Papervision 3D programming tutorial: Effects

Keep Reading ...

Another article from series of programming Papervision 3D tutorials demonstrates the use of Flash filters with Papervision 3D objects. Papervision has the ability to use some interesting effects like blur, glow and drop shadows, to add some visual flare to 3D renderings, and the good news is that, just like Flash, these effects are very [...]

Quaternions in Papervision 3D

Keep Reading ...

Andy Zupko’s explanations on the very basics of how you can use Quaternions in Papervision, and how to get the motion you see in the demo.  For those who don’t have a solid mathematical background it may be a difficult concept to undrstand. But the author gives forcible arguments in favour of quaternions. The most [...]

Very informative and detailed article on how to create a Papervision Planetarium. Demo shows real constellations found on sites like NOMAD (they use standard astro-celestial coordinates). The author used particle technique to make this planetarium. In general, there are lots of things things you can do with particles: make fire, smoke, a flock of birds, [...]

Pixel Precision in Papervision 3D

Keep Reading ...

Today pixel perfection became one of the important components of a great website. While achieving pixel precision in Papervision 3D you may face such problems:
- a material should be rendered as in 1:1 scale of the original texture
- a precise pixel level match between 2d and 3d content is necessary
This tutorial offers some magic formula [...]
