What is billboarding in 3d?
Introduction. Billboarding is a technique that adjusts an object’s orientation so that it “faces” some target, usually the camera. The word faces is in quotes since it can have several meanings, as the tutorial will show. This technique is quite popular in games and applications that require a large number of polygons.
What is Billboard density?
Pixel density or display resolution is function of the number of individual pixels present on the face of a digital billboard – a significant factor in determining image quality. Out-of-home (OOH) advertisers continue to be attracted to high quality LED digital billboard structures.
How many megapixels do I need for a billboard?
A very common resolution for printing an ad on a very large outdoor billboard is 1800 pixels on the long edge and 1200 pixels in height (about 15 dpi). That equates to a mere 2.1 megapixels.
What does it mean when a billboard faces the camera?
Billboard is a textured flat object, usually a polygon, which faces the camera. Its direction usually changes constantly as the object and camera move, so it always faces the camera direction, this operation is called Billboarding.
What kind of texturing is used on billboards?
Billboards usually use texturing + alpha to represent many phenomena that do not have smooth solid surfaces (e.g. Clouds, Grass, Smoke, Fire). Can or should it be used to create special effects for weapon blasting effects?
What’s the difference between particle systems and billboards?
You need to make a distinction between billboards and particle systems. A particle system is a set of small objects that are animated and controlled using an algorithm. Particles can be represented by Billboards, but other forms are also common such as points and lines.
Can you make gun blasting effects with billboards?
You can make gun blasting effects using billboards, but in the end, you will need a way to control those billboards which will end you up making a particle system (though might be a very simple one) A billboard within your game is always orientated to face the camera.
