comment How to decide to use OpenGL ES 1.0 or 2.0 for Android?
I totally agree with Christian. ES 1 is maybe easier, but one will have to learn ES 2 anyway in a near future. Don't waste time on ES 1, and learn modern (and soon-to-be only) way to do CG.

comment For making an online multiplayer browser-based game, what tech would be more efficient to use?
Same question as thedaian, "efficient" means nothing if you don't define what your goals are. It can be the development speed, the execution speed, the workflow integration with other tools, the most widely supported language, and gazillions of other. Be more specific.

comment How do I respond to keyboard events which occur between polling?
@beeglebug: You could, as David says, just set a "key_pressed=true" on the keyPress event, then just handle it in your mainloop. What I meant is that you don't want to know if a key is down, you want to know if it has been pressed. See the difference ?

comment How can I include vertex color information in .OBJ files?
Why is that a wrong way ? If he just takes the OBJ exporter to make his own, I really fail to see how that's "wrong". The wrong way is not doing any work because it is always the wrong way to someone.

comment How can I convert an OBJ model into arrays of vertices and indices?
I might be wrong, but why are you modifying positions of vertices ? You should end with a vertex list (in the order they appear in the file), and an index list (which refer to the vertices). You don't have to reorder vertices at all (doing so would actually be an error).

comment Calculating normal vector on a 2d pixelated map
What are you calling a 2d-map ? You talk about Worms, which is essentially a 1d map, at intersection point. A 2d-map would look like ericspitler.com/images/2d/normalmap.jpg. A 1d-map is like the first image at flipcode.com/archives/….

comment How do you calculate if 2 lines are facing toward or away?
I'm talking about two segments, not lines, so there is no "extension of the arrow". Also, it doesn't matter where the arrow points, as we are talking about distances here. The closest point on the black line could be a start/end point of the black line, it doesn't matter. The two segments could be collinears, this method would still works as intended. For bezier curves I mentionned it would give weird results depending of the curve's shape.

comment How can I generate Worms-style terrain?
I can't seem to edit a comment. Read "if(0.3<pixelValue<0.5)", obviously.

comment How can I generate Worms-style terrain?
I can't post pictures right now, but I'm just talking about a simple threshold filter à-la if(0.3>pixelValue>0.5) KeepIt();. The 'carefully' bit is about getting 0.3 and 0.5 right. You could also have a linear (or not) gradient, starting with high alpha at the top, gradually getting to 0 at the bottom, so you have room for a sky, and the ground is mostly filled up. Hope that helps.
