In Topic: Why didn't somebody tell me?

Then last month I was in Australia and they had a feature on the radio talking about things you really should know, but only just found out recently. Someone called in saying that every car fuel gauge on the dashboard has an arrow on it indicating which side the fuel cap is on.


Not true in my experience. At least not on older cars.

Probably copy-and-pasted from a tutorial or a library...

In Topic: What different kinds of 3D modeling are there besides CAD modeling?

Typically people will equate "CAD geometry" with NURBS. NURBS are usually used in CAD because they can perfectly represent circles and arcs.

In Topic: What does this mean: 0 < r, g, b, a < 1

r,g,b,a ∋ (0,1) ∋ .. (provide some numbers set)


Considering that (0,1) is typically an open range (excluding 0 and 1) and a closed range is more typically expressed with [0,1] this is no less confusing ;)

So the first trick I suggest is to apply some environmental lighting. How you want to do it is dependent on you. What I suggest are two different enviormental lighting layers.


Environmental lighting in space? I assume we're talking about an inter-planetary travel kind of situation where we're not up close to any planet surface and where we can't distinguish too many detailed planetary surface features. Tell me, which large surface exactly does the light from a nearby star reflect off of to warrant a strong environmental/bounce light influence? Yes, there's always going to be some amount of indirect light hitting any surface, but in a setting where objects are separated from each other by massive distances this is going to be quite negligible.


Of course you can use artistic freedom and paint in very bright and colorful nebulae all over the place which drastically influence a planet/celestial body's surface in some way, but this doesn't seem very realistic to me.


Honestly, the only time you'd actually get any benefit of doing a shadow implementation at all at this level of detail is if one celestial body occludes incoming light from a star to another celestial body (an eclipse) which is actually somewhat rare as far as I know.


Maybe Tangletail meant the lighting situation if only starlight is present? In interstellar space with no nearby stars that light would be nearly omnidirectional ('environmental').
