Re: Sweet Home 3D 3.4

I have a question about putting stairs in: When you put them in, shouldn't they punch a "hole" in the floor above, or below them like windows and doors do?
I just added this feature in version 3.4 Beta 32.
This required a new property in the description file of the furniture of the catalog. I called it staircaseCutOutShape and it describes the shape used to cut out the ceiling and the floor of the upper levels when they intersect a staircase. This shape should be written with the syntax of the SVG path element described at http://www.w3.org/TR/SVG/paths.html (for example, M0,0 v1 h1 v-1 z describes a 1 unit wide square). This will allow to have complicated shapes like a pie shape for spiral staircases, as show in the following image and the attached document:



To let you import 3D models as staircases too, I added a new Staircase checkbox at the third step of the import furniture wizard and in the upcoming update of the Furniture Library Editor. In that case, the cut out shape of the staircase will be a rectangle with the same width and depth as the object itself.

I thought you had an icon for adding levels. Where did that go? I hope you won't be taking that out for the final version.
To avoid presenting too much features to beginners, the button and the level tabs are displayed only once you added a first level with... the Plan > Add level menu item.


I made a balcony with a floor but when you "walk" under it, you can see right through the floor like it isn't even there.
This behavior happens because you didn't create a ceiling at the lower level matching the bottom of the balcony, and OpenGL faces are visible only from one side. As I'm afraid of a flow of FAQs about this, I'm probably going to improve this behavior before releasing version 3.4. The idea would be to always create the opposite (ceiling) part of upper level floors, except at the places where the user drew a ceiling at the lower level. This is not so easy because it requires to compute some intersections between the user ceilings and these opposite parts, otherwise the superimposed surfaces won't be rendered correctly.

Re: Sweet Home 3D 3.4

Emmanuel,

Wow, another great feature!

I had a quick look at it, and it looks perfect. Right now, I don't have the time to thoroughly test it, hopefully that will come in the next few days.

Re: Sweet Home 3D 3.4

That stairs test worked great! I'm very excited about the new features and I can hardly wait until the release! :D But I know that great things can't be rushed. :D

Re: Sweet Home 3D 3.4

Great improvement, congratulations, Emmanuel, though when I downloaded the new version, I wish it was an update for the zoom problem in bird view mode ! Next time may be ? wink

Re: Sweet Home 3D 3.4

I updated the beta version to generate automatically the bottom part of a floor at upper levels, when no ceiling part was drawn at the lower level. It contains also a few bug fixes reported by a nice team of Swedish students who test Sweet Home 3D at this time. Nice job guys! smile

I wish it was an update for the zoom problem in bird view mode
Sorry I don't think I will change bird view mode anytime soon, except for this case.

Re: Sweet Home 3D 3.4

Thank you for your feedback. smile

I fixed a bug in the version 3.4 beta 37 to improve performances when you set textures on many different walls, rooms or furniture. Hope you can confirm it works better when you try to modify these objects (just trying to move them should make a difference).

Re: Sweet Home 3D 3.4

Emmanuel,

How many textures would you consider to be "many" textures?
I prepared a room with 20 boxes in it, all in all 30 different textures, with a compressed file size of 4.1 MB.
I made a second room with 82 different textures, and a compressed file size of 10.3 MB.
Is that enough?

Moving boxes is as smooth as I would expect.
Rendering in Q3 with just the ceiling light at 800x800 is fast.
The 3D preview rotates smoothly as well.

I can share the file(s), or prepare an even bigger one.

Hans

Re: Sweet Home 3D 3.4

Thank you for your tests.

[...] Is that enough?
I would say it depends on the power of your processor. Recently, some users complained about some performance regression and the bug I found could lead to some performance loss. But the slowing effect could take place only when trying to compute 3D updates, after moving wall, rooms or furniture which use some texture, or changing their size. Rendering speed won't get faster in the photo creation dialog.

Re: Sweet Home 3D 3.4

Emmanuel,

I have a dual core machine, not sure which processor exactly, about 3-4 yrs old.
Maybe the problem is mainly with "older" machines with even lower specs?
