Hi there,

I wonder if it is possible to at all to use animated textures?
I.e load a sequence of images into a texture or literally a movie?

Currently I'm getting around that using loading images on 'per frame' basis. That's cool for rendering, but not necessarily for previewing.

The second question, I think I've heard somewhere about full 3D textures in OpenGL. Anybody heard something?
Would that be possible to have these in shaders?

I am thinking along the lines of rendering some pointcloud data, saving into texture sequences and then making use of that stuff in Frag.

yes I demonstrated that very idea to you and provided a script that did it, and instructions.
I found the thread for you http://www.fractalforums.com/index.php?topic=21985.msg86050#msg86050
the rest is up to you...

...and yes, 3D textures are very do-able but I'm going to have to let you spin on that for a while wink

just thinking out loud here...

the limit per sequence would be the number of layers in a 3D texture and image size would be the maximum 3D texture XY dimension, in the case of my hardware that would be 2048 @ 2048x2048 layers in sequence for playback.

need to read folder full of images into a single 3D texture or into a list of 2D textures and figure out a nice way to represent this in the parser and fragment code, the time tick can address the sequence in the frag, 2D textures would not have the same limitations as 3D textures

pointcloud can be a simple pos+color elements list and no texture needed, why not just load the pointcloud into frag space?

where does the pointcloud data come form?
how does point cloud data get saved to texture sequence?
what is the desired effect or purpose?

I have been thinking of this and the only issue I have with it is how does this help me explore fractals  huh?

Yeah, you're probably right.
If it's not there and if it requires coding handling pointclouds data can be perhaps done in an easier way - i.e. Reading directly from the file. Pointclouds are easy - apart from the proprietary formats, all you need is read a csv-like ascii format and provide some way of mapping fields.

Simplest pointclouds data is xyzi data with I being intensity.
What would be cooler though would be being able to create a 3D Tex in frag, render a fractal into it and write to pointclouds.

that might be a whole other program with different functionality than Fragmentarium
