interpolate f... |

Hey all,
I have the following problem.
I read triangles from a file. The structure of the file is similar to this:
vertices:
x1,y1,z1
x2,y2,z2
x3,y3,z3
.
.
.
triangle idices: ("pointers" into vertex array)
a,b,c
d,e,f

SliverSprite Problem
|
is this a direct source copy paste? because if it is then you have a problem here:
<Canvas<
<game:Game1 Height="600" x:Name="game" Width="800"/>
</Canvas>
see the starting canvas tag

But is it even possible to interpolate between such matrices? (without weird in-between results) |

[SOLVED] point on line

if i convert them to 2D i will only get 2D coordinate of clicked point and that i can not use
or in theory; i could:
- take 2D coordinates where i clicked
- convert to object coordinates using gluUnProject
- (do some more inverse matrix... |

[SOLVED] point on line

well it's not exactly 2D. i have a 3D line so coordinates of the line when it is displayed on screen are not equal to line coordinates (since the line coordinates get transformed from object -> world -> screen space) |

i have 2D (screen and world) representation of the line, projection matrices... i just need to convert mouse click coordinates to line coordinates. |

curve extraction
|
Well this curve would be an approximation of a curve this points originally represented before i applied the noise. So i guess the criteria could be some sort of min(distance(a,b)).
But if i connect closest points i will not get a smooth curve. |
