Hi

I would be super grateful for some advice regarding Fragmentarium- I wish to make some simple animations of fractals by just export a sequence of jpeg/png etc but cant figure out how to do it? I have managed to export 1 picture but it is of the whole application (like a screen shot) rather than the just the image being rendered.

if anyone could just give a simple example of how to animate the fractals and then export them as images I would be very grtaeful!

Thanks

Alan

Animation is *very* primitive at the moment.

Try opening the 'Tutorials / Dynamic System.frag" system. This system uses the 'uniform float time;' variable to create a simple animation.
Now press the animation button. When you move the slider, you can see the system react, and you can set the desired frames per second, and animation length.

If you now press the record button (the 'o' button), the system will ask for filename. Specify a filename (e.g. "anim.png"), and Fragmentarium will start saving images (named "anim1.jpg", "anim2.jpg", "anim3.jpg",...) for each frame.

So if you want do a fractal animation, you must programmatically set some parameters (e.g. a rotation, or other parameter) based on the 'time' variable.

Hi

Many thanks the reply! Playing around with  'time' variable and looking good- need some advice with the output however, my renders look like the attached jpgs instead of a normal fullscreen render like the link below

appreciate the help--and thanks for this great app!

Glad you liked it :-) But there is something very puzzling with your first image - I just grab the OpenGL framebuffer and store it as a file, so all the user interface widgets should not be present?

What happens if you do a 'Render | High Resolution Render...' - does the image here turn out okay (it is captured the same way as above, and stitched together)?
