FRGMENTARIUM 3DICKULUS - Catmull-Rom spline paths ! camera/parameter keyframes !

[Patryk Kizny]

This looks sick!

[3dickulus]

latest changes/additions
[Spacebar] toggles animation (click in render window) + prefs checkbox for looping tnx Patryk

new easing curve management
if you have added easing curves to some variables they can be saved and used in a preset named "Range-nnnn-nnnn"
once a preset is created you can make changes in the gui and save another range
the keyword is "Range-" so nnnn-nnnn can also be a human readable name that makes sense like rot-0-100

keeping easing curves in Range-*** presets allows for the same variable to have different easing curves, currently need to be applied manually ie:apply range, render range, apply next range, render next range etc. but this should work well for GUI timeline control, with keyframes and morphranges kept in a file to be #included

so three preset types now
1> standard,   just parameters
2> keyframe,  camera control
3> range-nnn, parameter morphing

How to turn on spline path rendering? I've tried with "30 - Simple Key Frame Animation.frag" (and with some other key frame examples) and I don't see any red path (neither during animation nor during progressive mode). I have enabled "Draw spline paths for camera and target", "Spline Occlussion" options in the Preferences (everything is set to default).

I've tried with the latest version - Fragmentarium-1.0.6-Qt_5_3_2_MinGW. My OS is Windows 7 x64.

[3dickulus]

paths are rendered in "Progresive" "Stop" mode, I have just run a test here and all seems to work well, it was compiled on Win7 x64 so should be alright,

load tutorial 30
select "Progressive"
select "Stop" (so it is not rendering subframes)

I just tested like this and I see red blue and yellow lines ?

the latest is June 04 23:10:00, from late last night.

what gfx card?

do you have animotion? like it loads fine but just not drawing splines?

[_revers_]

Now it works! I didn't push the stop button earlier so the paths weren't visible.
I must admit, pretty clever solution with these paths! :]

[3dickulus]

tnx I will try to implement some other features as time permits but I'm having a lot of satisfaction from just wandering around in some of the frags that others have created

click-drag for the path control points
"Up" vectors on the camera path control points
an intutive timeline display/editor
distributed network rendering
depthbuffer save (suggested by Patryk) or heightmap load (as used elsewhere)

just to mention a few

[3dickulus]

A couple of things...

when a keyframe is selected from the pull-down menu
    the editor will automatically highlight the corresponding text, press F8 to replace with current camera settings
    the control point will also be highlighted on the spline path

infinite loop option in the preferences dialog and [SpaceBar] toggles play (tnx Patryk)

using courier 9pt fixed font for editor ( tnx cKleinhuis ) just testing, will enable user font selection in the preferences dialog

if no nVidia card is found the Edit->Shader Asm menu item is removed (tnx _revers_) now reports Vendor and Renderer

...and maybe squished a few bugs these are in the source as of the time of this post but I haven't had time to make a new win exe yet

EDIT: 2 exe files, one for nVidia + GL v4.1 (AsmBrowser), one for any gfx card + GL < v4.1 (no AsmBrowser)

Can I request a build and executable binaries for Mac OSX?
Thanks!

[3dickulus]

No, I don't have a Mac for development and testing, that will have to come from community support, but if you would like to donate one I'd be more than happy to give it a go.

[Patryk Kizny]

Thanks, got it. So some day I'll have to learn how to build myself. You keep tempting me on getting into cpp.

Does Frag support textureCube function? If yes, please show basic example.

[3dickulus]

the short answer is no edit: YES as of v2.0

have a look at the tutorial #25 Image Based Lighting.frag , this demonstrates how to use equirectangular maps for background and environment reflections

the long answer is yes, after the GL_Texture loading and mapping options have been added to the parser (Preprocessor.cpp/.h) and engine (DisplayWidget.cpp/.h)
this will also require adding to the C++ GL code an environment cube and code to handle management.
A lot of coding and testing to replicate something that is already available via equirectangular maps so it's not even on my radar right now. I also have to ask "How does this relate to exploring fractals and math?" which is my logic for deciding how much effort I am willing to put into the idea.

For anyone that has the GL C++ skills that wants to tackle this I would be happy to help familiarize them with the parts of the code they will need to look at and modify.
