Hi,
I made a rectangle and want to animate it from (0, 0, 0) to (n, 0, 0) 2pixel
per a sec.
I found an update code and I call the method in here.
while(!viewer.done())
{
viewer.frame();
update(second);
}
but i don't know how to calculate it to meet the issue.
here's a part of update code.
void update(float dt)
{
myTimer += dt;
Vec3d currentPosition = transform[0]->getPosition();
Vec3d *newPosition;
newPosition = new Vec3d(currentPosition.x() + dt * ????,
currentPosition.y(), currentPosition.z());
object->setPosition(Vec3(newPosition->x(), newPosition->y(),
newPosition->z()));
}
I guess this line (newPosition = new Vec3d(currentPosition.x() + dt * ????,
currentPosition.y(), currentPosition.z());) is to animate the shape.
currentPosition.x() + dt * ??? <-- how ?
Sorry about posting very basic thing which is very hard to me. :(
anyone have any good link for me to understand the logic or can explan the
process?
Thank you!
Cheers,
Eungil,
