Given a set of selected faces (triangular only) from single mesh, how can we detect following: a) edge loops that selected faces create.
If I have a list of 3D points and their 2D projection on screen, is there a way to compute the camera that performed the projection?
I want to know if a ray from an arbitrary point will strike a polygon. It would be开发者_如何学运维 useful to know the point in space that intersection occurs and also a reference to that polygon. I\'
I\'m using matplotlib to plot some data as 2D curves in a 3D axes. 开发者_开发知识库I use the ax = axes3d.Axes3D() to define my axes and ax.plot(x, y, zs=\'z\') to plot my 2D curves in the 3D space.
Given that: The shape is a regular polygon in 3D space The start point (the end of one arbitrary vertex of the shape) is known
I\'ve recently engaged on studying WPF (to be honest, I\'ve gotten into it just because there was built-in 3D object, camera and rendering capabilities), which has allowed me to do this:
I was building a 2D project in OpenGL ES 1.1 but decided to switch to 2.0 since I was only going to be developing for the iPad.
I\'m simulating a physical object, using a mass spring system. By means of deltas and cross products, I can easily calulate the up, forward an开发者_运维技巧d side vectors.
In my game i\'m currently working on, i only need very basic physics, so i don\'t want Newton, ODE, Bullet or similar. I basically only want to fall as long as no node (all equally sized blocks) is be
I was wondering why there is no X11 driver for the mali 3D arm gfx chip.I looked into building an X11 driver for the avail开发者_如何学Cable kernel driver, but could not find any documentation on how
