Getting current position of the point

[Travnick]

there is function

Code: [Select]

Polygon.GetPointPosition(i)

but it only returns posiotion which was defined at the creating shape.

i wanna get actual position of points that is actualy rendered on the screen (shape was moved, rotated, scaled etc. and i wanna know where exactly is my point on the screen)

as far as I found there is

Code: [Select]

const Matrix3& GetMatrix() const;
and it probably contains what I want, but this function is protected

any solution?

The points are still right, but relative to the Shape Position, i think you could do it easy calculating yourself

Not sure if there is any other way : )

[Travnick]

I can calculate them, but it will be wasting time, because positions have been already calculated (they are rendered at this positions)

[Grimshaw]

They are calculated by opengl every draw using the transform matrix for the vertex set.

Code: [Select]

Polygon.TransformToGlobal(point);

sounds nice, I'll check it
thx
