Circle geometric primitive

[tom95521]

It would be great if PTE had a circle geometric primitive. I can simulate a circle by rotating object rotated 1 degree, then copying object, and pasting 180 times. It is a very accurate circle but PTE must rotate 180 objects to create. Zoom effect slower due to large number of objects that must be scaled and transformed instead of 1 object. Other method might be with use of circular mask but it would still be nice to have a simple circle object with lower computing requirements.

Test circle created by rectangle rotation.

Thanks,

Hi Tom,

Couple of points:

Wouldn't it be easier to use a PNG circle made in that Adobe Product?

Why are the Bear and the Butterfly included in the Template?

Hi DG,

Not sure where you see a bear and butterfly. I probably should have used a simple gradient background instead of windows wallpaper.

I think a PTE generated circle would be easier to change the color and also scale up/down with less noticeable jagged edges. I guess if I set the external editor it would not take too long but still not as simple as a PTE circle object.

Also maybe you know how I could make an ellipse instead of circle by rotating an object in PTE? I was just wondering if it is possible? I thought by rotation off center it would create an ellipse but no luck so far.

Thanks,

Tom

The downloaded Template when opened up, includes, but does not use:

Lake.wmv

Bear.wmv

Butterfly.wmv

Use frames to create the ellipse.

Change the vertical axis of the FRAME without changing the horizontal axis.

I would like to second Tom's suggestion on circles as geometric primitives, of course with color options as they are for rectangles. Dave's example does not really work with respect to colors, as PTE does not provide additive mixing.

Because it doesn't work - I have removed it.

We already have this option :rolleyes:/>/>

Just use a circular Mask with a hard edge.

You can then insert any image, change colour (with a rectangle), zoom, change opacity etc.

Also easy to change to an elispe by dragging the edges of the Mask Circle

All very easy.

Hi DG,

I'm sorry I didn't get a chance to download and view before you removed it. I always learn something from your demo slideshows.

I don't know why I didn't think of a frame to make the ellipse. It was early in the morning and before my first cup of Starbucks coffee.

The screen aspect ratio is critical if you want to create a perfect circle, but it is another method to create an ellipse.

During my circle testing I think I found a 60 fps encoding bug in 7.5 that I will post in the main forum.

Thanks,

Tom

Very nice Jill. That is a very good demo. I was hoping to avoid using a mask since it might be nice to have many circles on the screen at one time and then apply a blur (PTE 7.6 high on wish list) like a bokeh effect. Maybe there is not such a performance hit as I think there is for masks.

Thanks,

Yes, it's an easy and obvious construction, but it isn't really the same (beside performance aspects). The circle based on a mask cannot be placed into a mask container, and that's the place where I like circles to be

Tom,

Watch out for a PM.

Might as well include other part of this request before I forget - circular gradient. Not much use having a circle if you can't make it appear to have depth.

Thanks,

Tom
