Hi All,

I try to make a flying bird... I would like to hear your ideas about it :) Thanks in advance...

Very nice!! You've really captured the feeling of flight. Even though there is little detail in the model and no background, I can tell from the movement that the bird is gliding. It looks a lot like a seagull.

It would be nice to see a series like this done to the same level. Maybe a hummingbird, owl, penguin, ostrich, robin, etc.

The soaring parts look great!!

It's nice and the floating bits are great. But the flapping seems too simple and cartoony. A bird twists its wing while flapping.

With the downward movement it twists the wing forward. So the leading edge of the wing goes down faster than the trailing egde. And this effect is stronger att he wingtip than at the roots. I hope you understand what I mean. It's a complicated movement to animate correctly. Good luck! :thumbsup:

Fantastic sence of movement....very convincing.

The only thing i would note tho, and this may tie in to what skyraider is saying, the bird appears to be trying too hard...like its not used to flying. Unless it was hurt or flying against some strong wind, the actual flapping should be appear smooth, natural and effortless. But this would only take minor tweaks, you seem to have the hard parts taken care of.

excellent work!

heheh thanks guys:) I didn`t do any background but I imagined it is flying over a sea under wind :)
Thanks for your positive comments :)

Yeah your imagination works out really well. Have some blurred animation of a wavy sea in the background, lighting, textures, and you're there :)

The gliding seems to be perfect. I like the lift of the wing tip (as if the wind gets under him) prior to the last glide towards the camera. It's a very convincing soar even with a very simple model.

However, the flapping of the wings needs some work. First I think the flapping motion is too fast for this size of a bird. It looks like a seagull but you have it flapping its wings as if it were a sparrow. Secondly, as mentioned already, you need more rotation of the wing as it flaps. It gives an impression of a piece of rubber being wobbled up and down. A bird actually strokes (much like a swimmer) through the air. Fold the wings in a bit on the upstroke and add the secondary action in the wingtips as suggested on the downstroke.

The head doesn't have to remain stationary while in flight, but some action in the body would help define the lift from the wings. The force of a wing flap will drive the birds body up and down. The head will persist in a generally static position but will move a bit depending on the amount of force affecting the body.

Keep going with it ... I think you are definately on the right path.

I really though you got the movement good, but since there are others who disagree....

Igor, same problem: the wings are too rigid. They should twist to get the right lift at the right time...
