DeleD Community Edition

[Paul-Jan]

Hi Guys,

While Jeroen is working very hard on the new internal structure of DeleD, I am trying to put together the new 1.34 version, to be released in November. One of the things I am working on is improving the basic face editing functionality, so far here is what I got done:

Remember how scaling the u, v coordinates of multiple faces made the continuous texture pattern break up? Not any longer.


Proper rotation of texture coordinates, either through dragging in the 2d views or the command properties dialog, has been implemented. On the screenshot below, you can see a 45 degrees rotated wall texture mapped on the DeleD text primitive.


Last but not least, the command properties dialog for face u, v scaling has been implemented. Finally, you can do a precise job on scaling those u, v coordinates!

Technical blab (feel free to skip ): I am now working on improving the planar mapping algorithm. The current algorithm generates bigger coordinates for vertices that are further away from the absolute center of the scene. This is making manual rotation and scaling (dragging in the 2D views) a bit of a pain whenever the edited object is far from the center. DeleD 1.33 solved this issue by scaling around the center of the polygon, but this used to cause discontinuities in the textures. By rewriting the planar mapping to always generate wrapping coordinates around 0,0 , I hope to keep everything nice and convenient.

This is what I've been waiting for.

Oooh ooh ooh, can you make sure to add an option in the options window to have universal scaling of UV coords. So if we have built our levels slightly too big or too small, we can adjust the uv coords while still using the auto-uv option.

hpesoj: I knew you were going to ask for that! Yes, I am adding an optional setting for that to the interface as well

Vampyre: Define "messed up"? They will not perfectly align where faces meet that are mapped on different planes (i.e. where slightly more horizontal meets slightly more vertical). Planar mapping does that, getting that 'fixed' (texture unwrapping functionality) is not exactly what this announcement is about

YES, that should make things easier. I'll be looking forward to it.

Vampyre: None taken! You have a good point there! Although the alignment of textures in between faces that are mapped on different planes will never be perfect with a simple planar mapping scheme, the actual alignment of the textures itself could definitely use some improvement! I'll get to it right away, and will post a new thread about it

[edit]Decided not to start a new thread, see post below this one[/edit]

Thanks Vampyre for reminding us of the mirrored texturing, I slightly improved the algorithm so that the textures are never mirrored (see the screenshot below... which is actually a little too small so you'll have to take my word for it ):



I (arbitrarily) made the texturing direction now stay the same when you rotate the object around the x axis, on rotation around the other axes there are discontinuities in the direction (which, unless I am more mathematically challenged than I'd like to think I am, is not solvable)
